Mexico Steel and Aluminum Import Notifications
Guidance to reduce rejections in Avisos Automáticos for U.S. exporters
On June 11, 2025, the Mexican government, via the Secretariat of Economy (SE), issued an orientation guide to help Mexican importers and U.S. exporters understand requirements and avoid rejections when submitting Automatic Import Notifications (AAIPS) for steel and aluminum products.
Below are the key points U.S. steel and aluminum exporters should prioritize:
* Accurate Product Description: Align with mill/quality certificates, including technical and chemical specs per SNICE guidelines.
* Mandatory Characteristics: Specify finish, coating, steel type, accessories, properties, shape, dimensions, and composition by heat.
* Transformed Goods: Document raw material mill data and final product certificates, ensuring traceability via heat numbers.
* Certificate Compliance: Include kilogram-based volumes, producer details, and handwritten signatures; digital signatures require a notarized letter.
The Secretariat of Economy’s guide and dedicated website recommend avoiding errors such as inconsistent quantities in submissions, incorrect unit conversions (e.g., meters to kilograms), or missing translations. Avoid submitting just one “Aviso” per tariff code, country of origin, unit price, and certificate. Frequent exporters should enroll in Mexico’s Annual Steel Importers Registry (RGCE/Rule 2.2.26, Fraction B) to simplify processes.
While the Mexican importer is typically responsible for meeting all import requirements, it is beneficial for U.S. exporters to have proactive coordination with Mexican importers to verify certificate compliance before submission.
This guidance and the website provide resources to assist U.S. exporters and Mexican importers in managing Mexico’s AAIPS challenges efficiently.
