6 positions · 20 subpositions · 536 codes · tasnif.soliq.uz, data as of 14.10.2026
Updated:
Class 08504 "Electrical transformers, static converters (for example, rectifiers) and inductors" accounts for 536 codes in group 085 "Electrical machinery and equipment; parts thereof". They are spread across 6 positions and 20 subpositions. That is 1% of all codes in the group.
The largest position is 08504002 "Liquid dielectric transformers" with 369 codes (69% of the class). It is followed by 08504003 "Static converters" with 72. The largest subpositions are "Electrical transformer" (08504002001, 256), "Packaged transformer substation" (08504002006, 113), "Chargers and power supplies (all kinds and for all devices)" (08504003009, 53). 9 of the 20 subpositions hold exactly one code. Other examples: "Mine lighting unit (AOSh)", "Rectifier unit", "Current-limiting reactor", "Ballasts".
By number of codes the class ranks 13th of 47 in the group. Neighbouring classes: 08503 "Parts suitable for use solely or principally with the machines of…" (3 codes) and 08505 "Electromagnets" (7 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 8504.

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 "Electrical transformer"?
The subposition "Electrical transformer" has code 08504002001: group 085, class 08504, position 08504002 "Liquid dielectric transformers". It covers 256 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 "Mine lighting unit (AOSh)"?
The subposition "Mine lighting unit (AOSh)" has code 08504006001: group 085, class 08504, position 08504006 "Other transformers". 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 08504?
As of 14.10.2026, class 08504 "Electrical transformers, static converters (for example, rectifiers) and inductors" has 6 positions, 20 subpositions and 536 codes. Every code in the class starts with 08504.
How does class 08504 differ from class 08505?
They are neighbouring classes of group 085. Class 08504 "Electrical transformers, static converters (for example, rectifiers) and…" has 6 positions and 536 codes; class 08505 "Electromagnets" has 3 positions and 7 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.
