IMMEX warehouse for US shippers
IMMEX warehouse for US shippers: what to ask before you commit
What makes a warehouse handling temporarily imported goods different, and the questions that separate real control from empty floor space.
Independent editorial resource
Mexico cross-border logistics for US shippers
An independent resource on Mexico–US logistics: Laredo cross-docking, drayage, and IMMEX warehousing, and how to evaluate a provider.
Mexico–US cross-border logistics is where a manufacturing operation becomes physical: warehouses, crossings, carriers, customs brokers and cross-docking. It is also where an operation that looks clean on paper can break if coordination fails.
This section is a set of editorial guides to evaluate providers and understand the process: what to ask an IMMEX warehouse, how Laredo cross-docking works, and which controls you keep even when you outsource the work. It is not a directory or a service offering.
Editorial note: ammex.org.mx is an independent resource operated by Heberey LLC. It does not represent or affiliate with AMMEX, Index Metropolitana, INDEX Nacional, any authority, or prior operators of the domain.

Frequently asked questions
Is cross-border logistics the provider’s responsibility or mine?
Both are involved, but document and compliance responsibility stays with the company that owns the goods and the IMMEX program. A 3PL, carrier or customs broker executes parts of the process; traceability and consistency with the customs declarations remain yours.
What is border cross-docking?
It is transferring freight from one truck to another with little or no storage, usually when switching between US and Mexican carriers at a crossing like Laredo. Done well, it cuts time and inventory; coordinated poorly, it creates delays and document discrepancies.
Do I need an IMMEX warehouse to operate?
It depends on the model. What matters is not just that a warehouse exists, but that temporarily imported goods are controlled under the regime and reconciled with inventory and pedimentos. This section helps you frame those questions; it is not advice.
Where do I verify the applicable rules?
In official sources such as the SAT, SNICE, VUCEM and the Diario Oficial de la Federación, plus customs brokers and qualified advisors familiar with the specific operation.
