About HS Code 291737

Dimethyl terephthalate (DMT) is an ester primarily used in the production of polyethylene terephthalate (PET) resin and polyester fibers. While purified terephthalic acid (PTA) has largely replaced DMT in new PET plants due to process efficiencies, DMT still holds importance in older facilities and for specific specialty polyester applications. Countries with established textile industries and older PET production facilities are key importers, often in regions like Southeast Asia and parts of Europe. Exporters are typically chemical manufacturers with integrated petrochemical complexes. Trade considerations include its solid flake form, purity specifications, and competition with PTA. Its demand is linked to the global textile and packaging sectors, though its market share has diminished over time, making it a more niche product in modern trade.

Products Under This Code

Dimethyl terephthalate flakes, DMT for PET, DMT for polyester fibers, DMT for specialty polyesters, DMT for films, DMT for engineering plastics

Real World Examples

Eastman DMT, Mitsubishi Chemical DMT, Sinopec DMT, Reliance Industries DMT, Indorama Ventures DMT

Common Misclassification

Often confused with 291736 (terephthalic acid and its salts) as it's a derivative, or with 291734 (other esters of orthophthalic acids) if the specific "dimethyl terephthalate" identity is not clearly stated.
