50 classes · 112 subpositions · 623 codes · tasnif.soliq.uz, data as of 14.10.2026
Updated:
As of 14.10.2026, group 028 "Inorganic and organic chemical products" holds 623 codes, 0.14% of all MXIK (IKPU) codes (ranked 46th of 117). They are split across 50 classes, 54 positions and 112 subpositions.
The largest classes by number of codes are 02835 "Phosphinates, phosphonates, phosphates and polyphosphates" (62, 10%), 02833 "Sulphates; alums; peroxosulphates (persulphates)" (55, 8.8%), 02827 "Chlorides, chloride oxides and chloride hydroxides; bromides and…" (50, 8%). Its largest subposition is "Sulphates" (02833001001, 50 codes). 11 classes have their own pages; the other 39 are shown in full in the table below.
The most compact classes are 02839 "Silicates" (1 code) and 02845 "Isotopes" (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).
