A Certificate of Origin (CO) is a one-page document that proves where your goods were made. For most imports from China it is a routine customs form; under a preferential trade agreement it can be the difference between paying the standard MFN tariff and paying zero. Yet importers routinely miss RCEP tariff reductions because they do not know which certificate to request, or their supplier fills it out wrong. This guide explains the two CO types, where to get them, how they affect duty, and the mistakes that get shipments held.
Two Kinds of Certificate of Origin
Not all COs are the same.
- General (non-preferential) CO: simply certifies the country of origin. Required for customs clearance, for some import licenses, and under letters of credit. It does not reduce tariffs.
- Preferential CO: certifies that goods meet the rules of origin of a free-trade agreement, so the buyer can claim reduced or zero import duty. Examples issued for Chinese exports include Form RCEP, Form E (ASEAN-China FTA), Form F (Chile), Form for Australia and Korea under bilateral agreements, and others.
If your destination country has a trade agreement with China and your product qualifies, a preferential CO is free money — a document you should request on every shipment.
RCEP and the Tariff Reduction
The Regional Comprehensive Economic Partnership (RCEP) entered into force on January 1, 2022, covering China, Japan, South Korea, Australia, New Zealand, and the ten ASEAN members. Under RCEP, tariffs on qualifying goods are phased down over time. Public examples are typical: a shipment to Japan saw import duty reduced from 2.5% to 2.2% under RCEP; a Philippines-bound shipment qualified for a reduction from 15% toward zero.
To claim RCEP treatment, the goods must meet the product-specific rules of origin — usually a regional value content threshold or a change in tariff heading. The certificate must be the official Form RCEP, issued or declared by an approved exporter, and presented to the importing customs authority. RCEP certificates can now be self-printed for trade with Japan, Korea, Australia, New Zealand, Singapore, Thailand, Malaysia, Indonesia, and Vietnam.
Who Issues the CO in China
Chinese exporters obtain COs from two channels:
- China Council for the Promotion of International Trade (CCPIT): the traditional issuer for general COs and for many preferential forms. Most forwarders handle this on behalf of the factory.
- General Administration of Customs (GACC): issues preferential certificates and administers the “approved exporter” system. An approved exporter may self-declare origin without waiting for customs review; the approval is valid for three years and must be renewed before expiry.
The application typically requires the commercial invoice, packing list, and a declaration of origin; turnaround is usually one to two working days.
When the Buyer Needs a CO
- Customs clearance: most countries request a CO on file for tariff classification.
- Letters of credit: an LCL clause often requires a specific CO — mismatched wording delays negotiation.
- Quotas or trade restrictions: some countries use COs to track origin for anti-dumping or safeguard measures.
- Preference claims: the importer presents the preferential CO to pay the lower FTA rate.
Common Errors That Hold Shipments Up
- Description mismatch: the goods description on the CO must exactly match the commercial invoice and packing list.
- Late issuance: COs must usually be issued before or at shipment; a post-dated CO can lose preferential treatment.
- Wrong form: using a general CO when an RCEP form is required means the importer pays full duty.
- Rules-of-origin failure: goods assembled in China but made mostly of imported parts may not meet RCEP value-content thresholds; ask your supplier for the calculation.
For repeat orders, ask your supplier to include the CO with the shipping documents every time — not just when you remember to ask.
Electronic COs, Reissuance, and Back-to-Back Certificates
China has largely digitized preferential CO issuance. For RCEP, approved exporters can issue a self-declared origin statement without a paper certificate, and the Chinese customs system supports electronic transmission of CO data to counterpart customs authorities in Japan, Korea, Australia, New Zealand, and ASEAN countries. This speeds clearance and reduces the risk of a paper CO being lost or mismatched.
If a CO is lost or contains an error, it can be reissued — but within the agreement’s time limits, and usually only before the goods clear the importing country. Back-to-back COs are relevant for goods routed through a third RCEP member (for example, consolidated in Singapore before reaching Japan); these require the original CO chain to be preserved. For regular shippers, ask your forwarder to set up an approved-exporter arrangement so future shipments carry the correct preferential documentation automatically, rather than being requested case by case.
One practical tip: at the start of each new product line, ask your customs broker whether the destination country has a FTA with China and whether your HS code is on the concession schedule. Many importers discover years later that they were paying full duty on shipments that qualified for RCEP or ASEAN preferences — money that can never be recovered after customs clearance. A fifteen-minute broker check per HS code at launch prevents that.
