Exactly the point I made the retailer. They were pleasant and said they would have their product team look into it.
However... looking in to it later today I found the manufacturer (not the retailer) has doubled down, and is producing a "for pizza oven" pellet as well as the boiler pellet I saw before. The packaging doesn't mention wood type, but they are Scottish, and the majority of the wood up there is spruce, pine and similar. Then I found this on one of their websites:
https://www.woodfuel.coop/wood-fuel-news/pellets-for-pizza-ovens-myth-busting/"Why you don’t have to use Hardwood pellets for pizza ovens……"
Their "myth-busting" is all about calorific values and ash; and they don't address the sap issue at all.
Now, perhaps you might get away with it with a pizza over running hot (although I wouldn't want to), but the new packaging comes out and says "suitable for all pellet grills, ovens and stoves".
The big problem is that there isn't the same level of awareness over here, and I fear a few people are going to have their BBQs ruined.
