How We Screen Compostable Bag Suppliers for the EU & US – 3 Layers, No Fluff

If you're sourcing compostable bags, food films, or paper-based eco-packaging for the EU or US market, you already know: everyone claims to be "green."

So how do actual procurement managers separate real partners from the rest?
We use a simple three-layer filter. Not a spreadsheet nightmare. Just practical sanity checks.

Here's what we actually look for – and where our current suppliers (including us, at Torise) stand inside those three layers.

Layer 1 – Must have The "No-Go" Filter

Missing these = you're out before we finish coffee.

This is not about being "best." This is about not being eliminated in 30 seconds.

For any compostable bag or food-grade film entering Europe or the US, the baseline is brutal:

• FSC – if your bag has any paper component (window, handle, label), most EU supermarket buyers won't even open your sample without FSC Chain of Custody.
• BRC – for food-contact films and bags. No BRC = high risk of being stopped at retailer audit.
• EN13432 (Europe) or BPI (US) – these are the industrial composting passports. No certificate from a recognized body = your bag is legally not "compostable" in most EU countries.
• ISCC PLUS – increasingly required for mass-balance bio-circular or bio-based materials, especially for brands with Scope 3 targets.

Layer 2 – Shortlist decider Where 80% of "certified" suppliers fail

Layer 1 gets you to the table. Layer 2 decides if you stay there.

System certifications – not for marketing, for consistency

We check: ISO9001 (quality), ISO14001 (environmental management of your factory), ISO45001 (occupational health – because unstable workers make unstable bags). These three tell us: do you run a professional factory, or a shed with a printer?

Social compliance – BSCI or equivalent

European buyers won't admit this openly, but they quietly filter out suppliers without BSCI or SMETA. Not because they love audits – because their own CSR report requires it.

We hold: ISO9001, ISO14001, ISO45001, and BSCI (all current, all on our certificate page).

The real killer: traceability + test reports

Here's where it gets human. A certificate from 2022 means nothing if you can't show:

• Batch-level traceability from resin to finished bag
• Third-party test reports (not in-house) from the last 12 months
• Mass balance records (ISCC PLUS already requires this – good)

What we do: Every batch of compostable resin is logged. Every finished product batch has a retained sample. We don't guess – we track.
For the US: BPI-certified products.
For Australia: AS 5810 / AS 4736 (home and industrial compostable).
For Europe: full EN13432 with supporting OWS or TÜV reports.
Most Layer-1-only suppliers stop here. They have a logo but no paper trail. We send the PDFs within 24 hours – not "let me ask our lab."

Layer 3 – The real "order" decision Certificates don't ship. Factories do.

You'd be surprised how many buyers choose a slightly less-certified supplier at Layer 3 – because the "perfect" one can't deliver reliably.

Delivery capability

Do you have dedicated compostable production lines (not shared with conventional plastic)?
What's your realistic MOQ and lead time for Europe? Can you handle mixed pallets (different sizes, same container)?

Stability

Same resin formula as last year? (We've seen suppliers switch to cheaper PBAT without telling buyers.) Same mechanical properties across seasons?

Service that doesn't exhaust us

Do you proactively flag lead time issues, or wait for us to chase? Can your technical person speak to our technical person – not just a sales rep?

Price structure – be honest

Here's what smart buyers actually respect: not "lowest price." But predictable pricing: bio-based vs fossil-based breakdown, ocean vs air freight options, payment terms that match your raw material purchasing cycle.

We don't win every Layer 3 comparison on price. But we win on transparency – and that's what keeps buyers coming back for year two.

So where does Torise actually sit across these three layers?

Let me save you the hunting. On our certificate page you'll find:

One last thing – and this is the honest part

Not every buyer needs every certificate. But every buyer needs a supplier who understands which layer they are failing at.

If you're a European or US buyer reading this:
• Layer 1 missing? Don't waste your sample request.
• Layer 2 weak? Ask for batch traceability – watch them hesitate.
• Layer 3 solid? That's your long-term partner.

That's how you filter noise. And that's how we choose to work.
