Sea Freight from China to Ulsan
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.
Clearance itself is handled by Korea Customs Service (관세청), and typical dwell at the gateway runs 1–3 days.
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.
| Sea gateways used | Busan, Incheon, Gwangyang |
|---|---|
| Sea transit, China to gateway | 2–5 calendar days |
| Gateway serving Ulsan | PUS air / Ulsan sea |
| Inland leg to Ulsan | +1 day from the gateway |
| Typical clearance / dwell | 1–3 days |
| Peak season to plan around | 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.

Before you book: Ulsan checklist
- Budget for the inland leg: +1 day beyond gateway clearance to reach Ulsan.
- Use ISPM-15 treated pallets. Untreated wood is the most common reason otherwise-clean cargo gets held.
- Compare gross weight against volumetric weight (L×W×H ÷ 6000) — the higher figure is what gets billed on air and express.
- Declare lithium batteries, magnets, liquids and powders up front — retro-declaring after booking usually means re-planning the whole shipment.
- Photograph carton markings and seal numbers before departure — it makes any claim far easier to settle.
- Get the conformity paperwork moving early: KC certification for electrical and radio products; personal customs clearance code (PCCC) required for every B2C consignee.
Frequently asked questions
How long does shipping from China to Ulsan take?
China to the South Korea gateway is 2–5 calendar days. On top of that, allow 1–3 days of clearance with Korea Customs Service (관세청) and a +1 day inland leg to Ulsan.
What duty and tax will I pay importing into Ulsan?
Korea Customs Service (관세청) applies: VAT 10%; duty 8% general rate, with reductions under the China–Korea FTA on a valid certificate of origin. The de-minimis position is USD 150. Under a DDP arrangement these are pre-paid, so nothing is collected on arrival in Ulsan.
Can you deliver door-to-door in Ulsan?
Yes. Delivery to a Ulsan address is quoted as one figure covering freight, duty and tax owed to Korea Customs Service (관세청), and the +1 day inland leg. Confirm whether your consignee wants the goods at a warehouse, a marketplace fulfillment center or a shop front, because the last-mile requirement differs.
What documents does Korea Customs Service (관세청) require?
A commercial invoice with HS codes, a packing list, the bill of lading or air waybill, a certificate of origin where it lowers duty, and any product certification (KC certification for electrical and radio products; personal customs clearance code (PCCC) required for every B2C consignee). We prepare and file these as part of the service.
When is the busiest time on the China–South Korea lane?
Space and rates tighten around Sep–Nov, plus the China-side windows of Chinese New Year in January or February and Golden Week in early October. Book one to two weeks earlier in those periods.
Is sea freight cheaper than air freight into Ulsan?
Per kilo, yes — usually by a wide margin. The trade-off is time: 2–5 calendar days by sea versus 1–3 business days by air to the South Korea gateway, before clearance and the +1 day inland leg. The crossover point is normally somewhere between 100 and 300 kg depending on the density of your cargo.

Checking the South Korea duty position yourself
Treat the landed-cost numbers here as a planning baseline. Korea Customs Service sets the rate that actually gets charged, assessed against your HS classification at the moment of clearance, so their own guidance is worth reading before a large order.
If you want to sanity-check a duty figure yourself, start from the heading rather than the product name — the WCO Harmonized System is the underlying nomenclature, and the WTO Tariff & Trade Data portal holds the applied rates by country pair.
For ocean cargo, restricted commodities move under the IMO's IMDG Code, and the container has to be declared and stowed accordingly. Batteries, flammables and corrosives all have a compliant ocean path; what causes rolled bookings is finding out about them after the container is packed.
On the origin side, export declaration and any commodity inspection requirement fall under China Customs (GACC); we handle that filing as part of the service, but the requirement is theirs, not ours.
If this is your first shipment into South Korea, the South Korea Country Commercial Guide covers the practical import environment in more depth than a rate page reasonably can, and it is written by a party with no stake in your booking.
