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

We move sea freight cargo from South China into Incheon through ICN air / Incheon sea. Incheon is port and airport city with the shortest inland leg, which shapes the kind of cargo that moves on this lane and how it should be packed.
On the destination side, Korea Customs Service (관세청) handles clearance; budget 1–3 days of dwell before the cargo is released.
Import duty and tax position for Incheon
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.
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.

Pre-shipment checklist for Incheon
- Confirm the consignee in Incheon can act as importer of record — Korea Customs Service (관세청) will not release cargo to an unregistered party.
- Photograph carton markings and seal numbers before departure — it makes any claim far easier to settle.
- Book earlier than the transit time suggests during Sep–Nov, when space on this lane tightens.
- 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.
- Ask for the HS code in writing from your supplier and verify the South Korea duty rate against it yourself.
Frequently asked questions
How long does shipping from China to Incheon 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 same-day inland leg to Incheon.
What duty and tax will I pay importing into Incheon?
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 Incheon.
Which port or airport does cargo for Incheon clear through?
Cargo for Incheon is routed via ICN air / Incheon sea. Sea gateways for South Korea are Busan, Incheon, Gwangyang; air gateways are ICN (Incheon), PUS (Busan Gimhae). We pick whichever gives the shortest total door time for your address.
Can you ship batteries or sensitive cargo to Incheon?
Yes. Battery cargo by sea moves under UN3480/UN3481 with an MSDS, and the dangerous-goods documentation is prepared as part of the booking into Busan, Incheon, Gwangyang. Surcharges apply and space is more limited than for general cargo.
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 Incheon?
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.
