HS Code for Polyether

Polyethers in primary forms are classified under HS code 3907.29. Chapter 39 of the Harmonized System covers plastics and articles thereof, with the first sub-chapter focusing on primary forms such as liquids, pastes, blocks, or granules. Heading 3907 includes polyacetals, other polyethers, and epoxide resins. The classification of a specific polyether depends on its chemical structure. While polyacetals are specifically called out in 3907.10, other polyethers fall into the 3907.2x category. Subheading 3907.29 is a residual category for "other" polyethers that do not meet the specific definitions of polyacetals or bis(polyoxyethylene) methylphosphonate. This classification requires the product to be in a primary form; once the polyether is converted into a finished article, such as a pipe or sheet, it moves to the respective headings for those articles. The term "primary forms" is strictly defined in Note 6 to Chapter 39, ensuring that only raw materials are captured here.

Products Included

• Polyethylene glycol (PEG) in primary forms
• Polypropylene glycol (PPG) in liquid or paste form
• Polytetramethylene ether glycol (PTMEG)
• Other polyethers used as chemical intermediates

Common Misclassification

Polyethers are often misclassified under HS code 3907.10 if they are mistaken for polyacetals. They may also be confused with HS code 3824.99, which covers miscellaneous chemical products, but if the product is a polymer in primary form, Chapter 39 takes precedence. Additionally, if the polyether is an epoxide resin, it must be classified under 3907.30.

FAQ

What is the HS code for polyethers?

The HS code for polyethers (other than polyacetals) in primary forms is 3907.29.

Does this code include finished plastic parts?

No, this code only applies to primary forms like liquids or granules. Finished parts are classified by their shape or function in other headings of Chapter 39.
