Shipping from China to Ulsan, South Korea — Freight Guide [2026]
China → Ulsan · via PUS air / Ulsan sea · clearance by Korea Customs Service (관세청)
Ulsan is shipbuilding, automotive and petrochemical base, and it is served through PUS air / Ulsan sea. That combination is what actually sets your delivery date on this lane — allow +1 day for the inland leg on top of clearance.
The clearing authority is Korea Customs Service (관세청). Historical dwell on this gateway is around 1–3 days, and it lengthens in Sep–Nov.
Import duty and tax position for Ulsan
Korea Customs Service (관세청) assesses duty and tax on cargo arriving for Ulsan consignees. Current regime: VAT 10%; duty 8% general rate, with reductions under the China–Korea FTA on a valid certificate of origin, with a de-minimis position of USD 150.
Conformity is the part most first-time importers underestimate: KC certification for electrical and radio products; personal customs clearance code (PCCC) required for every B2C consignee. Getting this wrong is expensive because it usually cannot be fixed after the cargo has landed.
Restrictions and known friction points for South Korea: Every B2C shipment needs the consignee's PCCC — missing codes are the single largest cause of held parcels. KC certification is mandatory for electricals. Food and cosmetics require MFDS clearance held by a local importer.
What the routing looks like in practice
Korea is the shortest sea lane from North China — Qingdao or Weihai to Incheon can be 2–3 days, and the sea-air combination via Incheon is a well-established cost saver for cargo continuing to Europe or the Americas. The China–Korea FTA cuts duty on a large share of manufactured goods if the origin certificate is prepared correctly.

Before you book: Ulsan checklist
- Ask for the HS code in writing from your supplier and verify the South Korea duty rate against it yourself.
- Book earlier than the transit time suggests during Sep–Nov, when space on this lane tightens.
- Confirm the consignee in Ulsan can act as importer of record — Korea Customs Service (관세청) will not release cargo to an unregistered party.
- Plan around the China-side windows too: Chinese New Year and Golden Week both compress capacity on the South Korea lane.
- Compare gross weight against volumetric weight (L×W×H ÷ 6000) — the higher figure is what gets billed on air and express.
- Budget for the inland leg: +1 day beyond gateway clearance to reach Ulsan.
