Acetaldehyde
Acetaldehyde (CH3CHO) is a simple acyclic aldehyde used primarily in the production of acetic acid, acetic anhydride, and as a precursor for various chemicals. It falls under HTS 2912.19.5000 as an acyclic aldehyde without other oxygen functions, distinct from formaldehyde, acetaldehyde specified separately, and benzaldehyde. This classification aligns with Chapter 29 notes for separate chemically defined organic compounds.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contaminated or impure formaldehyde content
Formaldehyde takes precedence if present; classified in the heading last in numerical order per Chapter 29 note.
If supplied as a stabilized mixture for specific industrial application
Mixtures with stabilizers for particular use fall outside Chapter 29 scope per note (g), moving to prepared chemical mixtures.
If classified by alcohol precursor rather than aldehyde function
Acyclic alcohols with additional functions may take precedence if dual classification possible, per oxygen function notes.

Import Tips & Compliance
• Provide detailed chemical purity certificates and CAS number (75-07-0) documentation to verify classification as a pure acyclic aldehyde
• Ensure proper Hazard Class 3 (flammable liquid) labeling and UN 2832 shipping papers for safe transport
• Avoid misclassification as mixtures; confirm no added stabilizers render it for specific use per Chapter 29 note (g)
