Metrc Users' Guide
Tags for Samples
Testing samples sent to labs MUST have the Metrc package tag affixed to the container/product. This applies to
both the primary and reserve testing samples.
Virtual Transfers
OMMA will not grant permission for virtual transfers prohibited in our rules or state laws. We are unable to make
exceptions for errors or mistakes like accepting delivery in Metrc before physical delivery and or accepting a
delivery with missing or damaged products either digitally (in Metrc) or physically. It’s important to check the
entire delivery for accuracy before accepting it in Metrc and physically. Licensees must accept or reject each
package on a manifest in its entirety – you can’t accept only part of a package.
When a product is missing or in similar cases when a licensee chooses to refuse a delivery, the licensee must
refuse the entire package on the delivery manifest and return the products with proper documentation on the
physical and digital manifests. Licensees cannot accept only part of a package.
If your company’s physical and digital inventory do not match after a transfer has already been completed and
you have product on hand that is unaccounted for in Metrc, please fill out the contact form at
omma.ok.gov/contact and select “Seed-to-Sale (Metrc)” in the field for “Regarding.”
Compliance
Being credentialed in Metrc and using it to track your inventory is required by state law and OMMA rules.
Licensees are responsible for ensuring all information and actions in Metrc are also compliant with OMMA rules
and state law – Metrc is a tracking system, not a compliance tool, and some actions or information allowed in
Metrc may not be compliant. You may consider seeking legal advice if you’re unsure about compliance
requirements.
Re-Testing
OMMA rules allow re-testing of products only for failures that allow a product to be decontaminated or
remediated.
Products with failures for heavy metals, pesticides or mycotoxins can’t be remediated or decontaminated and
must be legally disposed of as waste. Products may also not be re-tested for potency. Licensees may not take
products that have already been tested to a second lab for a new test – it’s commonly referred to as “lab
shopping,” and it’s against OMMA Rules.
Item Categories
Metrc and OMMA compiled tables to help licensees determine which Metrc product categories to select for
different products or stages of production, and the required testing. The production stages and products
include finished plant material, concentrates/extracts and infused products.
Please review Metrc Bulletin 19 in the Appendix for details.
Plant Waste
There are different procedures within Metrc to properly designate material as waste. Metrc compiled guidance
on how to create waste items, create waste packages for different types of plant material, clone waste packages
and transferring waste packages.
Please review Metrc Bulletin 10 in the Appendix for details.
