2841.90.30.00/Potassium Stannate Trihydrate/Japan

Potassium Stannate Trihydrate from Japan

Potassium stannate trihydrate (K2SnO3·3H2O) is a white crystalline powder used primarily as a source of stannate ions in chemical plating processes for metals. It falls under HTS 2841.90.30.00 as it is specifically the potassium salt of stannic acid, a peroxometallic acid derivative. This chemically defined inorganic compound is essential for electroless tin plating on substrates like circuit boards.

Import Tips

• Verify purity and hydration state via Certificate of Analysis to match HTS description; ensure MSDS includes hazard classification for DOT compliance

• Common pitfall: mislabeling as general tin compounds leads to reclassification
