How to Issue a Certificate of Origin: Authority vs Self-Issuance

Key takeaways

• A non-preferential certificate of origin, which carries no duty benefit, is issued by the Korea Chamber of Commerce and Industry.
• To claim an FTA preferential rate you need the document the agreement specifies: authority-issued (e.g. China, Vietnam, ASEAN, India, RCEP) or self-certified (e.g. US, EU, UK, Canada).
• Authority-issued certificates are normally applied for before shipment, with the export declaration, invoice or contract and an origin statement attached.

A certificate of origin states where goods come from. For Korean exports it splits in two. A non-preferential certificate, issued through the Korea Chamber of Commerce and Industry origin center, answers a buyer or foreign customs request to show Korean origin. An FTA document is different: it is what the importer needs to claim a preferential rate, and only the form named in that agreement works. A general chamber certificate does not unlock an FTA rate by itself.

Preferential and non-preferential proofs do different jobs

Non-preferential proofs are used for ordinary clearance, tender rules, and trade-remedy questions. Preferential proofs exist to claim the treaty rate. Korea Customs Service describes two issuing methods. Authority issuance means customs or another authorized body checks origin and issues the certificate. Self-issuance means the exporter or producer prepares and signs the document under the agreement’s rules. The official overview is on the Korea Customs Service FTA portal.

The agreement picks the method

Authority issuance is the route for Korea–China, Korea–Viet Nam, Korea–ASEAN, Korea–Singapore, Korea–India, and RCEP (where approved exporters may also self-certify). In Korea the counters are customs and the chamber. Applications go through UNI-PASS or the KCCI certificate of origin center.

Self-issuance, often as a certificate or as an origin statement on the invoice, is the route for Korea–US, Korea–EU, Korea–UK, Korea–EFTA, and Korea–Canada. On Korea–EU and Korea–UK shipments, only an approved exporter may make an origin declaration when the consignment exceeds 6,000 euros. Approval is permission to certify, not a customs ruling that the goods are Korean. The origin determination stays with the company.

Type	Document	Who issues it in Korea	Typical agreements
Non-preferential	General certificate of origin	Korea Chamber of Commerce and Industry	Not tied to an FTA rate
Authority-issued	FTA certificate of origin	Customs or the chamber	China, Viet Nam, ASEAN, India, RCEP
Self-issued	Certificate or invoice statement	Exporter or producer, if eligible	United States, EU, UK, Canada

Download the current form from the portal’s certificate-of-origin templates. A buyer’s old file often has outdated box numbers.

Authority issuance is built around pre-shipment filing

Under the enforcement rule of the Act on Special Cases of the Customs Act for FTA Implementation, an applicant files the issuance request with supporting papers before shipment is complete. Korea Customs Service’s English guidance lists a copy of the export declaration, the invoice or export contract, and an origin statement or an accepted substitute. Some agreements allow a post-shipment filing within a set window. Check that window on the portal for the agreement you are using rather than assuming a single deadline.

The working sequence is short. Confirm the 10-digit HS code and the concession rate, test the product against the agreement’s rule of origin, then match description, quantity, and value to the export declaration, invoice, and packing list. File with customs or the chamber. If the producer and the exporter are different, an origin confirmation from the producer is required. A first-time applicant with no domestic plant, or one who does not make the goods, can be selected for an on-site check. An approved exporter may be excused from that check.

Chamber filings for export documents also need user registration, a registered signature, and a business or trade accredited certificate. A bank-only certificate is not accepted.

A worked example of the duty gap

Rates move by product, agreement, and date. This is only the arithmetic. Look up the live rate on the customs tariff portal before you quote a saving.

Assume an invoice of 10,000 US dollars, an applied most-favored-nation rate of 8 percent, and an FTA rate of 0 percent, with the invoice used as a simplified customs value. Duty at the general rate is 10,000 × 0.08 = 800 dollars. Duty at the FTA rate is 0. The 800-dollar gap is the certificate’s tariff value in this example. Import VAT is often charged on a base that includes duty, so the cash difference can be larger than 800 dollars. If the goods fail the rule of origin, the gap is zero.

Mistakes that get the claim refused

The usual rejection is the wrong agreement: a self-issued invoice statement on a China shipment that requires an authority certificate, or a form for a different agreement than the one the importer plans to claim. For Viet Nam, where both Korea–Viet Nam and Korea–ASEAN apply, agree with the buyer on which one to use first. Descriptions that do not match the export declaration, a 6-digit code where the importer needs a national line, and a post-shipment certificate with a blank invoice number are close behind. On agreements that require an approved-exporter number, leaving that number off is enough for the importing customs authority to deny the preference.

Summary

Use the chamber for a general origin certificate. For an FTA rate, follow that agreement: authority issuance or self-issuance, not both at random. Authority filings are due before shipment, with the export declaration, invoice, and origin statement as the core set. Korea–EU and Korea–UK declarations above 6,000 euros require approved-exporter status. Price the saving only after you have checked the rate.

FAQ

Does a general certificate of origin give the FTA preferential rate?

No. A non-preferential certificate only shows that goods are Korean; the preferential rate needs the certificate or origin declaration required by the specific FTA.

What is the difference between authority-issued and self-certified origin?

With authority issuance, customs or the chamber checks origin and issues the certificate. With self-certification, the exporter or producer completes and signs the declaration under the agreement’s rules.

When is approved-exporter status needed under the Korea–EU and Korea–UK FTAs?

For consignments over EUR 6,000, only an approved exporter may make out the origin declaration.

Why do preferential claims get refused?

Common causes are using the form for the wrong agreement, product descriptions that differ from the export declaration, and six-digit HS codes that clash with the importing country’s classification.
