Import Tips
• Ensure the product is clearly labelled as potassium hydroxide (CAS 1310-58-3) and declare the correct 8-digit code 2815.20.00
• Provide a safety data sheet (SDS) to the CBSA if requested, as potassium hydroxide is a controlled substance under WHMIS
• Verify whether the prills contain any added stabilizers or anti-caking agents, as those may affect classification
