US Compliance & Audit Note (Appendix 7)
Over 80% of Anexo 24 and SCCCyG (Anexo 30/31) discrepancies come from conversion drift between your ERP unit (e.g., Code 06 Pieza) and the mandatory TIGIE Tariff Unit (e.g., Code 01 Kilo or Code 04 Metro Cuadrado). Always maintain 6-decimal conversion factors per lot.
Note: The official descriptions and application rules in the searchable table below preserve the exact statutory Spanish text published by SAT in the DOF, as Mexican customs validators (SAAI) and audit notices reference the Spanish statutory text verbatim.
