Maryland EPR Registration Has Closed: What Producers Who Missed the Deadline Should Do Now

The May 31, 2026 deadline has passed
Maryland's packaging EPR program required covered producers to register by May 31, 2026. That deadline has closed. A separate July 1, 2026 milestone applied to Circular Action Alliance (CAA), which had to submit its producer list to the Maryland Department of the Environment (MDE) by that date; that was a PRO obligation, not a producer deadline. Producers who missed the May 31 registration are now non-compliant and should move quickly to limit enforcement exposure and prepare for annual data reporting.
This post covers late registration, what to file now, and the practical work to catch up.
Who is a producer in Maryland
Maryland's producer hierarchy follows the same pattern as other US programs:
1. The brand owner with US operations. 2. If no US brand owner, the importer of record. 3. If neither, the distributor or seller first placing goods on the Maryland market.
Marketplaces and online platforms can be deemed producers when no upstream entity qualifies. Small-producer thresholds apply; consult Maryland's current published rule before assuming exemption.
What Maryland covers
Maryland's covered material list includes packaging in all three layers and certain paper products. Producers should plan on Maryland scope being broadly comparable to Oregon and California, with Maryland-specific edge cases that should be confirmed against the current Department of the Environment guidance.
What the initial registration must include
The Maryland registration package generally requires:
1. Legal entity information for the registering producer. 2. Brand list covering all brands and product lines sold into Maryland. 3. Contact details for compliance, finance, and audit functions. 4. PRO membership confirmationCircular Action Alliance is the active PRO for most Maryland producers. 5. Initial covered-material data at the SKU or line level, with material category, weight, recyclability classification, and PCR content. 6. Indicative Maryland-bound volume for the upcoming reporting period.
Verify exact field-level requirements against the current Maryland Department of the Environment registration guidance.
A practical catch-up checklist for producers who missed May 31
The May 31, 2026 producer registration deadline has passed. For producers who did not register in time, the order of operations now is:
Immediately: Contact Circular Action Alliance (CAA) to open a late-registration file and notify MDE of intent to come into compliance. Document the outreach and any acknowledgments received.
Within 30 days: Complete CAA membership and submit the full registration package: legal entity, brand list, PRO membership confirmation, and initial covered-material data at the SKU or line level.
Ongoing: Track any late-registration penalties or enforcement notices from MDE, and align internally on fee accrual assumptions from the point fees begin to apply.
Before the next reporting cycle: Reconcile SKU-level packaging data to ERP shipment volumes into Maryland, and prepare the annual data submission on the schedule CAA and MDE publish.
Where producers most often slip
Three failure modes show up consistently in first-cycle US state registrations:
1. Wrong producer entity. The brand owner registers when the actual covered producer should be a different entity in the corporate structure. Fixing this after the fact is paperwork-intensive. 2. Brand list gaps. Smaller brands and private-label SKUs get missed in the initial brand list and have to be added in true-ups. 3. Material category misclassification. Internal terminology like "stand-up pouch" gets mapped to the wrong CAA category, which underprices the fee model and triggers reconciliation later.
The cure is the same as for every other state: clean SKU-level data, defensible state attribution, and an audit trail that holds up to a documentation request.
Multi-state context
If you are already registered with CAA for California, Colorado, Minnesota, Oregon, or Washington, Maryland is an extension of an existing membership rather than a fresh PRO setup. The data work is incremental, not duplicative.

How Packgine helps
Packgine prepares the Maryland registration package directly from your SKU-level packaging dataset, classifies materials to CAA's expected schema, runs internal reconciliation against ERP shipment data, and archives the submission with supporting evidence. The same dataset feeds California, Oregon, Colorado, Minnesota, Maine, and Washington.
