(a) Issuance.--As soon as feasible but not later than two years after the effective date of this act, a certificate of compliance stating that a package or packaging component is in compliance with the requirements of this act shall be furnished by its manufacturer or supplier to its purchaser, provided, however, where compliance is achieved under an exemption provided in section 302(2) or (3),¹ the certificate shall state the specific basis upon which the exemption is claimed. The certificate of compliance shall be signed by an authorized official of the manufacturing or supplying company. The purchaser shall retain the certificate of compliance for as long as the package or packaging component is in use by the purchaser to package products. A manufacturer of packaging or packaging components may issue one certificate of compliance to each customer covering every package or packaging component sold to that customer. A copy of the certificate of compliance shall be kept on file by the manufacturer or supplier of the package or packaging component. Certificates of compliance or copies thereof shall be furnished to the department upon its request and to members of the public.

(b) Subsequent changes.--If the manufacturer or supplier of the package or packaging component reformulates or creates a new package or packaging component, the manufacturer or supplier shall provide an amended or new certificate of compliance for the reformulated or new package or packaging component. The requirement to provide an amended certificate will not be triggered by changes in size, shape and label copy unless such changes affect compliance hereunder.
