Plate for non fumigation tray plywood and OSB
Pallets used for export must meet quarantine treatment requirements. According to the internationally accepted Management Guidelines for Wood Packaging Materials for International Trade (ISPM15 * see the remarks), the quarantine treatment methods for wood packaging materials for export include

1. Heat treatment: The central temperature of wood shall be at least 56 ℃ for more than 30 minutes. Other methods can be regarded as heat treatment as long as they meet the requirements of heat treatment.

2. Methyl bromide fumigation treatment: the minimum fumigation temperature shall not be lower than 10 ℃, and the fumigation time shall not be less than 16 hours.

3. Enter other quarantine treatment methods approved by the country or region.

Plywood and oriented strand board (OSB) are wood-based panels formed by hot pressing (heat treatment) at high temperature (about 100 ℃~130 ℃), which meet the quarantine requirements of the Management Code for Wood Packaging Materials for International Trade (ISPM15) and can be directly used as wood packaging materials for export.

In fact, it can be concluded that plywood and OSB can be directly used as export packaging materials. The international trade volume of plywood and OSB is very huge every year. Plywood and OSB can be directly exported to all parts of the world for use as packaging materials for construction, furniture, decoration and importing countries. Since this is allowed, plywood and OSB can certainly be directly used as packaging materials for export. Moreover, pallets made of plywood and OSB are fumigation free.

If the pallet is made of solid wood, it must be fumigated and obtain relevant certificates before it can be used as wood packaging materials for export

OSB is the abbreviation of Oriented Strand Board. Its official Chinese name is Oriented Strand board, and it is also often called Ousong Board.

OSB is a kind of multilayer structural board formed by cross directional paving of long wood strips/chips, and then glue and hot pressing.

OSB is very different from density board and ordinary particle board. The density board is made of wood flour. Ordinary particle board is made of wood flour and small wood chips by irregular (non directional) pavement. Due to the difference of raw materials and production process, compared with density board and ordinary particle board, OSB has superior performance in strength, bearing capacity and stability.

Due to the use of glue with different properties, OSB can be used indoors or outdoors. According to the European standard of OSB BS EN 300, OSB can be divided into four categories:

OSB/1 - OSB for general use in dry environments (e.g. for indoor furniture)

OSB/2 - Load bearing oriented strand board in dry environment

OSB/3 – Oriented Particleboard for Load Bearing Applications in Wet Environments

OSB/4 – OSB for high load bearing applications in humid environments

In general, OSB is cheaper than plywood of similar quality. The raw materials (battens/chips) used for OSB come from cheap and abundant small diameter wood, while the raw materials (veneers) used for plywood come from relatively expensive large diameter wood. Under the general trend of increasingly scarce raw materials and rising prices, this outstanding advantage will promote the development of OSB more rapidly.

In many practical applications, OSB is a good substitute for plywood, such as furniture boards, roofing and floor paving materials, packaging, etc.

In recent years, the global sales of OSB have increased significantly. OSB has broad prospects for development.

The number of OSB produced, imported and exported in China is also increasing significantly.
