16 mm (Tasmanian Oak)

The difficulty (IMHO) with using biscuits in thin timber, especially softwood, is that the bicuits are meant to swell once glued into the joint. In soft thin timber and usually (but not always) hardwood this sweling causes the timber to split. Of course you can always run a thicker board through the thicknesser after you've biscuit joined it.

I have used biscuits in 12mm MDF with no problems.

10mm would be about as thin as I'd go... FWIW.

I used a 2mm slot cutter and sanded some biscuits to suit on 6mm timber once as an experiment and it worked very well

I didn't think the swelling would be enough to cause the timber to split, never gone under 14mm, never had the need but might try just to see what happens.

Iv done 8mm timber heaps. Trick is a "sharp" cutter, then soak the biscuits for a few minutes first and let them expand and dry, then sand back to slip snugly but not tight in the slot. They dont need to expand just as a tennon dosnt expand in a mortice. But the most important thing is to let the join and biscuit inside to dry completly before sanding or planing back. If the timber dose swell you will sand a small "hump" off the top and when it dries you will get a visible "dip" that shows when you laquer it
