Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemically converted to paraformaldehyde derivative
Cyclic polymers of aldehydes classify under 2912.60, excluding simple acyclic aldehydes like butanal.
If primarily ethyl alcohol content with butyraldehyde impurity
Chapter 29 excludes ethyl alcohol (2207/2208); alcohol-dominant mixtures classify as alcohols in 2905.
If esterified with acetic acid forming butyl acetate
Esters of acyclic alcohols with acyclic carboxylic acids classify in 2915 per Chapter 29 ester classification note (A).

Import Tips & Compliance
• Submit GC-MS analysis reports distinguishing normal from iso-butyraldehyde to confirm 2912.19.25.00 classification
• Include stabilizer composition details; additions must not render product suitable for specific end-use per Chapter 29(g)
• Verify bulk packaging meets UN-approved 1H1 drums for Class 3 flammable liquids to avoid customs delays

Normal Butyraldehyde 99% Pure
Normal butyraldehyde (butanal), the straight-chain isomer, is a colorless volatile liquid used primarily as an intermediate in chemical synthesis for pharmaceuticals and fragrances. It falls under HTS 2912.19.25.00 as an acyclic aldehyde without other oxygen functions, specifically the normal isomer of butanal. This chemically defined organic compound meets Chapter 29 note (a) for separate organic compounds.
Pharma-Grade Butyraldehyde
Pharmaceutical-grade butyraldehyde (normal butanal) meets USP/EP standards for synthesis of active pharmaceutical ingredients like vitamins. It is the chemically defined normal isomer under HTS 2912.19.25.00, acyclic aldehyde without other oxygen function. Low impurity levels ensure compliance with Chapter 29 purity requirements.
Butanal with 0.1% Hydroquinone Stabilizer
Normal butanal stabilized with 0.1% hydroquinone to prevent polymerization during storage and transport. Remains classified as pure butanal under HTS 2912.19.25.00 since stabilizer is necessary for preservation per Chapter 29 note (f). Used in flavor/fragrance synthesis.
Distilled n-Butyraldehyde 98.5%
High-purity distilled n-butyraldehyde at 98.5% concentration, fractionally distilled to remove iso-butanal impurities. Specifically the normal isomer under HTS 2912.19.25.00 as acyclic aldehyde without other oxygen function. Essential for high-value polymer precursor synthesis.
