From the buying desk

Fertilizer grade (about 60% K2O) and industrial or food grades are separate products; customs classification also changes with the grade. Much of the potash traded in China is imported, so check where the product really originates. Not dangerous goods.

Import Card

Before you order potassium chloride from China, see its register listing, the duty, anti dumping cases and a supplier check on one card, each with its source and date.
