Import Tips
• Provide detailed chemical analysis (NMR, GC-MS) confirming aromatic substitution on propionic chain to avoid reclassification
• Declare purity level and CAS number (6771-56-2); stabilizers must not change general use per Chapter 29 note (g)
• Ensure SDS and REACH compliance for EU transshipments; common pitfall is mislabeling as non-aromatic ester
