Korean Buyers: Import or Make in Thailand? (2026)
Korean companies often use Thailand as a second source alongside China, or as an ASEAN production base for regional sales. Both goals change the answer: a hedge wants flexibility, a production base wants tooling and a long contract.
Which model fits your objective?
| Objective | Recommended model |
|---|---|
| Reduce China concentration risk | Dual source: import Thai stock in parallel first |
| Cost reduction on a mature SKU | Contract manufacture with own tooling |
| ASEAN market entry | Manufacture in Thailand, sell regionally, avoid re-import |
If your aim is a China hedge, qualify the Thai plant on a live SKU before moving tooling — see second-source qualification.
Duty and origin
AKFTA and RCEP both cover Thailand–Korea trade, and the preferential rate depends on which agreement your HS code and origin evidence favour. You need a valid certificate of origin under the chosen agreement, and the factory must be able to demonstrate the qualifying rule — details in the AKFTA and RCEP duty guide.
Compliance before tooling
- KC mark for electrical, electronic and children's products
- K-REACH registration or notification for chemical substances
- MFDS approval for food, health functional food, cosmetics and devices
- Korean labelling: importer details, origin, safety information in Korean
- Metrology and packaging rules for retail-facing goods
Freight and lead time
Laem Chabang to Busan is roughly 8–12 days, one of the fastest lanes from Thailand, which makes Thai sourcing far more responsive than transpacific alternatives and reduces the safety stock penalty of a second source.
Break-even in practice
Tooling and certification at USD 30,000 with a USD 2.20/unit saving breaks even near 13,600 units. Short transit lets you reach that faster with lower inventory than a distant source would allow. Use the break-even model.
FAQ
Should I claim AKFTA or RCEP preference?
Compare the preferential rate and the origin rule for your HS code under each agreement, then choose the one your factory can actually satisfy with documentation.
Does the KC mark apply to industrial parts?
It applies mainly to regulated electrical, electronic and consumer safety categories. Confirm your product category before tooling, since design changes may be needed.
Is Thailand cheaper than Chinese suppliers?
Not always on unit price. The gain is usually risk diversification, tariff exposure and short transit to Busan rather than the lowest quotation.
How fast can we get a second source running?
Plan three to four months for qualification on an existing spec, six months where new tooling and KC certification are required.
Can we manufacture in Thailand for ASEAN sales only?
Yes, and it avoids Korean import steps entirely. Structure invoicing and origin documentation for the destination markets you actually serve.
