Commercial Invoice for Customs 2026: What Every Freight Forwarder Must Include to Avoid Cost Overruns
Introduction
A commercial invoice for customs is the legal declaration of goods, value, and origin that CBP and every foreign customs authority uses to calculate duty, apply the HS or HTS classification, and clear the shipment. Missing or misstated fields on the invoice are the single largest source of avoidable customs cost overruns in 2026. Undervaluation triggers penalty exposure. A wrong HS code changes the duty rate. A missing country of origin flips a Section 301 exposure open. A missing freight breakout can push CBP to reclassify the transaction value.
Key Takeaways
- A commercial invoice for customs is the legal document CBP reads to calculate import duty, MPF, and HMF, and to decide whether the shipment clears, is held for review, or is flagged for penalty.
- Every US import commercial invoice must include 14 fields: buyer and seller, invoice number and date, HTS classification per line, country of origin per line, unit price, quantity, net weight, currency, incoterm, freight, insurance, discount if any, total value, and signature.
- Four errors drive most cost overruns: undervaluation of the goods, wrong HS or HTS classification, missing country of origin, and freight or insurance combined into the goods value without a separate line.
- Whether freight and insurance belong in the "commercial invoice value" depends on the incoterm. FOB values exclude international freight and insurance. CIF values include them. CBP calculates duty on transaction value at the port of export, which is usually FOB.
- Commercial invoice OCR and template automation cut field errors and match the invoice against the entry, the packing list, and the bill of lading before the entry is filed. This is the single highest leverage automation on the customs cost line.
- CBP requires the importer of record to retain the commercial invoice for 5 years after entry. Electronic records satisfy the retention rule under 19 CFR 163.5.
This guide covers what a commercial invoice for customs actually is in 2026, the difference between a commercial invoice, a customs invoice, and a proforma invoice, the 14 required fields, how the invoice drives duty and fee calculation with a worked example, the 8 most common invoice errors and their cost consequence, the HS or HTS classification rule, the country of origin rule, what counts as "commercial invoice value," how to fill one out step by step, and how forwarders automate the workflow.
What Is a Commercial Invoice for Customs?
A commercial invoice for customs is the seller's legal declaration to the buyer, and to the customs authority at both ends of the trade, that a specific shipment of goods has been sold at a specific price under specific terms. It is the document the customs authority reads to calculate duty, verify HS or HTS classification, confirm country of origin, and match the shipment against the entry filing. Every international shipment above the informal entry threshold requires one.
The shipper view
A shipper prepares the commercial invoice, usually from an ERP or an accounting system. The invoice names the buyer and seller, lists every line item with its unit price and quantity, states the country of origin per line, states the HS or HTS classification, states the incoterm, states freight and insurance separately if the incoterm requires it, and totals in the transaction currency. The invoice travels with the packing list and the bill of lading or air waybill in the shipment file.
The forwarder view
A forwarder or licensed customs broker reads the commercial invoice to file the customs entry. The invoice values, HS codes, country of origin, and incoterm feed directly into CBP Form 3461 (entry) and CBP Form 7501 (entry summary). Errors on the invoice surface as errors on the entry, which triggers CBP holds, information requests, or, in the worst case, a valuation reclassification and a penalty. For the ocean import workflow that ties the commercial invoice, the ISF, the AMS filing, and the entry together inside a single shipment record, see Ocean Import Freight Management Software.
Commercial Invoice vs Customs Invoice vs Proforma Invoice
The three invoice types serve different purposes in an international shipment. Confusing them is the most common documentation error in a forwarder file, and the highest volume question hitting this URL from Bing Copilot ("commercial invoice vs customs invoice" at 28 impressions, "customs invoice vs commercial invoice" at 20 impressions, "is customs invoice same as commercial invoice" at 6 impressions).
| Invoice Type | Purpose | When It Is Issued | Clears Customs? |
|---|---|---|---|
| Commercial Invoice | Legal declaration of a completed sale, presented to customs to calculate duty and clear the shipment. | After the goods are sold and ready to ship. The invoice reflects the actual transaction value. | Yes. This is the invoice CBP reads on every commercial entry. |
| Customs Invoice | The commercial invoice reformatted to meet the destination country's customs data requirements (e.g., a Canada Customs Invoice or a country specific form). | At export, if the destination country requires a specific invoice format on top of the seller's own commercial invoice. | Yes. In most countries the commercial invoice already satisfies the customs invoice requirement. A separate customs invoice is only required where the destination law says so. |
| Proforma Invoice | A preliminary quote issued before the sale. Names goods, estimated prices, and terms, so the buyer can arrange financing, obtain an import license, or open a letter of credit. | Before the sale is finalised. Values are estimates, not the transaction record. | No. A proforma invoice is not accepted by CBP as the entry document. It cannot substitute for the commercial invoice at clearance. |
Short answer: the customs invoice and the commercial invoice are almost always the same document. The proforma is the pre sale quote. Only the commercial invoice clears customs.
What Every Commercial Invoice Must Include: 14 Required Fields in 2026
CBP guidance under 19 CFR 141.86 lists the required content of a commercial invoice for a US import. The same 14 fields also satisfy the customs requirements in the EU, UK, Canada, Australia, and most Asian markets. The list below covers what every field is, what data it holds, and why customs needs it.
| Field | Required Data | Why Customs Needs It |
|---|---|---|
| 1. Seller (Exporter) | Full legal name, address, tax ID or EIN, and contact. | Identifies the party that owns the goods at the port of export. |
| 2. Buyer (Importer of Record) | Full legal name, address, IOR number (for US imports, EIN or SSN), and contact. | Identifies the party responsible for duty payment and record retention. |
| 3. Invoice Number | Unique reference issued by the seller. | Ties the entry to the seller's accounting record and to any letter of credit. |
| 4. Invoice Date | Date the invoice was issued. | Establishes the exchange rate reference date if the invoice is not in USD. |
| 5. Incoterm | The Incoterms 2020 rule that governs the sale (FOB, CIF, EXW, DAP, DDP, etc.). | Tells CBP where risk and cost transfer, which determines whether freight and insurance sit inside or outside the transaction value. |
| 6. Currency | The transaction currency (USD, EUR, CNY, etc.). | CBP converts to USD at the entry date using the published exchange rate. |
| 7. Line Item Description | Specific commercial description of each product line (not generic "goods" or "parts"). | CBP uses the description to verify the declared HS or HTS classification. |
| 8. HS or HTS Classification | 10 digit HTS code per line for US imports, 6 digit HS code for other destinations. | The classification determines the duty rate. This is the highest impact field on the invoice. |
| 9. Country of Origin | Country where the goods were substantially transformed, per line. | Drives Section 301 tariff exposure on Chinese origin goods, and drives Free Trade Agreement duty savings. |
| 10. Unit Price | Price per unit at the port of export, in the transaction currency. | Feeds the transaction value that CBP uses to calculate duty. |
| 11. Quantity and Unit | Number of units per line, plus unit of measure (pieces, kilograms, litres, etc.). | Verifies the shipment against the packing list and the bill of lading. |
| 12. Net and Gross Weight | Net and gross weight per line and total, in kilograms. | Verifies against carrier documentation and supports certain HTS classifications that key on weight. |
| 13. Freight, Insurance, and Discounts | Separate line for international freight, insurance, and any trade discount. | Under CIF terms, freight and insurance are inside the transaction value. Under FOB, they are outside. CBP needs the split to calculate the correct base. |
| 14. Total Value and Signature | Total invoice value in the transaction currency, signed by an authorised representative of the seller. | Establishes the declared transaction value that CBP uses to calculate MPF and HMF, and to check against the entry. |
Payment terms (net 30, letter of credit, TT, etc.) are not required by CBP for entry, but most forwarders and shippers include them in field 3 or as a separate line to keep the invoice aligned with the sales contract.
How the Commercial Invoice Drives Duty and Fee Calculation
Every US import duty and fee amount starts from a field on the commercial invoice. The invoice supplies the base value, the HTS classification determines the duty rate, and the country of origin decides whether Section 301, IEEPA, or a Free Trade Agreement rate applies. Below is a worked example on a 100,000 USD Chinese origin electronics entry, followed by the cost impact of the three most common invoice errors.
Worked example: 100,000 USD Chinese origin consumer electronics, ocean FCL, DDP not used
| Line | Rate | Base | Amount (USD) |
|---|---|---|---|
| Transaction value (FOB, from invoice) | 100,000.00 | ||
| Base import duty (HTS 8517.62.0090) | 0 percent | 100,000.00 | 0.00 |
| Section 301 tariff (China origin) | 25 percent | 100,000.00 | 25,000.00 |
| Merchandise Processing Fee (MPF) | 0.3464 percent | 100,000.00 | 346.40 (capped at 634.62) |
| Harbor Maintenance Fee (HMF) | 0.125 percent | 100,000.00 | 125.00 |
| Total customs cost | 25,471.40 |
Cost impact of three common invoice errors on the same 100,000 USD entry
| Invoice Error | What Changes | Cost Consequence |
|---|---|---|
| HTS code wrong by one chapter (declared 8517, actually 8528 at 5 percent base duty) | Duty rate rises from 0 percent base to 5 percent base, on top of the Section 301 rate. | +5,000 USD in duty, plus back duty and penalty exposure at post entry audit. |
| Country of origin declared as Vietnam but goods are Chinese origin | Section 301 25 percent tariff should apply but is not paid at entry. | +25,000 USD back duty when CBP catches the discrepancy, plus civil penalty up to two times the loss of duty (up to 50,000 USD) under 19 USC 1592. |
| Invoice value understated by 10 percent (declared 90,000, actual 100,000) | Duty and Section 301 base value both drop 10 percent at entry. | Short pay of 2,500 USD in duty, exposure to loss of duty penalty at 2x the shortfall plus fraud penalty at up to 4x under 19 USC 1592. |
Every one of the three errors above is a commercial invoice field error, not an entry filing error. This is why the customs cost line moves when the invoice moves. For the filing platform that pulls invoice fields into the entry, catches HTS and country of origin mismatches before submission, and posts duty via ACH Direct, see Customs Management Software for Forwarders.
HS Code and HTS Code on the Commercial Invoice
HS and HTS are two of the most searched invoice topics in the GSC set (63 impressions for "what is hs code on commercial invoice," 20 impressions for "is hs code required on commercial invoice"). The two codes are related but not the same.
What is the HS code?
The Harmonized System (HS) code is a 6 digit international product classification issued by the World Customs Organization. Over 200 countries use it. The first 2 digits identify the chapter, the next 2 identify the heading, the last 2 identify the subheading.
What is the HTS code?
The Harmonized Tariff Schedule (HTS) code is the 10 digit US import version. The first 6 digits match the international HS code. The last 4 digits are US specific and drive the exact duty rate. Every US import commercial invoice must state the 10 digit HTS per line.
Is the HS code required on the commercial invoice?
Yes for US imports. CBP requires the 10 digit HTS code on the commercial invoice or on the entry documentation. Most forwarders put the HTS code on the invoice line itself, so the entry filer can read and file without an extra document lookup. For a full explainer on how HS codes work and how to look them up, see the Harmonized System (HS) Codes Explained guide.
Country of Origin on the Commercial Invoice
Country of origin is the country in which the goods were substantially transformed, not necessarily the country of export. A shirt sewn in Bangladesh from Chinese fabric has China as the country of the fabric and Bangladesh as the country of substantial transformation, which makes Bangladesh the country of origin for CBP purposes.
Country of origin vs country of export
Country of export is the country the goods leave from. Country of origin is where they were substantially transformed. The two are often different for goods routed through a distribution hub like Singapore, Hong Kong, or a Free Trade Zone. Only country of origin determines the duty rate.
Why country of origin drives cost
Section 301 tariffs of up to 25 percent apply on Chinese origin goods. Free Trade Agreements (USMCA, KORUS, US Australia FTA) can reduce or eliminate duty on qualifying goods. Both mechanics key on the country of origin field on the commercial invoice, not the country of shipment. Misdeclaring country of origin is the second highest cost customs error in 2026 after HTS misclassification. For qualifying FTA claims, the certificate of origin travels with the commercial invoice at entry. See Free Trade Agreement and the Importance of Certificate of Origin for the certificate mechanics.
What Counts as Commercial Invoice Value, and What Does Not
"Commercial invoice value" is one of the top three question themes in the Bing set (multiple queries on freight, packaging, service, and installation cost inclusion). The answer depends on the incoterm and on the CBP transaction value rule under 19 CFR 152.
Transaction value rule (default)
CBP calculates duty on the "transaction value" of the goods, which is the price actually paid or payable when sold for export to the United States, plus statutory additions (packing costs, selling commissions, assists, royalties, and any part of the proceeds of resale). Transaction value is the CBP default and covers most commercial entries.
Should freight cost be on the commercial invoice?
Under FOB, EXW, and FCA incoterms, international freight is not part of the goods value. It must still be listed on the commercial invoice as a separate line, but it is not part of the dutiable value. Under CIF, CIP, DAP, and DDP incoterms, freight is inside the price, so CBP deducts it out to arrive at the FOB equivalent for duty calculation. Short answer: yes, freight belongs on the invoice as a separate line. It is dutiable only if the incoterm is CIF or similar and no separate deduction is possible.
Should shipping cost, insurance, and packaging be on the commercial invoice?
Insurance and shipping follow the freight rule (dutiable under CIF, deductible under FOB, always disclosed as a separate line). Packaging cost is included in transaction value only when it is a cost of the sale, not a domestic post arrival cost. If the packaging is done in the US after import, it is not on the commercial invoice. If the packaging is done at origin and is part of the sale, it is on the commercial invoice.
Sales price or cost of goods?
The commercial invoice reports the actual sales price to the buyer, not the seller's cost of goods. CBP wants the transaction value between the buyer and the seller, which is the sales price. If the shipment is a sample, a replacement, or a warranty return where no sale has occurred, the invoice must still state a fair market value, even though no money changes hands, and must clearly note "for customs purposes only, no commercial value" or the equivalent.
Common Commercial Invoice Errors That Cause Cost Overruns
The eight errors below account for most cost overruns on the customs line. Each is fixable at the invoice preparation stage. Each becomes expensive if it lands in the CBP entry.
| Error | Customs Consequence | Fix |
|---|---|---|
| Undervaluation of goods | Loss of duty penalty at up to 2x the shortfall (negligence) or 4x (fraud) under 19 USC 1592. | State the actual transaction value. If free of charge, state fair market value and mark "for customs purposes only, no commercial value." |
| Wrong HS or HTS code | Higher duty rate, back duty at post entry audit, and civil penalty exposure. | Classify per line at the 10 digit HTS level. Cross check against CBP CROSS rulings for close cases. |
| Missing or wrong country of origin | Section 301 exposure of up to 25 percent on Chinese origin goods declared as Vietnamese, or loss of an FTA duty saving. | State country of substantial transformation per line, not country of export. Attach the certificate of origin for FTA claims. |
| Freight or insurance combined into goods value with no separate line | CBP may treat the full invoice as CIF and apply duty on freight plus insurance. | List freight, insurance, and discounts as separate lines. State the incoterm clearly. |
| Generic product description ("goods," "parts," "electronics") | CBP information request, entry hold, and a delay of 1 to 3 business days while the broker clarifies. | State a specific commercial description per line ("Bluetooth wireless earbuds, model X-100"). |
| Payment terms or currency missing | Entry hold if the currency is unclear. Broker information request. | State currency and payment terms on every invoice. Use the ISO currency code (USD, EUR, CNY). |
| Invoice date after entry date | CBP applies a different exchange rate than the one on the sales contract, which can shift duty. | Issue the invoice on or before the shipment date. Never post date the invoice. |
| Signature missing | CBP information request. Some ports refuse the entry. | Sign every commercial invoice or include a printed name and role of the authorised representative of the seller. |
Watch out
A commercial invoice that reaches the customs broker after the ISF filing deadline pushes ISF into the late window, and CBP assesses the 5,000 USD ISF penalty per violation. Most late ISF penalties are the result of a foreign supplier delaying the commercial invoice past the 24 hour pre departure cutoff, not the broker missing the filing. Forwarders with an automated document workflow can prompt the supplier a day early and catch the missing invoice before the deadline lapses.
How to Fill Out a Commercial Invoice for Customs, Step by Step
The steps below build a commercial invoice that meets US CBP requirements under 19 CFR 141.86 and satisfies the customs requirements in the EU, UK, Canada, Australia, and most Asian markets.
Step 1: Buyer and seller block
Enter the seller (exporter) block at top left: full legal name, address, tax ID or EIN, contact name, phone, and email. Enter the buyer (importer of record) block at top right: full legal name, address, IOR number, contact name, phone, and email. Both blocks must be complete for CBP to accept the invoice.
Step 2: Shipment identifiers
Enter the invoice number, invoice date, purchase order number, shipment reference number, bill of lading or air waybill number, and the port of loading and discharge. These identifiers tie the invoice to the packing list, the carrier document, and the CBP entry.
Step 3: Incoterm and payment terms
State the Incoterms 2020 rule that governs the sale (FOB Shanghai, CIF Los Angeles, EXW Guangzhou, DAP Chicago, DDP Newark, etc.). State the payment terms (net 30, TT, letter of credit). The incoterm determines whether freight and insurance sit inside or outside the dutiable value.
Step 4: Line items
List every product line with a specific commercial description, the 10 digit HTS code (US imports), the country of origin, the quantity, the unit of measure, the unit price, the extended line total, the net weight, and the gross weight. One line per product. Do not combine dissimilar products on one line.
Step 5: Freight, insurance, discount
Enter international freight, insurance, and any trade discount as separate lines below the product lines. These are dutiable only under CIF style incoterms. Under FOB style incoterms, they must still be disclosed but they are not part of the transaction value CBP uses to calculate duty.
Step 6: Totals and currency
State the total invoice value, in the transaction currency, at the bottom of the line item block. Include the currency code (USD, EUR, CNY). CBP converts to USD at the entry date using the CBP quarterly exchange rate.
Step 7: Signature
Sign the invoice or include a printed name and role of the authorised representative of the seller. State "I certify the information on this commercial invoice is true and correct."
Air Import Commercial Invoice Notes
Air imports move faster than ocean, so the commercial invoice must be complete at the point of AWB issuance, not after. Air AMS is due 4 hours before US arrival on long haul flights and at wheels up on short haul flights under 4 hours. A missing HTS code, a missing country of origin, or a missing signature at the point of AWB issuance can hold the shipment on landing.
Express air couriers (DHL, FedEx, UPS) typically self file the entry for shipments under 2,500 USD (Type 11 informal) and pull the commercial invoice from the shipper's ERP or the courier portal. For higher value air shipments (Type 01 formal), a licensed customs broker files the entry using the commercial invoice values, and the same field discipline applies. For the air import shipment record that pulls the commercial invoice, HTS classification, and country of origin into the entry filing, see Air Import Freight Management Software.
Automating the Commercial Invoice: OCR, Templates, and Forwarder Integrations
Manual commercial invoice preparation is the single highest source of customs field errors in a forwarder's workflow. Three automation layers cut the error rate meaningfully.
OCR extraction
Optical character recognition reads a supplier's PDF invoice and extracts the buyer, seller, invoice number, line items, HTS code, country of origin, and totals into a structured record. Modern freight software OCR reaches 95 percent field accuracy on standard invoices and 85 percent on non standard formats. Every extracted field is validated against the entry rules before the entry is filed.
Templates
A forwarder issued commercial invoice template lets the shipper fill fields into a form that already carries the correct field labels, the required incoterm dropdown, the HTS code lookup, and the country of origin dropdown. Field errors drop by an order of magnitude compared with free form supplier PDFs.
Integration with the entry filing system
The highest leverage layer is the integration that pushes the extracted invoice fields directly into the CBP entry, matches them against the packing list and the bill of lading, and flags any mismatch before the entry is filed. This is where the customs cost line moves the most, because every mismatch caught pre filing is a hold, a penalty, or a back duty avoided post filing. For the integration surface that connects the commercial invoice, the ISF, the AMS filing, and the CBP entry inside one shipment record, see Freight Integrations Software for Forwarders.
Compliance and Record Retention
Under 19 CFR 163, the importer of record must retain the commercial invoice, along with the entry documents, the packing list, the bill of lading, and the payment record, for 5 years after the date of entry. Electronic records satisfy the retention rule under 19 CFR 163.5. During a CBP post release audit, the importer must be able to produce the commercial invoice on request, and the audit will match invoice value, HTS classification, and country of origin against the CBP Form 7501 entry summary.
Forwarders typically retain the commercial invoice as part of the shipment record in the freight management system, alongside the entry, the ISF, the AMS filing, and the delivery order. Retention is automatic and the record is retrievable by shipment reference, entry number, or buyer name.
Frequently Asked Questions
What is a commercial invoice for customs?
A commercial invoice for customs is the seller's legal declaration of a completed sale, presented to the customs authority so it can calculate import duty, verify HS or HTS classification, confirm country of origin, and clear the shipment. Every international commercial shipment above the informal entry threshold requires one, and CBP reads the invoice on every US import entry.
What is the difference between a commercial invoice and a customs invoice?
In most cases the commercial invoice is the customs invoice. The two terms are used interchangeably. A "customs invoice" only means something different when the destination country requires a country specific form (for example, the Canada Customs Invoice), in which case that form is prepared in addition to, or in place of, the seller's own commercial invoice. Everywhere else, the commercial invoice satisfies the customs requirement on its own.
Does a commercial invoice include freight cost?
Yes, as a disclosed separate line. Whether the freight cost is part of the dutiable value depends on the incoterm. Under FOB, EXW, and FCA, freight is disclosed but not dutiable. Under CIF, CIP, DAP, and DDP, freight is inside the price and CBP deducts it out to reach the FOB equivalent for duty calculation. Always list freight on the invoice, and always name the incoterm so CBP can apply the correct rule.
Should shipping cost be included in the commercial invoice?
Yes, on a separate line. Shipping cost, insurance, and any trade discount must appear on the commercial invoice, even if they are not dutiable under the incoterm. CBP needs the split to calculate the correct transaction value. Combining shipping into the goods value with no separate line triggers CBP to treat the full amount as dutiable.
What is an HS code on a commercial invoice, and is it required?
The HS code is the 6 digit Harmonized System product classification used by 200+ countries. For US imports the 10 digit HTS code (Harmonized Tariff Schedule) is required on the commercial invoice or the entry documentation. Most forwarders put the HTS code on the invoice line itself so the entry filer can classify without an extra lookup. The HTS code determines the duty rate, which makes it the highest impact field on the invoice.
How is customs duty calculated from a commercial invoice?
Customs duty is calculated by multiplying the transaction value on the commercial invoice by the HTS duty rate for the classification, then adding any Section 301 tariff (China origin), any IEEPA duty, any Free Trade Agreement adjustment, plus Merchandise Processing Fee (0.3464 percent, capped at 634.62 USD per entry in 2026) and Harbor Maintenance Fee (0.125 percent on ocean cargo only). The commercial invoice is the input to every one of those line calculations.
What is "commercial invoice value" for customs purposes?
Commercial invoice value is the transaction value of the goods, defined by CBP as the price actually paid or payable when sold for export to the US, plus statutory additions (packing costs, selling commissions, assists, royalties). It is not the seller's cost of goods. It is not the retail sell price to a downstream buyer. It is the price between the exporter and the US importer at the port of export.
Should the commercial invoice show cost of goods or the sales price?
The sales price between the exporter and the US importer. That is the transaction value CBP applies duty to. Cost of goods is an internal accounting figure and is not accepted for customs valuation. If the goods are a sample, warranty return, or free of charge, the invoice must still state a fair market value and note "for customs purposes only, no commercial value."
Where does country of origin go on the commercial invoice?
Country of origin is stated per line, next to the HTS code and the product description. Country of origin is the country of substantial transformation, not the country of export. A shirt sewn in Bangladesh from Chinese fabric has Bangladesh as country of origin. Country of origin drives Section 301 exposure and Free Trade Agreement duty savings, which makes it the second most cost sensitive field on the invoice.
What are the most common commercial invoice mistakes that cause customs holds?
The top eight are undervaluation of the goods, wrong HS or HTS code, missing or wrong country of origin, freight or insurance combined into the goods value with no separate line, generic product description ("goods," "parts"), missing currency or payment terms, invoice date after the entry date, and missing signature. Each error is fixable at invoice preparation. Each error becomes expensive if it lands in the CBP entry.
What is the difference between a commercial invoice and a proforma invoice?
A proforma invoice is a pre sale quote issued before the transaction is finalised. It lets the buyer arrange financing, obtain an import license, or open a letter of credit. Values are estimates. It is not accepted by CBP as the entry document. A commercial invoice is the post sale legal declaration of the actual transaction, and it is the invoice CBP reads on every commercial entry.
Do sample shipments need a cost on the commercial invoice?
Yes. Even a sample or free of charge shipment must show a fair market value on the commercial invoice, so CBP can calculate duty. The invoice must clearly state "for customs purposes only, no commercial value" or the equivalent. Zero value invoices are rejected by CBP and by most foreign customs authorities.
How do I fill out a commercial invoice for customs clearance?
Complete the buyer and seller block, the shipment identifiers (invoice number, date, purchase order, bill of lading), the incoterm and payment terms, every product line (description, HTS code, country of origin, quantity, unit price, weight), freight and insurance and any discount as separate lines, the total value in the transaction currency, and the seller signature. That order matches the 7 step CBP compliant template used by most freight forwarders in 2026.
Is the commercial invoice value FOB or CIF?
Whichever the sales contract states in the incoterm field. FOB means the buyer pays international freight and insurance, so the invoice value excludes them. CIF means the seller pays international freight and insurance, so the invoice value includes them. CBP calculates duty on the FOB equivalent regardless of the incoterm, so under CIF the freight and insurance are deducted out to reach the FOB base.
Conclusion
The commercial invoice is the single most cost sensitive document in an international shipment. Every duty amount, every fee, and every penalty exposure keys on a field the seller wrote (or failed to write) on the invoice. The 14 fields listed above, the incoterm discipline, the HTS classification accuracy, and the country of origin call are what separate a clean 2026 customs cost line from one that racks up back duty, penalty exposure, and holds.
For freight forwarders, modern software OCRs the commercial invoice, matches it against the entry, the packing list, and the bill of lading, and flags every mismatch before the entry is filed. That is where the customs cost line moves. Request a GoFreight demo to see the full commercial invoice to CBP entry workflow inside GoNexus.
