Paying the duties doesn’t give you the right to import. Plenty of goods also need an authorization from the agency that regulates them — what the trade calls non-tariff regulations (RRNA). Without that permit, the operation doesn’t move even with the customs entry (pedimento) paid.
Who regulates what
| Agency | Typical goods |
|---|---|
| COFEPRIS (health authority) | Pharmaceuticals, medical devices, food, supplements, cosmetics, hygiene products, pesticides |
| SEMARNAT (environmental authority) | Protected species (CITES), hazardous waste, timber, forest products, ozone-depleting substances |
| SEDENA (defense ministry) | Weapons, ammunition, explosives, fireworks and controlled chemicals |
| SADER / SENASICA (agriculture) | Live animals, products of animal or plant origin, seeds, pet food |
| Ministry of Economy | Quotas, prior permits, automatic notices (steel, textiles, footwear, used vehicles) |
| Health Ministry / CENAPRECE | Certain products with specific health implications |
How to find out if your product needs a permit
Same as everything in Mexican customs: by tariff code. Every code in the tariff schedule (TIGIE) has its regulations attached. Look yours up in the calculator and check the regulatory file, or ask your customs broker for the regulatory analysis before you buy.
The authorization types you’ll see most
- Prior permit — express authorization from the Ministry of Economy to import certain goods. You apply, they resolve; it can be denied.
- Automatic notice — not discretionary, but without it you don’t clear. Common in steel and textiles.
- Quota — a limited quantity at a preferential duty rate; allocated by auction or direct assignment.
- Sanitary registration or notice — COFEPRIS, depending on the product’s risk level. A drug needs a registration; a cosmetic, a notice.
- Animal- or plant-health certificate — SENASICA, for agricultural product.
Everything runs through the single window
Mexico’s trade single window (ventanillaunica.gob.mx) is the one place these permits are requested and tracked. You need a valid e.firma (the government e-signature). Each permit generates a folio number your customs broker declares on the customs entry under the corresponding identifier code.
One change worth keeping in mind: by decree of May 4, 2026, the platform operates as VUTCE (the foreign-trade single window) and moved from the tax authority (SAT) to the ATDT digital agency, along with creating the Single Foreign-Trade File. Plenty of people still call it VUCEM — but if your team hasn’t reviewed access credentials and internal procedures since May, it’s worth doing.
Having the permit isn’t enough — it has to be declared. We’ve seen operations stopped with a valid permit in hand, simply because the identifier never got captured on the customs entry. Confirm with your broker that it was declared.
Lead times: the most underestimated factor
An automatic notice can come through in days. A COFEPRIS sanitary registration can take months. If your product needs one and you find out while the container is already on the water, no forwarder or broker can save you: the goods go to a bonded facility racking up storage while you work through the paperwork.
The right sequence
- Pin down your product’s tariff code.
- Identify all of its non-tariff regulations (there can be several at once).
- Work out how long each permit takes and start the slowest one first.
- Place the purchase order once the regulatory path is clear.
- Hand the folios and permits to your broker before the cargo arrives.
