Your Freight Is Stuck at the Border: A Shipper Guide

Your truck has been parked at the border for three hours, your carrier says "it's in secondary," and your customer is calling asking why their delivery is late. A border hold can cost a shipper anywhere from a few hundred to several thousand dollars in detention and missed appointments, and most of it is avoidable once you know which of the handful of reasons is actually causing the delay.

Cross-border freight between Canada and the US clears through CBSA (Canada Border Services Agency) on the northbound side and CBP (US Customs and Border Protection) southbound. Both agencies have wide latitude to hold a shipment, and most holds trace back to paperwork, not the freight itself. The distinction matters practically: if the freight itself is the problem — a prohibited item, a misdeclared commodity — there's little you can do beyond working through the agency's process. But if it's a paperwork issue, which it usually is, the fix is often just a corrected document away.

Why is my freight actually stuck at the border?

• Missing or incomplete customs documentation. The most common cause by far — a commercial invoice missing required fields, an incorrect HS/HTS code, or a missing NAFTA/CUSMA certificate of origin when preferential tariff treatment is claimed.
• e-Manifest not filed or rejected. Carriers must submit an Advance Commercial Information (ACI) or Advance Cargo Information (ACE) manifest before arrival; a rejected or missing manifest stops the truck cold.
• Random or targeted secondary inspection. Some holds are simply routine compliance checks with no documentation problem at all — these typically resolve fastest since there's nothing to fix, just a queue to wait through.
• PGA (Partner Government Agency) requirements. Certain commodities — food, agricultural products, some consumer goods — require additional agency clearance (FDA, CFIA, USDA) beyond standard customs. If this clearance wasn't arranged before the truck left origin, expect the hold to last until the agency reviews and releases it, which can take considerably longer than a standard customs check.
• Carrier bond or compliance issue. If the carrier isn't C-TPAT/PIP certified or has a compliance flag on file, shipments can face more frequent secondary review.
• Weight or seal discrepancy. If the manifest weight doesn't match the scale reading, or a trailer seal number doesn't match what was declared, expect an automatic hold until it's reconciled.

Who do I call to find out what's actually wrong?

1. Your customs broker, first. They filed (or should have filed) the entry and can usually see the hold reason in their system within minutes — this is faster than waiting on the agency directly. If you don't have a broker relationship of your own and the carrier or dispatcher arranged customs clearance as part of the load, ask them for the broker's direct contact rather than relying on relayed information.
2. The carrier or driver, to confirm which lane and port they're held at, and whether they've been told anything by the officer on site.
3. CBSA or CBP directly, if your broker can't get an answer — both agencies have trade helplines, though response time varies by port and time of day.
4. Your dispatcher, if one is involved, to coordinate between the broker and carrier so you're not relaying information back and forth manually.

How long do border holds actually last?

Most holds resolve within a few hours to one business day. Random secondary inspections without an underlying documentation problem are often the fastest to clear — sometimes under two hours, depending on port volume and staffing that day. Documentation-driven holds take longer because they depend on how quickly your broker can correct and resubmit the paperwork, and PGA-related holds (FDA, CFIA, USDA) can stretch several days if the commodity requires additional agency sign-off that wasn't arranged in advance. Ports also see predictable slowdowns around peak holiday shipping periods and immediately after any regulatory change, so build extra buffer into cross-border schedules during those windows.

What can I do right now to speed up the release?

• Get the exact missing or incorrect document identified — don't guess. Ask your broker specifically what field or form triggered the hold.
• Send corrected paperwork electronically the moment you have it — most brokers can submit amendments without the truck needing to leave the port.
• Confirm the HS/HTS classification is correct — misclassification is one of the most common triggers for extended holds and can also generate penalties on top of the delay.
• Don't argue with the officer on site through the driver — work the paperwork fix through your broker instead. Secondary inspection decisions are made by the agency, not negotiated at the booth.

Getting the freight's value and description right on the underlying bill of lading also matters here — customs officers cross-check the commercial invoice against the BOL, and a mismatch between the two is a common trigger for extended holds. See our guide on how to read a bill of lading for what needs to line up.

How much is this delay actually costing me?

• Detention/demurrage: Most carrier contracts charge $50–$100+ per hour once free time (typically 1–2 hours) expires at the border.
• Missed delivery appointments: Retail DC violations can run $250–$5,000+ depending on the account.
• Penalties for classification or documentation errors: CBSA and CBP can assess monetary penalties separate from the delay itself if the underlying paperwork error is serious enough.

If a border delay causes real financial damage to your freight or blows a delivery deadline, know that the claims process for recovering those costs follows much the same documentation trail as any other freight claim — see how to file a freight claim in the USA for the paperwork you'll need.

Does the type of freight I'm shipping change the odds of a hold?

Yes, significantly. Certain commodities draw far more scrutiny than general freight:

• Food, beverage, and agricultural products almost always require additional PGA clearance (CFIA northbound, FDA/USDA southbound) and are among the most common causes of extended holds when that clearance wasn't arranged before the truck departed.
• Anything close to a hazmat classification gets extra scrutiny even when it's correctly documented as non-hazardous — be precise with commodity descriptions to avoid triggering an unnecessary review.
• High-value electronics and branded goods can trigger additional intellectual property or valuation checks, particularly on inbound shipments to the US.
• New commodities you haven't shipped before carry more risk simply because the HS/HTS classification and CUSMA eligibility haven't been tested and confirmed through a successful crossing yet.

If you regularly ship a commodity type that falls into any of these categories, it's worth setting up the required PGA paperwork and broker relationships as standing infrastructure, rather than scrambling to arrange it load by load.

How do I stop this from happening on the next cross-border load?

• Work with a customs broker who reviews documentation before the truck reaches the border, not after — pre-clearance review catches the mismatches that cause same-day holds.
• Confirm HS/HTS codes and CUSMA eligibility in advance for any new commodity you're shipping.
• Use carriers with C-TPAT/PIP or FAST program status where your volume justifies it — these programs meaningfully reduce secondary inspection frequency.
• Build a paperwork buffer into your schedule for cross-border loads rather than planning a same-day delivery window with zero margin for a hold.
