Import Tips
• Declare the solution as potassium hydroxide under 2815.20.00, and note that the semiconductor end-use does not alter classification unless the solution is doped or contains other chemicals
• The CBSA may ask for a certificate of analysis to confirm purity
• Ensure the solution is not classified as a hazardous waste if it contains impurities
