Thank you for the question.
In general, what we would anticipate would trigger a request like that would be a suspicion of non-compliance. If we think, for example, of a product such as children's jewellery, in which we think there may be a problem with the level of lead in it, we might ask suppliers—that provision, I believe, is related only to importers and manufacturers, so it stays at a higher level of trade—to provide test results to verify that their products are within the regulated limits.
That's probably a good example, or one of the best examples I could give you.
