Sea Freight from China to Ulsan, South Korea — Transit, Duty and Clearance
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.
How this lane actually runs
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.

What you will pay on arrival in South Korea
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.

Before you book: Ulsan checklist
- Check the de-minimis position (USD 150) against your invoice value before you decide how to split the shipment.
- Get the conformity paperwork moving early: KC certification for electrical and radio products; personal customs clearance code (PCCC) required for every B2C consignee.
- Ask for the HS code in writing from your supplier and verify the South Korea duty rate against it yourself.
- Declare lithium batteries, magnets, liquids and powders up front — retro-declaring after booking usually means re-planning the whole shipment.
- Compare gross weight against volumetric weight (L×W×H ÷ 6000) — the higher figure is what gets billed on air and express.
- Put the Ulsan delivery address, contact name and phone number on the invoice, not just the packing list.
