HS Code 2905.41 – Alcohols; polyhydric, 2-ethyl-2- (hydroxymethyl) propane-1,3-diol (trimethylolpropane)
HS code 2905.41 is the 6-digit subheading for alcohols, polyhydric, 2-ethyl-2- (hydroxymethyl) propane-1,3-diol (trimethylolpropane). It is used for trimethylolpropane (TMP), TMP triacrylate, TMP trimethacrylate, TMP diallyl ether and TMP ethoxylate.
What HS 2905.41 covers
Trimethylolpropane (TMP) is a vital polyhydric alcohol extensively traded globally, primarily valued for its three hydroxyl groups which make it an excellent building block for various polymers and resins. Its international trade is driven by demand from the coatings, adhesives, sealants, elastomers, and synthetic lubricants industries. Major chemical producers and distributors are key exporters, while countries with robust manufacturing sectors for paints, automotive components, and industrial coatings are significant importers. Key aspects for traders include understanding its different grades (e.g., technical grade, low-VOC grade) and their specific applications. The stability of raw material supply, particularly formaldehyde and butyraldehyde, can influence TMP prices and availability. Its role in enhancing durability, flexibility, and chemical resistance in end products makes it a sought-after ingredient, with demand often linked to industrial growth and construction activity.

Codes often confused with 2905.41
Common mistake. This code specifically covers trimethylolpropane; it should not be confused with other polyhydric alcohols like pentaerythritol (290542) or glycerol (290545), which have different chemical structures and applications. Misclassification might occur if the specific "trimethylolpropane" identity is not confirmed.
Top exporters and importers of HS code 290541, 2025
In 2025, the largest exporter of HS code 290541 in UN Comtrade data was China, with 83% of world exports; the largest importer in UN Comtrade data was the United States, with 23% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
