Import Tips & Compliance
• Ensure the barium sulfate is not mixed with zinc sulfide at import; if co-precipitated, it may be classified as a pigment under Chapter 32
• Declare the exact purity and assay to support classification as a separate chemically defined compound
• Keep certificates of analysis available for CBSA verification
