Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If crude from hydrocarbon oxidation containing >50% aromatics
Chapter 29 excludes crude mixtures from Chapter 27; aromatic hydrocarbon dominance changes classification.
If polymerized to butyraldehyde cyclic trimer
Cyclic polymers of aldehydes specifically exclude from acyclic headings per Chapter note on 2932-2934.
If water-diluted beyond transport safety limits
Aqueous solutions exceeding Chapter 29 note (d) criteria classify as mixtures of Chapter 38.

Import Tips & Compliance
• Include distillation logs showing iso-butanal <0.5% to substantiate normal isomer classification
• Use stainless steel IBCs (Intermediate Bulk Containers) rated for corrosive aldehydes per UN specifications
• Pre-clear TSCA certification to avoid EPA import notifications for new chemical substances

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).
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.
