Heading 2917Acids; 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 291736 when importing or exporting terephthalic acid, a key ingredient in the production of polyester fibers and resins. For example, a shipment of 1,000 kg of terephthalic acid in 25 kg bags would fall under this code.

This code specifically covers aromatic polycarboxylic acids, particularly terephthalic acid, which is distinct from other acids like isophthalic acid (HS-6 291735). While both are used in similar applications, they have different chemical structures and properties.

When classifying products, it's important to differentiate between terephthalic acid and its derivatives. For instance, if you're dealing with dimethyl terephthalate (DMT), you would need to look at a different HS code under the same heading.

Terephthalic acid is often found in various forms, such as granules or powder, and is primarily used in textiles and plastics. Understanding the specific application can help in determining the correct classification and any applicable tariffs.
