Yes or No?
Here lots of our clients asked us about this question.
Like: do you have the ROHS certificate for the piezoelectric ceramic?
When we searched google about the question. the answer is like this.
When it comes to specific applications and materials, the RoHS directive includes a short list of “exemptions” to the standard which allows manufacturers and end-users to include limited, yet potentially hazardous substances if alternatives are not readily available or equally as effective. One exemption (exemption 7-C) concerning the use of lead(Pb) in piezoelectric ceramics presently exists allowing lead(Pb) to be used in the manufacture of PZT (lead-zirconate-titanate) type piezoelectric ceramic products.
It is still unknown at this time if exemption 7-C will be extended, or if electronic equipment containing lead(Pb) will be able to be sold in the European market after July 2021.
So, We’ll keep updating the information once we have it.
