The story
Choosing who moves your Mexico freight comes down to three things: who owns each leg of the move, what they can prove about the carriers they put on it, and whether the rate they quote sits where the market actually is. A partner who can answer all three in writing, before the first load, is a partner you can build on. This guide is for shippers. If you are a broker choosing a platform, read How to choose a Mexico freight platform instead.
What does a Mexico move actually involve?
A truckload between the U.S. and Mexico is rarely one truck and one driver. Most moves have three legs: the Mexican leg, the border crossing and the U.S. leg. The crossing itself is often handled by a transfer carrier that only shuttles the trailer across the bridge. Some carriers run the whole route door to door with one trailer, and some hand off at the border.
Customs is separate from trucking. On the Mexican side, a licensed agente aduanal files the pedimento that clears your goods. On the U.S. side, a licensed U.S. customs broker files the entry for most importers. Most moves need both, and the agente aduanal often decides which bridge your freight uses, because they work at specific crossings. Your goods also travel with a Carta Porte on Mexican roads, which is why a good partner asks for truck, trailer and driver details before pickup.
Every partner you evaluate has to coordinate all of this. The question is how much of it they own directly.
Who can move your Mexico freight?
Asset carriers own the trucks. A Mexican carrier runs the Mexican leg and may or may not cross; a U.S. carrier runs the U.S. leg. Few own capacity on both sides of the border, so one carrier often covers one leg and subcontracts the rest.
Brokers and 3PLs own the coordination. They find and vet a carrier for each leg, hold the carrier contracts, line up the transfer and stay on the phone with the customs brokers. A 3PL may add warehousing or dedicated capacity. They own the outcome, not the trucks.
Freight forwarders own the international shipment end to end, and often coordinate the customs side through licensed customs brokers as well. A forwarder is common when your freight moves between Mexico and a third country, or when you want one party responsible for customs and transport together.
None of these is better by default. A shipper with steady lanes and an in-house logistics team may contract carriers directly. A shipper with variable volume, or with no Spanish-speaking staff, usually gets more from a broker or 3PL. What matters is that the partner can answer the questions below.
What should you ask any partner before the first load?
Eight questions separate a partner who knows Mexico from one who is learning on your freight.
- How do you vet the carriers you put on my freight? A Mexican carrier that does not cross the border has no MC or DOT number to look up. Ask what they check instead: the RFC and tax-status certificate, the SICT operating permit, the legal representative's identity, insurance and references, and how often they re-check. Ask them to name the carrier before dispatch and confirm it is the one that shows up at your dock, so double brokering has nowhere to hide.
- Which of your carriers hold CTPAT or OEA? CTPAT is the U.S. supply-chain security program and OEA is Mexico's. Both are voluntary, and the two programs recognize each other. If your own supply chain is certified, ask which legs of the move will run on certified carriers, and ask for the certificate, not a verbal yes.
- Will my freight cross through-trailer or transload? Through-trailer means the loaded trailer crosses intact. Transloading means the freight is unloaded at a border warehouse and reloaded into a different trailer. Every extra touch is a claims risk, and the choice changes the price. Ask which one they plan and why. Transloading vs through-trailer covers when each wins.
- How will I track the load? Ask how you get status on the Mexican leg, at the border and on the U.S. leg, and who you call when a trailer sits at the crossing.
- Who on your team speaks Spanish? The Mexican side of the move runs in Spanish. A partner who cannot talk to the Mexican carrier, the transfer and the agente aduanal in their language is relaying your problem through someone else.
- What are your cargo security rules? Ask about secured overnight parking, no-stop zones after pickup, GPS tracking and escorts for high-value commodities. A serious partner has written rules and can tell you which lanes need them.
- Who insures the load on the Mexican leg? Under Mexico's federal transport law, a carrier's liability is limited to a small statutory amount per ton unless the cargo value is declared and covered. In practice the cargo owner, the broker or the forwarder insures the full value. Get the answer in writing before dispatch. Cargo insurance in Mexico explains why.
- Where does your rate come from? Ask for the rate as a total per load, with fuel and the crossing included, and ask what it is benchmarked against. A partner who cannot show you where the market sits is asking you to trust the number.
How do you know a Mexico quote is fair?
A fair rate sits close to what carriers are actually bidding on that lane, for that trailer type, in the current market. Most U.S. rate tools have little or no data inside Mexico, so the benchmark has to come from carriers that actually bid on cross-border lanes.
Cargado publishes a market rate band for Mexico lanes: a low, a mid and a high, built from carrier bids on real postings over the last twelve weeks and refreshed every week. The middle half of recent bids sits between low and high, and mid is the median. Each band is a total per load, fuel included, in dollars, pesos or Canadian dollars, with a confidence label that tells you how much bidding stands behind it. A lane with too few recent bids shows no rate rather than a guess.
Compare like for like. The band is what carriers bid to move the freight, so a broker's or forwarder's quote sits above it by their margin and whatever services you bought. Read the gap, not just the number: under the low end, ask what is specific about that load; inside or just above the band, you are in line with the market; well over the high end, ask what is driving it, such as short notice, equipment or a lane that runs empty one way. Understanding rate data explains the percentiles, and How do I build a fuel surcharge for Mexico freight? covers why a U.S.-style fuel clause does not copy across the border.
Where does Cargado fit?
Cargado is a marketplace, not a freight broker, a carrier or a load board. Hundreds of brokers, 3PLs and freight forwarders post their Mexico and Canada freight on it and cover it with carriers our team has reviewed. Every carrier applies, and our team reviews the application before turning the account on: a U.S. carrier's USDOT number is looked up in FMCSA records and must show active authority, and a Mexican carrier submits its RFC, tax-status certificate, SICT permit, proof of address, legal representative's ID and company charter. Our team is alerted when a U.S. carrier's USDOT status is no longer active, and can restrict or deactivate a carrier. Brokers join on a subscription after meeting with our team. How Cargado vets carriers has the full list.
Shippers do not join the marketplace. If your partner covers your freight on Cargado, your loads are being offered to reviewed Mexico carriers, and your partner's own onboarding still decides who hauls them. What shippers use Cargado for is the rate data: subscribe directly, or reach the same benchmarks through partner platforms such as GoodShip, and go into every rate conversation with the market in front of you. Send us the Mexico lanes you are pricing and we will show you what the market looks like on them, and say plainly which lanes we have thin data on. See how shippers get Cargado rates, or talk to us.
