See the summary on the USMA "laws" page Specifically as passed by Congress, section 1459 exempts drugs that fall under certain classifications (which I didn't track down definition of) Section 1453 allows FDA (over authority of Secretary of Health and Human Services) to exempt certain categories of products. Finally, I think medical devices would generally be durables and not fall in the category of consumables comsumed or used up.
Note that sec. 1459 exempts broad swaths of other things that fall under other Federal agencies. Also, note for drugs, net contents is often a count, and the strength of the pill is a descriptor. ________________________________ From: Team Metric Info <i...@metricrules.org> To: U.S. Metric Association <usma@colostate.edu> Sent: Fri, April 5, 2013 3:51:32 PM Subject: [USMA:52602] FPLA question Does anyone know how drug and medical devices became exempt from FPLA- they are metric-only correct? Did the FDA just give them a waiver or did someone seek congressional approval/ amendment? * Basic Requirements: The FPLA requires each package of household "consumer commodities" that is included in the coverage of the FPLA to bear a label on which there is: * a statement identifying the commodity, e.g., detergent, sponges, etc.; * the name and place of business of the manufacturer, packer, or distributor; * and the net quantity of contents in terms of weight, measure, or numerical count (measurement must be in both metric and inch/pound units). * Purpose of the Act: The FPLA is designed to facilitate value comparisons and to prevent unfair or deceptive packaging and labeling of many household "consumer commodities." * FDA: The Food and Drug Administration (FDA) administers the FPLA with respect to foods, drugs, cosmetics, and medical devices. The FTC administers the FPLA with respect to other "consumer commodities" that are consumed or expended in the household.
