Exporting to Korea comes down to four decisions made before the first shipment: who imports the goods and carries the tax, who holds the product certification, which tariff rate the goods qualify for, and in what order those steps run. Duty is set line by line in Korea’s tariff schedule, import VAT is 10 percent, and KC certification, where it applies, must be in place before the product is sold and, for designated items, before it clears customs.
This guide sits under the guide to Korean market entry strategy, whose distributor or agent model has a Korean partner carry sales, support, and often regulatory representation with no Korean entity; this guide covers the import mechanics beneath that model. The statutes cited are the versions published on law.go.kr as of September 2026.
Who Does What When Exporting to Korea?
Three roles decide who controls a Korean export channel: the importer of record, the certification holder, and the distributor. One Korean company can fill all three, which is the arrangement that costs the most to unwind.
The importer of record. Korea’s Customs Act makes the owner of the goods at the time of the import declaration, the hwaju (화주), liable for duty (Article 19), and the declaration is filed in the name of that owner or a licensed customs broker, a gwansesa (관세사) (Article 242). Import VAT on goods imported for a business is creditable against its output VAT (VAT Act Article 38). That is the catch in a delivered duty paid (DDP) quote: it makes the foreign exporter the importer. That importer needs a business customs clearance code (통관고유부호), applied for on the Korea Customs Service’s UNI-PASS portal with a copy of a Korean business registration certificate (clearance code notice No. 2026-21, Article 6). Registered foreign corporations can hold one, even with no Korean address if they appoint a tax administrator (Annex 1, Article 23). An unregistered exporter has neither the code nor output VAT to credit the import VAT against, so quote CIF or DAP and let the Korean buyer clear the goods.
The certification holder. The Electrical Appliances and Household Goods Safety Management Act (전기용품 및 생활용품 안전관리법) places the KC obligation on the manufacturer or the importer, and defines the manufacturer to include a party that manufactures abroad and exports to Korea (Article 5). A foreign manufacturer can therefore hold the certificate in its own name. The Special Act on Children’s Products Safety uses the same definition (Article 17). A certificate the importer files stays with it; the guide to finding a business partner in Korea covers what that means when partners change. For radio and EMC equipment, a holder based abroad must also appoint a domestic agent, whose breaches the Radio Waves Act treats as the holder’s own (Article 58-13), so choose it as carefully as the importer.
The distributor. The distributor buys, resells, and supports the product. Whether it should also import and hold certificates is a structuring choice, covered with the cost of reversing it in the guide to Korea market entry modes.
What Tariffs Apply to Goods Exported to Korea?
Korean duty is set per product line in the tariff schedule annexed to the Customs Act, and the rate depends on the product’s HS classification and its origin.
The WTO’s tariff profile for Korea puts the 2025 simple average most-favoured-nation applied rate at 6.6 percent for non-agricultural products, 57.0 percent for agricultural products, and 13.5 percent overall. Weighted by trade, the overall figure was 8.0 percent. On 2024 import values, 43.3 percent of non-agricultural imports entered duty free under the MFN schedule. Averages set expectations; the only number that prices your product is the rate on its own line.
Classification decides that rate, so settle it before the first price quote. Article 86 of the Customs Act lets the importer or a licensed customs broker ask the Korea Customs Service for an advance ruling on classification before the declaration, and customs applies the ruling when the declared goods match it. Where two plausible lines carry different rates, the ruling is cheap insurance.
Origin can lower the rate further. Korea’s government FTA portal, fta.go.kr, lists agreements in force with the United States, the European Union, the United Kingdom, China, ASEAN, Canada, and Australia, among others. The preferential rate reaches the invoice only when the importer claims it. Under the Act on Special Cases of the Customs Act for the Implementation of Free Trade Agreements, the importer applies before the import declaration is accepted and must hold the proof of origin, submitting it if customs asks (Article 8). A missed claim can be made within one year of acceptance (Article 9). Importers, exporters, and producers keep the origin records for a period of up to five years set by decree, or longer where the agreement requires (Article 15).
That puts a documentary duty on the exporter. If the importer cannot produce the origin evidence when customs asks, customs can decline the preferential rate (Article 8, applying the limits in Article 35) and collect the duty difference from the importer. Your origin file is part of the product your Korean partner is buying.
How Do Customs Value and Import VAT Build the Landed Cost?
Duty is charged on a CIF basis, and import VAT at 10 percent is charged on the duty-inclusive value, so the landed cost stacks in a fixed order.
Article 30 of the Customs Act sets the dutiable value as the price actually paid or payable plus listed additions, including freight, insurance, and other transport costs to the Korean port of import, packing costs borne by the buyer, and royalties and licence fees paid for rights connected to the imported goods. The VAT base on imports is that customs value plus customs duty and any individual consumption, liquor, education, rural development, and transport, energy and environment taxes (VAT Act Article 29). The rate is 10 percent (Article 30), declared and paid to customs together with the duty (Article 50).
An illustration with round numbers: goods with a CIF value of KRW 100 million on a line dutied at 8 percent carry KRW 8 million of duty, and import VAT of 10 percent on KRW 108 million, which is KRW 10.8 million. The importer pays KRW 18.8 million at the border. For a VAT-registered importer the KRW 10.8 million is creditable, a cash-flow item; the KRW 8 million of duty is a cost to everyone.
Two points catch foreign groups. A royalty the Korean buyer pays for a trademark or patent tied to the imported goods can be added to the dutiable value under Article 30, so a licence structure designed for income tax can raise duty. And when your own subsidiary imports, the transfer price is also a customs value. Article 37 lets the importer ask the Korea Customs Service in advance to rule on the valuation method for goods traded between related parties. The income tax side of the same pricing is covered in the guide to Korean corporate tax.
Build the full stack into the landed-price model before quoting, as the guide to validating market demand in Korea recommends. Korean enterprise buyers also settle early whether they book you as an import or a domestic purchase, which decides who bears duty and import VAT; the guide to negotiating with Korean companies covers that fork.
When Does KC Certification Apply?
KC certification applies to product categories designated under Korean safety law, and the category sets the track. Scope comes first, because a product outside the designated lists needs no KC filing under that law.
Under the Electrical Appliances and Household Goods Safety Management Act, three tracks apply by designated category:
- Safety certification (안전인증): the product model is certified against the safety standard and a factory inspection standard (Article 5).
- Safety confirmation (안전확인): each model is tested at a designated laboratory, and the manufacturer or importer files a declaration of conformity (Article 15).
- Supplier’s conformity confirmation (공급자적합성확인): the manufacturer or importer tests the product itself or through a third party and confirms conformity, with a filing required for electrical products (Article 23).
Children’s products follow a parallel structure under their own act, including safety certification with both product and factory inspection (Article 17) and safety confirmation (Article 22). The Korean Agency for Technology and Standards (KATS) administers the KC schemes under both laws.
Radio equipment, and electrical and electronic equipment subject to electromagnetic compatibility requirements, also falls under the Radio Waves Act. Article 58-2 requires conformity assessment for broadcasting and communications equipment through certification, registration, self-confirmation of conformity (added by a January 2024 amendment), or provisional certification, handled through the National Radio Research Agency under the Ministry of Science and ICT. The same amendment added Article 58-13, in force since July 24, 2024: an applicant with no address or office in Korea must designate a domestic agent (국내대리인) in writing to file applications and submit materials. A connected household appliance can need both the electrical safety track and the radio track.
Industrial machinery falls under a separate regime. Under the Occupational Safety and Health Act (산업안전보건법), designated hazardous machinery, equipment, and protective gear need safety certification (Article 84) or a self-confirmation filing (자율안전확인, Article 89), and cannot be made, imported, sold, leased, or used without it (Articles 87 and 92). Both carry the KCs mark. The Korea Occupational Safety and Health Agency (KOSHA) takes the filings and, alongside designated bodies, the certifications (Enforcement Decree Article 116).
Customs checks the paperwork. Article 226 of the Customs Act requires goods that need a permit, approval, or marking under another law to prove it to customs, for items and methods announced in advance, so an uncertified product in a designated category can stop at the border. Other regimes stack beside KC: chemicals under K-REACH, where a foreign manufacturer registers through a Korea-based Only Representative (K-REACH compliance), and food, cosmetics, and medical devices with the Ministry of Food and Drug Safety.
How Does Korean Customs Clearance Work?
The importer, usually through a licensed customs broker, files an import declaration covering the goods’ description, specification, quantity, and price, then pays duty and import VAT. For most goods, customs reviews the tax after release, so a wrong classification, value, or origin claim surfaces as an assessment after the goods have sold.
The statute sets three clocks. Article 241 requires the declaration within 30 days of the goods entering a designated storage area or bonded warehouse, and for goods designated by decree a late declaration draws a penalty of up to 2 percent of the dutiable value. Article 9 sets payment within 15 days of acceptance of the tax declaration. Article 38 has customs review the declared tax after accepting the import declaration, except for categories set by ministerial ordinance.
Small parcels to Korean residents run lighter. Under the Korea Customs Service’s express shipment notice (Article 9), personal-use goods up to USD 150, or USD 200 for shipments under the Korea-US FTA express rule, clear on the courier’s manifest (list clearance, 목록통관) without an import declaration, outside excluded categories. Those priced up to USD 150 before freight are exempt from duty (Customs Act Enforcement Rules Article 45) and, as small consignments to residents, from import VAT (VAT Act Article 27, item 6). The guide to Korean e-commerce platforms covers direct-to-consumer channels.
What Is the Right Order for a First Export to Korea?
Classify first, scope certification second, assign the roles third, then price and ship. Each step constrains the next.
- Classify. Take the product to its Korean tariff line, and request an advance ruling where the line is ambiguous or the rate spread is wide.
- Scope compliance. Check the electrical and household goods lists, the children’s products lists, the radio conformity rules, the Occupational Safety and Health Act machinery lists, K-REACH, and MFDS, and start testing before quoting.
- Assign the roles. Put certificates in your own name where the law allows, and choose the importer of record with VAT recovery and partner control in mind.
- Build the origin file. If an FTA rate applies, assemble proof of origin that your importer can produce on request.
- Model the landed cost. CIF value, duty, import VAT, broker fees, and any royalty addition, against real Korean prices.
- Ship and keep records. File within the 30-day window, pay within 15 days, and keep the origin and valuation records for post-clearance review.
Frequently Asked Questions
Do you need a Korean company to export to Korea? No. A Korean distributor or specialist importer can act as importer of record, file through a licensed customs broker, and credit the import VAT against its own sales. A foreign manufacturer can also hold KC safety certification in its own name. You need your own Korean business registration, through a subsidiary or a branch, when you want to import, invoice, and hold customer relationships directly, or to recover import VAT yourself.
What taxes are due when goods are imported into Korea? Customs duty at the rate for the product’s tariff line, charged on the CIF value, plus 10 percent VAT on the customs value and the duty combined, with individual consumption tax added on some goods. The WTO puts Korea’s 2025 simple average applied duty on non-agricultural goods at 6.6 percent. Duty and VAT are paid within 15 days of acceptance of the tax declaration.
Does a free trade agreement lower Korean duty automatically? No. The importer must apply for the preferential rate before the import declaration is accepted and hold proof of origin, submitting it if customs asks. A missed claim can be filed within one year of acceptance. If the origin evidence cannot be produced, customs can refuse the preferential rate, so the exporter’s origin documentation needs to be ready before the first shipment.
Who should hold the KC certificate for an exported product? The foreign manufacturer, wherever possible. Korea’s electrical and household goods safety law places the duty on the manufacturer or importer and counts a foreign manufacturer exporting to Korea as a manufacturer, so the certificate can sit in your name. A certificate filed by your importer stays with that importer, which ties your product’s legal access to a single partner.
