Commercial Invoice Explained: What Customs Requires, Who Issues It, and How It Sets Your Duty

By SaveOnShip Editorial Team — Logistics Data Editorial Team. Last updated: 2026-09-01.

Quick answer: A commercial invoice is the primary customs document for an international shipment. Issued by the seller or exporter, it records the description, quantity, value, and origin of the goods, and customs uses it to classify the shipment and calculate the duty and taxes owed. It is not just a bill: the values you declare on it directly set your border bill, and errors or undervaluation cause delays, penalties, or seizure. Yes, you can create your own commercial invoice, and the shipper is responsible for its accuracy.

TL;DR: The commercial invoice is the document customs clears your shipment against. The seller issues it, and its description, value, and origin drive classification and duty. A proforma invoice is a pre-sale quote; only the final commercial invoice is used for entry. With US duty now applying to far more imports, the value you declare matters more than ever. This guide covers what a commercial invoice is, what customs requires on it, how it differs from other invoices, and a worked China-to-USA example.

The commercial invoice works alongside the packing list and, where required, the certificate of origin. For the document that proves where goods were made, see our certificate of origin guide.

What is a commercial invoice, and why does customs require it?

A commercial invoice is the document of the actual sale between the exporter and the importer. Unlike a domestic billing invoice, its primary role in international trade is customs clearance: it tells the border authority what the goods are, how many there are, what they are worth, and where they were made.

Customs requires it because those four facts are how a shipment is assessed. The description and value drive the tariff classification and the dutiable value, and the origin determines which tariffs apply. An inadequate commercial invoice is one of the most common reasons a shipment is held at the border. The US International Trade Administration's commercial invoice page describes it as a required document for the export and import clearance process.

Commercial invoice vs proforma invoice vs regular invoice

Three documents are routinely confused.

• Proforma invoice. A pre-sale document that quotes the buyer an estimated price and terms before the sale is final. It is not used for customs entry.
• Commercial invoice. The final document of the actual sale, issued when the goods ship. This is the one customs clears against.
• Regular (domestic) invoice. A payment request used in domestic trade. It generally lacks the customs-specific fields, such as country of origin and tariff classification, that a cross-border shipment needs.

So the difference between a regular invoice and a commercial invoice is purpose: one requests payment at home, the other clears goods through a foreign border. Only the commercial invoice serves both roles in an international shipment.

Who provides the commercial invoice, and can you create your own?

The seller or exporter provides the commercial invoice, because they are the party to the sale who knows the goods, the price, and the terms. The carrier or freight forwarder does not create it for you, though many provide templates.

Yes, you can create your own commercial invoice. There is no single mandatory global form; what matters is that the document contains the information customs requires and that it is accurate. The responsibility for that accuracy rests with you as the shipper, not with the carrier or the platform that supplied a template. Many exporters generate their own invoice from a template and attach it to the shipment.

What must be on a commercial invoice (customs requirements)

Customs authorities expect certain fields. For US entries, an adequate commercial invoice generally includes:

• Seller and buyer — full names and addresses of both parties.
• Adequate description of the merchandise — what the goods are, in enough detail to classify them.
• Quantities — in the appropriate units, with weights or measures.
• Value — the price actually paid or payable, in the sale currency.
• Country of origin — where the goods were made.
• Incoterm and currency — the delivery term, such as FOB or CIF, and the currency of the transaction.

CBP's guidance on commercial invoice requirements for entry lists these core elements. Missing or vague fields are the top cause of clearance delays.

How the commercial invoice drives your duty and taxes

The commercial invoice is the basis for the duty and taxes you owe. Customs reads the description to assign a tariff classification, applies the duty rate for that classification to the declared value, and uses the stated origin to decide whether additional duties apply. Every line on the invoice feeds the calculation.

This is why accuracy matters and why undervaluation is dangerous. Declaring a lower value than the true transaction value to reduce duty is customs fraud, and it risks penalties, delays, and seizure. The invoice must reflect the real price paid or payable. The duty itself depends on your product's classification and origin, so any estimate is an approximate reference band that requires manual confirmation per shipment. Our harmonized tariff code guide explains how classification sets the rate, and the US customs duty calculator guide shows how the duty is estimated from the invoice value.

A commercial invoice example on a China-to-USA shipment

A quick case study. A US retailer imports 500 units of kitchenware from a Shenzhen supplier on FOB Shenzhen terms for $7,500. The supplier issues a commercial invoice listing the buyer and seller, a clear description of the goods, the quantity of 500 units, the total value of $7,500 in US dollars, China as the country of origin, and the FOB term.

At the US border, customs uses that invoice to classify the kitchenware, applies the applicable duty rate to the $7,500 value, and adds the duties that attach to China-origin goods. Because the supplier described the goods precisely, the shipment clears without a documentation hold. To budget that duty in advance, the retailer would estimate it with a US customs duty calculator and confirm the final figure with CBP. With the de minimis exemption now suspended, even low-value parcels face this calculation, as our guide to the end of de minimis explains.

Common mistakes that delay clearance

The invoice errors that most often hold a shipment:

• Vague descriptions — "parts" or "samples" instead of a specific, classifiable description of the goods.
• Missing or wrong value — omitting the price or stating a value that does not reflect the real transaction.
• Wrong country of origin — declaring the shipping country rather than the manufacturing country.
• Mismatch with other documents — invoice details that do not agree with the packing list or certificate of origin.
• Missing Incoterm or currency — leaving off the delivery term or the currency of sale.

Getting these right the first time keeps the shipment moving. Whatever you declare, confirm shipment-specific document requirements with U.S. Customs and Border Protection or a licensed customs broker before you ship.
