Import Tips
• Label with CAS number (if assigned) and purity percentage; customs often rejects vague chemical descriptions
• Obtain end-use statement for non-pharma applications to prevent dual-use scrutiny
• Avoid bulk packaging over 25kg without stabilizer, as chapter note (f) requires for pure compounds
