Import Tips & Compliance
• Submit third-party purity analysis (GC-MS/HPLC) confirming >99.5% MMA content for Chapter 29 classification
• Include end-use statements if electronics-grade; avoid specific-use additives triggering Chapter 29 exclusions
• Package in nitrogen-purged containers; improper packaging may cause polymerization and quality disputes
