No, they provided no notice. They just sent us an email saying you can no longer sell these anymore without providing proof of these certifications. These our are new policy that we just implemented and provided this hidden "small" web link in seller central that shows you must have these or you will get your account and/or listings removed. They didn't conduct the test. Testing labs did. I think its because many peoples electronic batteries were catching on fire and the certification and internals used to pass the certification stops it.
The complete step-by-step guide to get back to selling today!
Say you list a pair of jeans, its fine to sell. Now 6 months later, you receive an email saying hey this link here that you cant even easily find shows you need a special jean dye certification in order to sell them further. If you cant show us this certification, then we will remove your listings in 2 weeks and you need to remove your inventory. Thats what happened. Its bs.
