Speaking as someone who works in a small company that designs and manufactures embedded devices, I can tell you that many of the 'minor' regulations which are not supposed to burden small businesses actually do. My (single) biggest annoyance is the conflict minerals reporting requirements which were supposed to apply to very large companies, but have been 'passed down' to smaller suppliers (as anyone with half a brain would have expected). There are many other KYC, CBP, and other regulations which have substantial impacts as well.
