Korea Export Procedures and Documents, Explained

Key takeaways

• The export declaration is filed through UNI-PASS in the name of the Korean cargo owner, a licensed customs broker or the manufacturer that supplied the goods (Customs Act Article 242). In practice, a foreign buyer without a Korean business is not the exporter of record.
• Accepted goods must be loaded within 30 days. Customs can extend this by up to one year (Customs Act Article 251).
• The export declaration certificate (수출신고필증) is the exporter's proof of export and the basis for 0% VAT. Korea's standard VAT rate is 10%.
• A Korean exporting agent can buy from domestic suppliers without VAT, because sales to an exporter under a purchase confirmation (구매확인서) or local L/C are also zero-rated.
• Every shipment needs a commercial invoice, packing list and bill of lading or air waybill. Add proof of origin to claim an FTA rate, and an SDS, test reports or a UN 38.3 summary when the product requires them.
• For quality checks, AQL sampling now follows ISO 2859-1:2026, which replaced the 1999 edition on 22 January 2026.

How does export clearance work in Korea?

Export clearance means declaring the goods to Korea Customs Service (KCS), getting the declaration accepted and loading the goods onto a ship or aircraft. Everything is filed electronically through UNI-PASS, the KCS clearance system, usually by a licensed customs broker working for the exporter.

1. Contract and goods ready. The sale is agreed, the goods are produced and packed, and the loading schedule is fixed with the forwarder.
2. Declaration filed. The exporter or its broker files the export declaration through UNI-PASS with the HS code (the product's customs classification number), quantity, value and buyer details. It goes to the customs office responsible for the place where the goods are stored, which can be the factory or a warehouse rather than the port.
3. Risk screening. The KCS cargo-selectivity system sends each declaration down one of three paths: automatic acceptance, document review or physical inspection of the cargo.
4. Acceptance. Once the declaration is accepted, the export declaration certificate is issued electronically with an acceptance number.
5. Loading and departure. The goods are trucked to the port or airport and loaded within the legal deadline.

For complete, low-risk declarations, acceptance usually comes the same day. A document review or an inspection takes longer.

Who files the export declaration?

The Korean side does. Under Article 242 of the Customs Act, a declaration must be made in the name of the cargo owner or a licensed customs broker. For exports it may also be made in the name of the manufacturer that supplied the goods.

The declaration must carry the declarant's customs unique code (통관고유부호), and KCS issues that code only to businesses registered with Korea's National Tax Service. The overseas buyer appears on the declaration under a separate overseas buyer code.

This is why EXW (ex works) terms rarely suit purchases from Korea: they make the buyer responsible for an export declaration it cannot file itself. It is also why small suppliers that sell only in Korea often export through an agent. They may have no customs code, no English export documents and no experience with the VAT paperwork described below.

How soon must goods be loaded after clearance?

Within 30 days of the declaration being accepted. Under Article 251 of the Customs Act, customs can extend the loading period by up to one year, and if the goods are not loaded in time, it can cancel the acceptance.

The declaration must be accepted before loading. The law sets no fixed number of hours before departure; in practice the carrier's or forwarder's cut-off decides. KOTRA's process chart puts the declaration after the loading schedule is fixed and before the goods are trucked to the port.

What is the export declaration certificate, and how does VAT work?

The export declaration certificate (수출신고필증) is the official record that customs accepted the export declaration. It is issued electronically through UNI-PASS with an acceptance number and is the exporter's main proof that the goods were exported as declared. The exporter uses it:

• as the basis for charging 0% VAT on the export sale;
• to claim back customs duty paid on imported materials used in the goods (duty drawback);
• to obtain certificates of origin under the ASEAN, Singapore, India, China and Vietnam agreements, which require a copy unless the exporter has approved-exporter status.

Korea's standard VAT rate is 10%, and exports are zero-rated under Article 21 of the VAT Act. The same article also zero-rates goods sold within Korea to an exporter under a local letter of credit (L/C) or a purchase confirmation (구매확인서). This is how a Korean exporting agent can buy from a domestic-only supplier without paying VAT and then ship the goods to you. If the goods are simply delivered to an address in Korea, the sale is domestic and VAT normally applies.

Which documents does a shipment from Korea need?

Every commercial shipment needs a commercial invoice, a packing list and a transport document, and most also need proof of origin. Other documents depend on the product and the destination.

Your destination market decides which product certificates you need, such as cosmetics notifications or electronics conformity marks. Our K-beauty import guide covers the cosmetics rules, and the shipping guide explains dangerous goods rules for batteries and perfume.

How do you get a certificate of origin from Korea?

It depends on the trade agreement your customs authority will apply. Some agreements need a certificate issued by an authority in Korea; others let the exporter, producer or (for the US) the importer certify origin.

By law, the issuing body must issue a certificate within 3 days of the application, or 10 days if it needs an on-site check, not counting weekends and public holidays. KCS grants approved-exporter status, which is valid for five years. Our FTA guide explains rules of origin and how to claim the lower rate.

Should you inspect goods before they leave Korea?

Yes, for any order you could not easily replace. A pre-shipment inspection is usually done when at least 80% of the order is finished, before you pay the balance and before the goods are loaded. The inspector checks a random sample for:

• quantities finished and packed;
• workmanship, colours and construction against the approved sample;
• artwork, labels and functional tests;
• dimensions and unit weights;
• inner and outer packing, carton sizes and weights, and shipping marks, which should match the packing list.

Sample sizes and pass/fail limits usually follow AQL (acceptance quality limit) tables. The international standard for them was revised this year: ISO 2859-1:1999 was withdrawn on 22 January 2026 and replaced by ISO 2859-1:2026. Inspectors in the US often use the equivalent ANSI/ASQ Z1.4 tables. A common choice for consumer goods is 0 critical, 2.5 major and 4.0 minor at General Inspection Level II, but the limits are yours to set in the purchase order.

Which mistakes most often delay export shipments?

Most delays come from paperwork, not from customs itself. These are the problems to rule out before the goods leave the factory:

• Documents that do not match. The invoice, packing list, carton marks and declaration show different quantities, weights or descriptions.
• No Korean exporter of record. EXW terms, or a supplier without a customs code, leave nobody able to file the declaration.
• Declaring at the wrong customs office. The declaration belongs with the office responsible for where the goods are stored; filing elsewhere can be punished as a false declaration.
• Missing the loading deadline. Goods not loaded within 30 days of acceptance, without an extension, can have the acceptance cancelled.
• Wrong HS codes or undervalued invoices. They cause holds and penalties and can cost you the FTA rate at destination. Always declare the real price.
• Missing or invalid origin proof. For example, an EU or UK origin declaration above €6,000 from an exporter without approved-exporter status. Without valid proof, you pay the full duty rate.
• Undeclared dangerous goods. Lithium-ion batteries shipped alone or packed with equipment above 30% state of charge by air, or perfume booked as general cargo, will be refused or held.

What happens when the goods arrive?

Your customs broker files the import declaration using the commercial invoice, packing list, transport document and proof of origin. Duty depends on the HS code, the country of origin and the customs value, and in most countries import VAT or sales tax is added.

Import rules have changed quickly. The US no longer exempts low-value parcels, the EU charges a €3 duty per item on parcels up to €150, and US duty on Korean goods has changed several times since 2025. Check the current position in our trade agreements guide, and confirm the rate for your HS code with a licensed customs broker before you price the goods. If you pay by letter of credit, the documents above must also comply with the terms of the credit; see our payment guide.
