Shifting Tariffs, Tightened Rules: How Mexico’s New Customs Changes Impact U.S. Imports — and How Brokers Like All Borders Inc. Can Help

The fast-changing global trade landscape just got more complex. In mid-August, Mexico raised its tariffs on Chinese imports to 33.5%, up from 19%, and added new data-reporting requirements that now require both the U.S. seller’s tax ID (EIN) and the Mexican consignee’s tax ID to be declared on customs documentation.

These changes—part of Mexico’s Plan Nacional de Desarrollo under President Claudia Sheinbaum—signal the country’s effort to strengthen trade oversight, support domestic manufacturing, and capture more revenue from cross-border e-commerce.

What This Means for U.S. Sellers

For U.S. companies that have relied on Mexico as a nearshoring and fulfillment hub, the new rules introduce added complexity and compliance risk:

• Goods of Chinese origin now face steep duties, even if they’re fulfilled from U.S. warehouses.

• Enforcement varies by port and shipping channel, with some couriers applying full tariffs and others recognizing USMCA exemptions under $50.

• Footwear and textile sectors are especially affected, as changes to Mexico’s IMMEX program limit temporary imports and impose duties of 25% or more.

As a result, many businesses are rethinking their logistics strategies, moving fulfillment back to the U.S. to ensure smoother customs clearance and avoid potential fines.

How This Affects Imports Into the U.S.

While these new Mexican policies target inbound shipments, their ripple effects reach northward:

• Reduced use of Mexico as a re-export base means more goods will be imported directly into the U.S. for storage and fulfillment.

• U.S. importers may see higher demand for customs services to manage increased inbound flows and complex origin declarations.

• Businesses will need to reassess their supply chains to stay compliant with both U.S. and Mexican trade regulations.
