HS Code Subheading

Acids; carboxylic acids, with additional oxygen function (not alcohol, phenol, aldehyde or ketone) and their anhydrides, halides, peroxides and peroxyacids; 2,4,5-T (ISO) (2,4,5-trichlorophenoxyacetic acid), its salts and esters

About HS Code 291891

This specific HS code is dedicated to 2,4,5-T (ISO), also known as 2,4,5-trichlorophenoxyacetic acid, and its salts and esters. Historically, 2,4,5-T was a widely used synthetic auxin herbicide for defoliation and controlling woody plants and broadleaf weeds, particularly in agriculture and forestry. Its trade primarily involved agricultural chemical companies and government agencies in the past. However, due to severe environmental and health concerns, notably its association with dioxin contamination, the use of 2,4,5-T has been severely restricted or completely banned in most countries globally. Consequently, current international trade is minimal, highly regulated, and typically limited to research purposes or specific, controlled applications where still permitted under strict conditions.

Products Under This Code

2,4,5-T acid, 2,4,5-T sodium salt, 2,4,5-T esters (e.g., butyl ester), 2,4,5-T formulations (historical)

Real World Examples

Dow Chemical (historical producer), Monsanto (historical producer), generic agrochemical companies (historical)

Common Misclassification

Could be confused with other phenoxy-herbicides like 2,4-D (2918.99 or 3808) if the specific trichloro- structure is not noted, or with general herbicides in Chapter 38.
