Mexico's share of US goods imports (12 months)

## What this measures

Mexico's share of US goods imports measures the proportion of all US merchandise imports that originate from Mexico over the trailing twelve months. It reflects Mexico's position in US supply chains relative to other trading partners.

## Background

Imports from Mexico as a share of all US goods imports, trailing 12 months.

Σ12 US goods imports from the partner ÷ Σ12 US goods imports from the world × 100, Census FT-900 via FRED (IMPMX, IMP0004). Read alongside China's share: China falling while Vietnam and Mexico rise is partly trade rerouted through them, not only decoupling. Computed monthly by /api/cron/fred-composites.

## Why it matters

A rising share signals that US firms are sourcing more goods from Mexico, whether through nearshoring, trade diversion, or Mexican export growth. Organizations with North American supply chains use it to gauge competitive pressure, tariff exposure, and the depth of cross-border integration. Shifts in this share can affect freight capacity, inventory lead times, and the regional balance of manufacturing and logistics investment.

## How to read it

A rising share means Mexico is growing faster than other sources of US imports or displacing them; a falling share means other partners are gaining ground. Compare it to China's share to distinguish genuine nearshoring from trade routed through Mexico. The twelve-month window smooths month-to-month noise and seasonal swings.

## What it does not say

It does not say whether the goods are made in Mexico or assembled there from inputs sourced elsewhere. It does not distinguish between industries, product categories, or the drivers of share changes such as tariffs, cost, or policy.
