Its first two digits, 29, are the chapter; the first four, 2912, are heading 29.12; the last two, 11, identify the subheading within the heading. Countries add their own digits after these six for their national tariff lines. - Chapter 29: Organic chemicals - Heading 29.12: Aldehydes, whether or not with other oxygen function; cyclic polymers of aldehydes; paraformaldehyde - Within the heading: Acyclic aldehydes without other oxygen function - Subheading 2912.11: Methanal (formaldehyde) ## In other countries No national tariff lines under 2912.11 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 2912.11 at six digits and add their own digits after it. - Previous subheading: [2911.00](https://staging.border.bot/hs-codes/291100) Acetals and hemiacetals, whether or not with other oxygen function, and their halogenated, sulphonated, nitrated or nitrosated derivatives - Next subheading: [2912.12](https://staging.border.bot/hs-codes/291212) Acyclic aldehydes without other oxygen function: Ethanal (acetaldehyde) ## Frequently asked questions ### What does HS code 2912.11 cover?
