Industrial Grade Potassium Hydroxide 90% Flakes
Potassium hydroxide in flake form with 90% purity, used primarily in soap manufacturing and as a strong alkali in chemical synthesis. The flakes are a solid form of potassium hydroxide, and the 90% purity does not preclude classification under tariff item 2815.20.00, which covers potassium hydroxide with or without impurities.

Import Tips & Compliance
• Declare the flakes under 2815.20.00, and note that the 90% purity is acceptable under the tariff item as long as the balance is water or harmless impurities
• The CBSA may request a certificate of analysis to confirm the composition
• Ensure the flakes are packaged in moisture-proof containers, as they are hygroscopic
