Washed Kieserite Concentrate from Japan
Washed kieserite concentrate is produced by water washing raw ore to achieve over 95% purity, without drying or heating. Washing is explicitly permitted by chapter note 1 as a process that removes impurities without changing the product's structure, so it remains under tariff item 2530.20.00.

Import Tips
• Keep records showing the concentrate was only washed, not subjected to chemical or thermal processing
• Verify the purity level does not result from crystallization or other excluded processes
• Report the weight excluding water content, as per statistical note 1, to ensure accurate duty calculation
