Updated:
As of 14.10.2026, group 084 "Nuclear reactors, boilers, machinery and mechanical appliances; parts thereof" holds 35,548 codes, 8% of all MXIK (IKPU) codes (ranked 5th of 117). They are split across 86 classes, 237 positions and 468 subpositions.
The largest classes by number of codes are 08481 "Taps, cocks, valves and similar appliances for pipes, boiler shells…" (7,890, 22%), 08415 "Air conditioners, air conditioning machines and parts thereof" (6,583, 19%), 08418 "Refrigerators, freezers and parts thereof" (5,755, 16%). Its largest subposition is "Household refrigerators (including combined refrigerator-freezers)" (08418001001, 4,833 codes). 43 classes have their own pages; the other 43 are shown in full in the table below.
The most compact classes are 08478 "Machinery for preparing or making up tobacco" (1 code) and 08487 "Machinery parts, not containing electrical connectors, insulators…" (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).
