Last updated: August 2026 dataAcetals and hemiacetals are oxygen-containing organic intermediates widely used as fragrance fixatives, flavoring agents, pharmaceutical synthesis building blocks, and polymer stabilizers. India and China together account for the bulk of US import supply under this heading, with Switzerland and Germany representing higher-value specialty chemical sources. The US schedule distinguishes 1,1-bis-(1-methylethoxy)cyclohexane (2911001000) — a specific cyclic acetal used in fragrance applications — from the broader NESOI basket (2911005000), making precise chemical identification important at entry.

Carving out a specific compound into its own 10-digit line (2911001000) typically reflects meaningful trade volume or a distinct duty treatment relative to the NESOI basket. For fragrance and flavor manufacturers, correct classification of this cyclic acetal ensures accurate duty assessment and avoids misclassification penalties.
Acetals intended for use as food flavoring agents may be subject to FDA review under GRAS (Generally Recognized as Safe) determinations or food additive regulations, in addition to standard customs entry. Importers should confirm the intended end-use and consult both a licensed customs broker and applicable FDA guidance before importing flavoring-grade acetals.
