Shipping from China to Ulsan

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

Freight forwarding from China to Ulsan, South Korea — container and air cargo handling
Cargo handling on the China–Ulsan lane.

We move freight cargo from South China into Ulsan through PUS air / Ulsan sea. Ulsan is shipbuilding, automotive and petrochemical base, which shapes the kind of cargo that moves on this lane and how it should be packed.

Clearance itself is handled by Korea Customs Service (관세청), and typical dwell at the gateway runs 1–3 days.

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.

Import duty and tax position for Ulsan

Imports into South Korea are cleared by Korea Customs Service (관세청). The headline position is: VAT 10%; duty 8% general rate, with reductions under the China–Korea FTA on a valid certificate of origin. The de-minimis threshold is 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

  • 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.
  • Photograph carton markings and seal numbers before departure — it makes any claim far easier to settle.
  • 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.
  • 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 1–3 business days by air, 2–5 calendar days by sea. 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.

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.

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.

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.

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.

Answer these and you get a real price, not a range. These are the exact figures a carrier needs before it will quote. Fill them in once and we can price your cargo the same day — leave them out and we have to come back and ask, which is what turns an hour into a week.

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. Unauthorised 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.
