Modification

Modifications

As outlined in Section 8 of BPI's Commercial Compostability Certification Scheme and Home Compostability Certification Scheme, BPI certificate holders are required to notify BPI of all alterations to the manufactured item without delay. BPI will decide the extent to which testing must be performed and whether the change is significant. The respective test report(s) shall be sent to BPI by the approved testing laboratory. 

The type and scope of supplementary testing will be determined by BPI in individual cases in coordination with BPI’s Technical Reviewer. This is for small changes, such as adding printing inks to a previously unprinted item, changing a resin grade or supplier for PLA or PBAT, or adding a new manufacturing site for certified products. 

Companies wishing to add home compostability certification to their existing certificates will also need to submit a modification.  The cost to do this ($1,500 USD) differs from the other types of modifications that are mentioned on this page. 

Link to the BPI Member Company’s Product Catalog Listing on the BPI Website: BPI-certified products are listed in a searchable catalog on BPI’s website. This catalog allows the public to search for and verify BPI-certified products. Product listings are populated with the information from the product worksheet and also appear on the BPI Certificate.

Testing

The type and scope of supplementary testing required for a modification will be determined by BPI and BPI’s technical reviewer. Based upon the information provided, BPI and BPI's technical reviewer will determine if the requested changes qualify for a modification or require a full New Certification (in which case the expiration date would be extended, and additional fees assessed).
