How to check ISCC CORSIA self-declarations for used cooking oil
Use a receiving checklist to verify current ISCC CORSIA UCO self-declarations, hold unsupported claims and prepare for a collecting point audit.
If you collect used cooking oil (UCO) for a customer requiring ISCC CORSIA, check that each point of origin has the current applicable UCO self-declaration before counting its oil towards a CORSIA claim. If the version or source link is uncertain, hold the claim while you verify the evidence.

Check what the buyer requires
Ask the buyer to specify the scheme and sustainability claim for the shipment. This checklist is for a collecting point handling UCO under ISCC CORSIA for an aviation fuel supply chain, such as HEFA. For FAME biodiesel or HVO renewable diesel sold under an ISCC EU claim, check the applicable ISCC EU documentation separately. The intended fuel alone cannot establish the scheme.

Run a receiving check at the collecting point
ISCC’s 29 October 2026 update says current CORSIA self-declaration templates are mandatory and previous versions have been withdrawn. Download the current UCO template through the ISCC client section and use it to check your supplier records. The following checks are a practical way to organise the evidence. Official ISCC System Updates
- Identify the source. Match the point of origin and site in the declaration to your sourcing list and collection record.
- Check the document. Verify the scheme, current template, completion and signature against the applicable instructions. Keep a copy linked to the source record.
- Link the delivery. Use the collection reference and quantity to trace the receipt into your stock and mass balance records.
- Control exceptions. Record the reason for the hold and assign someone to confirm whether the affected oil can support the claim before including it in a sustainability declaration.
Worked example with an old supplier form
A restaurant’s collection ticket matches the weigh-in record, but the declaration on file is an earlier CORSIA version. The collecting point records the physical receipt and holds its CORSIA claim pending review. Its compliance lead obtains the current form, checks the source details and asks the certification body how to treat the affected receipt if eligibility is uncertain. The lead records the decision and samples the next collection to confirm the revised check works. A replacement declaration alone does not establish eligibility for earlier deliveries.
Prepare one complete sample for the audit
Bring the source record, declaration, collection ticket, receipt quantity and corresponding stock or mass balance entry. Include an exception and its resolution where available.
