MXIK (IKPU) codes, group 029: Organic chemicals
42 classes · 271 subpositions · 422 codes · tasnif.soliq.uz, data as of 14.10.2026
Updated:
Group 029 "Organic chemicals" brings together 42 classes, 42 positions and 271 subpositions: 422 codes in total, or 0.09% of the MXIK (IKPU) classifier. By number of codes it ranks 50th of 117 groups.
The largest classes by number of codes are 02905 "Acyclic alcohols and their halogenated, sulphonated, nitrated or…" (54, 13%), 02918 "Carboxylic acids with additional oxygen function and their…" (37, 8.8%), 02922 "Oxygen-function amino-compounds" (34, 8.1%). Its largest subposition is "Monosodium glutamate" (02922001011, 18 codes). 20 classes have their own pages; the other 22 are shown in full in the table below.
The most compact classes are 02938 "Glycosides, natural or synthetic, and their salts, ethers, esters…" (1 code) and 02942 "Other organic compounds" (1 code). The group code is the first three digits of an MXIK; under the scheme in the Regulation on the National Catalogue, digits 2 to 5 of a goods code match the customs (TN VED, HS-based) code.

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).

It covers 18 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 "Other cyclic hydrocarbons"?
The subposition "Other cyclic hydrocarbons" has code 02902001008: group 029, class 02902, position 02902001 "Cyclic hydrocarbons". It covers 16 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.
How many MXIK codes are in group 029?
As of 14.10.2026, group 029 "Organic chemicals" has 422 codes in 271 subpositions. All of them start with 029.
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.
