  • Water content
  • Bulk density
  • Mechanical strength
  • Chemical contamination

In addition, we also determine what is referred to as the ash melting temperature. This temperature is important in estimating the tendency to generate slag.

The most important questions and answers about wood pellet certification

Do you want to know more about our wood pellet testing and certification services? We have compiled the most frequently asked questions for you below.

  • 1. What requirements must be met for DINplus certification?
    • Requirements for wood pellets for  DINplus certification

      DINplus certification shows that your work is of the highest quality, that you offer consistently high product quality levels, and that you voluntarily submit to regular monitoring. Your products must meet the following requirements (see graphic).

      If the assessment by DIN CERTCO is successful, you will receive a five-year certificate.

  • 2. What advantages does DINplus certification offer manufacturers, retailers and consumers?
    • We have been developing quality standards for many years as a reliable companion to the pellet industry and have earned the trust of manufacturers, sellers and consumers. DINplus certification is also mentioned in the 1st German Federal Immission Control Ordinance, a fact that underlines how accepted this certification is.

      The DIN plus certificate allows manufacturers and sellers to demonstrate that they are reliable and provide a consistent quality level that meets consumer expectations.

  • 3. What do I need to know about packaging?
  • 4. What points must sellers observe?
    • Fuel sellers and wood pellet suppliers frequently sell their products under their own name without specifying the original pellet producer. Such wood pellets can naturally be marked DINplus as well. To do so, you as the seller need a sub-license, which you can request from our experts in writing. You need the approval of the manufacturer to do so.

      If the wood pellet manufacturer already has a DINplus certificate, you can request a certificate via that manufacturer, which will then be issued in the name of the seller or supplier. This certificate depends on the manufacturer's certification in all its aspects.

  • 5. How much does DINplus certification cost?
    • The cost of the certification procedure is mainly dependent on the location of the production site requiring certification. Certification costs can therefore vary widely.

      Certification for a production site in Germany usually costs between €3,000 and €4,000 a year. We will of course be happy to prepare a detailed non-binding quote on certification cost for any interested company.

  • 6. How do I know which wood pellets meet DINplus requirements?
    • Every successfully certified manufacturer of DINplus wood pellets receives a certificate from us that customers can ask to see at any time. The wood pellet packaging also features the DINplus quality mark with the corresponding registration number. If the pellets are delivered without packaging, the mark with the registration number is shown on the delivery notes.
