HS Code 3907.29 – Polyethers other than polyacetals, and bis(polyoxyethylene) methylphosphonate; in primary forms

HS code 3907.29 is the 6-digit subheading for polyethers other than polyacetals, and bis(polyoxyethylene) methylphosphonate, in primary forms. It is used for polypropylene glycol (PPG), polyethylene glycol (PEG), polytetramethylene ether glycol (PTMEG), polyether polyols and polyether diols.

What HS 3907.29 covers

This HS code covers a broad category of polyethers in primary forms, excluding polyacetals and the specific bis(polyoxyethylene) methylphosphonate. This diverse group includes various types of polyether polyols, such as polypropylene glycol (PPG), polyethylene glycol (PEG), and polytetramethylene ether glycol (PTMEG), as well as other specialized polyethers. These polymers are fundamental raw materials with a wide array of applications, serving as precursors for polyurethanes (foams, elastomers, coatings), surfactants, lubricants, solvents, and plasticizers. Major importers are typically countries with significant chemical processing industries, particularly those involved in polyurethane production, such as China, Germany, and the USA. Exporters often include nations with large petrochemical industries. The trade in these polyethers is driven by their versatility and critical role in manufacturing everything from flexible foams for furniture to high-performance coatings and personal care products, making them indispensable in modern industry.

Codes often confused with 3907.29

Common mistake. This code is often confused with 390721 (bis(polyoxyethylene) methylphosphonate) if the specific flame retardant polyether is not distinguished, or with 390710 (polyacetals) if the broader "polyether" term is not carefully defined.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
