Background and Relevance of the Industry

The Mexican auto parts industry, represented by the Industrial National Association (INA), has proposed differentiated tariffs for components sourced from Asian countries, particularly China. This move aims to maintain the competitiveness and fluidity of the domestic manufacturing sector while ensuring a considerable tariff for aftermarket parts.

INA’s Proposal

Francisco González, the president of INA, advocates for a tariff-free environment for manufacturing parts imported from China. He emphasizes that this approach will prevent the loss of competitiveness and ease of access for domestic manufacturers. Simultaneously, González requests that aftermarket parts be designated as “aftermarket” to facilitate smoother imports and tariff application based on market impact.

Import Data

Mexico imported $7.249 billion worth of automotive parts and components from China, accounting for 18.5% of total foreign purchases, along with $2.076 billion from South Korea (5.3%), according to INA data from S&P Global.

Current Tariff Review

The INA is currently reviewing around 200 out of 447 tariff fractions in the trade balance, focusing on components used for manufacturing and aftermarket parts. The association seeks clearer definitions to distinguish between production and aftermarket components, ensuring that production remains fluid and accessible.

Supporting Statements

Gabriel Padilla, the INA director, highlights that Asian-sourced auto parts, especially electronic components and plastic injection moldings, strengthen shared manufacturing schemes with the United States while adhering to origin rules.

Padilla also notes that Chinese investments in Mexico’s auto parts sector remain at 3%, with no recent increase in Chinese investor presence.

Tariff Impact on Market Segments

Padilla explains that the proposed tariffs target imports affecting the aftermarket and replacement parts market. This sector has experienced significant pressure in provisioning components and parts in Mexico, potentially facing the most substantial impact.

As the T-MEC (Mexico, United States, Canada) treaty undergoes review, efforts focus on developing domestic supply chain capabilities.
