Updated:
Class 02921 "Amine-function compounds" belongs to group 029 "Organic chemicals" of the MXIK (IKPU) classifier. It contains 1 position, 10 subpositions and 12 codes. That is 2.8% of all codes in the group.
All subpositions of the class sit in a single position, 02921001 "Amine-function compounds". The largest subpositions are "Sulphanilic acid, including acyclic monoamines" (02921001003, 2), "Acyclic polyamines and their derivatives" (02921001013, 2). 8 of the 10 subpositions hold exactly one code. Other examples: "Diethylamine", "Diphenylamine", "Benzidine", "Diphenhydramine hydrochloride (diphenhydramine)".
By number of codes the class ranks 13th of 42 in the group. Neighbouring classes: 02920 "Esters of other inorganic acids of non-metals (excluding esters of…" (1 code) and 02922 "Oxygen-function amino-compounds" (34 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 2921.

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).
