From the buying desk
Commercial stearic acid is a blend of stearic and palmitic acids, and grades are named by the split, such as 1801 or 1842. Most Chinese supply is made from imported palm oil, so ask about RSPO certification if your customers need it. Not dangerous goods; customs classification depends on purity.
Import Card
Before you order stearic acid from China, see its register listing, the duty, anti dumping cases and a supplier check on one card, each with its source and date.
