Can you purchase needles from Mexico and take to the US?

No. It is illegal to import needles into the United States without a permit from the Food and Drug Administration (FDA). Needles are considered medical devices, and they must meet certain safety and quality standards before they can be sold in the United States. Importing needles without a permit is a federal offense, and you could be subject to fines, imprisonment, or both.

If you need to use needles for medical purposes, you should talk to your doctor or a pharmacist about how to obtain them legally.
