HS Code for Nucleic acids
Nucleic acids and their salts are classified under HS code 2934.99, which falls within Chapter 29 of the Harmonized System. Chapter 29 is reserved for organic chemicals. Heading 2934 covers "Nucleic acids and their salts, whether or not chemically defined; other heterocyclic compounds." This heading is a catch-all for complex organic structures that contain a heterocyclic ring—a ring containing atoms of at least two different elements. Nucleic acids, such as DNA and RNA, are complex molecules consisting of a sugar, a phosphate group, and a nitrogenous base, making them heterocyclic. Subheading 2934.99 is the residual category for these compounds that are not specifically named in other subheadings of 2934. Classification here requires that the product be a separate chemically defined compound, although the heading specifically allows for nucleic acids to be "whether or not chemically defined" due to their biological complexity. This code is essential for the trade of raw biotechnological materials used in research, pharmaceuticals, and genetic engineering.
Products Included
- Deoxyribonucleic acid (DNA)
- Ribonucleic acid (RNA)
- Synthetic oligonucleotides
- Nucleoside phosphonates
- Salts of nucleic acids (e.g., sodium salts)
- Plasmids and vectors in purified form
Common Misclassification
Nucleic acids are often misclassified under heading 3002, which covers blood, antisera, vaccines, and similar products. While nucleic acids are biological in origin, 3002 is reserved for products prepared for therapeutic or prophylactic use. If the nucleic acid is part of a diagnostic kit, it may be classified under 3822. Additionally, simple heterocyclic compounds with only nitrogen hetero-atoms might be confused with heading 2933. The presence of the phosphate-sugar backbone in nucleic acids typically points toward 2934.99.
FAQ
What is the HS code for nucleic acids?
