Sea Freight from China to Ulsan

China → Ulsan · via PUS air / Ulsan sea · clearance by Korea Customs Service (관세청)

Sea Freight from China to Ulsan, South Korea — cargo handling at the departure terminal
Shipping from China to Ulsan.

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.

Routing and transit on this lane

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.

Duty, tax and clearance into 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.

Pre-shipment checklist for Ulsan

  • Check the de-minimis position (USD 150) against your invoice value before you decide how to split the shipment.
  • Compare gross weight against volumetric weight (L×W×H ÷ 6000) — the higher figure is what gets billed on air and express.
  • Plan around the China-side windows too: Chinese New Year and Golden Week both compress capacity on the South Korea lane.
  • Ask for the HS code in writing from your supplier and verify the South Korea duty rate against it yourself.
  • Put the Ulsan delivery address, contact name and phone number on the invoice, not just the packing list.
  • Declare lithium batteries, magnets, liquids and powders up front — retro-declaring after booking usually means re-planning the whole shipment.

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.

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.

How is the chargeable weight calculated for Ulsan?

We compare actual gross weight against volumetric weight — length × width × height in centimeters divided by 6000 for air — and bill the greater of the two, rounded up to the next kilogram. Light, bulky cargo is almost always billed on volume.

References & official sources

Duty rates, thresholds and conformity requirements for South Korea change by ministerial decision, sometimes mid-year. The figures on this page are buyer-planning references, not a customs ruling — confirm the current position for your own HS code with Korea Customs Service (관세청) or your broker before you ship.

Shipping by industry

This page covers the route and clearance picture for the destination. Packing, classification and the compliance step that actually holds a shipment depend on what you are sending — these guides cover that by commodity.

Checking the South Korea duty position yourself

We publish these figures so you can budget, but the assessment that binds is the one Korea Customs Service makes on your declaration. Where a shipment is large enough that a percentage point matters, check their current tariff guidance rather than ours.

Classification drives everything downstream: the same carton can attract very different duty depending on the heading it lands in, and the structure those headings come from is the World Customs Organization Harmonized System. If your product sits near a boundary between two headings, resolve it before shipping rather than at the border.

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.

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.

Why these three decide everything

They determine whether your cargo can fly, and on which service. A declared battery changes the price; an undeclared one grounds the shipment at the airport and you pay storage while it sits. Unauthorized brands are seized at customs and the freight is lost with them. Magnetic goods need a field test — routine, but it has to be booked ahead. Telling us now costs a click; telling us later costs the shipment.
