HS Code 2934Nucleic acids and their salts, whether or not chemically defined; other heterocyclic compounds
6 six-digit codes · Heading 34 of 42 in Chapter 29 · World Customs Organization Harmonized System
HS code 2934 is the home of nucleic acids and their salts, plus ring-shaped organic compounds that no other heading claims. Below, each subheading is explained in plain words, with steps to choose the right one.
Goods answering to “Nucleic acids and their salts, whether or not chemically defined; other heterocyclic compounds” split into 6 six-digit codes, 293410 through 293499. Each one carries its own customs description, and the exact wording below is what a classification has to match. The heading is number 34 of 42 in Chapter 29, Organic chemicals, which runs to 410 six-digit codes in all.
Six-digit codes under heading 2934
| HS Code | Import–export description |
|---|---|
| 293410 | Heterocyclic compounds; containing an unfused thiazole ring (whether or not hydrogenated) in the structure |
| 293420 | Heterocyclic compounds; containing in the structure, a benzothiazole ring-system (whether or not hydrogenated), not further fused |
| 293430 | Heterocyclic compounds; containing in the structure, a phenothiazine ring-system (whether or not hydrogenated), not further fused |
| 293491 | Heterocyclic compounds; other heterocyclic compounds, n.e.c. in 2934.1, 2934.2 and 2934.3 |
| 293492 | Heterocyclic compounds; other fentanyls n.e.c. in 2934, and their derivatives |
| 293499 | Nucleic acids and their salts, other heterocyclic compounds, n.e.c. in heading number 2934 |
What product does HS code 2934 refer to?
A heterocyclic compound is built around a ring of atoms. At least one atom in that ring is not carbon. Heading 2934 gathers several kinds of these rings, and it also takes nucleic acids and their salts.
Nucleic acids are the family that includes DNA and RNA. The heading accepts them whether or not they are chemically defined, so a mixture or an impure product can still fit.
India often calls the same number HSN code 2934. The first six digits come from the World Customs Organization, so the base meaning is shared. A country may add extra digits after those six.
The classification path runs from Section VI down to this heading, and then to one of its subheadings.
The subheadings of 2934 in plain words
The table above gives the exact legal text. Here is what each line means in everyday language. The term n.e.c. means not elsewhere classified. The phrase whether or not hydrogenated means the ring may carry extra hydrogen atoms and still count.
- 293410: compounds with one thiazole ring that is not joined to another ring.
- 293491: other ring compounds that do not fit the first three lines.
- 293499: nucleic acids and their salts, and any other ring compound left over.
How to choose the right 2934 code
Work from the most specific line to the most general one.
First, look at the ring in your product. A single thiazole ring points to 293410. Check the words not further fused. If the ring is joined to more rings, the product may belong somewhere else.
Second, ask whether the product is a fentanyl or a derivative of one. If so, look at 293492.
Third, use the two leftover lines. Choose 293491 for other ring compounds in the same group as the first three lines. Choose 293499 for nucleic acids and their salts, and for ring compounds named nowhere else in the heading.
If you are unsure, test your product description in the HS code classifier before you file. Then compare its answer with the legal text of the code.
2934 vs related headings 2932, 2933 and 2935
Three nearby headings often cause mix-ups. The deciding factor is the type of atom inside the ring.
Heading 2932 is for ring compounds whose non-carbon atoms are oxygen only. Heading 2934 takes the other cases, such as the thiazole family, which carries sulphur in the ring.
Heading 2935 is different again. It covers sulphonamides, which are defined by a chemical group and not by a ring. A product with sulphur in its structure may also be a candidate for organo-sulphur compounds in heading 2930. Read each heading text before you decide.
When two headings seem to fit, the more specific wording usually wins. Keep your supplier's product sheet at hand to confirm.

HS Code 2934: common questions
What is HS code 2934?
It is a heading for ring-shaped organic compounds that are not placed in 2932 or 2933, together with nucleic acids and their salts.
Can a mixed or impure product fit heading 2934?
Yes for nucleic acids, because the heading accepts them whether or not they are chemically defined. Check the subheading text to be sure.
Which HS code covers nucleic acids and their salts?
They sit in heading 2934, and the residual line 293499 names them. That line also holds other ring compounds not named elsewhere in the heading.
What is the difference between HS 2933 and 2934?
Heading 2933 is for ring compounds with nitrogen as the only non-carbon atom. Heading 2932 is the same idea for oxygen. Heading 2934 takes the other cases, such as thiazole-type rings.
Which HS code covers fentanyl derivatives in heading 2934?
Code 293492 covers other fentanyls not named elsewhere in 2934, and their derivatives.
Is HSN code 2934 the same as the HS number?
Yes, the first six digits match. HSN is the name used in some countries, and local rules may add more digits.
