Import Tips
• Keep certificates of analysis showing impurity levels, as customs may verify the 'optical grade' claim against Chapter 29's purity standards
• The product must not contain additives that render it suitable for a specific use beyond general monomer purposes
• Consider applying for a ruling from the CBSA if you regularly import this grade, to avoid classification disputes
