Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as methanal (formaldehyde) derivative
Specific acyclic aldehydes like formaldehyde have priority headings; numerical order rule applies per chapter notes.
If containing heterocyclic oxygen ring structures
Chapter notes exclude cyclic oxygen heterocyclic compounds from aldehyde headings, moving to specific heterocyclic provisions.
If put up in diagnostic kits with biologicals
Immunological products containing aldehydes classify under Chapter 30 per chapter exclusion (e).

Import Tips & Compliance
• Require NIST-traceable certificates of analysis specifying ACS compliance and Lot# traceability
• Ship in amber glass bottles ≤1L with child-resistant caps for lab quantities to meet hazmat exemptions
• Declare exact CAS# 78-84-2; misdeclaration risks penalty and reclassification to generic mixtures
