HS Code for Halogenated polyolefin

Halogenated polyolefins are classified under HS code 3904.90 because they are polymers of halogenated olefins that do not fall under the more specific subheadings of heading 3904. Heading 3904 generally covers polymers of vinyl chloride or of other halogenated olefins, in primary forms. While subheadings 3904.10 through 3904.69 cover specific substances like poly(vinyl chloride) and fluoro-polymers like PTFE, the 3904.90 code serves as a residual category for \"other\" halogenated olefin polymers. This classification is determined by the chemical structure of the polymer, specifically the presence of halogen atoms (fluorine, chlorine, bromine, or iodine) attached to the olefinic backbone. According to the General Rules of Interpretation (GRI) 1 and 6, the product must be in a primary form, such as liquids, pastes, blocks, or powders, to remain within this chapter. If the polyolefin has been further processed into a finished article, it would move to headings 3917 through 3926. The technical nature of these polymers, often used for specialized coatings or chemical-resistant components, requires precise chemical analysis to confirm the absence of non-halogenated monomers that might shift the classification to heading 3901 or 3902.

Products Included

• Chlorinated polyethylene in primary forms
• Chlorosulfonated polyethylene
• Polyvinylidene fluoride (PVDF) not elsewhere specified
• Brominated polyolefins
• Fluorinated ethylene-propylene (FEP) in primary forms

Common Misclassification

These products are frequently confused with non-halogenated polyolefins under heading 3901 (polyethylene) or 3902 (polypropylene). The presence of even a small amount of halogen atoms necessitates a move to 3904. Additionally, specific fluoro-polymers like PTFE are classified under 3904.61, and should not be placed in the residual 3904.90 category if they meet the specific purity and structural requirements of the earlier subheadings.

FAQ

What is the HS code for halogenated polyolefin?

The HS code for halogenated polyolefins in primary forms, not elsewhere specified, is 3904.90.

How does 3904.90 differ from 3904.10?

HS code 3904.10 is strictly for poly(vinyl chloride) not mixed with any other substances, whereas 3904.90 is a residual category for other halogenated olefin polymers that do not meet the definitions of the preceding subheadings.
