List of Certified Timber Suppliers and Treaters, abbreviated as CST is a special listing of selected suppliers and treaters of timber in particular sawntimber, who have succesfully complied with the requirements of a Quality Assurance Scheme (QAS) implemented by MTIB.

The QAS was established by MTIB in collaboration with FRIM following the aftermath of the JKR suspension on use of timber for roof trusses. One of the main concerns of JKR (and PAM as well) was with regard to the quality of timber that are supplied for construction projects in the domestic market.

An idea was mooted to establish a QAS and register suppliers and treaters who could comply with the requirement of the QAS. JKR, PAM and CIDB are committed to make a purchasing decision limiting to source timber that supplied by suppliers listed in the CST.

There are two categories involved in the QAS CST ie. Timber Suppliers and Timber Treaters.

Companies producing sawn timber can apply to be registered as Timber suppliers and those treating sawn timber (with treatment plant) can apply to be registered as Timber Treaters.

Application can be made at anytime by filling in the application form that can be downloaded from the MTIB website at http://www.mtib.gov.my or it can be obtained from Industry Development and Research Division, MTIB Kuala Lumpur. The application form is given free of charge.

The completed application form, together with the supporting documents, must be sent to the Industry Development and Research Division, MTIB Kuala Lumpur.
