IMMEX Program Support for Manufacturers
Updated October 2026 · By the ELTOSAI brokerage team
Manufacturing in Mexico under the IMMEX program changes how your imports clear customs: temporary-import pedimento codes, duty deferral, virtual transfers between authorized companies, and strict inventory controls. We support manufacturers through the full setup and the daily operation.
What we do for IMMEX operators
For companies that already hold IMMEX authorization, we coordinate temporary-import pedimentos with the correct declaration codes, manage the duty-deferral logic on every entry, and keep the documentation trail your Anexo 24 inventory control requires. For companies without authorization, we structure imports through shelter providers or support your own application with realistic timelines.
- Temporary-import pedimentos with correct claves for IMMEX entries
- Virtual pedimentos for transfers between IMMEX companies
- Coordination with your broker on IVA/IEPS certification implications
- Shelter-provider structures for manufacturers without their own authorization
Common IMMEX logistics pitfalls
The expensive mistakes we see: mixing definitive and temporary import codes on the same operation, missing the export deadlines that keep the deferral valid, and treating IMMEX freight like standard imports at the broker level. All three are avoidable with a forwarder that understands the regime.
Start with a compliance review
If you are setting up manufacturing in Mexico or already operate under IMMEX, talk to us before your next shipment. We review your current import flow, flag regime mismatches, and design the freight and customs structure around your program. One business day response, usually faster.
