For Chinese companies planning to export products to Mexico, understanding the local compliance certification system is the first critical step to successfully entering the market. Among the various certifications in Mexico, NOM and FIDE are the two most relevant for electronic and electrical products. The former is a mandatory market access standard, while the latter is a voluntary energy efficiency label. This article provides a systematic overview of the key aspects of both certifications, offering practical compliance guidance for exporters.

The core difference between the routine test (factory test) and the type test for high-voltage three-phase asynchronous motors is:
The routine test is a "factory pass certificate" performed on every motor to verify the manufacturing quality of each unit. The type test is a "design validation report" performed on a sample from the same specification to verify the design and performance compliance of the entire series.

The insulation class of high-voltage three-phase asynchronous motors is a core technical indicator defined based on the maximum allowable operating temperature of the insulation materials.

There are many factors that affect the efficiency of high-voltage motors, including motor body losses, operating conditions, design and structural factors, as well as installation, maintenance, and environment. A detailed analysis is provided below.

The five core performance parameters of a motor are key indicators for evaluating its performance, suitability for application scenarios, and selection criteria. They directly determine the operating state and effectiveness of the motor, including rated power, rated voltage, rated current, rated speed, and rated frequency.

The current mandatory Energy Efficiency Label catalog in China covers 38 product categories. Key motor-related products included are:
• Permanent Magnet Synchronous Motors
• High-Voltage Three-Phase Squirrel-Cage Induction Motors
The implementation rules for these products are specified in the 2025 catalog. For Permanent Magnet Synchronous Motors, the new rules took effect on January 1, 2026. For High-Voltage Three-Phase Induction Motors, the rules will take effect on April 1, 2026.
