It's not allowed in any water lines used for drinking or cooking. I would read that as not allowed on hot water lines serving the kitchen for sure (and I suspect most plumbers would agree).
The warning on items from my plumbing supply house for lead containing items is prominent, pops up on each "add to cart", and says "This product does not comply with the “Safe Drinking Water Act,” which requires that products meet low-lead standards in order to be used in systems providing water for human consumption (drinking or cooking). This item is for non-potable (non-human consumption) water applications only."
It is allowed in hydronic heating, HVAC/R, and irrigation fittings (which of course don't have a human consumption element to them).
