HS-4 · Heading
2916 — Acids; unsaturated acyclic monocarboxylic, cyclic monocarboxylic, their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives
Chapter 29: Organic chemicals
Plain-language overview
Use HS-4 2916 when importing or exporting unsaturated acyclic monocarboxylic acids, such as acrylic acid or methacrylic acid. For example, if you're shipping acrylic acid in bulk containers for use in adhesives, this is the correct heading.
When choosing among the HS-6 lines, consider the specific type of acid. For instance, HS-291611 covers acrylic acid and its salts, while HS-291613 is for methacrylic acid and its salts. Ensure you select the line that matches your product's chemical composition.
If your product is an ester of acrylic acid, you'll want to classify it under HS-291612. On the other hand, if it’s an ester of methacrylic acid, HS-291614 is the appropriate choice. Understanding these distinctions is crucial for accurate classification.
For products that don't fit neatly into the previous categories, such as certain derivatives or mixtures, HS-291619 is a catch-all for unsaturated monocarboxylic acids and their derivatives not specifically listed elsewhere.
