Washington (CNN) If President Donald Trump follows through on his threat to close the US-Mexico border, it would disrupt the flow of $1.7 billion of goods daily to store shelves and factory floors -- including not just avocados, but beer and car parts, too.

But shutting down the border would do more than cut into the country's guacamole supply. Strawberries, tomatoes and bell peppers are sent north from Mexico. Americans also buy more than $4.6 billion a year in beer, wine and alcohol -- including tequila -- from its southern neighbor, according the the Census Bureau.
