Updated:
In the MXIK (IKPU) classifier, class 02934 "Nucleic acids and their salts; other heterocyclic compounds" is part of group 029 "Organic chemicals". As of 14.10.2026 it has 1 position and 13 subpositions carrying 15 codes in total. That is 3.6% of all codes in the group.
All subpositions of the class sit in a single position, 02934001 "Nucleic acids and their salts; other heterocyclic compounds". The largest subpositions are "Other nucleic acids and their salts" (02934001016, 3). 12 of the 13 subpositions hold exactly one code. Other examples: "Bromocresol green", "Bromophenol blue", "Phenol red", "Chlorphenamine maleate".
By number of codes the class ranks 9th of 42 in the group. Neighbouring classes: 02933 "Heterocyclic compounds with nitrogen hetero-atom(s) only" (21 codes) and 02935 "Sulphonamides" (3 codes). Under the coding scheme in the Regulation on the National Catalogue, digits 2 to 5 of a goods code are the customs (TN VED, HS-based) code; for this class it is 2934.

How to apply an MXIK code
- Find the subposition of your good or service: the first 11 digits are the group, class, position and subposition.
- Pick the 17-digit code on tasnif.soliq.uz: the last 6 digits are brand and attribute; goods without a barcode use "000000".
- Show this code in electronic invoices (ESF) and online cash register receipts, and for imports in the customs cargo declaration.
- Watch for changes on tasnif.soliq.uz: deleting or changing a code takes effect after 30 days.
- No suitable code? Send a request to the operator through your personal account (reviewed within 3 working days).

Frequently asked questions
What is the MXIK (IKPU) code for "Other nucleic acids and their salts"?
The subposition "Other nucleic acids and their salts" has code 02934001016: group 029, class 02934, position 02934001 "Nucleic acids and their salts; other heterocyclic compounds". It covers 3 codes: all of them start with these 11 digits, and the last 6 digits stand for brand and attribute. The exact 17-digit code is chosen on tasnif.soliq.uz.
What is the MXIK (IKPU) code for "Phenol red"?
The subposition "Phenol red" has code 02934001012: group 029, class 02934, position 02934001 "Nucleic acids and their salts; other heterocyclic compounds". It covers one 17-digit MXIK code starting with these 11 digits. The exact 17-digit code is chosen on tasnif.soliq.uz.
How many MXIK codes are in class 02934?
As of 14.10.2026, class 02934 "Nucleic acids and their salts; other heterocyclic compounds" has 1 position, 13 subpositions and 15 codes. Every code in the class starts with 02934.
How does class 02934 differ from class 02935?
They are neighbouring classes of group 029. Class 02934 "Nucleic acids and their salts; other heterocyclic compounds" has 1 position and 15 codes; class 02935 "Sulphonamides" has 1 position and 3 codes. The class is digits 4–5 of the MXIK code, so a wrong class changes the base code of the item.
Where must the MXIK code be shown?
Under the Regulation on the National Catalogue (Cabinet of Ministers Resolution No. 263 of 28 April 2025) the catalogue is used for electronic invoices, online cash register receipts and the customs cargo declaration (except goods imported for the first time). A code that does not match the base code (first 11 digits) can lead to a fine of 1% of the value under Article 223(5) of the Tax Code.
