MXIK (IKPU) codes, class 02912: Aldehydes, whether or not with other oxygen function; cyclic polymers of aldehydes; paraformaldehyde
1 position · 5 subpositions · 5 codes · tasnif.soliq.uz, data as of 14.10.2026
Updated:
Class 02912 "Aldehydes, whether or not with other oxygen function; cyclic polymers of aldehydes; paraformaldehyde" accounts for 5 codes in group 029 "Organic chemicals". They are spread across 1 position and 5 subpositions. That is 1.2% of all codes in the group.
All subpositions of the class sit in a single position, 02912001 "Aldehydes, whether or not with other oxygen function; cyclic polymers of…". Every subposition of the class holds exactly one code. Other examples: "Acyclic aldehydes", "Vanillin (4-hydroxy-3-methoxybenzaldehyde)", "Formalin", "Cyclic aldehydes".
By number of codes the class ranks 24th of 42 in the group. Neighbouring classes: 02911 "Acetals and hemiacetals, whether or not with other oxygen function…" (1 code) and 02913 "Halogenated, sulphonated, nitrated or nitrosated derivatives of…" (1 code). 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 2912.

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 "Acyclic aldehydes"?
The subposition "Acyclic aldehydes" has code 02912001001: group 029, class 02912, position 02912001 "Aldehydes, whether or not with other oxygen function; cyclic polymers of aldehydes; paraformaldehyde". It covers one 17-digit MXIK code starting with these 11 digits. The exact 17-digit code is chosen on tasnif.soliq.uz.
What is the MXIK (IKPU) code for "Cyclic aldehydes"?
The subposition "Cyclic aldehydes" has code 02912001005: group 029, class 02912, position 02912001 "Aldehydes, whether or not with other oxygen function; cyclic polymers of aldehydes; paraformaldehyde". 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 02912?
As of 14.10.2026, class 02912 "Aldehydes, whether or not with other oxygen function; cyclic polymers of aldehydes; paraformaldehyde" has 1 position, 5 subpositions and 5 codes. Every code in the class starts with 02912.
How does class 02912 differ from class 02913?
They are neighbouring classes of group 029. Class 02912 "Aldehydes, whether or not with other oxygen function; cyclic polymers of…" has 1 position and 5 codes; class 02913 "Halogenated, sulphonated, nitrated or nitrosated derivatives of products of…" has 1 position and 1 code. 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.
