Obey CBP instructions. Filing acceptance does not guarantee release. CBP decides to release or examine the goods.
Road transport rules
Customs filing does not replace USDOT and motor carrier rules. Tell us if the trip is personal or for business. Send the weight ratings and the loaded weights of the truck and the trailer. In interstate or foreign commerce, a vehicle or combination with a weight rating or weight of 10,001 pounds or more can need a USDOT number (49 CFR 390.5, 390.201). Other rules can also apply.
Where do trucks cross at Sweetgrass?
| Side | Office | Commercial hours |
|---|---|---|
| United States (into Montana) | CBP port 3310, Sweetgrass, on Interstate 15 | 24 hours, 7 days a week |
| Canada (into Alberta) | CBSA Coutts office, on Highway 4 | 24 hours, 7 days a week |
A 24-hour crossing does not mean that Allied offers 24-hour filing service.
What is a PAPS number?
PAPS is the shipment number of the truck's ACE eManifest. The eManifest tells CBP about the truck, the driver and the cargo. The entry for the cargo refers to this number.
CBP must receive the eManifest at least 1 hour before the truck reaches the port. A shipment that qualifies for FAST processing has 30 minutes (19 CFR 123.92). Use the 1-hour period unless Allied confirms FAST for this trip.
These timing rules apply when CBP requires advance truck cargo information. Some informal entries are exempt under 19 CFR 123.92(b)(2): goods that are free of duty (unconditionally or conditionally) and worth $2,500 or less on CBP Form 7523, entries on CBP Form 368 or 368A, and U.S. goods returned on CBP Form 3311. Allied checks which filings your shipment needs before we quote.
The truck carrier is responsible for the eManifest. A driver without a carrier or SCAC can ask Allied for a same-day PAPS.
What goes wrong at Sweetgrass, and what should I do?
The eManifest is late
Send the request early. CBP needs the eManifest 1 hour before arrival, or 30 minutes for a shipment that qualifies for FAST processing.
The PAPS and the entry do not match
The entry must refer to the same shipment number as the eManifest. Give the driver the correct PAPS number before the truck leaves.
No customs bond
A formal entry needs a bond. We can buy a single entry bond for one shipment. See customs bonds.
A vehicle or a trailer is the cargo
Send the VIN, the ownership documents, the date of manufacture and the engine details before travel. NHTSA HS-7 box 1 needs a vehicle at least 25 years old from its date of manufacture. EPA code E on Form 3520-1 needs at least 21 years and the original configuration. A replaced engine must meet EPA rules. Heavy-duty highway engines use EPA Form 3520-21. A trailer that you import permanently is imported merchandise. Declare it, also when it carries other goods. It also needs a DOT HS-7 declaration and a safety compliance or exemption basis. Send its VIN, the ownership documents and photos of its certification label before travel. See vehicle imports and trailer imports.
