Artificial drying / ISPM 15

Why do pallets need to be artificially dried?

There are several reasons for this:

  • Protecting stocks from the eventual presence of humidity (as soon as the products and their packaging show hydrophilic chrateristics),
  • Reducing  the weight of the pallets in order to facilitate handling
  • Improving the mechanical resistance and dimensional standards,
  • Limiting deterioration due to fungus and damages to the physical appearance of the pallets and crates.




Very often considered as a simple additional process, the drying of sawntimber and pallets requires however:

  • An in depth knowledge on the behavior of wood during the drying process,
  • An astute know how in the choice and manipulation of machinery


Our drying and thermal treatment facilities are among the best in France and are spread over several sites !

ISPM 15: international passport for exporting

The ISPM 15 (International Standard for Phytosanitary Measures) was ratified in 2002 in Rome by 115 countries. It defines the strict treatment standards to be implemented in order to avoid the spreading or dangerous organisms via wood packaging. Today, most of the world?s most important countries have decided to apply this where only intra community exchanges are not yet concerned.

There are two standards that are accepted: fumigation with a chemical agent (Methyl bromide) or by heating the core of the wood at 56°C for 30 minutes. In line with its commitment to Sustainable Development, the PGS Group advocates this process that is performed at its facilities with the double functions of thermal treatment and artificial heating. We pay very close attention to:

  • The calibration of our temperature sensors that guaranties the reliability of recordings,
  • The use of graphs and instructions of the Ministry of Agriculture and the FCBA,
  • The presence of an instructions manual at all our facilities
  • The use of labels that indicate the successful treatment in our ovens and dryers.
