This page lists timber preservative formulations (by chemical class as a list of acceptable trade names) that the department has approved for use as biosecurity treatments as well as the minimum preservative retention requirement for each formulation.
The department accepts certain permanent preservative treatments as biosecurity treatments for use on certain timber products and timber packaging. To find out whether a product requires a treatment for biosecurity purposes, please check the department's Biosecurity Import Conditions system (BICON).
Exotic pests of timber include termites and insect borers such as beetles and wasps. These pests can arrive in timber and timber products as eggs or larvae. These pests may go unnoticed until frass (a sawdust-like substance produced by feeding wood boring insects) and holes appear or chewing sounds are heard.
It is critical to manage the risk of these pests. These pests may be harmful to our environment and economy if they enter Australia, spread, and become established.
