HS-4 · Heading
2912 — Aldehydes, whether or not with other oxygen function; cyclic polymers of aldehydes; paraformaldehyde
Chapter 29: Organic chemicals
Plain-language overview
Use HS-4 2912 when importing aldehydes like formaldehyde or acetaldehyde, which are commonly used in chemical manufacturing and food processing. For example, if you're shipping methanal (formaldehyde) in bulk for industrial use, this is the correct code.
When deciding between HS-6 lines, note that 291211 covers methanal (formaldehyde) specifically, while 291212 is for ethanal (acetaldehyde). If your product doesn't fit these two, check 291219 for other acyclic aldehydes without additional oxygen functions.
For cyclic aldehydes, 291221 is designated for benzaldehyde, while 291229 includes other cyclic aldehydes. Ensure you identify the specific compound to select the right subheading.
If your shipment includes aldehyde derivatives like vanillin or ethylvanillin, you’ll look at 291241 and 291242 respectively. Use 291249 for other aldehyde-ethers or phenols that don’t fall under these specific categories.
