The short answer
IMMEX is a program authorized by Mexico's Ministry of Economy that lets you import goods temporarily without paying import taxes, on one condition: those goods are transformed, repaired or serviced, and then leave the country.
The acronym comes from the decree that created it — Manufacturing, Maquiladora and Export Services Industry — published in Mexico's Official Gazette on November 1, 2006. It merged the older maquila and PITEX programs into one.
The operative word is temporarily. This isn't an exemption: it's a deferral conditioned on the goods leaving. If they stay in Mexico, someone pays.
The five modalities (article 3 of the decree)
A single program can include these modalities:
| Modality | When it applies |
|---|---|
| Holding company | One program covers the operations of a certified "holding" company and one or more subsidiaries |
| Industrial | There's an industrial process of manufacturing or transformation of goods destined for export |
| Services | Services are performed on export goods, only for activities the Ministry determines |
| Shelter | One or more foreign companies supply the technology and productive material without operating the program directly |
| Outsourcing | A certified company without its own facilities manufactures through third parties registered in its program |
Shelter is the one foreign brands typically use to produce in Mexico without setting up their own entity. Outsourcing is the one people confuse with "outsourcing logistics," which is an entirely different thing.
The time limits: how long goods can stay
Article 4 sets them by type of goods, and they are not extendable:
- Up to 18 months: fuels, lubricants and materials consumed in the production process; raw materials, parts and components integrated into the exported goods; containers and packaging; labels and brochures.
- Up to 2 years: shipping containers and trailer boxes.
- For the life of the program: machinery, equipment, tools, molds and spare parts for production; lab, measurement, quality-control and computing equipment; administrative equipment.
There's a fourth limit almost nobody mentions: goods transferred through virtual operations get 6 months, except when transferred by a domestic supplier without a program, in which case it's 18.
And there's a list — Annex I of the decree — of goods that simply cannot be imported under the program.
The obligations nobody mentions in the sales meeting
Having IMMEX isn't holding a benefit: it's accepting a control regime. Among the decree's obligations:
- Keep automated inventory control per the tax authority's rules (article 24, fraction IX). Not a spreadsheet: a system that traces every temporary entry through to its return.
- Keep the goods at the addresses registered in the program. Moving product to an unregistered warehouse is non-compliance, not a logistics detail.
- Report changes in corporate name, address, shareholders or legal representative.
- File an annual electronic report of total sales and exports for the prior fiscal year, no later than the last business day of May (article 25).
The date worth putting on the calendar
That last obligation has teeth. If the annual report isn't filed in May, the temporary-import benefit is suspended. And if it still hasn't been filed by the last business day of August, the decree is blunt: the program is definitively cancelled as of September 1 of that year.
In 2026 that last business day of August falls on Monday the 31st. If your company — or your supplier, or your contract manufacturer — has been suspended since May, this week is literally the last window before cancellation becomes final.
Why most e-commerce brands don't need IMMEX
Here's the uncomfortable part, and the reason for this post.
IMMEX is designed for exporting. Its entire scaffolding — the deferral, the deadlines, the inventory control, the return obligation — exists because the goods are assumed to leave the country.
If your brand imports to sell in Mexico, IMMEX doesn't apply: your goods stay, clear customs definitively and pay their taxes on entry. Chasing an IMMEX for that is forcing a domestic-sales operation into a suit tailored for something else, and it usually ends in non-compliance.
The confusion comes from both routes starting identically — a container at a port — and separating on a single question: is this product leaving Mexico, or being sold here?
| If your product… | The route is… |
|---|---|
| Is transformed and exported | Temporary import (IMMEX or another incentive regime) |
| Is sold in Mexico | Definitive import and normal customs clearance |
| Is stored before you decide | A deposit regime, not IMMEX — see bonded warehouse vs. 3PL |
Worth saying plainly: Ecommex does not operate under an IMMEX program and does not import temporarily on behalf of third parties. We work with goods that have already cleared customs. If you need an IMMEX structure, the person to build it is a foreign-trade specialist, not your logistics provider.
What we do handle on that inventory — once it's yours and has paid what it owed — is the manual work it still needs before it can sell: labeling, relabeling for Mexican standards, kitting, repacking.
FAQ
Are IMMEX and maquiladora the same thing? Nearly. "Maquiladora" is the historical name; since 2006 the operative figure is the IMMEX program, which absorbed the old maquila and PITEX programs.
Does IMMEX exempt you from VAT? It defers payment while the goods sit under the temporary regime and the return obligation is met. To avoid paying it on import you also need the VAT and excise-tax certification from the tax authority, which is a separate process from the program itself.
Can I sell in Mexico what I imported under IMMEX? Not as-is. To stay in the country, the goods must change regime and pay the corresponding taxes. Doing it late, or not at all, produces some of the most expensive tax assessments in Mexican foreign trade.
Do I need IMMEX to label imported product? No, if the product has already cleared customs. Labeling to comply with NOM-051 and other standards can be done on definitively imported goods, in an ordinary warehouse.
Who authorizes the program? The Ministry of Economy, after a filing with the tax authority. The decree also requires publishing information about the authorizations granted.
If your goods are already in Mexico and what you need is someone to label, assemble and make them shelf-ready, here's how our labeling and light assembly works.
