Export Packaging for Mexico: 3 Real Compliance Requirements — NOM Official Standards / Spanish-Language Labels / TEF Measurement Verification: When a Printer Takes a Mexican Order, Which Three Tables Should It Split the Spanish Copy Into First?

In March 2026, a customer selling chili powder approached us with an order for 20000 paper boxes of 250g each for export to Mexico.

The customer had already prepared the Spanish label copy through a translation company in an Excel spreadsheet, with one field per row. He sent us the file and asked: “Can we just print it as it is?”

We did not immediately reply to say whether we could print it. We responded first: “Hold on. Let us first work through this spreadsheet field by field.”

The next day, we sent back a three-page field checklist. After reviewing it, the customer said: “I thought we were done once the translation was finished.”

This was not a sign that the customer was unprofessional. The compliance structure of the Mexican market is inherently different from that of most export destinations. It is not “one set of regulations governing everything”; rather, each track governs a different segment. Translation only addresses how the wording is expressed within one of those tracks. A translation company will not address many issues on the other two tracks, and neither will a freight forwarder; often, the customer will not think of them either.

This article explains what each of the three tracks governs, the three tables into which we divide the Spanish copy, and what a printer can and cannot promise for orders for Mexico.

Track 1: NOM-051 — Governs What Is Stated on the Label

The first track customers encounter—and usually the only one they have heard of—is the NOM-051 series for prepackaged food labels. It governs the wording printed on labels and packaging: the product name, how it must be written, how the ingredient list should be arranged, the format of the Nutrition Facts table, the font size used for net content, and how dates should be printed.

The item most likely to cause problems on this track is not whether the Spanish translation is accurate, but the dates.

Mexico uses two types of dates for prepackaged foods. They have different meanings and are generally printed separately:

• Best-Before Date (FAB / Best-Before End Date)—the date before which the product is at its best quality and the relevant safety-related expiry point.
• Commercial Shelf-Life End Date (CAD)—the date before which the product may legally be sold.

A common practice on export orders is to translate the “12-month shelf life” stated on the customer’s domestic packaging directly into a single line of Spanish text. In Mexico, this will almost certainly result in a rejection. Domestic packaging generally states a generalized number of months, whereas Mexico requires a specific date and often requires two dates.

For the printer’s work, the date format, position, font size, and relative position of the two dates on the layout must all be settled in advance. Dates are generally printed near the bottom, with enough optically readable space around them. This is not a regulatory requirement; it is a practical requirement of shelf display. The bottom of a package sits directly against the shelf beam, so a date that is obscured by the beam or folded into the bottom of the box may be invisible to consumers.

The second frequent issue on this track is the Nutrition Facts table. Mexico has its own format requirements, including per serving / per 100g, energy expressed in both kilocalories and kilojoules, and separate presentation of sodium content. These differ from the presentation used under China’s GB 28050. Translation companies generally translate only the wording and do not restructure the table. As a result, the Spanish copy sent by the customer often includes a Chinese-language table as a separate attachment. The printer cannot typeset this portion; the customer must return a restructured Spanish version.

Track 2: NOM-008 — Governs the Information the Packaging Itself Must Carry

Customers are usually almost completely unaware of this track, yet it is precisely the one the printer should raise proactively because it concerns information printed directly on the packaging.

The information covered by this track generally falls into the following categories:

One particularly practical issue on this track is whether the “packaging manufacturer name and address” should identify the printer or the customer’s brand owner. Many brand owners assume that listing their own name is sufficient, but this depends on Mexico’s definition of “packaging manufacturer” and on the customer’s own distribution structure. The printer cannot make this determination for the customer; it must be confirmed by the customer in writing. The printer should incorporate this confirmation step into the artwork approval sheet, because changing packaging after the steel-seal production has been completed means reworking the entire batch.

Another issue is often overlooked: the packaging material marking and the recycling marking from the third track must be kept separate. If the two markings are crowded together, or if a sticker covers the triangular recycling-arrow symbol, the issue will be identified during retail inspection at Mexican supermarkets.

Track 3: NOM-010 — Governs Whether the Quantity Is Correct, Also Known as the Customer’s TEF Measurement Verification

In the customer’s own terminology, “TEF measurement verification” refers to this track. It governs the permissible deviation between the declared net content and the actual fill quantity, as well as the measurement verification that must be performed by a qualified verification body (verificador) before the product is sold in Mexico, with a verification number obtained. For many product categories, this number must be shown on the packaging.

First, the printer’s boundary must be clear: measurement verification is the customer’s obligation, not a printer’s process. The printer cannot perform the verification itself and should not promise to do so. There are three specific things the printer must do on this track:

• Lock the declared value into the layout as a hard parameter. The declared net content, unit of measurement, font height, and position below the main display panel of the package cannot be changed once finalized, because changing the declared value means changing the compliance documentation.
• Reserve space for the verification number. If the customer intends to print the number issued by the verification body on the package, the printer must know the length of the number in advance, including the prefix letters and number of digits, as well as the customer’s intended printing position. If no space has been reserved and a label is applied after printing, the applied label will cover the primary information.
• Confirm that no unsupported promises are made regarding structures that affect fill quantity. If the internal dimensions or containment structure of the box, such as pockets, compartments, or leveling mechanisms, could affect the actual fill quantity, the customer must have the verification body assess the final package rather than an early sample.

The most common misconception on this track is that the verification number is part of the product model number, or that printing it on the label is sufficient. The number is part of the verification documentation. Its position is determined jointly by the verification requirements and the packaging layout and cannot be arranged independently by the printer.

How We Divided the Spanish Copy Into Three Tables

Returning to the chili powder customer, what we sent him was not a set of “translation recommendations.” It was three tables. These tables later became our standard procedure for handling orders for Mexico.

First table: field checklist. One field per row, with six columns:

The purpose of this table is to turn typesetting from guesswork into calculation. Spanish is generally 30% to 60% longer than Chinese, and the packaging manufacturer’s name and address and the Spanish ingredient list are the two items most likely to reveal that the copy will not fit before printing begins. Once the field checklist is available, the layout can be changed on the spot if something does not fit.

Second table: track assignment table. Each field is assigned to one of the three tracks: a NOM-051 field, a NOM-008 field, a NOM-010 field, or “Customer Optional (Not Mandatory).” Once the assignments are clear, we can answer immediately when the customer asks whether a particular item can be omitted. Mandatory and non-mandatory items are treated separately under the regulations. Treating a mandatory item as optional to save space simply shifts the risk to the production stage.

Third table: list awaiting the customer’s written confirmation. It includes only matters that the printer cannot decide for the customer and that cannot be changed after a decision is made. Our list contained five items at the time:

• Whether the packaging manufacturer’s name and address should identify the printer or the brand owner
• What the two dates are (FAB and CAD, rather than a generalized number of months)
• Who will restructure the Nutrition Facts table in Spanish and return the completed version
• Whether the verification number will be printed on the package, who will provide it, and on which panel it will appear
• The relative positions of the material marking and the recycling marking

Only after the customer confirmed these five items did we approve the steel-seal production. On the same day that we sent the three tables, the customer discovered internally that the original translation had omitted one item: the CAD date. If the boxes had been printed directly from the translation, all 20000 would have been held in a warehouse in Mexico because the date field was noncompliant.

What a Printer Can and Cannot Promise for Orders for Mexico

This must be made clear, or it will often be discussed only after a problem occurs.

What can be promised: faithful layout reproduction (the Spanish wording on the customer-approved artwork reproduced word for word and the field positions matching the approved artwork), prepress file compliance (fonts converted to outlines, bleed and resolution, and bleed and trim marks), no conflicts between fields (the placeholders have been calculated using the field checklist), and support in providing a code or label position for the customer’s verification number. Translation accuracy and the applicability of regulations are outside the scope of what we can promise.

What cannot be promised: “This package is guaranteed to be listed on shelves in Mexico” or “This label complies with Mexican requirements.” The reason is simple: the conditions applicable to the same package design differ depending on whether it is used for food or industrial goods sold in Mexico, and whether it enters the market through a channel with a local Mexican distributor or is sold directly through a cross-border platform.

Our formal response template therefore has four parts: the first part clearly separates the three tracks (the second track is the one customers most often overlook); the second part provides the three tables; the third part lists the five matters requiring the customer’s written confirmation; and the fourth part defines the printer’s commitment boundaries.

After reading it, the customer does not feel that responsibility has been shifted elsewhere, because every concern has been answered directly. At the same time, we maintain our own responsibility boundaries: we execute cleanly the parts that are our responsibility and remain unequivocal about the parts that are not ours to assume.
