Definition
A free trade zone (or analogous promotion regime) lets you store, handle, or transform goods with tax or customs benefits under country-specific rules. In Mexico, freight buyers must translate the term to IMMEX, bonded facility, or the applicable live regime — not a generic model from another continent.
If you mix “nationalized” and temporary inventory in the same aisle without tags, the problem is not freight — it is the regime.

What it means in practice (Mexico)
The benefit always comes with obligations: deadlines, inventories, pedimentos, and traceability. Warehouse and transport are links in the same file.
Do not confuse real-estate “FTZ” marketing with the regime your customs broker files with SAT.
Why it matters by role
| Role | What they need | If it fails |
|---|---|---|
| Trade compliance | Clear pedimento and regime | Fine / program loss |
| Warehouse / WMS | Segregated inventory | Mixed customs status |
| Traffic | Docs aligned to the move | Carta Porte vs reality |
| Accounts payable | Trip + fiscal file | Pays freight without support |
What not to confuse it with
Promotion / bonded regime
- Conditional benefit
- Inventory and deadlines
- Pedimento / customs control
Ordinary national DC
- Already nationalized goods
- No IMMEX clock
- Different risk set
1.Bonded vs industrial park
A park can host IMMEX without being the “FTZ” you imagine legally.
2.Nearshoring ≠ regime
Nearshoring is location strategy; IMMEX is a program. See nearshoring.
Mexico 2024–2026: IMMEX and volume
INEGI’s IMMEX bulletin reports on the order of 6,520 establishments in the program and millions employed — the volume pushing Norte/Bajío freight and crossings.
Every trip to/from a bonded facility needs coherence among pedimento, shipment, and Carta Porte. The typical failure is treating the trailer as “generic” while the SKU is still temporary.

Expensive mistakes
1.Copying another country’s definition
Mexico has its own programs; verify the live one.
2.Mixing inventories
Temporary and nationalized in the same bin without control.
3.Freight without a visible pedimento
Traffic moves boxes; trade cannot explain them.
4.Carta Porte PDF without XML
AP cannot audit nodes.
OCL and the trip file
OCL joins trip milestones, CFDI/Carta Porte, and evidence in one file. It can stamp invoices and Carta Porte. It does not prepare pedimentos or replace the customs broker.

Key takeaways5 points
- In logistics speech, “free trade zone” usually means a promotion regime or bonded facility where goods are stored/transformed under tax/customs benefits with strict rules.
- In Mexico, the operational analogues are IMMEX and bonded / strategic bonded facilities — do not copy another country’s regime.
- Without customs clearance and pedimento discipline, the tax benefit becomes SAT risk.
- TMS/WMS must tag regime and segregated inventory; freight needs Carta Porte / CFDI aligned to the real move.
- OCL binds the trip to the document file; it can stamp invoices and Carta Porte. It does not replace the customs broker.
Is your regime in the pedimento… and on the trip?
