Specifications, Testing and Certificates of Analysis

Trade buyers judge refined hemp oil on paper before they judge it in a tank. This section is for anyone who has to read a certificate of analysis and know whether a lot is acceptable: free fatty acid content, peroxide value, moisture, colour, iodine value as an identity check, and the food-grade, organic or kosher certifications a customer may require. It also covers what rising numbers signal about age and handling, and how to write a purchase specification.
