The Departments of Revenue and Ecology have published a list of household products that are subject to the tax on hazardous substances. The list, compiled with the help of the Washington Retail Association and independent retailers, is intended to simplify tax reporting.

One of the most difficult problems in determining hazardous substance tax liability is identifying which substances are taxable. This is especially true in the case of hazardous substances packaged as household products, which are sold under a variety of tradenames.

The list makes it easy. If you sell any of the household products included in the list, then you owe hazardous substance tax unless your supplier or a prior possessor has paid the tax. If a household product is not included in the list, it is not subject to the tax.
