Amendments to the Rulebook on the Chemicals Register (Official Gazette of RS 24/2026): what changes and from when
22/03/2026 | By Ivan Milenković
The 2026 amendments to the Rulebook on the Chemicals Register were published in the Official Gazette of RS, No. 24/2026, on March 13, 2026. The rulebook enters into force on the eighth day after publication.
If you are just completing your eIRH report for 2025, these amendments do not concern you right now. The report for 2025 is submitted under the existing tariff codes. The new codes apply to reporting data for 2026. Knowing about the amendments in good time is important for updating internal records, ERP systems and software databases.
Still, knowing about the amendments in good time is important for updating internal records, ERP systems and software databases before the next reporting period.
What Annex 1 is
The basis of eIRH reporting is Annex 1 of the Rulebook: the List of customs tariff codes of chemicals that are entered in the Chemicals Register. If a chemical cannot be classified under any of the listed codes, there is no obligation to register it.
Amendments to the list follow updates of the Customs Tariff. Some codes are made more granular (one is split into two or three), some are restructured, and occasionally the classification criteria change.
Verified changes in Annex 1
The following overview is based on a comparison of the consolidated text from the Official Gazette of RS 10/2024 and the new text from the Official Gazette of RS 24/2026.
Restructured tariff codes
These substances remain in the Register, but the old codes have been replaced with new ones. Companies that have them in their records need to update them before the next reporting cycle.
| Old code | Description (old) | New code(s) | Description (new) |
|---|---|---|---|
| 2710 19 43 00 | Fuel oil (with a sulphur content ≤0.001%) | 2710 19 42 00 | Fuel oil with a bio-carbon content ≥80% by mass |
| 2710 19 44 00 | Fuel oil, other | ||
| 2903 89 80 00 | Halogenated compounds, other | 2903 89 20 00 | Hexabromocyclododecane (HBCD) |
| 2903 89 70 00 | Halogenated compounds, other | ||
| 2929 90 00 00 | Compounds with an N-N bond, other | 2929 90 10 00 | N,N-dimethylphosphoramidic dichloride |
| 2929 90 90 00 | Compounds with an N-N bond, other | ||
| 2930 90 98 10 | Dithiocarbonates (xanthates) | 2930 90 95 10 | Dithiocarbonates (xanthates) |
| 2930 90 98 90 | Organo-sulphur compounds, other | 2930 90 95 90 | Organo-sulphur compounds, other |
| 2931 49 90 00 | Organo-phosphorus compounds, other | 2931 49 50 00 | Bis(1-methylpentyl) methylphosphinate |
| 2931 49 60 00 | Butyl methylphosphinate | ||
| 2931 49 80 00 | Organo-phosphorus compounds, other | ||
| 3102 10 10 00 | Urea in aqueous solution (>45% nitrogen) | 3102 10 12 00 | Urea in aqueous solution, 31.8–33.2% by mass |
| 3102 10 15 00 | Urea in aqueous solution, 33.2–55% by mass | ||
| 3102 10 19 00 | Urea in aqueous solution, other | ||
| 8107 20 00 00 | Unwrought cadmium; powders (heading 8107) | 8112 69 10 00 | Unwrought cadmium; powders (heading 8112) |
New specific position
| New code | Description |
|---|---|
| 2930 90 80 00 | Phorate (ISO) |
Phorate is an organophosphorus pesticide that was previously covered by more general codes. It now has an explicit position in Annex 1.
Removed tariff codes (without replacement)
| Removed code | Description |
|---|---|
| 2710 12 59 00 | Motor spirit, with a lead content >0.013 g/l, RON ≥98 |
| 3213 10 00 00 | Colours in sets |
| 3822 90 00 00 | Diagnostic or laboratory reagents, other |
What this means in practice
Urea in aqueous solution. The old code 3102 10 10 00 no longer exists. It has been replaced by three subcodes divided by concentration ranges. This directly concerns distributors and users of AdBlue fluid (a reagent for SCR systems, typically 32.5% urea) and liquid urea fertilizers. Before the next report, determine which of the new ranges matches your product.
HBCD. Hexabromocyclododecane is a substance of concern with POP status. Until now it shared a code with “other” halogenated compounds. Separating it into its own tariff position improves the visibility of this substance in register data. Companies that have it recorded under the old code 2903 89 80 00 should update it.
Fuel oil. The classification criterion changes: instead of sulphur content, the basis is now bio-carbon content. Importers and distributors should determine which range matches their specific products.
Organo-phosphorus compounds (2931 49). Two specific substances (bis(1-methylpentyl) methylphosphinate and butyl methylphosphinate) are separated from the general category. This mainly affects specialized chemical distributors and processors.
Cadmium. The reclassification from heading 8107 to 8112 does not change the chemical substance or the obligation to register it. Only the tariff position under which the chemical is reported changes.
Colours in sets. Code 3213 10 00 00 has been removed without replacement. Colours in sets no longer fall under the Register on this basis. If you have such products in your records, check whether an alternative active customs tariff code exists for them.
Practical steps before the next reporting period
Before reporting data for 2026, I recommend the following steps:
- Review your internal inventory of chemicals and find all products recorded under the codes from the table of restructured positions.
- For each such product, determine which new code matches its specific specification. Pay particular attention to:
- urea (which concentration range?) and
- fuel oil (what bio-carbon share?).
- Update internal documentation and software records.
- For chemicals recorded under code 3213 10 00 00, check whether an alternative active customs tariff code exists.
If you are not sure whether an amendment applies to your specific case, consulting a chemical adviser may be the fastest way to a clear answer.
