HS-6 · Subheading
291735
Acids; aromatic polycarboxylic acids; phthalic anhydride
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 291735 when importing or exporting phthalic anhydride, a key chemical used in making plastics and resins. For instance, if you're shipping 1,000 kg of phthalic anhydride in bulk containers, this code applies.
This code specifically covers aromatic polycarboxylic acids, particularly phthalic anhydride, which is crucial in the production of plasticizers and coatings. In contrast, HS-6 291736 covers other derivatives of phthalic acid, which may have different applications.
Phthalic anhydride is often found in products like alkyd resins and certain dyes, making it essential for manufacturers in the paint and coating industries. If you're dealing with a shipment that includes this compound, ensure you're using the correct HS code to avoid customs issues.
When classifying your product, remember that phthalic anhydride is distinct from non-aromatic polycarboxylic acids, which fall under different HS codes. This distinction is important for compliance and tariff purposes.
