HS-6 · Subheading
291899
Acids; carboxylic acids, with additional oxygen function (not alcohol, phenol, aldehyde or ketone) and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives; other than 2,4,5-T (ISO)
Heading 2918 — Acids; carboxylic acid with additional oxygen function and their anhydrides, halides, peroxides, peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 291899 when importing or exporting specific organic chemicals that are carboxylic acids with additional oxygen functions. This includes items like certain derivatives that are not classified as alcohols or aldehydes. For example, if you're shipping a specialized chemical used in pharmaceuticals, this code may apply.
This code falls under the broader category of carboxylic acids in the 29 chapter, which includes various organic chemicals. It's important to distinguish this HS-6 from HS-6 2918XX, which covers more specific types of acids with different functional groups.
The HS-6 291899 line specifically covers carboxylic acids and their derivatives that do not fit into more defined categories, such as those specifically excluded like 2,4,5-T. If you have a product that is a halogenated derivative of a carboxylic acid, this is the code to use.
When deciding on this classification, consider the chemical structure and intended use of your product. If your substance has additional oxygen functions but does not fall under the more common classifications, HS-6 291899 is likely the right choice.
