What the rules cover

What the rules ask for

Where it goes wrong

Approved once. Then it drifts.

One approved set of product information ends up in many channels, markets and languages. Along the way it gets shortened, translated and reworded, and some versions end up without the warnings or details these rules require.

How Arbitr helps

So how do you keep front-of-pack warnings under control across every market and channel?

Read every version by hand? Or use AI to check what you publish against what you've already approved.

Check everything manually?

  • Too much to check. Too many channels, versions and translations to cover every market.
  • Drift goes unseen. Nothing tells you when a version moves away from the approved product information.
  • Changes mean starting over. No easy way to re-check what's live when your approved rules, claims or terms change.

Let Arbitr do it for you

  • Scan what's live. Go through every live version, in every language, against your approved rules, and find every pack shot and listing where a warning seal or legend has gone missing.
  • See what needs attention. Get a clear report of anything that might have moved away from what was approved.
  • Check what comes next. Check everything new against what you approved, across every channel, market and language, before it goes live.

Approve once. Apply everywhere.

FAQ

Questions about Mexico's front-of-pack warning labels

For your teams
Where do NOM-051 warning seals go missing across our channels?

Mostly away from the shelf. The 2020 modification puts the seals and legends on the label itself,1 and we usually find older or cropped versions of the pack in:

  • marketplace and delivery-app listings
  • retailer feeds and planograms
  • promotional sleeves and multipacks
  • ads and social posts showing the pack
  • imported stock relabeled for Mexico
When a recipe or nutrient limit changes, how do the seals stay in step?

Treat the seal set as approved content tied to the recipe and the phase it was calculated under. When the formula changes, or a new phase applies, recalculate, update the label, then replace every pack shot and listing image that shows the old one. Our packaging and labels page shows how teams track this.

What should we record for each product's front-of-pack label?

Keep one record per product: the nutrient profile, the seals and legends it carries, the phase it was calculated under, the label artwork version, who approved it, and every channel where the pack image appears. When a question comes in, you can show the calculation and the label together.

How it applies to a specific label is a question for your legal adviser. Where that label appears across your markets and languages is a question Arbitr answers.

Who needs to know about Mexico's front-of-pack warning labels?

Regulatory and R&D teams usually own the calculation, but packaging, brand, e-commerce and trade marketing all publish the pack, and so do retailers and delivery apps. A short briefing for each, with your own packs, helps. Other labeling rules are on our product labeling hub, including UKCA marking for Great Britain.

About the rules
When did Mexico's front-of-pack warning labels start to apply?

On October 1, 2020, according to the modification published in the Diario Oficial de la Federación on March 27, 2020. Its nutrient limits then tightened in phases from October 1, 2023 and October 1, 2025.1

Did Mexico change its front-of-pack warning labels in 2025?

A draft change was published. The Secretaría de Economía put PROY-NOM-051-SE/SSA1-2025, a draft modification of numeral 4.5.3 on legends, out for public consultation in a document dated October 27, 2025.3

Is NOM-051 the same as NOM-050?

They're separate standards. NOM-051 covers the labeling of prepackaged food and non-alcoholic beverages, according to its text,1 while NOM-050-SCFI-2004 covers commercial information for other consumer products sold in Mexico.
