Certificate of Origin
A document certifying the country where goods were manufactured, used to claim preferential duty rates and satisfy import requirements.
DocumentationTL;DR: This term is one of 28 definitions in the China–GCC freight glossary, so the signal is the number it changes — not the acronym.

What it means
A Certificate of Origin (CO) is a document that certifies the country in which the goods were produced. It is issued by a chamber of commerce or authorised body in the exporting country, and it matters in two ways. First, it proves origin for compliance — some GCC imports require a CO as a matter of course. Second, and more valuably, a preferential CO (under a free-trade agreement) can reduce or eliminate import duty. For China-to-GCC trade the base GCC tariff of 5% applies by default, and China currently has no broad FTA with the GCC, so most COs here are non-preferential proof-of-origin documents rather than duty-savers. Still, a CO is frequently requested by GCC customs, especially for re-exports and for goods subject to anti-dumping or origin-specific rules, so it is cheap insurance to obtain one with each shipment.
Why it matters on the China–GCC route
A Certificate of Origin proves where your goods were made and is frequently required by GCC customs — obtain it with each shipment even when no preferential rate applies.
Example
A Kuwaiti importer attaches a Chamber of Commerce Certificate of Origin to a Shenzhen shipment of machinery, satisfying Kuwait Customs origin requirements for the entry.
