On and after January 1, 2006, each manufacturer or supplier shall furnish a certificate of compliance to the purchaser of a package or packaging component, even when the purchaser is also a supplier, stating that the package or packaging component is in compliance with the requirements of this article. However, if, pursuant to Section 25214.14, the package is exempt from the requirements of Section 25214.13, the certificate of compliance shall state the specific basis upon which the exemption is claimed. The certificate of compliance shall be signed by an authorized official of the manufacturer or supplier. A copy of the certificate of compliance shall be kept on file by the manufacturer or supplier of the package or packaging component.

(b)

A purchaser of a package or packaging component subject to subdivision (a) shall retain the certificate of compliance for as long as the package or packaging component is in use by the purchaser.

(c)

The manufacturer or supplier shall furnish to the department a copy of the certificate of compliance for each package or packaging component for which an exemption is claimed under Section 25214.14 at the time when a certificate of compliance for that package or packaging component is first furnished to a purchaser. If no exemption is claimed for a package or packaging component, the manufacturer or supplier shall provide to the department upon request a copy of the certificate of compliance for that package or packaging component.

(d)

If a manufacturer or supplier of a package or packaging component subject to subdivision (a) reformulates or creates a new package or packaging component, the manufacturer or supplier shall provide the purchaser, and, if the package or packaging component is exempt, the department, with an amended or new certificate of compliance for the reformulated or new package or packaging component.
