Class 02916 "Unsaturated acyclic monocarboxylic acids, cyclic monocarboxylic acids, their anhydrides, halides, peroxides and peroxyacids; their derivatives" belongs to group 029 "Organic chemicals" of the MXIK (IKPU) classifier. It contains 1 position, 6 subpositions and 10 codes. That is 2.4% of all codes in the group.
All subpositions of the class sit in a single position, 02916001 "Unsaturated acyclic monocarboxylic acids, cyclic monocarboxylic acids, their…". The largest subpositions are "Benzoic acid" (02916001008, 4), "Other unsaturated acyclic monocarboxylic acids, cyclic…" (02916001009, 2). 4 of the 6 subpositions hold exactly one code. Other examples: "Sodium benzoate", "Potassium sorbate", "Sorbic acid", "Trifluoroacetic acid 99%".
By number of codes the class ranks 17th of 42 in the group. Neighbouring classes: 02915 "Saturated acyclic monocarboxylic acids and their anhydrides…" (31 codes) and 02917 "Polycarboxylic acids, their anhydrides, halides, peroxides and…" (13 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 2916.

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 "Benzoic acid"?
The subposition "Benzoic acid" has code 02916001008: group 029, class 02916, position 02916001 "Unsaturated acyclic monocarboxylic acids, cyclic monocarboxylic acids, their anhydrides, halides, peroxides and peroxyacids; their derivatives". 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 "Potassium sorbate"?
The subposition "Potassium sorbate" has code 02916001002: group 029, class 02916, position 02916001 "Unsaturated acyclic monocarboxylic acids, cyclic monocarboxylic acids, their anhydrides, halides, peroxides and peroxyacids; their derivatives". 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 02916?
As of 14.10.2026, class 02916 "Unsaturated acyclic monocarboxylic acids, cyclic monocarboxylic acids, their anhydrides, halides, peroxides and peroxyacids; their derivatives" has 1 position, 6 subpositions and 10 codes. Every code in the class starts with 02916.
How does class 02916 differ from class 02917?
They are neighbouring classes of group 029. Class 02916 "Unsaturated acyclic monocarboxylic acids, cyclic monocarboxylic acids, their…" has 1 position and 10 codes; class 02917 "Polycarboxylic acids, their anhydrides, halides, peroxides and peroxyacids…" has 1 position and 13 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.
