# HS code 2909.19: Acyclic ethers and their halogenated, sulphonated, nitrated or nitrosated derivatives > HS code 2909.19 covers acyclic ethers and their halogenated, sulphonated, nitrated or nitrosated derivatives, other than those classified in 2909.11. It sits in heading 29.09 (ethers, ether-alcohols, ether-phenols, ether-alcohol-phenols, alcohol peroxides, ether peroxides, acetal and hemiacetal peroxides, ketone peroxides (whether or not chemically defined), and their halogenated, sulphonated, nitrated or nitrosated derivatives) in chapter 29 (organic chemicals). Other goods of heading 29.09 are classified under 2909.11 (acyclic ethers and their halogenated, sulphonated, nitrated or nitrosated derivatives, diethyl ether), 2909.20 (cyclanic, cyclenic or cycloterpenic ethers and their halogenated, sulphonated, nitrated or nitrosated derivatives), 2909.30 (aromatic ethers and their halogenated, sulphonated, nitrated or nitrosated derivatives), 2909.41 (ether-alcohols and their halogenated, sulphonated, nitrated or nitrosated derivatives, 2,2'-Oxydiethanol (diethylene glycol, digol)) or 5 others. National tariff lines under 2909.19 are live on border.bot for the United States (4 lines, also used by 1 other country).

Its first two digits, 29, are the chapter; the first four, 2909, are heading 29.09; the last two, 19, identify the subheading within the heading. Countries add their own digits after these six for their national tariff lines. - Chapter 29: Organic chemicals - Heading 29.09: Ethers, ether-alcohols, ether-phenols, ether-alcohol-phenols, alcohol peroxides, ether peroxides, acetal and hemiacetal peroxides, ketone peroxides (whether or not chemically defined), and their halogenated, sulphonated, nitrated or nitrosated derivatives - Within the heading: Acyclic ethers and their halogenated, sulphonated, nitrated or nitrosated derivatives - Subheading 2909.19: Other ## In other countries National tariff lines under 2909.19 are live on border.bot for the United States (4 lines, also used by 1 other country). - [United States](https://border.bot/countries/united-states/hs-codes/290919): 4 lines, used by 1 other country - Previous subheading: [2909.11](https://border.bot/hs-codes/290911) Acyclic ethers and their halogenated, sulphonated, nitrated or nitrosated derivatives: Diethyl ether - Next subheading: [2909.20](https://border.bot/hs-codes/290920) Cyclanic, cyclenic or cycloterpenic ethers and their halogenated, sulphonated, nitrated or nitrosated derivatives ## Frequently asked questions ### What does HS code 2909.19 cover?
