Usually, importing countries make fumigation compulsory for solid wood / timber and logs . But importing countries don’t require fumigation for plywood, blockboard, MDF/HDF, OSB, hardboard, particle board and some other man-made boards . Why ?

Fumigation is a pesticide treatment using poisonous gases to kill pests within wood . The goal of fumigation is to protect forests from insects within the imported timber.

Solid timber and logs are probably have harmful living insects . It’s necessary to fumigate solid timer and logs before their entering importing countries’ markets. Otherwise, those harmful insects probably will cause great damage to the forests in importing countries .

But there won’t be living insects in some man-made boards such as plywood, blockboard, MDF/HDF, OSB, hardboard, particle board and so on. These man-made boards are produced under high temperature and high pressure . During production, all the insects in these man-made boards will be killed because of high temperature and high pressure .

Because of no insects, so these man-made boards won’t be required to be fumigated by importing countries .
