HS Code for 2,4,5-T herbicide

2,4,5-T herbicide, specifically 2,4,5-trichlorophenoxyacetic acid, is classified under HS code 2918.91. This classification is based on its chemical structure as a carboxylic acid possessing an additional oxygen function (an ether linkage), which is neither an alcohol, phenol, aldehyde, nor ketone. Chapter 29 of the Harmonized System covers organic chemicals, and heading 2918 is dedicated to carboxylic acids with additional oxygen functions and their derivatives. The subheading 2918.91 precisely identifies "2,4,5-T (ISO) (2,4,5-trichlorophenoxyacetic acid), its salts and esters," ensuring accurate and consistent classification for international trade and regulatory compliance.

Products Included

• 2,4,5-trichlorophenoxyacetic acid (pure chemical)
• Salts of 2,4,5-T (e.g., sodium salt, amine salts)
• Esters of 2,4,5-T (e.g., butyl ester, isooctyl ester)

Common Misclassification

Common misclassifications for 2,4,5-T herbicide often arise from confusion with other phenoxyacetic acid derivatives or with formulated products. It might be confused with 2,4-D (2,4-dichlorophenoxyacetic acid), which is classified under HS code 2918.99 as "other" carboxylic acids with additional oxygen function. Another frequent error is classifying formulated herbicide preparations containing 2,4,5-T under 2918.91; however, such preparations are generally classified under HS code 3808, specifically 3808.93 for herbicides. The distinction is crucial: 2918.91 is for the pure chemical substance and its direct derivatives, while 3808 is for mixtures or preparations.

FAQ

What is the HS code for 2,4,5-T herbicide?

The HS code for the pure chemical substance 2,4,5-T (2,4,5-trichlorophenoxyacetic acid), its salts, and esters, is 2918.91. This code specifically identifies these chemical forms within the category of carboxylic acids with additional oxygen functions.

Is a formulated herbicide containing 2,4,5-T classified under 2918.91?

No, a formulated herbicide preparation containing 2,4,5-T is generally not classified under 2918.91. Formulated herbicide preparations, which are mixtures designed for specific applications, are typically classified under HS code 3808, specifically 3808.93 for herbicides, as they are considered preparations rather than pure chemical substances.
