What HS code applies to alpha-terpineol?
Alpha-terpineol classifies under HS 2906.19 — cyclic alcohols (cyclanic, cyclenic or cycloterpenic), other. Confirm the destination-country tariff line with your customs broker.
What is the cost of bulk alpha-terpineol?
Bulk pricing depends on grade (fragrance/flavor vs. technical/solvent) and order volume. We supply manufacturers in drums, totes, and IBCs — request a bulk quote with your target grade and tonnage for current pricing, SDS, and CoA.
What is the REACH and TSCA regulatory status of alpha-Terpineol (α-Terpineol)?
alpha-Terpineol (α-Terpineol) (CAS 98-55-5) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006).
