On December 14, 2018, a policy statement on how the Washington state department of agriculture will determine if a 0.003 THC test result exceeds the regulatory limit for industrial hemp was signed. The federal and Washington state statutory standard for the allowed level of THC in a tested sample of industrial hemp is silent on whether or how to interpret a test result beyond the three decimal (thousandths) place represented by the "0.3 percent" significant figure standard. This policy statement is intended to provide a "significant figure rounding" convention when an isolated or aggregated THC test result is .003 and the reported test result extends beyond the first three decimal places (up to three additional decimal places). Applying significant figure rounding can determine whether a .003 test result meets the "not more than 0.3 percent" (federal law) or "0.3 percent (THC) or less" (state law) significant figure standard.
