Air Freight from China to Ulsan, South Korea — Transit, Duty and Clearance
China → Ulsan · via PUS air / Ulsan sea · clearance by Korea Customs Service (관세청)

We move air 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.
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.

| Gateway serving Ulsan | PUS air / Ulsan sea |
| Inland leg to Ulsan | +1 day from the gateway |

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.

What to sort out before the cargo leaves China
- Ask for the HS code in writing from your supplier and verify the South Korea duty rate against it yourself.
- Compare gross weight against volumetric weight (L×W×H ÷ 6000) — the higher figure is what gets billed on air and express.
- Use ISPM-15 treated pallets. Untreated wood is the most common reason otherwise-clean cargo gets held.
- Confirm the consignee in Ulsan can act as importer of record — Korea Customs Service (관세청) will not release cargo to an unregistered party.
- Declare lithium batteries, magnets, liquids and powders up front — retro-declaring after booking usually means re-planning the whole shipment.
- 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 1–3 business 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.
What certification do I need for South Korea?
For regulated goods, plan for: KC certification for electrical and radio products; personal customs clearance code (PCCC) required for every B2C consignee. Missing conformity paperwork is the single most common cause of a hold, and in most cases it cannot be remedied once the cargo has arrived.
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 centimetres 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.
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.
