What laws a marketplace seller must comply with: receipts, labeling, certification
A marketplace seller lives in five legal blocks at once: 54-FZ on cash registers (under the agency scheme the platform issues the receipt), Chestny ZNAK labeling, TR CU certification with fines up to 600,000 RUB under Art. 14.43 of the Administrative Code, taxes (NPD, simplified regime, VAT above 60M RUB) and marketplace law 289-FZ from March 1, 2026. A breakdown: the compliance map, how an AI lawyer for sellers differs from a reference system and a template builder, step-by-step setup, a comparison, a checklist — and honest limits: the agent does not replace a lawyer in court.

In short (as of July 2026). A marketplace seller in Russia has to comply with several bodies of law at once: Federal Law 54-FZ on cash registers (under the agency scheme the marketplace itself issues the receipt to the buyer; your own register is only needed for direct sales), mandatory "Chestny ZNAK" labeling (clothing, footwear, perfume, dietary supplements and a dozen more categories), certification and declaration under EAEU technical regulations (fines under Art. 14.43 of the Administrative Code run up to 300,000 RUB for sole proprietors and 600,000 RUB for companies), the Tax Code (NPD, simplified taxation, patent; since 2025 a sole proprietor on the simplified regime with revenue above 60M RUB pays VAT), and, from March 1, 2026, the marketplace law 289-FZ. Tracking all of this by hand is hard: the requirements depend on the product category, the business form and the fulfillment scheme. The Samreshuuu AI agent, with its "Seller legal" expert skill, answers these questions for your specific situation, drafts documents and checks product requirements — but, honestly: it does not replace a lawyer in court. Below is the compliance map and how to cover it.
The seller's legal map: five blocks of requirements
The rules for a marketplace seller are not collected in one law — they are spread across cash-register, tax, technical and "platform" regulation. Here is what the picture is made of.
- Online cash registers (54-FZ). The newcomer's classic question is whether you need a cash register to trade on a marketplace. Good news: when you sell through Wildberries, Ozon or Yandex Market under the agency scheme, the marketplace itself forms the buyer's receipt — it accepts the payment and acts as the seller's agent. Your own register is needed for direct sales: your own website accepting payments, an offline store, taking money directly from a buyer. Self-employed sellers (NPD) need no register at all — receipts are generated in the "Moy Nalog" app.
- "Chestny ZNAK" product labeling. Footwear and medicines have been labeled since 2020, clothing and textiles since 2021, supplements and antiseptics since 2024, soft drinks, pet food and bicycles since 2025. The seller registers in the system, orders Data Matrix codes (0.5 RUB per code, VAT excluded), applies them to each unit, puts them into circulation and, when shipping to the marketplace warehouse, passes the codes via electronic document exchange (EDO). Selling unlabeled goods costs 5,000–10,000 RUB for sole proprietors and 50,000–100,000 RUB for companies, with confiscation — and above 1.5M RUB the case becomes criminal under Art. 171.1 of the Criminal Code.
- Certification and declaration. Children's goods and toys require a certificate of conformity, clothing and electronics a declaration, cosmetics a declaration plus a state registration certificate (SGR); if the product is not subject to mandatory assessment, the marketplace may still ask for a rejection letter. Documents for goods imported from China are issued to the importer — that is, to you: a Chinese manufacturer's certificate is not valid in Russia. Liability sits with the seller, not the platform: under Art. 14.43 of the Administrative Code — 100,000–300,000 RUB for sole proprietors and 300,000–600,000 RUB for companies, up to 1M RUB with confiscation for repeat violations.
- Taxes and business form. Self-employment fits only goods of your own making and up to 2.4M RUB per year — resale and labeled goods are off limits on NPD. Most sellers run as sole proprietors on the simplified regime, 6% of revenue or 15% of profit; since 2024 online retail is also allowed on a patent. The big recent change: since 2025 a sole proprietor on the simplified regime with revenue above 60M RUB per year pays VAT (5% up to 250M, 7% up to 450M — or the standard rates with deductions). A detailed breakdown of the regimes is in how to choose a tax regime for a sole proprietor.
- The platform's offer and the marketplace law. The marketplace offer is a contract of adhesion (Art. 428 of the Civil Code): you accept the terms as a whole, and the platform changes them unilaterally. From March 1, 2026, law 289-FZ of 31.07.2025 phases in: the marketplace must provide a full sales report with a breakdown of every deduction at least monthly, give 30 days' notice of changes to essential terms, may not fine sellers for things absent from the contract, and may not enroll a seller in promotions without explicit consent.
Why "read it once" does not work
The problem is not that the requirements are complex — it is that they keep moving. The list of labeled categories grows every year. Platform tariffs and offers get rewritten with a couple of weeks' notice. VAT thresholds and simplified-regime rates shift with the new tax year. What you learned when entering the marketplace is partially stale six months later.
Ordinary tools cover this piecemeal. Legal reference systems give you the text of the law but do not answer "which of this applies to my kids' backpacks on FBS". Document builders assemble a claim from a template but will not check whether your product needs certification. A subscription lawyer answers everything, but for a fee and not instantly — and he does not see your seller account. The marketplace's built-in help is written by the platform and will not warn you about the traps in its own offer.
An AI lawyer for the seller: what the agent takes over
An AI lawyer inside the agent covers the job end to end: it holds the context of your business (form, tax regime, product categories, FBO/FBS scheme), answers questions against that context, drafts documents and monitors changes on a schedule.
Setup in plain words, not development
You do not program Samreshuuu or fill out configuration forms — you explain the task in plain language, like to an employee:
"Check whether kids' backpacks are subject to mandatory certification and labeling, and which documents Wildberries will ask for when I upload the product card."
"Build a document checklist for launching on Ozon as a sole proprietor on the 6% simplified regime: cash register, EDO, certificates, labeling."
"Wildberries fined me for a dimensions mismatch — draft a pre-court claim with references to the offer clauses and the Civil Code."
"Once a week, check for changes in the Wildberries and Ozon offers and tariffs and send me a digest of what affects me."
The "Seller legal" expert skill activates on its own — nothing to switch on. It covers choosing a business form, certification, labeling, dissecting platform offers, disputing fines, unblocking a seller account, trademarks and parallel import.
How to put seller compliance on an agent: step by step
- Describe the business. Form (self-employed, sole proprietor, LLC), tax regime, product categories, fulfillment scheme (FBO/FBS), platforms. This is the context every answer will be anchored to.
- Connect the seller accounts. Via the official APIs — as described in how to connect AI to Wildberries and how to connect AI to Ozon. Then the agent sees real data: a fine in the finance report, a deduction, a rejected shipment — and can tie a legal question to a concrete event in the account.
- Set the rules in words. What to verify before every new product card, which documents to keep at hand, which changes to warn about.
- Turn on "draft → approval". Everything that goes outside — a claim, an appeal, a reply to the platform — the agent prepares as a draft, and you send it after review. For legal documents this is the right default.
- Put checks on a schedule. A weekly digest of offer changes, a monthly re-check of requirements for your categories — the agent runs on schedule by itself, no reminders needed.
Comparison: who can do what
| Task | Legal reference system | Document builder | Subscription lawyer | AI agent (Samreshuuu) |
|---|---|---|---|---|
| Find the text of a law | yes | no | yes | yes |
| Answer "do I personally need a cash register" | no | no | yes | yes |
| Check a category for labeling and certification | partially | no | yes | yes |
| Draft a pre-court claim over a fine | no | template | yes | yes |
| Monitor offer changes on a schedule | no | no | no | yes |
| Tie a question to WB/Ozon account data | no | no | no | yes |
| Represent you in court | no | no | yes | no |
The last row is the principled one. The agent means consultation, documents and monitoring; courtroom representation stays with a human lawyer.
Honest about the downsides
An AI agent does not replace a lawyer where procedural standing is required: in court, at a tax interrogation, in a complex intellectual-property dispute headed for arbitration you need a human with a power of attorney. The agent will draft the claim; the lawyer walks into the hearing.
If you have three SKUs in an unlabeled category, everything was set up long ago and nothing changes — a standing agent is overkill: a one-off consultation is enough. The agent pays off when there are several categories, the assortment grows, you sell on more than one platform and the requirements need continuous tracking rather than a one-time lookup.
And one more thing: the agent's answers are only as good as the honesty of your context. If you do not tell it the goods are resale rather than your own production, it will not guess that the self-employment regime is off the table for you.
The seller's compliance checklist
- Cash register. Selling only through a marketplace under the agency scheme — no separate register for the marketplace is needed, the platform issues the receipt. Running your own website or an offline store — you need your own online register under 54-FZ.
- Labeling. Check your category against the "Chestny ZNAK" list. If it is in scope: register in the system, order Data Matrix codes, put them into circulation, pass the codes to the platform via EDO.
- Certification. Determine the document by category: certificate, declaration, SGR or a rejection letter. For imports the documents are issued to you as the importer.
- Taxes. NPD is for own production only and up to 2.4M RUB. Watch the 60M RUB threshold on the simplified regime — beyond it VAT begins.
- The offer. Save versions of the offer whenever it changes, switch off auto-promotions, and from March 2026 demand itemized reports under 289-FZ.
- Documents at hand. Certificates, supplier contracts, waybills — keep them in one place: when an account gets blocked, the clock runs in days.
Frequently asked questions
What laws must a marketplace seller comply with? The main blocks: 54-FZ on online cash registers (under the agency scheme the marketplace issues the receipt), mandatory "Chestny ZNAK" labeling for listed categories, certification and declaration under EAEU technical regulations (liability under Art. 14.43 of the Administrative Code), the Tax Code (NPD, simplified regime, patent, VAT above 60M RUB of revenue), and the marketplace law 289-FZ, which from March 1, 2026 limits platform fines and forced promotions. Liability for certification and labeling sits with the seller, not the platform.
Does a Wildberries or Ozon seller need an online cash register under 54-FZ? For sales through the marketplace itself — no: Wildberries and Ozon accept the buyer's payment and form the receipt as the seller's agent, which is the standard scheme under 54-FZ. Your own register becomes necessary when you take payments directly: your own website, a retail store, cash on your own delivery. Self-employed sellers need no register in any case — the "Moy Nalog" app generates the receipts.
Is there an AI lawyer for a marketplace seller that checks requirements and labeling? Yes. Samreshuuu has a "Marketplace seller legal" expert skill: it checks whether a product is subject to mandatory certification and "Chestny ZNAK" labeling, tells you which document is needed (certificate, declaration, SGR or a rejection letter), helps choose a business form and tax regime, dissects platform offers and drafts claims over fines. In essence it is an online AI lawyer: you ask in plain language in the chat, and the skill activates itself. Know the boundary: this is consultation and document preparation, not a substitute for a lawyer in court.
What happens if you sell without a certificate or without labeling? Selling goods without a mandatory certificate or declaration triggers a fine under Art. 14.43 of the Administrative Code: 100,000–300,000 RUB for sole proprietors and 300,000–600,000 RUB for companies, up to 1M RUB with confiscation for repeat violations. Trading unlabeled goods costs 5,000–10,000 RUB for sole proprietors and 50,000–100,000 RUB for companies with confiscation, and at large scale it becomes criminal under Art. 171.1 of the Criminal Code. On top of that come the platforms' own sanctions: card blocking and deductions.
What does the marketplace law 289-FZ change for a seller? Phasing in from March 1, 2026: the platform must provide a full sales report with a breakdown of every deduction at least monthly, give 30 days' notice of changes to essential contract terms, may not fine for violations absent from the contract, and may not enroll goods in promotions without the seller's explicit consent. A mandatory pre-court dispute procedure with the platform appears. Sellers should log every forced promotion and watch how platforms bring their offers in line with the law — Samreshuuu can be given that monitoring as a scheduled task.
