Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If methyl methacrylate instead of ethyl
Different alcohol chain length changes specific ester classification within same methacrylic acid heading.
If contains >20% reaction catalysts/solvents
Catalyst-containing reaction mixtures classify as Chapter 38 organic composites, not pure monomers.
If ether impurities exceed 2%
Significant ether content shifts classification to Chapter 29 ether-alcohol compounds.

Import Tips & Compliance
• 1
• Declare exact stabilizer type/concentration on commercial invoice; 2
• Temperature-controlled shipping (<40°C) required to prevent polymerization; 3
• Avoid wooden packaging - use stainless steel or HDPE containers only
