China’s drugs watchdog is soliciting public opinion on whether tighter supervision should be applied to the production of cosmetics.

On Tuesday, the China Food and Drug Administration (CFDA) outlined provisional changes to regulations, which would require cosmetics manufacturers to implement a mechanism to track products from warehouse production to the market.

The new rules would mean that Chinese companies would be legally obliged to label products with codes or lot numbers to facilitate product recalls if consumers report adverse reactions to goods.

The regulations would require manufacturers to deal with adverse reaction cases linked to their products with thorough investigations and assessments. The recall process should also be fully documented, the CFDA suggests.

For subcontracted products, the new rules require the contractors and subcontractors to clarify their responsibilities and draft an agreement to guarantee product quality.
