Start with the bag, then check the listing’s claims. Number, registry, packaging — here is where to look.

ENplus: from bag to registry

  1. 1

    Find the number

    Ask for a bag photo from the pallet being offered. Look beside the ENplus mark for the class and ID, such as PL 004.

  2. 2

    Check the entry

    Search the producer or trader database for the full ID. Check the company and “Active” status.

  3. 3

    Match the product

    Open approved bag designs in the company profile. Match the brand, class, diameter and printing to the photo.

DINplus: a separate number and database

  1. Find the number

    Find the registration number beside the DINplus mark; for bulk pellets, look on the delivery documents.

  2. Check the entry

    Check the holder and validity date in DIN CERTCO. An ENplus number cannot replace it.

  3. Match the product

    The entry must cover wood pellets with the DINplus mark. Does the product name or model match the bag?

This records a registry lookup, not a pallet inspection. A missing result on Pelletnik does not prove forgery.

Three reasons to ask more

A mark without a number

Ask for a clear photo of the markings. An ENplus or DINplus logo alone is not enough.

Inactive or missing entry

Check the number for mistakes. Clarify the result with the certificate issuer before paying.

A different bag from the ENplus design

Compare the approved design. Someone else’s real number can be printed on a different bag.

ENplus blacklistAbsence from the list does not confirm legitimacy.
How to check a seller before paying
Buying from a reseller?

A shop selling bagged ENplus pellets need not hold its own certificate. The ID identifies the bag design owner, which may differ from the shop. Check the offered bag and its number.

A1, laboratory report, certificate — what is the difference?

A1 is a quality class, not evidence of certification or independent testing. A laboratory report covers the tested sample. Certification includes testing and production checks. ENplus documents forged certificates and misuse of its mark — check a seller’s PDF too.

ENplus: documents and misuse
Is certification enough to choose pellets for your boiler?

Check the manual for the required class and diameter. Certification does not replace these requirements; 6 mm and 8 mm pellets may not be interchangeable.
