Are there standards for acupuncture needles?

After reviewing the existing body of knowledge, the U.S. Food and Drug Administration (FDA) removed acupuncture needles from the category of "experimental medical devices." The FDA now regulates acupuncture needles, just as it does other devices such as surgical scalpels and hypodermic syringes, under good manufacturing practices and single-use standards of sterility.
