WASHINGTON — The North American Free Trade Agreement may not be a topic of frequent discussion in your household, but the trade pact probably plays a big role in your daily life.

From the clothes you wear to the food you eat and the car you drive, many everyday products traveled on winding journeys across international borders before landing in your closet, your refrigerator or your driveway.

Many of their paths are set by Nafta, a 24-year-old agreement that President Trump has called a “disaster.” The president pledged to withdraw from the pact entirely if Canada and Mexico don’t agree to his demands to reshape the agreement.

Nafta has had a profound effect on the three countries. It has encouraged United States companies to expand across the continent by abolishing the tariffs charged on products moving across borders. It has strengthened some industries, and hollowed out others.
