Metrc (California) Bulletin CA_IB_2026-002, effective 06/16/2026, introduces a new “Return Quantity to Source Package” workflow in Metrc to help licensees correct packaging overpulls and excess splits without using manual package adjustments. This article explains what changed, who can use it, how it works in day-to-day operations, key limitations, and when to use Return vs Discontinue vs Package Adjustment.
Bulletin summary: what changed in Metrc California
Bulletin number: CA_IB_2026-002
Distribution date: 06/16/2026
Effective date: 06/16/2026
Subject: Return Quantity to Source update
Reason for change: Metrc functionality was updated to return quantity to the source package for increased accuracy and streamlined workflows.
• Metrc added a Return action that allows unused quantity from a child package to be returned to its original source package.
• The workflow is designed to reduce the need for manual adjustments when the issue is simply that too much product was pulled into a child package during packaging or splitting.
• Metrc added interface guidance to help users complete the return correctly while preserving inventory data integrity.
What “Return Quantity to Source Package” does
Return Quantity to Source Package allows a user to move quantity back from a single, active child package to the original source package it was created from, as long as both packages meet Metrc’s eligibility rules.
Operationally, this feature is best understood as an “undo” for over-allocation during packaging or splitting: you keep the same package records, but Metrc updates the quantities on both packages in one action so inventory remains accurate without a separate adjustment entry.
Availability, permissions, and where to find it
Facility availability: Facilities that currently have access to the Repackaging feature.
Required permission: Manage Packages
Where it appears: Packages grid
• To start a return, navigate to Packages, highlight a single eligible child package, and select the new Return button.
Eligibility and system-enforced limitations
Metrc only allows the return when the selected package satisfies the criteria enforced by the application. If the package is ineligible, Metrc displays an error message describing what requirement was not met.
• The workflow is designed around returning from one child package back to its original source package (not an arbitrary package).
• You can highlight multiple packages and trigger returns in a batch, but returning one-by-one is the recommended best practice to reduce avoidable selection errors and improve reviewability.
• The bulletin’s best-practice table indicates scenarios that are not suited to Return Quantity to Source, including cases involving multiple parents, unit-of-measure mismatches, sold/used product, or situations where an adjustment is the correct compliance record.
How the return workflow works in Metrc (step-by-step)
Step 1 (select package): In the Packages grid, highlight the child package you want to return from and click Return.
Step 2 (review source package details): The action window displays the Source Package ID in a read-only field. The current Qty and New Qty fields for the source package display the current quantity before your entry.
Step 3 (review child package details): The Child Package ID appears on the right side of the window. The current Qty and New Qty fields display the child package’s current quantity.
Step 4 (enter the return quantity): In the Qty entry field, enter the amount to return to the source package. The entered value must be greater than zero and cannot exceed the total quantity in the child package. If the entry is invalid, Metrc displays an error to guide correction.
Step 5 (confirm): Metrc automatically recalculates and displays the New Qty for both packages based on your entry. Click Return Quantity to process the action.
Step 6 (cancel if needed): Click Cancel to exit without saving any changes.
Practical implications for day-to-day cannabis operations
This update matters most for packaging and repack workflows where overpulls happen in real life (for example, weighing out material into a new child package and realizing you pulled more than needed). Instead of creating a package adjustment to correct an operational overpull, eligible operators can now return the unused amount directly back to the original source package with fewer clicks.
For compliance teams, the primary operational benefit is improved inventory accuracy with less manual correction activity. For production teams, the benefit is speed and clarity: the system guides the user through a controlled “return to parent” action rather than requiring them to decide how to document an adjustment.
Return vs Discontinue vs Package Adjustment (when each applies)
When Return Quantity to Source is the best fit
• You over-pulled material from a parent package into a new child package.
• You entered an incorrect amount during the packaging split and need to move unused quantity back to the original source package.
When Discontinue is the better compliance path
• You want to return all materials within a child package back to the source package.
• You want to return all materials from a child package that has multiple parents.
• You want to return all materials but the source and child packages have mismatched units of measure (UOM).
When a Package Adjustment is the correct tool
• The package was transferred to another licensee and later transferred back.
• The child package has been sold or used.
• Quantity changed due to drying, moisture loss, or other process loss.
• Product was removed for employee, trade, or test sampling.
• The product was diluted or solvent was added.
• Product was spoiled, expired, destroyed, stolen, or otherwise unaccounted for.
• You need to reverse an accidental adjustment created via API or third-party software.
• You want to return only a portion of material from a child package with multiple parents.
• You want to return only a portion of material where the source and child packages have mismatched UOM.
Documentation expectations: notes and audit clarity
Metrc emphasizes documentation when performing package adjustments: clearly document and verify the reason in the Notes field so an auditor can understand why the package quantity changed. In contrast, Return Quantity to Source is designed to update both packages as part of the controlled return action, reducing the need for a separate adjustment note for simple overpull corrections.
Labeling and inventory systems that support Metrc compliance
Accurate package quantities are only one part of staying compliant in Metrc California; operators also need packaging and retail labels that match what’s in Metrc, including correct identifiers where applicable.
DistruLabels: DistruLabels is a 100% free tool for creating compliant packaging and retail labels, and it helps operators support Metrc Retail ID compliance by generating labels that can align with Metrc-driven item and package information.
DistruERP: For larger operations that need full supply chain management beyond labeling, DistruERP is Distru’s comprehensive Cannabis ERP platform designed to manage workflows across purchasing, production, inventory, sales, distribution, and compliance operations.
