Indonesia has issued a revision to the legal instrument underpinning its mandatory sustainable palm oil scheme, strengthening the legality verification component, particularly the linkage between certification and the underlying plantation permit and spatial planning status. The change matters because legality of land tenure has been the most contested element of ISPO credibility, especially for estates with permit histories that intersect disputed forest-area classifications.

Under the revised framework, certification bodies are expected to give greater weight to permit conformity and to the resolution of land-status overlaps before issuing or renewing certificates. For operators with clean documentation the practical effect is incremental. For estates carrying unresolved permit or spatial-plan conflicts, the decree raises the prospect of certification delay or denial, which in turn affects their position in supply chains where buyers require certified provenance.

The broader significance is interoperability with external due diligence regimes. A scheme whose legality module is demonstrably stronger is easier to defend in market access discussions and in benchmarking exercises conducted by import jurisdictions. The open question is enforcement consistency across the certification body network, since the decree’s value depends on uniform application rather than formal text alone.
