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).

As of 14.10.2026, class 02804 "Hydrogen, rare gases and other non-metals" has 2 positions, 10 subpositions and 19 codes. Every code in the class starts with 02804.
How does class 02804 differ from class 02805?
They are neighbouring classes of group 028. Class 02804 "Hydrogen, rare gases and other non-metals" has 2 positions and 19 codes; class 02805 "Alkali or alkaline-earth metals; rare-earth metals, scandium and yttrium…" has 1 position and 3 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).
