Another interpretation of the question may be "Where is the NRTL requirement strictly enforced?" (which is a much larger list than where it is required.) Where can you get away without a NRTL mark? That depends in part on the product, the market, and the distribution scheme.
Which brings this to mind- "Is a law a law if it is not enforced?" (Many politically controversial issues come to mind here.) I have had many clients who actually want to waive tests based on the argument "We've been selling these for years, and have had no complaints yet." It is not uncommon to be able to sell laboratory equipment, with a CE mark only, all over the US. Even some medical equipment (which truly surprised me). Basically, if the client (or reseller) doesn't care, and the electrical inspector doesn't see it, it can be sold and used without a NRTL mark. The same logic can be used in illicit drug trafficking as well. (If I don't get caught, I'm not breaking the law). I am not suggesting that any product to be sold in the US not be "NRTL'ed", but just expressing another viewpoint. Besides the fact that my employer makes money when we sell a NRTL job, my risk vs reward mindset tells me the cash saved now (a few $k - not much reward) ain't worth the potential injuries, deaths, and lawsuits (where the risk amount depends on your company's assets). NRTL it, and the question is moot. Sam This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
