The issue is that in many cases, this is not what is being sold on Amazon. There is good chinese brand/product (I love my chinese IEM), but when looking for many household items, you will find the white label, probably not compliant with local regulation, type of product. When it is not an outright scam.
I actually have a recent example : I do woodworking and for the last step of finishing some of the thing I build, I use a mixture of beeswax and linseed oil. Beeswax has been harder and harder to find locally. Not so long ago, every hardware shop had some. Now it has been displaced by synthetic product. So unless you know a local beekeeper, you are sol.
So, resigned, I went to Amazon. It had a trove of listing for "100% natural beeswax". Turns out, ALL of them are paraffin dyed to look like beeswax. You can report it to Amazon, they don't care. They will reimburse you, but never remove the listing.
