Import Tips & Compliance
• Potassium nitrate may be subject to import controls as an oxidizer; verify with the CBSA whether a permit is required under the Explosives Act
• Ensure the product is pure KNO3 without stabilizers or anti-caking agents that could change its classification
• If imported for fertilizer use, confirm whether it falls under Chapter 31 instead of Chapter 28
