Manufactured articles, tobacco products, wood products are special exempted materials. This categorization typically pertains to tax laws where certain goods can be exempt from taxes under special circumstances, or they may be taxed at a special or reduced rate. For example, in some jurisdictions, there might be a tax exemption or reduced tax rate for wood products to promote the timber industry or for manufactured articles that are essential for economic growth.
