More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If polymerized into polymethyl methacrylate (PMMA)
Polymerized forms exceed monomer stage and classify as acrylic polymers in Chapter 39, not Chapter 29 organic compounds.
If specifically of a type listed in statistical suffix
More specific 10-digit suffixes exist for certain methacrylate esters; 'other' applies only when not matching primary categories.
If mixed with >2% other substances for specific formulation
Mixtures not qualifying as pure Chapter 29 compounds fall to prepared chemical mixtures in Chapter 38.

Import Tips & Compliance
• Verify purity levels and provide certificate of analysis (COA) to confirm classification as chemically defined compound per Chapter 29 notes
• Ensure proper hazardous material documentation (UN 1247) for transport as flammable liquid; include stabilizer content details
• Avoid misclassification as polymer by confirming <99% polymerization; test samples if bulk shipments vary
