Import Tips & Compliance
• Document the production process and impurity levels to distinguish wet-process acid from other grades, as this affects classification
• Check if the acid is subject to anti-dumping or countervailing duties by reviewing the CBSA's measures in force
• Ensure proper labeling and safety data sheets are provided, as phosphoric acid is a hazardous material under Canadian regulations
