Heading 2917 — Acids; polycarboxylic acids, their anhydrides, halides, peroxides and peroxy-acids; their halogenated, sulphonated, nitrated or nitrosated derivatives
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 291737 when importing or exporting dimethyl terephthalate (DMT), a key ingredient in polyester production. For instance, a shipment of DMT in bulk containers for textile manufacturing would fall under this code.
This code is specific to aromatic polycarboxylic acids, which includes DMT, distinguishing it from other polycarboxylic acids like terephthalic acid (HS-6 291736). While both are used in polyester production, DMT's unique chemical structure makes it suitable for certain applications.
When classifying under HS-4 2917, note that it encompasses a variety of acids and their derivatives. This means you might encounter similar codes for other aromatic acids, but they will differ based on their specific chemical properties and applications.
Understanding the nuances of HS-6 291737 is crucial for compliance. Ensure your product descriptions clearly state the chemical composition and intended use to avoid misclassification and potential customs issues.
