1 position · 6 subpositions · 11 codes · tasnif.soliq.uz, data as of 14.10.2026
Updated:
Class 02932 "Heterocyclic compounds with oxygen hetero-atom(s) only" belongs to group 029 "Organic chemicals" of the MXIK (IKPU) classifier. It contains 1 position, 6 subpositions and 11 codes. That is 2.6% of all codes in the group.
All subpositions of the class sit in a single position, 02932001 "Heterocyclic compounds with oxygen hetero-atom(s) only". The largest subpositions are "Phenolphthalein" (02932001002, 4), "Thymolphthalein" (02932001008, 2), "Other heterocyclic compounds with oxygen hetero-atom(s) only" (02932001009, 2). 3 of the 6 subpositions hold exactly one code. Other examples: "Tetrahydrofuran", "Glucosamine hydrochloride", "5-(Hydroxymethyl)furfural".
By number of codes the class ranks 16th of 42 in the group. Neighbouring classes: 02931 "Other organo-inorganic compounds" (2 codes) and 02933 "Heterocyclic compounds with nitrogen hetero-atom(s) only" (21 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 2932.

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 "Phenolphthalein"?
The subposition "Phenolphthalein" has code 02932001002: group 029, class 02932, position 02932001 "Heterocyclic compounds with oxygen hetero-atom(s) only". It covers 4 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 "Tetrahydrofuran"?
The subposition "Tetrahydrofuran" has code 02932001004: group 029, class 02932, position 02932001 "Heterocyclic compounds with oxygen hetero-atom(s) only". 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 02932?
As of 14.10.2026, class 02932 "Heterocyclic compounds with oxygen hetero-atom(s) only" has 1 position, 6 subpositions and 11 codes. Every code in the class starts with 02932.
How does class 02932 differ from class 02933?
They are neighbouring classes of group 029. Class 02932 "Heterocyclic compounds with oxygen hetero-atom(s) only" has 1 position and 11 codes; class 02933 "Heterocyclic compounds with nitrogen hetero-atom(s) only" has 1 position and 21 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.
