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 for silicone resins containing methacrylate functionality
Silicones with organic modifications classify in Chapter 39 as polymers, not Chapter 29 monomers.
If containing organo-metallic catalyst residues
Organo-inorganic compounds with metal-carbon bonds shift to heading 2931 per Chapter notes.
If sold as ready-to-use adhesive mixture
Chemical preparations for specific use (adhesives) classify in 3824, not pure compounds.

Import Tips & Compliance
• Provide refractive index and boiling point specs matching published values to validate identity
• Include hydroperoxide inhibitor declaration; levels >100ppm may require special handling
• Segregate from strong oxidizers in storage/shipping per NFPA guidelines to prevent polymerization
