In US, as well. In fact, all kinds of things that have to do with both active IR, and protection against it, are regulated.
For example, there's a popular firearm (and other things, technically, but it's mostly used for firearms) coating called Cerakote. Comes in a bunch of colors, including those commonly used for camouflage - indeed, you can mix and match to create some very impressive patterns. Example:

This is available to civilians, and pretty popular - mostly for aesthetics, but it does work well as a camouflage. The catch is that, being an epoxy polymer coating, it reflects NIR really well - so for someone observing through a night vision device, these things basically glow, especially if an infrared illuminator is also used.
But Cerakote also does have a version that was specifically designed to reduce the near-infrared signature to the point where it works just as well as camo in NIR, as it does in visual spectrum. Except it's only available to military and police - and I believe this is, in fact, because of some law that restricts them from offering it on civilian market.
