Item-level tracking from December 2026: how to prepare production
What changes on the line, in document flow and in the manufacturer’s warehouse records.
There is no declaration and no certificate here. Instead there is special registration, mandatory hallmarking and traceability of each item in a separate state system.
Jewellery is one more category that lives outside technical regulations. There is no declaration and no certificate here. Instead there is state control over the circulation of precious metals, mandatory assaying and hallmarking, and traceability of each item in a separate information system. A seller who comes from ordinary retail usually underestimates the amount of requirements.
The circulation of precious metals and stones is a separate area of regulation. There are three key elements:
The technical regulations of the Union do not apply to jewellery, so it makes no sense to look for a TR CU for it or to issue a declaration.
These are three concepts that people confuse, although they are different things.
| What | What it means | Who applies it |
|---|---|---|
| Fineness | The content of precious metal in the alloy | Determined during assaying |
| Manufacturer’s mark | The manufacturer’s sign with its code and year | The manufacturer, by agreement with the control authority |
| State assay hallmark | Confirmation of the fineness by the state | The assay supervision authority |
A domestically made item without a manufacturer’s mark and a hallmark is not released into free circulation. Imports have their own procedure: imported items also go through assaying and hallmarking, and you cannot sell them before that.
Each item has a unique number, and its whole life, from production or import to the sale to the final buyer, is shown in the state information system. For the seller this means a set of routine duties.
The logic is the same as in the labelling of ordinary goods: a discrepancy between the system and the warehouse is already a violation, even if nothing has been lost. A related topic is covered in the article on item-by-item accounting.
The marketplaces treat this category strictly: it needs a special status of the seller and work with traceability, so you cannot sell it “as an ordinary product”.
A frequent mistake of newcomers is an attempt to sell items made of precious metals as costume jewellery, to avoid the requirements. This is exposed at the first check of the description and the composition.
The description of the inserts is the place where disputes with buyers arise most often: a natural, an enhanced and a synthetic stone must be clearly distinguished in the description. Silence here is treated as misleading the consumer.
The most expensive mistake in imports is to count on a quick sale right after customs clearance. Between the arrival of the batch and the right to sell it there is a procedure that you cannot skip and that is hard to speed up.
| Mistake | Consequence |
|---|---|
| Sale without special registration | The activity is carried out in violation of the rules |
| Items without a hallmark and a manufacturer’s mark on sale | Seizure of the products |
| A precious metal is sold as costume jewellery | Avoidance of the requirements; it is exposed by the composition |
| The stock differs from the information system | A violation of the records |
| A synthetic stone is described as natural | Misleading the consumer |
| The fineness or the weight is not stated | A violation of the sales rules |
If it turns out that the items are made of non-precious alloys, the requirements will be completely different, and then the starting point will be the lists of products and the choice of the form of the document.
