Chestny Znak in 1C: how to work with it, export codes, and configure cash registers in 2026

Start with the product group, the organization's role, and the operation. The same item may arrive via OSU with a GTIN and quantity, then be sold with mandatory scanning of each package code. Recording individual shipment codes and scanning them at checkout serve different purposes.

The cosmetics manufacturer's MDM is specified in the GIS MT account profile. As of the review date, including it in the withdrawal document for this group remains optional: do not treat its absence as a general write-off ban. For other goods, check the stage by TN VED/OKPD2 and your group's rules. In the September review, record separately which operations are already mandatory, which start in October, and who will verify the result in GIS MT.

First determine the disposal reason and the product group's accounting format. In retail sales, the cashier scans the Data Matrix, and sales data is sent through the cash register and fiscal data operator. Preliminary validation with sale blocking is used where the authorization mode is already active. For other reasons—write-off, defects, internal use or export—create a document with the reason and data in the required format: GTIN and quantity or individual codes.

From October 1, 2026, for canned goods that are defective, expired, or disposed of, withdrawal data must be submitted within three business days after the write-off report is prepared. OSU applies to most such reasons; retail, online sales, and vending require an item-level format. If the shipment arrived via OSU, individual codes for item-level withdrawal must be counted from the packages.

If there are many scenarios, design it integrating 1C with Chestny Znak as a process with logs, notifications, and an error owner.

Auto-signing is useful only where control is clear: which documents may be signed automatically, who handles exceptions, and where it is visible that the UTD is stuck. The basic setup is this: the qualified electronic signature and permissions are configured for the organization, outbound UTDs are checked for details and codes, then a scheduled job sends the document to the EDI operator, and the log shows the statuses "created", "signed", "sent", "accepted", "rejected".

For the business process, the important thing is not the "sign automatically" button, but the procedure: who is allowed to auto-sign, which checks are mandatory before sending, and who resolves the error before shipment is blocked.

The authorization mode checks the code before the receipt is issued and blocks the sale when a prohibition ground is established. It applies according to the product-group calendar. For cosmetics and household chemicals, retail disposal becomes mandatory in July 2026, while the authorization mode starts on April 1, 2027. Including the code in the receipt does not, by itself, mean that all cash-register blocks are already mandatory. The PiOT technical solution is required for participants who sell through cash registers and must perform authorization checks under Resolution No. 1944.

Chestny Znak's September 10, 2026 clarification states that X-APIKEY continues to work technically after July 1, but the absence of a PIoT technical solution is recorded as a deviation. A working token does not remove the obligation to install an available compatible solution. Check the POS model, checkout software, and module version in the official calculator; if no solution is available, monitor the registry with the checkout software provider.

Check the checkout system's current POS driver, fiscal data format, product group settings, OFD connection, and response log. Analyze rejections by cause: connection errors, incorrect settings, and sales restrictions require different actions.

In the working loop 1C holds the item master, batches, movement documents, code statuses and the link to source operations. The other systems cover their own areas: EDI transmits the UPD document, GIS MT stores the code state, SUZ issues codes, the cash register retires goods from circulation, scanners and WMS record actual movement.

If gaps remain after the checklist - assess your 1C readiness for product marking: we will review your setup and show what to resolve before going live.
