3904.90.00Halogenated EVA Copolymer
Halogenated EVA copolymer, specifically chlorinated ethylene-vinyl acetate, is a polymer in primary form used in adhesive formulations. It is classified under tariff item 3904.90.00 as 'Other' because the copolymer contains halogenated olefin units, but the vinyl acetate comonomer prevents classification under the ethylene polymer headings.
3904.90.00Iodinated Olefin Polymer Powder
Iodinated olefin polymer powder is a specialty polyethylene powder modified with iodine, used in medical imaging contrast agents. It is in primary form (powder) and classified under tariff item 3904.90.00 as 'Other' halogenated olefin polymers, since iodinated polyethylene is not specifically named in any other subheading.
3904.90.00Mixed Halogenated Copolymer Granules
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.
3904.90.00Poly(chlorobrominated) Ethylene
Poly(chlorobrominated) ethylene is a dual-halogenated ethylene polymer used in fire-resistant cables. It is in primary form and classified under tariff item 3904.90.00 as 'Other' halogenated olefin polymers, as the combination of chlorine and bromine does not match any specific subheading for single-halogen polymers.
