In fact, everything is very simple.
Full verification is done through customs and fiscal documents, but there are obvious markers that help you quickly understand whether a device has been imported legally.

✅ Signs of legality:
• There are Ukrainian inscriptions or duplication in Ukrainian on the packaging and the device.
• Indicated importer and contact numbers.
• Inside — instructions in Ukrainian.
• There are complete details of the manufacturer and serial number / batch.
• The seller easily provides documents and information about the origin of the goods.

If all these points are present, you most likely have an officially imported device with full taxes paid.

🚫 Signs of risk:
• There are no Ukrainian inscriptions or they are made with violations.
• No importer information or contact details.
• There are no instructions in Ukrainian.
• Missing manufacturer details or serial number.
• The seller avoids questions about the documents, says "it's a commercial secret."
• The price is clearly lower than the market average for no objective reason.

⚠️ Consequences for retailers selling illegal devices:

Trade in products imported without paying taxes is smuggling.
Such goods are considered to be in violation of customs legislation.

The seller can expect:
• administrative responsibility — for violation of consumer packaging and labeling requirements;
• criminal liability — in case of large volumes of sales,
in particular, according to Art. 212 of the Criminal Code of Ukraine (tax evasion).

🎯 Legal products are not a formality,
it is the protection of business and consumers from fines, risks and reputational losses.
