Anexo 22 Appendices: Searchable SAT Pedimento Catalogs

In Mexican customs law, Anexo 22 of the General Foreign Trade Rules (RGCE) is the statutory instruction manual that governs every field on a Mexican pedimento. Whenever a US controller, ERP systems architect, or trade compliance manager reviews a Mexican customs entry or audits SAT's monthly Data Stage (501/551/554) files, every 2-character code on that document comes from one of the Appendices of Anexo 22.

Because SAT publishes Anexo 22 as a dense, multi-hundred-page Spanish PDF in the Official Gazette (DOF), looking up a single identifier or unit code is slow and error-prone. Below are all 1,157 official records across 19 searchable appendices, verified one-by-one against the official SAT publication.
