Think Novel Psychoactive Substance (NPS) is a better term then. Research chemicals imply that the chemical is available to research without restriction. I could undoubtedly buy things that are legal here from abroad but if they are legal here they are generally on sale here.
If they aren’t available here the you have no choice to buy from oversees but if it’s banned by customs then it can’t be an RC, that’s where the legal part of legal high comes from.
