Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2936.29.50Lower: Free vs 40.5%

If further processed into vitamin B1 (thiamine) intermediate

Provitamins and derivatives with alcohol function classify in 2936, later than 2912 per numerical order rule.

2912.19Same rate: 40.5%

If other acyclic aldehydes like pentanal predominate

Other specified acyclic aldehydes beyond butanal isomers fall in 2912.19.90; specific isomer headings take precedence.

3822Lower: 10% vs 40.5%

If imported as laboratory diagnostic reagent preparation

Diagnostic reagents containing this compound classify as lab reagents in 3822, excluding pure Chapter 29 compounds.

Import Tips & Compliance

• Provide pharmacopeia certificates and isomer-specific HPLC chromatograms for CBP verification

• Declare as UN1129 PG II with child-resistant packaging if for pharma end-use to meet FDA import alerts

• Monitor REACH/ TSCA registration; failure to pre-register triggers FDA holds on pharma intermediates

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.

Industrial Grade n-Butanal

Industrial grade n-butanal (normal butyraldehyde) is supplied at 97-99% purity for large-scale production of plasticizers and rubber accelerators. Classified under HTS 2912.19.25.00 as the specific normal isomer of butanal, an acyclic aldehyde without other oxygen functions. Stabilizers may be added solely for preservation per Chapter 29 note (f).

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.
