Import Tips
• Include GC-MS analysis reports confirming >95% purity of the specific isomer to prevent reclassification as mixtures
• Declare exact CAS number (6776-58-9 if applicable) on commercial invoice for Customs verification
• Watch for stabilizer additions—Chapter note (f) allows them only if necessary for preservation, not specific use
