The FDA requires all medical device manufacturers that design, produce and sell medical devices in the United States to follow 21 CFR 820.30. In general, the rest of the world follows ISO 13485 (7.3). As of the 2016 version of ISO 13485, for all intents and purposes, ISO 13485 (7.3) and 21 CFR 820.30 are equivalent. The following table provides a comparison between FDA and ISO 13485 requirements. The significant differences between design control regulation 21 CFR 820.30 and standard ISO 13485 (7.3) are bolded in the following column.
