The TSCA section 8(a) Nanotechnology Reporting and Recordkeeping Requirements Rule came into effect on August 14, 2017, and also released final guidance toward compliance with the rule. The rule includes reporting and recordkeeping obligations for current and future manufacturers and processors of certain existing chemical substances produced at the nanoscale. Under this new rule, one-time reporting and recordkeeping are required for certain chemical substances when they are manufactured or processed at the nanoscale.
