Its first two digits, 29, are the chapter; the first four, 2905, are heading 29.05; the last two, 31, identify the subheading within the heading. Countries add their own digits after these six for their national tariff lines. - Chapter 29: Organic chemicals - Heading 29.05: Acyclic alcohols and their halogenated, sulphonated, nitrated or nitrosated derivatives - Within the heading: Diols - Subheading 2905.31: Ethylene glycol (ethanediol) ## In other countries No national tariff lines under 2905.31 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 2905.31 at six digits and add their own digits after it. - Previous subheading: [2905.29](https://staging.border.bot/hs-codes/290529) Unsaturated monohydric alcohols: Other - Next subheading: [2905.32](https://staging.border.bot/hs-codes/290532) Diols: Propylene glycol (propane-1,2-diol) ## Frequently asked questions ### What does HS code 2905.31 cover?
