An OCM transport inspection is a documentation audit, not a vehicle check. Inspectors verify four things: a METRC manifest that reconciles to every package in the cab, a current employee permit for everyone aboard, GPS and vehicle logs matching the manifest's route and timing, and a locked, unmarked cargo hold. Any package not tied to a manifest is a violation.
Why OCM Treats Transport as Its Own Inspection
Minnesota's Office of Cannabis Management regulates cannabis transport under Minn. Stat. ch. 342 — specifically sections 342.35 and 342.36 — and the administrative rules at Minn. Rules ch. 9810. The legislature built transport as a distinct license tier for a reason: cannabis moves between licensed facilities — cultivators, processors, manufacturers, retailers — and every handoff is a custody event with regulatory weight.
Transport is not incidental to the supply chain. It is the seam where product loss, diversion, and documentation failures are most likely to surface, because the product is in motion and off any one facility's premises. Inspectors audit transport accordingly. They are not looking for a clean truck. They are looking for systemic compliance — proof that nothing left a licensed facility that cannot be accounted for at the next one.
That distinction matters whether you operate the lane or hand it to a partner. If you are a cultivator, processor, manufacturer, or retailer receiving a delivery, your compliance posture depends partly on the documentation that arrives with the load. A manifest error on the inbound side can cloud your own METRC records the moment you accept it.
Emerald Enterprise & Distribution holds the licensed transport lane and is built to pass this inspection on every run. Here is what the inspector is checking, in the order it matters.
The METRC Manifest: The Single Most-Inspected Document
What inspectors want to see
Every cannabis transport in Minnesota must be covered by an active METRC transfer manifest generated before the vehicle departs. Inspectors verify:
- Package tag match. Each METRC package tag on a physical package in the vehicle corresponds exactly to a line item on the manifest. No extras, no omissions.
- Quantities and units. The weight, unit count, or volume on the manifest matches what is physically present. Discrepancies — even small ones — can trigger a Notice of Violation.
- Departure and arrival times. The manifest records planned departure and estimated arrival. Inspectors compare this against GPS and driver logs. A vehicle on the road two hours past its manifest window needs an explanation.
- Origin and destination license numbers. Both the sending and receiving facility's OCM license numbers must appear on the manifest, and inspectors confirm both are active at the time of transfer.
- Transfer status. On arrival, the receiving licensee must accept the transfer in METRC. Inspectors at the destination flag transfers sitting in "pending" past the regulatory window. An unaccepted transfer is an open chain-of-custody event.
Common manifest failures inspectors find
- Manifest generated after departure (timestamps are auditable in METRC)
- Package quantities changed mid-route with no documented correction and reason
- Rejected packages not returned to origin or properly documented as refused
- Transfers routed through a facility with no direct licensed relationship (unlicensed intermediary)
Transporter Licensing and Employee Permits
The transporter license itself
Under Minn. Stat. 342.35, any entity transporting cannabis between licensed facilities must hold an OCM cannabis transporter license. Inspectors verify the license is current, not suspended, and covers the vehicle in use. The license is facility-specific and vehicle-specific — a transporter cannot add a vehicle to a run without prior registration.
Employee transport agent permits
Every individual in a transport vehicle — driver and any accompanying agent — must hold a current OCM employee permit issued to the transporter licensee. Inspectors check:
- Permit holder's name matches the individual present
- Permit is active (not expired or revoked)
- Permit is tied to the correct employer license number
A driver operating under a borrowed or lapsed permit is among the most common personnel violations found at roadside. This is a strict-liability point: the permit is either valid or it is not.
Vehicle Requirements and Physical Security Controls
What the vehicle must have
OCM Rules ch. 9810 set physical requirements for cannabis transport vehicles. Inspectors look for:
- Locked, enclosed cargo area. Cannabis must ride in a compartment separate from the passenger cabin and secured with a lock. An open truck bed or unlocked cargo van does not meet the standard.
- No exterior cannabis markings. Vehicles must not advertise their cargo. Plain commercial livery is the standard.
- GPS tracking active and logged. The transporter must keep GPS records for every trip. Inspectors may request logs to reconcile against manifest timestamps. Gaps in GPS data — even brief ones — require documentation.
- Communication capability. The driver must have a way to reach the transport company and the receiving facility during the route.
Unauthorized stops
The route on the manifest is the route that gets driven. Inspectors cross-reference GPS data against the stated route. Stops not documented as pre-approved — fuel, mechanical emergency — are treated as custody breaks. A custody break without documentation is a chain-of-custody failure.
Chain-of-Custody Controls at Handoff
The handoff — when a driver transfers packages to a receiving facility — is a formal custody event under the METRC framework. When inspectors audit a receiving facility, they look at how that handoff was documented.
At the receiving facility
- The receiving employee must verify physical package tags against the manifest before accepting in METRC. Accepting a transfer without physical verification is a compliance failure at the destination.
- Damaged or discrepant packages must be refused or accepted with a noted variance. Accepting a damaged package without notation creates an unexplained inventory discrepancy downstream.
- The time of acceptance in METRC should align with actual delivery time. Back-dated acceptances are auditable.
At the sending facility
- The sending licensee's records must show the transfer was initiated from their licensed inventory. Inspectors trace packages back to source batches. A package that cannot be traced to a licensed grow or production batch is a red flag for diversion.
What Inspectors Are Really Assessing
Strip away the checklist and an OCM transport inspection answers one question: can every gram that left a licensed facility be accounted for at every point until it arrived at the next licensed facility?
Manifests, permits, GPS logs, and vehicle security are the evidence used to answer it. An operation with clean documentation answers fast. An operation with gaps forces the inspector to keep asking — which extends the inspection and raises the odds of a violation finding.
That is why documentation discipline is not a back-office task for a transport operation. It is the core of the service. A licensed transporter that treats the manifest, the permit, and the GPS log as the product is the one that keeps your inbound records clean.
What This Means for Operators Receiving Deliveries
If you are a dispensary, processor, or manufacturer taking cannabis from a transport partner, you have a direct stake in that partner's compliance posture:
- Verify the manifest before you accept the transfer. You are not obligated to accept a transfer with a manifest error. Accept it, and the discrepancy becomes your problem in METRC.
- Check the transporter's license. OCM maintains a public licensee search. Confirming your partner is actively licensed takes two minutes and closes a vendor-risk gap.
- Document your receiving process. Your receiving log — timestamp, employee, package count, noted variances — is your evidence of a clean handoff if a question arises later.
Your chain-of-custody compliance starts at the dock, not the shelf.
The One Thing to Take Away
An OCM transport inspection is a documentation audit. The inspector is not grading the truck or the driver — they are tracing a complete, accurate, time-stamped paper trail from the moment packages left the origin facility to the moment they reached yours. Build your transport operations, and your choice of transport partner, around that single standard.
FAQ
Does OCM announce transport inspections in advance?
No. OCM may conduct unannounced inspections of transport vehicles, origin facilities, and destination facilities. Roadside inspections by law enforcement coordinated with OCM are also possible. Your documentation must be current and in the vehicle at all times — not just when you expect a visit.
What happens if a METRC manifest has a quantity discrepancy?
A manifest discrepancy is a reportable event. The transporter must document the variance, the receiving facility must refuse it or note it on acceptance, and OCM must be notified per the reporting requirements in Minn. Rules ch. 9810. Unresolved discrepancies can result in a Notice of Violation against the transporter, the sender, or the receiver, depending on where the error originated.
Can a cultivator or processor use their own vehicle to transport product?
No. Under Minn. Stat. 342.35, only a licensed cannabis transporter may move cannabis between licensed facilities. A cultivator cannot use a company van to deliver to a retailer, even for a single run. The transport license is a separate license tier.
How long must transport records be retained?
Minnesota cannabis licensees are generally required to retain records for a minimum period specified under OCM Rules ch. 9810. Consult the current rule text or your compliance counsel for the exact retention window applicable to your license type, as rules may be updated through OCM rulemaking.
What is the difference between a METRC transfer and a METRC manifest?
In METRC, a "transfer" is the transaction record connecting two licensed facilities. The "manifest" is the document generated from that transfer, which must travel with the physical shipment. Inspectors want both: the METRC record confirming the transfer was created in the system, and the printed or digital manifest in the vehicle.
If a package is rejected at the destination, where does it go?
A rejected package must be returned to the origin facility under a new or amended METRC transfer manifest. It cannot be held at the destination or disposed of during transport. The return trip carries the same documentation requirements as the original delivery.
