Certificate of Origin

A Certificate of Origin (CO) is a trade document that certifies the country in which goods were wholly produced, manufactured, or substantially transformed. Customs authorities use it to determine the applicable tariff rate, enforce trade agreements, and apply trade restrictions such as anti-dumping duties, quotas, and import bans. For exporters, the CO is often required to qualify for preferential duty rates under free trade agreements.

Why Country of Origin Matters

The "origin" of goods is not simply where they were shipped from — it's where they were made. A product assembled in Vietnam from Chinese components might have Vietnamese origin if sufficient transformation occurred. A product merely repackaged in Mexico and shipped to the US is not of Mexican origin.

Origin matters because:

• Tariff rates: FTAs like USMCA, EU-Korea, and CPTPP grant preferential (reduced or zero) duty rates for qualifying goods
• Anti-dumping and countervailing duties: ADD/CVD orders target specific countries. Chinese steel subject to 200% ADD does not become non-Chinese by transshipment through a third country.
• Sanctions and import restrictions: Certain countries are subject to import bans or restrictions requiring origin verification
• Trade statistics: Governments track trade flows by origin for policy purposes

Types of Certificates of Origin

Non-Preferential CO: A general document certifying origin without claiming FTA benefits. Required by many importing countries as standard documentation. Usually issued by a Chamber of Commerce.

Preferential CO: Issued under a specific FTA to claim reduced duty rates. Different FTAs use different forms:

• GSP Form A: For developing country exports to countries offering Generalized System of Preferences
• EUR.1 Movement Certificate: For EU trade agreements
• USMCA Certificate of Origin: For USMCA (replacing NAFTA's NAFTA Certificate)
• Form E: ASEAN-China FTA
• REX (Registered Exporter): EU's self-certification system replacing physical CO documents for some programs

Rules of Origin

Each FTA defines its own Rules of Origin (RoO) — the criteria a product must meet to qualify for preferential treatment. Common criteria:

• Wholly obtained: Products entirely grown, harvested, or extracted in one country (agricultural commodities, minerals)
• Substantial transformation: The product was transformed into a different tariff classification, or underwent specific manufacturing processes
• Regional value content (RVC): A minimum percentage of the product's value must originate within the FTA region

A product may qualify for preferential origin under one FTA but not another, because different FTAs have different rules. This complexity is one reason many exporters work with customs brokers or trade compliance specialists to manage FTA utilization.

Issuing Bodies

In most countries, Chambers of Commerce issue standard COs. Specialized government agencies issue preferential COs. In the US, CO verification for specific programs (GSP, USMCA) can involve CBP Form 28 (Request for Information) or CF-29 (Notice of Action) during import examination.
