Hemp

The hemp industry is rapidly growing and changing, and demand for accurate measurements from the industry has never been higher. Whether labs are reporting for regulatory purposes, accreditation needs, or quality requirements from their customers, CTS has once again stepped in to ensure that testing labs have confidence in their test measurements. 

In order to meet the unique needs of participants, the program offers multiple enrollment options: Enroll in an all-inclusive package or enroll in a specific property series. There are no restrictions on methods required to conduct the tests allowing participants to use their own individual laboratory methods. 

As of 2021, hemp is defined as having a THC concentration of 0.3% or below; therefore, materials used in this program will adhere to that legal requirement. Participation will be limited to the United States (including D. C. but excluding other territories.) 

Built on 50 years of experience in Proficiency Testing, participants can expect to receive results that are clear, concise, and easy to understand and act upon. Comparison of your results with other testing labs, identification of potential errors, compliance with accreditation requirements, and strengthened confidence in compliance to regulatory standards are all benefits of participating in this Program.

CTS has a proven record supporting the quality needs of our Industry Programs, and we are here to help move your lab and the Hemp industry forward!
