The short answer

Start from the freight's real dimensions, weight, loading method and temperature, not the commodity name, then check that the trailer works on both sides of the border. Ask whether the same trailer continues, whether equivalent equipment exists on the other side, and whether a transfer would change the loaded height or securement. For the general fit question, use the Freight Load Planner.

This page is part of the U.S.–Mexico Freight Shipping Guide. It covers the border-specific equipment questions; the trailer guide and equipment library cover trailer types in general.

How equipment decisions play out across the border

The trailer that leaves the U.S. shipper may not be the trailer that reaches the Mexican consignee. If the freight stays in one trailer, that trailer has to be accepted by every carrier in the chain and returned afterwards. If it is transloaded, the second trailer must fit the freight as well as the first did.

What the shipper needs

  • Longest, widest and tallest loaded dimensions
  • Total weight and the weight of the heaviest piece
  • Pallet or piece count and stackability
  • Loading direction and method: dock, forklift, crane or ground
  • Temperature range, if controlled
  • Tarp and securement needs

By equipment type

Dry van. Common for palletized or packaged freight loaded through the rear doors. Confirm the inside height and width and the door opening, not just the nominal trailer name, and whether the trailer continues across or is swapped.

Reefer. Add the set point, allowed range, pre-cooling, fuel plan, airflow and seal requirements. A long border wait can become a product-quality problem, and an open-dock transload is a temperature exposure. See reefer airflow and loading.

Flatbed and step deck. Width, loaded height, overhang, securement points, tarping and crane or forklift access all have to be known before quoting.

RGN and specialized. Machinery, transformers and other heavy indivisible freight may need low-deck or multi-axle equipment. Weight is not one number: axle configuration, deck height and center of gravity matter. See oversize and heavy-haul freight.

What changes the plan

  • Thinner reefer, step-deck and RGN capacity in many Mexican markets
  • A transload onto a trailer with a different deck height
  • Whether the freight can tolerate a transfer at all
  • Mexican carriers' own equipment standards and availability

Common failure points

  • Equipment chosen from the commodity name ("machinery") instead of measurements.
  • A tall load moved from a low deck to a higher one at the border, turning a legal load into an over-height one.
  • Assuming the Mexican trailer has the same interior dimensions as the U.S. one.
  • No forklift or crane at the transfer point.

Before requesting a quote

  • Loaded length, width and height
  • Total weight and heaviest piece
  • Pieces, pallets and stackability
  • Loading and unloading method at each end
  • Temperature range, if any
  • Tarp and securement needs
  • Whether transloading is allowed
  • Preferred trailer type, if known

Common questions

Can a U.S. trailer operate throughout Mexico?

Do not assume it can. Carrier arrangements, equipment ownership, registration, insurance and the operating model all need confirmation for the load.

Is a 53-foot dry van the same on both sides of the border?

Trailer families are similar, but interior dimensions, door openings, condition and usable capacity vary by unit. Measure against the actual trailer for tight loads.

Can FCC help if the trailer type is unknown?

Yes. Start with the dimensions, weight, packaging and loading method in the Freight Load Planner or the Equipment Selector, and send them with your quote request.

Match the trailer to the whole move

Send the freight measurements and loading details; we will price equipment that works on both sides of the border.
