Air Freight from China to Seoul, South Korea — Transit, Duty and Clearance
China → Seoul · via ICN air / Incheon sea · clearance by Korea Customs Service (관세청)
We move air freight cargo from South China into Seoul through ICN air / Incheon sea. Seoul is capital and the dominant consumer market, which shapes the kind of cargo that moves on this lane and how it should be packed.
The clearing authority is Korea Customs Service (관세청). Historical dwell on this gateway is around 1–3 days, and it lengthens in Sep–Nov.
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.

Duty, tax and clearance into Seoul
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: Seoul checklist
- Ask for the HS code in writing from your supplier and verify the South Korea duty rate against it yourself.
- Confirm the consignee in Seoul 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.
- Use ISPM-15 treated pallets. Untreated wood is the most common reason otherwise-clean cargo gets held.
- Book earlier than the transit time suggests during Sep–Nov, when space on this lane tightens.
- Plan around the China-side windows too: Chinese New Year and Golden Week both compress capacity on the South Korea lane.
Frequently asked questions
How long does shipping from China to Seoul 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 same-day inland leg to Seoul.
What duty and tax will I pay importing into Seoul?
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 Seoul.
Can you deliver door-to-door in Seoul?
Yes. Delivery to a Seoul address is quoted as one figure covering freight, duty and tax owed to Korea Customs Service (관세청), and the same-day inland leg. Confirm whether your consignee wants the goods at a warehouse, a marketplace fulfilment centre 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.
How is the chargeable weight calculated for Seoul?
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 Seoul?
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 same-day inland leg. The crossover point is normally somewhere between 100 and 300 kg depending on the density of your cargo.
