I still believe the guitars were destroyed because they didn't meet RHOS and they couldn't apply CE marks. There's a paper trail and lots of documentation. If that stuff is not up to snuff, you can't ship.
What are the restricted materials mandated under RoHS?
The substances banned under RoHS are lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), and four different phthalates (DEHP, BBP, BBP, DIBP).
Do you want that in your schools? If you can't certify your product does not contain these things below acceptable limits you can't sell or give it away to the poor.
