Pre-Harvest Sampling and Testing for THC

To request sampling and testing a grower must submit a sampling request form provided by the Oregon Department of Agriculture that includes: 

(a) A written sampling request for THC analysis for each harvest lot, as identified by the harvest lot identifier, for which the grower is requesting sampling and testing and the total number of harvest lots to be sampled and tested; 

(b) A description of the location of the production area of each harvest lot, as identified by the harvest lot identifier, including the GPS coordinates or address of the harvest lot; and 

(c) A written description and visual depiction of each harvest lot to be sampled and tested such that the production area for each harvest lot is apparent from a visual inspection of the premises and easily discernible from other harvest lots. 

As of January 1, 2022 sampling of the harvest lot must occur not more than thirty (30) days prior to harvest. Harvest must be complete within the applicable time period for sampling or the grower must arrange for additional sampling of the unharvested cannabis in accordance with these rules. 

If a purpose of the harvest lot is to produce flower, the grower must arrange for sampling such that flowers are present at the time of sampling. In this case, only plants with flowers shall be sampled. 

The grower or authorized representative must provide the sampler with unrestricted and unobstructed access to all hemp and other cannabis plants whether growing or harvested and all lands, buildings, and other structures used for cultivation, handling, and storage of all hemp and Cannabis and all other locations listed in the grower’s license. 

During a scheduled sampling, the grower, person in charge of the grow site, or an authorized representative of the grower shall be present at the grow site.
