Import Tips
• Verify against listed name exactly; synonyms like methyl trifluoroacetoacetate must reference CAS 348-58-3 for CBP verification
• Ensure no anti-dusting agents render it specific-use per note (g); standard lab packaging maintains chapter 29 status
• For sets with catalysts, classify individually unless integral per general rules; avoid bulk mixtures
