Updated:
In the MXIK (IKPU) classifier, class 02917 "Polycarboxylic acids, their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives" is part of group 029 "Organic chemicals". As of 14.10.2026 it has 1 position and 11 subpositions carrying 13 codes in total. That is 3.1% of all codes in the group.
All subpositions of the class sit in a single position, 02917001 "Polycarboxylic acids, their anhydrides, halides, peroxides and peroxyacids…". The largest subpositions are "Succinic acid" (02917001005, 2), "Other polycarboxylic acids, their anhydrides, halides, peroxides and…" (02917001012, 2). 9 of the 11 subpositions hold exactly one code. Other examples: "Ammonium oxalate", "Sodium oxalate", "Potassium hydrogen phthalate", "Isomethyltetrahydrophthalic anhydride".
By number of codes the class ranks 11th of 42 in the group. Neighbouring classes: 02916 "Unsaturated acyclic monocarboxylic acids, cyclic monocarboxylic…" (10 codes) and 02918 "Carboxylic acids with additional oxygen function and their…" (37 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 2917.

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 "Succinic acid"?
The subposition "Succinic acid" has code 02917001005: group 029, class 02917, position 02917001 "Polycarboxylic acids, their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives". It covers 2 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 hydrogen phthalate"?
The subposition "Potassium hydrogen phthalate" has code 02917001006: group 029, class 02917, position 02917001 "Polycarboxylic acids, their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated 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 02917?
As of 14.10.2026, class 02917 "Polycarboxylic acids, their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives" has 1 position, 11 subpositions and 13 codes. Every code in the class starts with 02917.
How does class 02917 differ from class 02918?
They are neighbouring classes of group 029. Class 02917 "Polycarboxylic acids, their anhydrides, halides, peroxides and peroxyacids…" has 1 position and 13 codes; class 02918 "Carboxylic acids with additional oxygen function and their anhydrides…" has 1 position and 37 codes. The class is digits 4–5 of the MXIK code, so a wrong class changes the base code of the item.
What if there is no suitable MXIK code?
According to the official tasnif.soliq.uz FAQ, codes are searched by subposition name, brand, barcode or the first 4 digits of the customs (TN VED) code, via the site questionnaire or in the Excel export of the database. If nothing fits, a request is sent to the catalogue operator through the personal account; it is reviewed within 3 working days.
