How to Read a Commercial Invoice for Customs

The commercial invoice is the primary document used to determine the customs value of imported goods. Customs authorities worldwide rely on it to compute duty, identify the parties, verify origin, and assess regulatory compliance. A well-prepared commercial invoice makes entry smooth; a sloppy one triggers requests for additional information, inspections, holds, and in extreme cases penalties.

This guide explains the required data elements, the common errors, and how to extract the right information for a clean customs entry.

Required data elements

For US imports, 19 CFR 141.86 specifies the minimum content of a commercial invoice:

  1. Names and addresses of the shipper and consignee.
  2. Time, place, and country of the sale.
  3. Detailed description of the merchandise:
    • Quality, kind, grade.
    • Marks, numbers, symbols.
    • Marks of identification.
  4. Quantities by weights and measures.
  5. Purchase price of each item in the currency of the purchase.
  6. Currency used.
  7. Other charges: discounts, commissions, packing costs.
  8. Country of origin of the goods.
  9. Itemized statement of all goods or services for which payment is made:
    • Any rebates, drawbacks, bounties.
  10. Signature of the seller, manufacturer, or authorized representative.

These are the regulatory minimums. In practice, customs brokers also need the HS code (10-digit HTSUS for the US, 8-digit CN for the EU), the shipper's tax identifier, the consignee's EIN or VAT, and freight/insurance breakdown.

Common errors

1. Vague descriptions

"Electronic components" is not sufficient. "1,000 units of Bluetooth headphones, model BH-200, over-ear, in retail packaging, HTS 8518.30.20" is sufficient.

The description must let customs identify the goods. Vague descriptions trigger document requests, inspections, and delays.

2. Missing HTS code

Not legally required on the invoice but practically essential. The broker needs it to file the entry; if omitted the broker must classify or query the shipper, delaying clearance.

3. Missing country of origin

Origin is required. Without it the entry cannot be filed. Default-of-shipper-country is the wrong assumption; goods shipped from China can be of Korean origin if substantially transformed in Korea before re-export.

4. Wrong Incoterms

Stating "FOB" without naming the port creates ambiguity. Always: "FOB Shanghai" or "CIF Newark" specifying the named place.

5. Currency confusion

State the currency. "25.00" without currency designator is ambiguous between USD, EUR, CNY. Use the ISO 4217 code (USD, EUR, CNY, INR, JPY).

6. Pricing discrepancies

The invoice price must match the transaction value: the price actually paid or payable for the goods. Discounts, commissions, royalties, and assists may need to be added back to derive the dutiable value. Hidden adjustments invite 1592 penalties.

7. Missing shipper signature

US customs requires the invoice to be signed by an authorized representative of the seller. Unsigned invoices can be rejected.

8. Mismatched line items

The invoice quantities must match the packing list and the bill of lading. Discrepancies trigger holds while customs investigates.

9. Wrong unit of measure

State unit of measure clearly: "pieces" vs "pairs" vs "sets" vs "kg". For HTS lines that require statistical reporting in specific units (kg, m, dozen), the invoice must support the required unit.

10. Royalties or assists not declared

Royalties paid to the seller as a condition of sale must be added to the dutiable value. Assists (parts, tools, dies provided by the buyer to the seller for use in producing the goods) must be added at their value plus transportation.

Special considerations

Related-party transactions

When buyer and seller are related (parent-subsidiary, common ownership), customs scrutinizes whether the price reflects an arm's length transaction. Documentation supporting the price (transfer pricing study, comparable uncontrolled price analysis) should be ready.

Multiple invoices for one shipment

For commercial reasons (legal entity routing), multiple invoices may cover one physical shipment. Customs prefers one invoice; if multiple are unavoidable, the broker must consolidate the data for the entry.

Pro forma invoices

A pro forma invoice (preliminary, before payment) is not a commercial invoice and is not acceptable for customs entry. Customs needs the final, signed commercial invoice.

DDP shipments

Under DDP, the seller pays duty and VAT. The commercial invoice must clearly show:

  • The product value.
  • The freight and insurance separately if shown to the buyer.
  • A note: "DDP terms; seller pays import duty and VAT."

How to use a commercial invoice for landed cost

For landed cost calculation:

  1. Extract the transaction value (price actually paid).
  2. Identify any additions required for dutiable value: assists, royalties, packing, selling commissions not included.
  3. Identify the terms of sale: FOB, CIF, etc.
  4. Separately note freight and insurance if not in the price.
  5. Apply the destination country's customs value rule (FOB-based for US, CIF-based for EU/UK).
  6. Identify the country of origin (not shipping origin).
  7. Identify the HS code at the destination country's specificity (10-digit for US).
  8. Compute duty per the calculation rules for that origin-destination-HTS combination.

How the calculator extracts from invoices

The LandedFees calculator accepts PDF and image uploads of commercial invoices. The AI extracts:

  • Shipper and consignee.
  • Line items with descriptions, quantities, prices.
  • HTS codes (or proposes them if missing).
  • Country of origin.
  • Terms of sale.
  • Currency.
  • Freight and insurance breakdowns.

You can review and correct the extracted data before computing the landed cost. The output is itemized per line with the full duty stack.

Frequently asked questions

Is a commercial invoice the same as a sales invoice?

Often yes for the same transaction, but customs has specific data requirements. A sales invoice that lacks HS codes, country of origin, or shipper details is incomplete for customs purposes.

What is the minimum content required?

Per 19 CFR 141.86: shipper and consignee, description of merchandise, quantities, prices, currency, country of origin, weight, terms of sale (Incoterms), and signature of the seller's representative.

Does the commercial invoice need to be in English?

For US customs, yes. A translation must accompany any foreign-language invoice. Some authorities accept invoices in their official languages plus translations.

Can a single invoice cover multiple shipments?

Generally no for customs purposes. Each entry needs its own commercial invoice tied to one consignment.

What happens if the invoice value is wrong?

Undervaluation triggers 19 USC 1592 penalties up to four times the lost duty. Overvaluation has no duty consequence but creates other issues (tax shifting, transfer pricing). Always declare the true transaction value.
