U.S. imports of diols (other acyclic dihydric alcohols) (HS 290539) totaled $5.3M in June 2026, traded with 23 countries.
Importers of Diols (Other Acyclic Dihydric Alcohols) paid $470K in duties in June 2026 — an effective duty rate of 11% on $4.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Butylene glycol, neopentyl glycol, hexylene glycol, and other acyclic diols not separately enumerated are widely used as polyester polyol building blocks, coatings intermediates, and personal care humectants. Taiwan leads US supply under this heading, followed by Germany and South Korea — a supplier mix that reflects both Asian polymer-chemical export strength and European specialty production. The heading's five 10-digit lines (including 2905391000 for butylene glycol, 2905392000 for neopentyl glycol, and 2905396000 for hexylene glycol) require careful matching of the imported compound to the correct enumerated line before defaulting to the basket provision at 2905399000. Neopentyl glycol in particular is a key raw material for alkyd and polyester resins used in coatings, and supply concentration in Asia warrants attention to lead times.

No. 1,4-Butanediol (BDO) is a distinct chemical with its own classification and is not enumerated under 290539. Butylene glycol at 2905391000 covers the 1,3-isomer commonly used in cosmetics and personal care. Importers must confirm the specific isomer with the supplier's certificate of analysis, as 1,4-BDO is also subject to DEA regulatory controls as a List I chemical precursor, adding a compliance dimension entirely absent for the 1,3-isomer.
Neopentyl glycol production is concentrated among a relatively small number of large Asian and European producers. Capacity outages, feedstock (formaldehyde and isobutyraldehyde) price swings, and shipping disruptions can cause significant price volatility. Buyers relying on neopentyl glycol for coatings or resin production should consider maintaining safety stock and qualifying multiple-origin suppliers to reduce concentration risk.
