All of our sites are PEFC-certified. Only products from PEFC-certified forests and following an uninterrupted chain of certified manufacturing and distribution companies can claim the PEFC label. On a wooden or wood-based product (including paper and cardboard), the PEFC label certifies:

  • that the forest owner that grew the trees and the forestry company that harvested and transported the wood implemented PEFC sustainable forestry management practices;
  • that all the companies involved in the transformation and sale of this wood applied PEFC traceability rules;

The PEFC label thus guarantees consumers that the product they are buying comes from responsible sources and that the purchase contributes to the sustainable management of forests. Sustainable management of a forest means consideration of environmental, social and economic aspects.

Monnet-Sève Sougy has the CE mark for its various production sites. The CE mark was created for the European technical harmonization legislation. It is a visible sign from the manufacturer that its products comply with the regulatory requirements that enable free movement throughout the European Union. The CE mark on products is the result of a procedure to assess the compliance of these products with the essential requirements defined by the applicable Directives and Regulations (in this case, the Construction Products Regulation – CPR).

At its various sites, our group has multi-dimensional measurement equipment, more commonly known as scalers, that are used when the logs first arrive. These tools enable measurement of the exact volumes received. This information is compared with our production data and output volumes to produce performance analyses. The CTB Roundwood Volume Measurement certification therefore enables clarification of the measurement of the volumes of wood processed by our sites, because it is being based on rules developed by and shared throughout the industry. This certification involves an independent third party audit by FCBA.

All of our sites have this certification. It was introduced in June 2003 following the merger of CTB Sawn Timber and CTB Hardwoods to cover both hardwood and softwood sawn timber. Production inspections are carried out by FCBA, an independent body, certified by COFRAC for the “CERTIFICATION OF PRODUCTS AND SERVICES”. This certification is based on a reference system that serves as a working and communication tool. 6 French and European standards are used as references by CTB Sawn Timber. These are the main properties certified:

  • Standardized mechanical or appearance visual grading;
  • Respect of “rough sawn” or “dry wood” dimensions with standardized tolerances;
  • dry wood humidity level;
  • Suitable packaging;

In 1996, WCLIB became the first American grading organization to help European construction timber producers to enter the American markets and, over the following 22 years, WCLIB defined American design values for European species, trained grading technicians and helped European sawmills to develop their activities in the USA. In 2019, the Pacific Lumber Inspection Bureau (PLIB) and the West Coast Lumber Inspection Bureau (WCLIB) merged their activities. Although the company name was changed to PLIB, the WCLIB brand is still recognized and European members continue to receive the best quality inspection services in their category, uninterrupted support regardless of market conditions and unrivaled assistance with selling on American markets.
