Chloroprene Rubber (CR) from Mexico
Chloroprene rubber, also known as neoprene, is an elastomeric synthetic polymer derived from chloroprene monomer, classified under HTS 3904.90.1000 as an elastomeric polymer of halogenated olefins. It is produced in primary forms such as bales or pellets for further processing into seals, gaskets, and wetsuits. The high chlorine content in its structure qualifies it as a halogenated olefin polymer meeting the 95% monomer weight requirement.

Import Tips
• Verify monomer composition via supplier certificates to confirm 95%+ chloroprene content for elastomeric classification
• Ensure documentation specifies 'primary form' (e.g
• bales, not finished products) to avoid reclassification under Chapter 40
