Why Test for Foreign Matter?

Foreign matter should not be present in a quality product.

Our scientists will inspect each lot of material under a microscope to determine the level of foreign matter, and a photograph will be included in your report.

What is Considered Foreign Matter?

Foreign matter is anything present in the material that is non-useable. This includes stems. The Nevada regulations place a limit of 5.0% stems 3 mm or more in diameter, and not more than 2.0% of other foreign matter.
