Import Tips
• Label shipments with exact CAS number (123-66-0 equivalent structure) and batch purity to match the specific HTS subheading
• Avoid common pitfall of declaring as 'antioxidant mixture' which shifts to 3824; specify as pure compound
• Comply with REACH/TSCA registration proofs for polymer additives entering US markets
