Our Quality Control Practices

Receiving and Sampling

When we receive new raw material, we place it in quarantine – a clearly marked area separated from approved raw materials. Materials in this area are only handled by employees who gather samples for testing and cannot be used in production or sent to clients until all testing procedures and documentation is complete.

Any given shipment of raw material can contain several containers of the same product. To be sure all the material is up to our quality standards, samples are taken from every container. A composite sample is then blended from these samples and sent to a third party lab for analysis.

Each sample goes through several tests. Different products undergo different analyses based on the product’s chemical composition and properties. A product’s specification data sheet discloses which tests are performed and our minimum standards. These specifications are publicly posted for every product on the product listing page.
