Submitting cannabis samples for testing in Minnesota is a multi-step process with specific requirements at every stage. Getting it right the first time prevents delays, lab intake rejections, and compliance gaps. For the complete testing transport framework, read The Complete Guide to Cannabis Testing Transport in Minnesota.
Step 1: Determine What Tests You Need
Confirm the required testing panels for your specific product type with your licensed testing lab before collecting samples. The lab’s intake team can tell you exactly which panels are mandatory under OCM rules for your product type.
Step 2: Collect Representative Samples
A representative sample accurately reflects the batch it came from. For flower, collect samples from multiple locations within the batch — not just from the top of one container. For manufactured products, samples should come from different points in the production run. Collect slightly more than the lab’s minimum requirement to allow for lab discretion.
Step 3: Package and Label Samples Correctly
Samples should be in sealed, clean containers appropriate to the product type. Labels should include at minimum: your facility’s Metrc license number, the batch or package ID the sample represents, the product type, the sample weight or quantity, and the date of collection.
Step 4: Create the Metrc Package and Transfer Manifest
Before the transport team arrives, create a Metrc package representing the sample — even small samples require a Metrc package entry. Then create a transfer manifest for the sample transfer, listing the sample package by its Metrc ID, the destination lab, and the expected transport window.
Step 5: Schedule Your Licensed Transport
Schedule your sample pickup with your licensed cannabis transporter. Confirm the pickup time, the destination lab, and whether any special handling requirements apply to your samples. Communicate same-day delivery constraints (lab cutoff times for intake) when scheduling.
Step 6: Complete the Pickup Handoff
Have a facility representative present at pickup. The transport team verifies the samples against the manifest, both parties sign the handoff documentation, and the samples are secured in the transport vehicle.
Step 7: Confirm Lab Intake
After transport, confirm with your transport partner or directly with the lab that samples were received and logged at intake. The Metrc manifest should close as received once the lab accepts the samples.
Step 8: Track the Certificate of Analysis
Most labs provide a portal where you can track your sample’s progress through their testing queue. When the COA is issued, review it before distributing the batch — confirm potency values match your labeled values within acceptable tolerance.
