Do they require individually mentioning all the products/brands (which would greatly increase recall metrics, making the placement more valuable to the buyer) or is it just a blanket "supported by product placement"? The latter is what we have here in Germany and I find it rather unfortunate that it covers such a wide range of advertising influence: from lower rates for all that IKEA stuff one would need to create realistic backdrops, to full blown product praise like you would see on a shopping channel.
