Certificate of Origin (C/O)

What is Certificate of Origin?

A document certifying where the goods were produced, issued in Korea by a chamber of commerce or by customs. A preferential C/O under a free trade agreement — Korea has FTAs with the EU, the US, ASEAN, China and others — can remove import duty entirely, so request it before shipment rather than after: retroactive claims are possible in some markets but rarely painless.
