How to Read a Customs Broker Quote in Mexico: Fees, DTA, Pre-Validation and the Line Items That Show Up Later

The quote arrives on a single sheet. Broker fees, a percentage or a flat rate per operation, pre-validation, DTA, cargo handling, "payments on the client's behalf," and a total. The CFO approves it because the total fits the shipment budget. Six weeks later the expense statement arrives with nine line items where the quote had five. The four new ones were already provided for in the law or in the bonded facility's tariff, and none of them was on the sheet, because the sheet quoted the clearance and the expense statement bills the shipment.

That is the distance this piece closes. A customs broker quote in Mexico mixes three things of a different nature: the service the broker charges for its own work, the contributions the broker pays to the treasury on the company's behalf, and the third-party services the broker contracts and re-invoices. Reading it line by line means knowing which of the three each item is, who sets its amount, and which ones depend on what happens at the port of entry on crossing day. With the 2026 rates in front of you, the exercise takes twenty minutes and spares the uncomfortable conversation over the final invoice.

Three columns: broker services, payments on the client's behalf, and third-party services

The first reading of any quote consists of separating each item according to who receives the money.

In the first column are the customs broker's services: fees, processing, preparation and filing of the pedimento (Mexico's customs entry), tariff classification, document review. This is the only group whose amount the broker sets. It carries 16 percent VAT and is invoiced with a CFDI, Mexico's digital tax invoice, in the company's name.

In the second column are the payments on the client's behalf: the General Import Duty (IGI), import VAT, the Customs Processing Fee (DTA), pre-validation, and antidumping or countervailing duties where they apply. The broker sets none of these amounts. The law determines them, they are declared on the pedimento, and they are paid to the Federal Treasury (Tesorería de la Federación). The broker advances or manages them, and Article 53 of the Ley Aduanera, Mexico's customs law, makes the broker jointly liable for their payment, which is why no broker clears a shipment without confirmed funds or a confirmed payment instruction.

In the third column are the third-party services: cargo handling and storage at the bonded facility, bill of lading release at the ocean carrier, freight and border crossing with the carrier, inspection services when a regulation requires them. The broker contracts or coordinates them and either re-invoices them or pays them on the company's behalf.

A well-built quote presents the three columns separately and marks which items are estimates. A quote compressed into a single list with a total at the bottom forces the reader to make that separation alone, and that is the CFO's first job before signing.

Broker fees: the only line the broker sets

Customs broker fees in Mexico are freely negotiated. No official tariff has set them in decades, which is why a quote presents them in one of three forms: a percentage of the value of the goods, a flat rate per pedimento, or a combination of both with a minimum per operation. Each form has its logic. The percentage follows the risk the broker assumes as a jointly liable party on high-value shipments; the flat rate follows repetitive low-value operations where the documentary work is the same shipment after shipment; the minimum protects the broker on small operations that cost the same in hours as a large one.

What deserves a careful reading on this line are the conditions, because that is where the items the sheet did not show appear later. Three questions resolve almost everything: whether the fee covers a pedimento with one tariff line or each additional tariff line is charged separately; whether it covers a standard pedimento or the consolidated entry, the supplementary entry and the amended entry each carry their own rate; and whether it includes tariff classification of new merchandise or that is a separate advisory item. Across our more than 190,000 customs operations a year at 39 ports, most of the differences between quote and expense statement under broker fees originate in those three questions.

Broker fees carry 16 percent VAT, which the company can credit. That is the only part of the operation's VAT calculated on a service. The rest of the VAT, the one on the import itself, is calculated on a different base and sits in the second column.

The contributions that travel on the pedimento: DTA, pre-validation and the settlement box

Everything the company pays the treasury for the shipment is written in a single place: the pedimento's settlement box, the cuadro de liquidación. That box is the document against which the second column of the quote is verified, item by item. If you have already read our guide on how to read a Mexican pedimento field by field, you know where that block sits. What matters here is what it says and who sets each figure.

The General Import Duty depends on the tariff classification and on origin. It can be zero under the USMCA or an equivalent agreement with the certification of origin in order, and it can be the general rate of the tariff schedule without it. A quote that does not ask about the origin of the goods and the available proof is quoting the duty blind.

The Customs Processing Fee is the item that generates the most confusion and the one that should generate the least. It is set by Article 49 of the Ley Federal de Derechos, Mexico's federal fees law, and for 2026 its rates were updated in Anexo 4 of the Resolución Miscelánea Fiscal for 2026, published in the Diario Oficial de la Federación on December 28, 2025. The 2026 reading is as follows. The general rate is 8 per thousand of the customs value, or 0.8 percent: a shipment worth one million pesos pays 8,000 pesos of DTA. Temporary import of fixed assets under IMMEX pays 1.76 per thousand. Temporary import of inputs under IMMEX pays a flat 462 pesos per operation, and that same 462-peso rate applies to imports covered by agreements that prohibit charges on the value of the goods, such as those with the European Union, the European Free Trade Association, the United Kingdom, Israel and the CPTPP countries. Exports pay 463 pesos. Each amended entry pays 444 pesos. And there is a floor: when 8 per thousand or 1.76 per thousand yields less than 462 pesos, 462 is paid.

For goods originating under the USMCA, rule 5.1.4 of the Reglas Generales de Comercio Exterior for 2026, the RGCE, waives the DTA on permanent imports, temporary imports and returns. A CFO importing components from the United States with a valid certification of origin should see zero on the DTA line. If the line shows 8 per thousand, the right question goes to the certification of origin.

Electronic pre-validation is a separate item from the DTA and appears separately. It is required by Article 16-A of the Ley Aduanera: before the pedimento is transmitted to the customs electronic system, an authorized pre-validator checks that the data meets SAT's syntactic, catalog, structural and regulatory criteria. For 2026, RGCE rule 1.8.3 set the pre-validation charge at 350 pesos per pedimento, plus VAT. It is a fixed amount per pedimento, independent of value, and it is declared in the settlement box under its own code. The quote should show it as a payment on the client's behalf, with VAT, and never inside the broker fees.

Import VAT has a base that tends to surprise. Under Article 27 of the Ley del Impuesto al Valor Agregado, Mexico's VAT law, the VAT base on imports is the value used for the General Import Duty, plus the amount of that duty and of the other contributions and charges payable on the import. In practical terms: the DTA and any antidumping or countervailing duties enter the VAT base. A DTA of 8,000 pesos generates a further 1,280 pesos of VAT. A quote that calculates VAT on the commercial invoice value falls short on every shipment, and the difference shows up later as a "VAT adjustment."

Quick check. Take the quote and the latest pedimento from a similar shipment. The DTA line on the quote should match the paragraph of Article 49 that corresponds to the regime and origin of the goods: 8 per thousand, 1.76 per thousand, 462 pesos, or zero. The pre-validation line should read 350 pesos plus VAT. If either one does not match, there is a question pending before you sign.

Cargo handling, storage and examination: the bonded facility items

The third column is the one that varies most between quotes and depends most on the port. It is best read with the bonded facility's governing law alongside.

Cargo handling is the physical movement of the goods inside the bonded facility: unloading from the means of transport, positioning, loading onto the outbound transport. It is charged by the facility, a private operator holding a concession or authorization under Articles 14 and 14-A of the Ley Aduanera, with its own tariffs that vary by port, cargo type and unit. A serious quote states whether handling is included, estimated, or re-invoiced according to the facility's tariff, and what that tariff is.

Storage has a golden rule that almost no quote mentions. Article 15, section V, of the Ley Aduanera requires the bonded facility to provide storage free of charge for two days on import goods, seven days when the facility sits at a maritime port of entry, fifteen days on exports and thirty on minerals. The periods run in calendar days from the day after the warehouse receives the goods. From there the facility's daily rate starts. That is why an ocean shipment cleared in six days pays no storage and one cleared in nine pays two full days: the documentary calendar decides the difference.

Examination costs are the most awkward item to explain, because they depend on an event nobody controls. When the automated selection system under Article 43 of the Ley Aduanera orders a customs examination, the goods are positioned, opened, inspected and reloaded. Each of those movements is an additional handling charge at the facility, and the carrier waiting outside charges as well. The government charges no fee for the examination itself; what gets paid are the private services the examination forces you to contract. Our piece on the difference between a customs examination and a pre-clearance inspection explains when it pays to order a voluntary pre-clearance inspection to reduce the risk of the mandatory examination; here it is enough to know that the quote should state explicitly what is charged if an examination is ordered, at what rate, and to whose account.

The line items that show up later, and why

There is a pattern in the items that arrive on the expense statement and not on the quote. Almost all of them share one trait: their occurrence or their amount depends on an event that happens after the quote, and the broker left them out because quoting an uncertain event feels like over-quoting.

In our experience on both sides of the border, the seven that repeat most are these. Driver detention when clearance takes longer than planned, at an hourly rate the carrier sets and that rarely appears on the broker's quote. Container demurrage and detention charged by the ocean carrier from the day free time expires, with tiered rates that double by bracket. The bill of lading release fee and the container deposit, both from the ocean carrier, which the broker pays and re-invoices. Extraordinary handling for an examination or an X-ray inspection. Additional tariff lines on a pedimento the quote assumed would carry one. The DTA on an amended entry, 444 pesos each, when the pedimento has to be corrected after payment. And fees for services not included: classification of new merchandise, processing of a prior import permit, handling of a non-tariff regulation that surfaced during classification.

An industrial machinery distributor in the Bajío region, our client since its first import, came to us with a quote from a previous provider that showed five line items and a total it had approved without questions. The expense statement for that first shipment, which it brought to our table, showed eleven. The machinery arrived through Manzanillo, was classified under two tariff lines, and required a Mexican Official Standard (NOM) that nobody had identified at quoting time; obtaining the compliance certificate took eight days, and the container accumulated demurrage and storage through all of them. The six additional items were foreseeable from the machine's technical data sheet, and the quote had never asked for the data sheet. The operational lesson the client took away was simple: a quote is worth the information it was built with, and the next shipment was quoted with the data sheet, the confirmed tariff classification and the regulation identified before the container left origin.

The pattern repeats on expense statements of every size. The quote is built with the information available the day it is requested, and that day almost never includes the confirmed tariff classification, the documented origin, the actual arrival date, or the outcome of the automated selection system. Each of those gaps gets filled later with a new line item.

How to request the quote in writing from the start

The quote that produces no surprises was requested with the right information and separates, in writing, what is fixed from what is contingent. Five steps produce it.

1. Provide the information that determines the amounts before requesting the quote: invoice or pro forma with value and currency, technical data sheet of the goods, country of origin and the available proof of origin, intended customs regime, port and mode of transport, and estimated arrival date. With that, the broker can confirm the tariff classification, identify the non-tariff regulations, and quote the contributions at the exact rate under Article 49 and rule 1.8.3.
2. Request the quote in three columns: broker services with VAT, payments on the client's behalf with the legal basis next to each item, and third-party services with the reference tariff of the bonded facility, the ocean carrier or the carrier. An item without a column is an item that still has no owner.
3. Request a fourth section of contingencies with rates, even if the event never occurs: what is charged if an examination is ordered, what is charged per additional tariff line, what is charged for an amended entry, what the carrier charges per hour of detention and from what hour, and when storage starts to run under Article 15. The goal is that no item on the final expense statement is the first time the company sees its name.
4. Define in writing the payment mechanism for the contributions. The company can fund the broker in advance or pay the pedimento directly from its own bank account through centralized electronic payment. The second option keeps the contributions out of the broker's account, separates the columns cleanly in the books, and eliminates any advance-financing charge. This point belongs in the service agreement with the customs broker, because that is the document that survives staff changes on both sides.
5. Request that the supporting documents on the expense statement be issued in the company's name. Payments the broker makes to third parties on the client's behalf must be backed by tax invoices issued to the importing company, under the Resolución Miscelánea Fiscal rules for expenses made through third parties, and the paid pedimento is the receipt for the contributions. An expense statement with items lacking a receipt in the company's name is a cost the tax department will be unable to deduct or credit.

What this reading buys

Separating a quote into three columns and a contingency section turns a sheet with a total into an import cost model per shipment. Broker fees are negotiated once and fixed in the agreement. Contributions are verified against Article 49, rule 1.8.3 and Article 27 of the VAT law in ten minutes. Third-party services are compared against the published tariffs of the bonded facility and the ocean carrier. Contingencies are budgeted as a reserve, with a probability the company's own examination history allows it to estimate.

The CFO who works this way stops approving quotes and starts approving import costs, which is what the company actually wants to know the day the expense statement arrives. The landed-cost version of this exercise, focused on the total cost of goods delivered to the plant, is in our piece on the nine landed cost line items CFOs tend to miss, and the cost of each day lost at the port of entry is measured in what a customs delay actually costs.

How many line items did your company's last expense statement carry that were absent from the quote that originated it? That number is the starting point.

This is how we build quotes at Joffroy: three columns, the legal basis next to each contribution, and contingencies with rates. If you want to review the cost structure of your next shipment under that standard, talk to a Joffroy expert.
