The beauty of a standard like BS1088 is consistency regardless of where its made, you can visually inspect
plywood and determine if it conforms to the standard in every way EXCEPT the glue line. For this you will need to do your own boil test. Not all BS 1088 is Lloyds certified but that does not mean in any way that it is inferior. I have used Hydrotek meranti
plywood which I believe is made in
Indonesia, its as good as any other BS1088 meranti, I don't think it is Lloyds certified but I could be wrong on that.
On the
epoxy there are a lot of lower cost ones that are great but I would suggest
buying a smaller batch and trying it before committing to a bigger quantity where the real cost savings come from.
