Stacked shipping containers awaiting customs release — the paperwork side of cross-border freight
Free shipper guide · Used on every Qeep cross-border load

PARS, PAPS and the
cross-border checklist.

Border delays are almost never caused by the border — they’re caused by paperwork that left the dock late or didn’t match the freight. Here’s the checklist that prevents them, free to use whether you ship with us or not.

The two barcodes

PARS vs PAPS,
in one minute.

Mirror images of the same idea: customs reviews the paperwork beforethe truck arrives. If the barcode isn’t set up when the driver reaches the booth, the truck waits — that’s the whole game.

PAPS

The document checklist

Eight documents. Zero surprises.

Every item, who owns it, and the mistake that turns it into a border sit.

Commercial invoice / CCI

Shipper

Buyer, seller, precise goods description, value, currency, origin — must match the physical freight exactly.

Bill of lading

Shipper + carrier

Piece counts and weights that agree with the invoice. Mismatches are exam bait.

PARS / PAPS barcode

Carrier

On the paperwork sent to the broker hours before the truck reaches the border — not minutes.

ACE / ACI e-manifest

Carrier

Filed at least one hour before arrival. ACE into the US, ACI into Canada.

CUSMA/USMCA certificate

Shipper

Only when claiming duty-free — but claiming without it is a classic hold.

Permits / PGA-OGD docs

Shipper + broker

Food (CFIA/FDA), plants, chemicals and other regulated goods carry extra requirements.

CARM registration

Importer

Imports into Canada: importer registered with financial security posted before freight moves.

Customs entry

Customs broker

Filed with CBP or CBSA against the PAPS/PARS number, pre-arrival.

The failure modes

What actually delays trucks at the border.

01

Late paperwork

The #1 cause of border sits: documents that reach the broker after the truck is already rolling.

02

Invoice mismatches

Counts, weights or descriptions that don't match the load — an invitation to secondary inspection.

03

Missing CUSMA cert

Claiming duty-free without the certificate on file. Either have it or don't claim it.

04

E-manifest errors

Wrong port code, wrong trip number, filed late — small typos with hour-long consequences.

05

CARM gaps

Importers not registered or without security posted. The freight physically cannot clear.

06

Nobody watching

A fixable hold that sits all weekend because no one was tracking border status. We watch ours hourly.

Who does what on a Qeep cross-border load

You handle the invoice, CUSMA cert and CARM. Your customs broker files entries. The carrier runs barcodes and e-manifests. Qeep orchestrates all three — paperwork chased to the broker before pickup, border status watched live, holds escalated the hour they appear. Details on our cross-border service.

Frequently asked questions

Cross-border paperwork, answered.

What is the difference between PARS and PAPS?

They're mirror images. PARS (Pre-Arrival Review System) is Canada's program: the barcode and paperwork that let CBSA review a shipment BEFORE the truck reaches the Canadian border. PAPS (Pre-Arrival Processing System) is the US equivalent: the barcode that lets US CBP pre-process a shipment before the truck arrives at the US border. Southbound loads use PAPS; northbound loads use PARS.

What documents does a Canada–US truck shipment need?

At minimum: a commercial invoice (or Canada Customs Invoice northbound), a bill of lading, the PARS/PAPS barcode on the paperwork sent to the customs broker, an ACE e-manifest (into the US) or ACI e-manifest (into Canada) filed by the carrier, and a CUSMA/USMCA certificate of origin if duty-free treatment is claimed. Specific goods can need permits or PGA/OGD documents.

What is CARM and does it affect my shipments into Canada?

CARM is CBSA's system for assessing and collecting duties and taxes on commercial imports into Canada. Importers need their own CARM registration and financial security — responsibilities that used to ride on the customs broker's bond. If you import into Canada, confirm your CARM registration and security are in place before freight moves.

Does Qeep clear customs for me?

We're not a customs broker — and we're honest about that. We coordinate tightly with YOUR customs broker: paperwork moves to them before the truck moves, PARS/PAPS numbers are communicated properly, e-manifests are filed, and border status is watched so a hold never sits unnoticed. If you don't have a broker, we can point you to ones we work with daily.

What usually delays trucks at the border?

The same short list, over and over: paperwork sent to the broker late (the #1 cause), invoice details that don't match the load, missing CUSMA certificates when duty-free is claimed, e-manifest errors, and importers not set up in CARM. Almost every border delay is preventable before the truck leaves the dock.
