ENplus® has published second editions of ST 1001 and ST 1003 standards
We would like to announce the release of the second editions of the ENplus® ST 1001 and ENplus® ST 1003 documents, marking a step forward in the continuous improvement of the ENplus® certification scheme and its key role in the pellet market.
These updated standards reflect our commitment to deliver more clarity, better consistency, and optimised efficiency when it comes to the needs of certified companies. The changes are rather minor, and companies have until the end of 2025 to comply with them during a three-month transition period. 1 January 2026 is the entry-into-force date for the second editions, which were published on 1 October 2025.
The new editions of the documents introduces refined definitions for trademark use, producers, and bulk pellet trade, along with updated normative references.
The second edition of ENplus® ST 1001 presents structural changes that define requirements for multisite companies and clarify outsourcing agreements, especially for the cases involving non-certified service providers. Technical enhancements detail calibration protocols for measuring devices, and refine procedures for big bag filling and self-monitoring.
The product requirements for traders with bagging activities have been simplified, as these companies will no longer need to ensure mechanical durability compliance.
Delivery documentation has been streamlined, with clearer distinctions between producer and trader responsibilities. Finally, updates to complaint management and reference sample handling, along with revised tables and visuals, round out a more robust and user-friendly standard.
The revised ENplus® ST 1003 introduces a range of targeted updates aimed at improving the precision and usability of the standard. Notably, the definitions of key terms such as producer, on-product use of trademarks, and bulk pellet trade without physical contact have been clarified to eliminate ambiguity.
Provisions related to trademark usage—especially concerning logo placement, bag design permissions, and translation requirements—have been revised to better support consistent branding and international communication.
Even though the new editions of the standards do not introduce major changes, we encourage all stakeholders to review the updated documents here and adapt their operations accordingly. A detailed look of the changes is also provided in the comparison documents – Changes of ST 1001 and Changes of ST 1003.
