Within Mexico’s General Foreign Trade Rules, the updated Annex 24 now has stricter requirements for inventory control systems of certified companies.
On November 15, 2024, Mexican customs authorities will require online access to the inventory control systems of certified companies. This access will allow Mexican customs authorities to verify that inventory records comply with current regulations and that temporarily imported goods are properly re-exported.
This change brings stricter oversight to U.S. exporters and U.S. companies with branches in Mexico under Mexico’s certified companies scheme.

Mexican companies must now submit the required information within 48 hours of importing goods into Mexico. This new regulation also requires companies to provide Mexican Customs with online access, including sharing the system account and password, for inspections. This accelerated timeline means that companies need efficient, real-time processes to capture and report data immediately upon arrival of products in Mexico. This change may require system upgrades or workflow adjustments.
Failure to meet these deadlines and access requirements could result in penalties or delays, so it is essential to update inventory management procedures to remain compliant. This regulatory change will be fully effective as of November 15, 2024.
