Why marketplaces require certificates and declarations
Marketplaces act as intermediaries between sellers and buyers, but they are required to comply with product safety legislation. Requiring e-commerce businesses to provide a certificate or declaration is a way to reduce risks:
- sale of dangerous products;
- claims from regulatory authorities;
- consumer complaints.
For sellers, this means they need to prepare documents for selling on marketplaces in advance.
Mandatory certification: which goods require documentation
Not all products are subject to the same requirements, but mandatory certification or declaration is required for:
- electrical and electronic goods;
- children’s goods and toys;
- household appliances;
- cosmetics and personal hygiene products;
- light industry goods (certain categories);
- building materials.
It is these groups that most often need online product certification.
Rozetka’s requirements for seller certification
Rozetka requests certificates primarily for goods that fall under technical regulations. The platform can:
- require the upload of certificates or declarations;
- check the validity of documents;
- block product cards without confirmation of compliance.
For some categories, a declaration for online trading is the minimum acceptable document.
Requirements of Prom.ua and other platforms
Documents for Prom.ua are requested in a similar manner. The platform reserves the right to:
- hide product from search;
- suspend sales;
- block the seller’s account.
Other Ukrainian platforms also focus on marketplace requirements, even if they do not publicly state this.
The most popular product categories and their certification
Most often, certification for marketplaces is needed for:
- smartphones, accessories, chargers;
- kitchen and climate control equipment;
- children’s clothing and care products;
- cosmetics;
- home and repair goods.
The list of documents may vary for each category.
What documents to prepare for the marketplace
Depending on the product, you may need:
- certificate of conformity;
- declaration of conformity;
- test reports;
- technical documentation;
- markings and instructions in Ukrainian.
These documents form the basis for online product certification.
Where and how to obtain the necessary certificates
Documents are processed through accredited agencies. The process usually includes:
- analysis of goods and regulatory requirements;
- preparation of documentation;
- conducting tests (if necessary);
- issuing a certificate or declaration.
This is how you obtain a certificate for e-commerce that is acceptable for marketplaces.
Terms and cost of document processing
As of 2026, the indicative figures are as follows:
- terms — from 3–5 business days to 3–4 weeks;
- cost — from 5,000 to 30,000 UAH depending on the product.
The fastest way to get certified is for online commerce; the more complex procedure is for full certification.
Fines and blocking for lack of certificates
The absence of documents may result in:
- blocking of commodity items;
- sales stoppages;
- account deletion;
- penalties imposed by regulatory authorities.
That is why marketplace requirements should be met before sales begin.
Checklist before entering the marketplace
Before starting sales, check:
- whether certification is required for marketplaces in your specific category;
- whether up-to-date certificates or declarations have been prepared;
- does the name of the goods match the documents;
- has not expired;
- Are the documents ready to be uploaded to Rozetka or Prom.ua?
Selling on large online platforms is impossible without complying with product safety requirements. Online product certification protects not only consumers but also businesses from bans and fines. Preparing the right documents is an investment in stable sales on marketplaces, not an unnecessary formality.
