Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported in bulk for industrial synthesis rather than as named compound
Other cyclic aldehydes fall under the broader 2912.29.25 subheading if not specifically listed in 2912.29.30.
If dissolved in solvent for safe transport
Chapter 29 note (e) allows solutions in solvents for safety/transport to stay in Chapter 29; otherwise, diagnostic reagents in 3822.
If used primarily as synthetic fragrance ingredient
Chapter 29 excludes coloring matter or odoriferous substances of heading 3202 if put up for specific use.

Import Tips & Compliance
• Provide Certificate of Analysis (CoA) confirming chemical identity and purity as 3,4-Dimethylbenzaldehyde to match HTS specification
• Include Safety Data Sheet (SDS) detailing hazards, handling, and transport conditions for aldehyde compounds
• Avoid misclassification as fragrance compounds; verify no additional oxygen functions beyond the aldehyde group
