Import Tips
• Include SDS and COA specifying dihydrate form (CAS 10049-04-4); mismatch causes valuation disputes
• For water treatment use, obtain TSCA certification; pitfall is classifying cleaning blends under 3402 instead
• Declare phosphate content accurately to avoid anti-dumping scrutiny on Chinese origins
