Import Tips
• Ensure the powder is free of soap or other additives that could reclassify it under Chapter 33
• Provide the surface tension test results at 0.5% concentration to confirm surfactant status
• Declare the product as a pure chemical compound if it meets the separate chemically defined criteria, but note Chapter Note 1(b) excludes such compounds—verify purity
