Import Tips
• Provide flake composition analysis showing anti-caking agent doesn't alter primary chemical function
• Ensure flake form doesn't constitute 'put up for retail sale' which might invoke Chapter 38
• Declare exact water content; excessive dilution could shift to Chapter 29 note (d) aqueous solutions
