Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-mixed with initiators for retail dental kits
Finished dental preparations classify under Chapter 30 pharmaceutical products, not bulk chemicals.
If acrylic acid ester instead of methacrylic
Absence of methyl group on acid changes from methacrylic to acrylic acid ester subheading.
If diluted >30% with dental solvents
Solvent solutions exceeding Chapter 29 note (e) limits classify as Chapter 38 chemical mixtures.

Import Tips & Compliance
• 1
• Include GC-MS purity certificate (≥99.5%) and nitrogen headspace verification; 2
• Separate from food/medical shipments due to monomer toxicity; 3
• FDA cosmetic notification may apply for dental use
