Why is a lot of significance attached to heat-treated wood when it comes to export packing? This is because when wooden packaging is moved from one place to another and travels long distances; there arise problems of mold, bacteria, and fungi. It is the inherent property of both softwood and hardwood to create such problems despite its sturdy character.
These problems do not just affect the package but also its contents since they run a high risk of contamination and deterioration.

Therefore, the International Plant Protection Committee stipulates wood treatment before they can be used to pack goods and products. This standard is largely referred to as ISPM 15 standard and an increasing number of countries prescribe to this regulation.
Chemical vs. Heat Treatment
Not too long ago, in export packing, only chemically treated wood was being used. Stronger chemicals and preservatives characterized chemical treatment. However, changes made to the regulation as of March 2002 stipulate the need for the heat treatment of wooden pallets, cases, and crates.
There are distinct differences between the two besides the nature of the treatment. Heat-treated pallets are considered to be a safe and better choice because it is
1. Environment friendly, unlike strict chemical treatment.
2. Hazardous to people who come in contact with the pack since the pallets are devoid of chemicals.
Heat treatment of pallets to 56 degrees Centigrade for 30 minutes is what export packaging specifications prescribe in order to obtain a compliance stamp. Heat treatment is offered by a hand-picked lot of vendors at the client site for increased flexibility and resource efficiency.
