Documents required before dispatch
Every one of these should exist and agree with the others before a truck is assigned.
- Commercial invoice with accurate values, currency and terms of sale
- Detailed packing list matching piece count and weights
- Bill of lading with correct shipper, consignee and references
- Customs broker name and contact for the importing country
- PARS or PAPS arrangement confirmed with that broker
- Certificates of origin or permits where the commodity requires them
The four errors that cause most delays
- Vague commodity descriptions — 'parts' or 'samples' invites inspection
- Values or piece counts that differ between invoice and packing list
- Broker not notified in advance, so nothing is filed when the truck arrives
- Missing HS codes or an incorrect country of origin
Who does what
The shipper produces accurate commercial documents. The customs broker files entry with the importing authority. The carrier presents the shipment and paperwork at the crossing. Cantrans is not a licensed customs broker — we coordinate with the broker you appoint.
Planning realistic timing
Treat border processing as a variable, not a constant. Long weekends, holiday periods and inspection referrals can turn a same-day lane into a next-day one. Build a buffer into any commitment you make to your customer.
