HS Code for Ethylene polymers

Ethylene polymers in primary forms that do not fall under more specific subheadings are classified under HS code 3901.90. This code serves as a residual or "basket" category within Heading 3901, which covers all polymers of ethylene in primary forms. According to Note 6 to Chapter 39, "primary forms" refers to liquids, pastes, dispersions, solutions, blocks of irregular shape, lumps, powders, granules, and flakes. Classification in 3901.90 is required when the polymer does not meet the criteria for polyethylene with a specific gravity of less than 0.94 (3901.10), polyethylene with a specific gravity of 0.94 or more (3901.20), ethylene-vinyl acetate copolymers (3901.30), or ethylene-alpha-olefin copolymers (3901.40). This often includes specialty ethylene-based resins, chemically modified polyethylenes, or copolymers where ethylene is the predominant monomer but the specific gravity or the nature of the comonomer does not trigger the other specific subheadings. Accurate classification requires detailed technical specifications regarding the polymer's density and monomeric composition.

Products Included

• Specialty ethylene copolymers not elsewhere specified
• Chemically modified polyethylene in primary forms
• Ethylene-propylene copolymers where ethylene predominates
• Liquid ethylene polymers and dispersions

Common Misclassification

A frequent error is misclassifying these products under 3901.10 or 3901.20. These codes are strictly for polyethylene homopolymers or copolymers that meet specific density requirements. If the product is a copolymer with an alpha-olefin, it must go to 3901.40. Another common mistake is using 3902.10 if the product contains propylene; however, if ethylene is the predominant monomer by weight, it must remain in 3901 per Note 4 to Chapter 39. Finally, finished plastic articles are often wrongly classified here, but 3901.90 is strictly for primary forms.

FAQ

What is the HS code for Ethylene polymers?

The general HS code for ethylene polymers in primary forms not specified elsewhere is 3901.90.

How do I distinguish between 3901.10 and 3901.90?

3901.10 is specifically for polyethylene with a specific gravity of less than 0.94. If the polymer is a specialty blend or a modified version that doesn't fit the standard polyethylene definition, it falls under 3901.90.
