HS Code 2917.37 – Acids; aromatic polycarboxylic acids; dimethyl terephthalate

HS code 2917.37 is the 6-digit subheading for acids, aromatic polycarboxylic acids, dimethyl terephthalate. It is used for dimethyl terephthalate flakes, DMT for PET, DMT for polyester fibers, DMT for specialty polyesters and DMT for films.

What HS 2917.37 covers

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.

Codes often confused with 2917.37

Common mistake. 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.

Top exporters and importers of HS code 291737, 2025

In 2025, the largest exporter of HS code 291737 in UN Comtrade data was South Korea, with 60% of world exports; the largest importer in UN Comtrade data was Luxembourg, with 23% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
