Import Tips & Compliance
• Include GMP or USP certificate to support pharma end-use and prevent scrutiny under general chemical headings
• Label with exact CAS number and batch purity to match HTS specific naming requirements
• Pre-register under TSCA if new importer; pharma intermediates often trigger EPA review
