CERS Bulk Load Outage: Why Export Filing Downtime Matters for Drawback and Temporary Import Programs

CERS Bulk Load Outage: Why Export Filing Downtime Matters for Drawback and Temporary Import Programs

CBSA’s Canadian Export Reporting System (CERS) portal went down for bulk loads yesterday afternoon, 12:15 to 13:35 Eastern. Users trying to submit multiple B13A export declarations at once got kicked back with “CERS portal is unavailable.” Single filings worked. The issue lasted 80 minutes and was resolved.

Not an import clearance issue, but if you run a duty drawback program or manage temporary imports, export filing reliability is part of your compliance chain. You can’t recover duty on exported goods without a clean export record, and you can’t close out a temporary import without proof it left Canada. When CERS goes down during your export processing window, that 80 minutes can turn into a missed departure or a next-day refile.

What Bulk Loads Actually Do

CERS bulk load is how high-volume exporters and freight forwarders file dozens or hundreds of B13A declarations in one shot. A forwarder consolidating LTL export shipments on a single truck will batch the export declarations and upload them as a single file.

Single-shipment filers weren’t affected by yesterday’s outage. The issue was isolated to the bulk upload function. If you were filing one B13A at a time through the portal, you were fine.

The operational problem: bulk filers don’t typically have a fallback to single-entry filing when the bulk function drops. The volume is too high. If you’re a forwarder with 50 export shipments staging for a 3pm trailer departure and CERS bulk loads go down at 12:15, you’re not going to hand-key 50 separate B13As in 80 minutes. You hold the truck, or you push the shipments to tomorrow.

The Drawback Angle

Canadian importers who export finished goods or re-export unused imports rely on export records to support duty drawback claims under the Duty Drawback Program. You import components, pay customs duty and GST at the border, then export the finished product or the unused goods. The export proof is what lets you file for duty recovery.

The drawback claim needs a clean B13A with the right commodity codes, quantities, and values that tie back to your import CADs. If your forwarder’s bulk export filing gets delayed or botched because of a portal outage, and the export record doesn’t land in the system cleanly, your drawback claim documentation is incomplete.

We see this show up months later when an importer tries to file a drawback claim and CBSA kicks it back because the export quantities don’t reconcile, or the B13A commodity description doesn’t match the import HS code, or the export filing was amended three times and the audit trail is a mess. A lot of that traceability depends on getting the export filing right the first time, on time.

Temporary Imports and the Export Match Requirement

Temporary imports under Customs Tariff Item 9993.00.00 come into Canada duty-free or under a reduced-duty regime, with the condition that they’ll be re-exported within a set period (usually one year, extendable). Convention gear, trade show displays, samples, tooling, leased equipment.

When the temporary import period ends, CBSA expects proof the goods left Canada. That proof is the export B13A. If your temporary import bond is still open because the export record is missing or doesn’t match the import details, CBSA will assess the full duty you avoided on entry, plus interest.

A CERS outage that delays or disrupts your export filing can leave a temporary import case open longer than it should be. If the goods physically left on time but the B13A didn’t get filed because the bulk upload function was down, you’re now in a cleanup cycle: file the late export declaration, match it back to the temporary import record, explain the delay to CBSA, hope the bond doesn’t get called.

The 80-Minute Window and Real Impact

Yesterday’s outage ran 12:15 to 13:35 Eastern. That’s mid-day, which is when a lot of afternoon and evening export shipments are being processed. A truck departing at 3pm for a US border crossing needs its export filings done by early afternoon. An air export on a 6pm flight out of Pearson needs the B13A in the system before the cargo is tendered to the airline.

Eighty minutes is not a catastrophic delay if you have scheduling flexibility. It becomes a problem if you’re at the tail end of your filing window and you’re relying on bulk loads to clear a batch of shipments in one pass. The workaround: hold the shipments, or fall back to single-entry filing if the volume is manageable. Neither is ideal.

CBSA Portal Reliability and the CARM Parallel

CERS is the export side. CARM is the import side. Both are CBSA-managed portals that the trade community depends on for time-sensitive filings. When one goes down, even briefly, it highlights how much operational risk sits in portal uptime.

We’ve seen CARM Client Portal slowdowns during Statement of Account release windows, and we’ve seen eManifest submission queues back up during high-volume periods. Most of these issues get resolved within hours. But the underlying dependency is the same: if the portal is down and you’re in a filing window, you don’t have a lot of alternatives.

For importers, a CARM outage can delay release, trigger detention, or push a CAD filing past the due date. For exporters, a CERS outage can stop shipments from leaving. Both affect cash flow, customer commitments, and compliance timelines. If your operation involves both import and export, or if you’re managing drawback or temporary import programs that tie the two together, you’re exposed to downtime risk on both sides. That’s where having a customs broker who monitors these outages and can reroute filings or escalate with CBSA makes a difference.

What to Do When CERS Goes Down

If you’re mid-filing and CERS bulk loads drop:

• Check CBSA’s technical client notices (they usually post updates within 15-30 minutes of a known issue).
• Try a single-entry filing to confirm whether the outage is bulk-specific or portal-wide.
• If your shipment departure is time-critical and the outage persists, escalate with your broker or forwarder to see if there’s a manual filing path or a delay approval from CBSA.
• Document the outage and the delay, especially if it affects a temporary import deadline or a drawback claim timeline.

Most portal outages are short-lived. Yesterday’s 80-minute CERS bulk load issue is typical: annoying, disruptive for high-volume filers, but resolved before it caused widespread shipment holds. The real risk is when an outage hits during a high-stakes filing window and you don’t have a contingency.

If your export filing process is tangled up with drawback claims or temporary import tracking, and you’re not sure your documentation is clean enough to survive a CBSA audit, that’s the kind of compliance review we run routinely. Get in touch.
