In this market the certificate is not paperwork, it is the product. Uncertified material cannot enter an EU renewable fuel claim, and the price difference between certified and uncertified is usually far larger than any audit fee. We are not a certification body and we do not audit. What we do is explain honestly what certification involves, introduce you to our certification partner, and stay involved so the scope you end up with is the scope you actually needed.
Which scheme you need
Pick the wrong scheme, or the right scheme with the wrong scope, and you pay for an audit that does not let you do the business you wanted. That is the single most common and most expensive mistake we see, and it is entirely avoidable with one conversation before you sign the certification contract.
- ISCC EU, for biofuels and bioliquids placed on the EU market under the Renewable Energy Directive. If you want your material counted towards a member state obligation, this is the one.
- ISCC PLUS, for the non-fuel world: circular and bio-based polymers, chemicals, food and feed. This is the scheme behind a certified circular polymer claim, and therefore behind the value in plastic pyrolysis oil.
- ISCC CORSIA, for aviation under the ICAO scheme. Separate from ISCC EU and not interchangeable with it, which catches people out on SAF.
What the process actually looks like
It is less mysterious than people expect, and the timeline is more predictable than the cost.
| 1. Registration | Register with ISCC and choose a recognised certification body. The scope you declare here governs everything after. |
|---|---|
| 2. Preparation | Documented management system, mass balance bookkeeping, supplier self-declarations, GHG calculation method. |
| 3. Optional pre-audit | Worth it if you are starting from scratch. It turns audit findings into a to-do list instead of a failure. |
| 4. Certification audit | On site. Document review plus examination of how the system works in practice, not just on paper. |
| 5. Report and certificate | Audit report, then the certificate with your scope, product groups and validity. |
| Typical timeline | Roughly 6 to 10 weeks if you are reasonably organised. Closer to 3 or 4 months from a standing start with suppliers new to self-declaration forms. |
| Typical audit fee | Commonly in the region of EUR 2,500 to 6,000 for a single site trader, scaling with scope and supplier count. Your own preparation is the biggest variable you control. |
| Annual surveillance | Certification is not one and done. Budget for the recurring audit. |
What actually fails an audit
From what we see on the trading side, failures cluster in a few places and almost none of them are exotic.
- Mass balance that does not reconcile. Incoming and outgoing quantities, and the accounting period, have to line up. Spreadsheets that are rebuilt after the fact do not survive an auditor.
- Scope that does not cover the activity. Trading with storage is not the same scope as trading without. First point of collection is different again.
- Supplier documentation gaps. Self-declarations missing, incomplete or signed by someone with no authority to sign them.
- Traceability that stops at the first tier. Increasingly buyers and auditors want to see the collection base, not just your immediate supplier. See used cooking oil on why that scrutiny exists.
- GHG figures that cannot be reproduced. Using a default value and then claiming an actual value, or the reverse.
- Union Database entries that do not match the physical paperwork.
How we help, and what it costs you
We are a broker, so we are honest about our position here. We do not audit, we do not issue certificates, and we are not a consultancy dressed as one.
What we do is introduce you to Silk Road Certification in Poland, our certification partner, who handle ISCC EU and ISCC PLUS. We make the introduction, help you frame the scope so it matches the business you actually want to do, and stay reachable while it runs. We are paid a commission on that introduction, and we would rather say so plainly than have you wonder.
The reason we bother: a counterparty who cannot certify is a counterparty we cannot trade with. Getting people certified is not a side business, it is how the market we work in gets bigger.
Frequently asked questions
How long does ISCC certification take?
Commonly 6 to 10 weeks from application to certificate if your processes are reasonably clean. Closer to 3 or 4 months if you are starting from scratch and your suppliers have never filled in a self-declaration. The audit itself is short; the preparation is what takes the time.
What does ISCC certification cost?
Certification body audit fees commonly land in the region of EUR 2,500 to 6,000 for a single site trader, scaling with scope, number of sites and supplier count, plus the ISCC system fee and recurring surveillance audits. How well prepared you are is the biggest cost variable you actually control. Get a quote for your own scope rather than budgeting off a general figure.
What is the difference between ISCC EU and ISCC PLUS?
ISCC EU covers biofuels and bioliquids placed on the EU market under the Renewable Energy Directive, so it is what you need for material to count towards a member state obligation. ISCC PLUS covers the non-fuel world: circular and bio-based polymers, chemicals, food and feed. A certified circular polymer claim runs on ISCC PLUS, not ISCC EU.
Do I need ISCC to sell used cooking oil?
To sell into the EU biofuel chain, effectively yes: uncertified material cannot enter a renewable fuel claim. There is a real and growing market for non certified UCO in oleochemical, industrial and energy outlets, but it trades against different buyers at different levels. We will tell you plainly which market you are in.
Can you get us ISCC certified?
We do not audit and we do not issue certificates, so no broker can. What we do is introduce you to Silk Road Certification in Poland, our certification partner for ISCC EU and ISCC PLUS, help you get the scope right before you commit, and stay involved. We are paid a commission on the introduction and we say so up front.
What is mass balance in ISCC?
A chain of custody method where certified and non certified material may be physically mixed, but the certified quantity is tracked through the books and can only be sold on as certified once. Incoming and outgoing quantities and the accounting period have to reconcile. A mass balance that is reconstructed after the fact is the most common audit failure we hear about.
What is the most common reason an ISCC audit fails?
Scope and mass balance. Either the certificate scope does not actually cover the activity the company wants to do, which is discovered too late, or the mass balance does not reconcile because it was kept as an afterthought rather than as a live record.
