Import Tips & Compliance
• HPLC or GC assay certificates required to prove >95% purity meeting Chapter 29 'chemically defined' criteria
• Anti-dumping documentation may be required if sourced from China due to historical rubber chemical investigations
• Storage stability data prevents reclassification as unstable preparations under 3824
