Import Tips & Compliance
• Ensure the grains are accompanied by a certificate of analysis confirming purity and particle size distribution, as CBSA may verify the sieve test
• Classify as semi-manufactured iridium, not powder, to avoid misclassification
• Consider whether the grains are for investment casting, which may require additional end-use documentation
