When you file a customs entry, the first big decision isn’t how much you pay: it’s under which regime your goods enter. That choice determines whether taxes are paid or deferred, how long the goods can remain in the country and what obligations you take on. Choosing wrong — or by default — can cost you taxes you didn’t have to pay or, worse, non-compliance. Mexico’s Customs Law recognizes six regimes; here’s each one in plain language.
Why the regime defines everything
The customs regime is the “legal figure” under which goods enter or leave the country. Three things depend on it: the tax burden (whether you pay the import taxes upfront or defer them), the time the goods may remain, and what you can do with them (sell, transform, re-export). It’s not paperwork: it’s a strategic decision that starts before you buy.
1. Definitive
The most common and the simplest to understand. The goods enter (or leave) to stay: on a definitive import you pay all charges and the goods are free to be sold in Mexico, with no obligation to return them. It’s the natural regime for anyone importing finished product for sale or their own use.
2. Temporary
The goods enter for a limited time and with a specific purpose, with the obligation to return them abroad. It has two major uses:
- To return in the same condition: machinery, equipment, containers or goods that enter and leave without changes (for a trade show or a temporary project, for example).
- For elaboration, transformation or repair: the basis of IMMEX programs, which allow inputs to be imported temporarily — deferring taxes — to produce goods that are later exported. It’s the regime that sustains export manufacturing in Mexico.
3. Fiscal Deposit
The goods are stored in an authorized General Deposit Warehouse with taxes suspended. While there, you can decide their fate flexibly: withdraw them gradually for definitive import (paying as you need them), return them abroad, or even carry out certain operations. It’s useful for managing cash flow and for anyone who doesn’t want to pay the full tax at once.
4. Transit of goods
Lets you move goods from one customs office to another under customs control, without having cleared them yet at the point of entry. It can be internal (between two national customs offices) or international (when goods cross the country to or from abroad). It’s key in logistics operations where clearance is better done at an inland customs office rather than at the border.
5. Elaboration, transformation or repair in a bonded facility
The goods enter a bonded facility to undergo elaboration, transformation or repair processes, and are then returned or assigned to another regime. It combines storage under customs control with the ability to add value to the goods within the facility.
6. Strategic Bonded Facility (RFE)
The most complete regime for adding value with tax benefits. It lets you bring goods into a strategic bonded facility to store, handle, safeguard, display, sell, distribute, elaborate or transform them, with taxes suspended and generous timeframes. It’s a figure designed for logistics and manufacturing operations that want to use Mexico as a platform.
How to choose well
The question isn’t “which is the best regime?” but “which one fits what I’m going to do with the goods?” Selling them as-is? Definitive. Transforming them to export? Temporary under IMMEX. Want to defer taxes and manage cash flow? Fiscal deposit or RFE. On top of this come the incentive programs — such as PROSEC or Rule Eight — which can make the operation cheaper still depending on the regime. The most expensive mistake is going definitive “out of habit” when your operation qualified to defer taxes.
At TradeWay
Choosing a regime is a decision of fiscal and operational architecture, not just another field on the customs entry. Because we integrate consulting, clearance and logistics under a single point of contact, we see it whole:
- We diagnose which regime fits based on what you’ll do with the goods and your cash flow.
- We assess programs (IMMEX, PROSEC, RFE) that could reduce your tax burden.
- We run the clearance under the correct regime, with our bonded warehouse in San Luis Potosí as a base.
If you’re not sure which regime you should be importing under, get in touch and we’ll review it against your specific case.
