ISCC PLUS: Alternative Feedstock and Supply-Chain Claim Review
ISCC PLUS is often used for supply-chain management related to bio-based, circular, recycled, and renewable feedstocks, supporting documented review of feedstock source, certified site, chain of custody, and claim boundary. For chemical, plastic, packaging, textile, and related material companies, the key is not a general low-carbon or circular-economy statement. The key is to confirm whether feedstock, site, certificate, and listing claim correspond to each other.
Evidence Review Points
| Record | Purpose | Common risk |
|---|---|---|
| Feedstock scope | Confirm the specific type of bio-based, circular, recycled, or renewable feedstock involved | Feedstock category and claim basis are mixed |
| Site certificate | Confirm whether production, trading, or storage site is within certificate scope | Certificate holder does not match the actual supply site |
| Chain of custody | Review supply-chain model, purchase records, transfer documents, and sales documents | Purchase batch, shipment batch, and claim ratio cannot be matched |
| Mass-balance records | Support input, output, inventory, and allocation-ratio accounting | Ledger period, quantity, or allocation rule is inconsistent |
| Listing and packaging wording | Confirm authorization for standard name, mark, and material claim wording | Claim scope is expanded beyond covered scope |
Claim Boundaries
- State whether the claim applies to feedstock, intermediate, finished product, site, or supply-chain batch.
- Do not expand evidence from one site or feedstock batch beyond the covered scope.
- After supplier, site, feedstock category, or mass-balance period changes, review the evidence chain again.
- Packaging, e-commerce images, sales files, and advertising assets should use the same authorized expression.
Green Ark's Recommendation
Green Ark (Shenzhen) Certification Co., Ltd. recommends building a checklist that links feedstock scope, site certificate, chain of custody, mass-balance ledger, and listing wording. ISCC PLUS-related claims are suitable for customer-facing pages only when supply-chain evidence and claim boundary are consistent.
