Mixed Halogenated Copolymer Granules from Mexico
Mixed halogenated copolymer granules contain chlorine, fluorine, and bromine in a single copolymer, used for specialty coatings requiring multi-halogen properties. These granules are in primary form and classified under tariff item 3904.90.00 as 'Other' because no single halogenated monomer unit predominates sufficiently to fall under a more specific subheading.

Import Tips
• Provide a detailed monomer composition analysis to the CBSA, showing the weight percentages of chlorine, fluorine, and bromine monomers
• If no single monomer predominates, classification under 3904.90.00 is appropriate, but if one halogenated monomer exceeds 95%, a more specific subheading may apply
• Ensure the granules are not further worked beyond primary form, as this could reclassify the product
