Every certification on this page can be checked against a public registry. That is the point.
Most supplier compliance pages are a row of logos with nothing behind them. This one names each standard, says plainly who holds it — us, a nominated mill, a group company, or nobody yet — and links you to the registry where you can confirm it without taking our word for anything.
Four headline credentials — and it matters who holds which.
A certificate issued to a fabric mill is not a certificate held by your supplier, and a list that presents both the same way is hiding the difference on purpose. Here is ours, unflattened.
Social compliance and ethical-labour auditing across the supply chain. Graded A to E rather than pass/fail, and the standard European buyers ask for most.
How to check it: Ask for the amfori audit ID and audit date. Grades expire — a 2019 'A' tells you nothing about the floor today.
amfori sustainability platformLawful, humane and ethical manufacturing, certified through a US-based programme built specifically for apparel and sewn products. Awarded Platinum, Gold or Silver.
How to check it: WRAP issues a dated certificate rather than a grade, so it is the easiest of these to check — take the certificate number and confirm the holder name and expiry.
WRAP certified facility searchTextiles tested for harmful substances at every component level — shell, trims, linings and thread, not just the main fabric.
How to check it: Every certificate carries a label ID. Enter it in the OEKO-TEX label check and it returns the holder, the article covered and the validity date.
OEKO-TEX label checkCertified organic fibre content plus environmental and social criteria through the whole chain. Runs on our organic-cotton programmes through Collective Studio, from 100 pieces.
How to check it: GOTS maintains a public database of certified entities. Search the licence number — organic claims are the most-faked in this industry precisely because they carry a premium.

No, we are not LWG certified. Here is what that actually means.
Leather Working Group certification audits tanneries — the facilities that turn raw hide into finished leather — on water, energy, chemical management, waste and traceability. It does not audit the workshop that cuts and stitches a finished jacket. So it is not a credential a leather-goods maker or a buying house can hold in place of its supplier, and anyone presenting it that way is describing something that does not exist.
It is also the most consequential standard in this trade. Without a certified source, a leather programme is effectively invisible to the large European and North American buyers who now require verifiable sustainable sourcing before they will open an account.
The Bangladeshi position is genuinely difficult, and worth knowing before you compare quotes. When the tanneries moved from Hazaribagh to the Savar estate at Hemayetpur, the central effluent treatment plant built to serve them was never brought fully into operation — and effluent treatment is a scored section of the protocol. A tannery inside the estate is capped by infrastructure it does not control.
That is why the few Bangladeshi operations holding LWG certification sit outside the estate, running their own treatment. Government has signalled the certification will become mandatory for the sector. Until the CETP question is genuinely resolved, a Savar-based LWG claim deserves real suspicion.

What we do instead: we name the tannery your hide comes from, give you its audit position as it actually stands, and route through a certified source where your programme requires one and the economics allow it. Our leather is bovine, ovine and caprine — a by-product of the meat industry, never exotic. If LWG-certified material is a hard requirement, say so at enquiry stage: it changes the sourcing route and it changes the price, and you should hear that from us before you commit to a quantity, not after.
The standards that govern hide, before it ever reaches a sewing floor.
The environmental burden in leather sits upstream, at the tannery. These are the protocols that regulate it — what each one covers, and where we stand against it.
The global benchmark audit for leather manufacturers, scoring tanneries on water, energy, chemical management, waste and traceability to Gold, Silver or Bronze. LWG audits the tannery, not the workshop that stitches the finished bag — no leather-goods maker can hold it in place of its supplier.
How to check it: LWG publishes its certified list openly. Any supplier claiming a medal can be checked in under a minute, and in Bangladesh the list is short enough that the claim is unusually easy to falsify.
LWG certified supplier searchThe leather-specific counterpart to STANDARD 100 — tests finished hide and leather articles for harmful substances, covering REACH Annexes XIV and XVII, the ECHA SVHC candidate list, US CPSIA and the EU POPs regulation in one certificate.
How to check it: Same label-check mechanism as STANDARD 100. Worth requesting where a retailer's own restricted-substance list is stricter than baseline REACH.
OEKO-TEX LEATHER STANDARDThe EU restriction that actually stops leather at the border. Entry 47 caps hexavalent chromium in leather that contacts skin at 3 mg/kg, and the direction of travel is tighter still, toward 1 mg/kg. Cr(VI) is not added during tanning — it forms when trivalent chrome oxidises in badly controlled finishing or storage, which is why it is a process-control problem rather than a recipe problem.
How to check it: Ask for a current Cr(VI) test report from an ISO 17025 accredited lab against the hide going into your order — not a generic certificate for a different article from two seasons ago.
Restricts hazardous chemistry at the input stage rather than testing for it in the finished article, plus wastewater guidelines for the facilities discharging it. Conformance signals a tannery controls its chemical supply chain, which is what actually lowers restricted-substance failure risk downstream.
How to check it: OEKO-TEX ECO PASSPORT is accepted by ZDHC at Levels 1 to 3, so an ECO PASSPORT on the chemical inputs is a practical proxy where full MRSL conformance data is not available.
ZDHC Roadmap to ZeroThe Italian certification body for the leather sector, covering tannery quality systems, social accountability and — the part buyers increasingly ask about — traceability of finished leather back through the chain.
ICEC certificationsA transparency-dashboard audit covering environmental, social and governance impact across the leather supply chain, structured to be reachable by smaller facilities that cannot absorb a full LWG audit cycle.
Sustainable Leather FoundationLaunched by COTANCE in 2022, this is LWG, ICEC, OEKO-TEX, the Sustainable Leather Foundation and Textile Exchange agreeing a common set of essential traceability requirements so assessments become mutually recognisable. Worth tracking: it is the reason traceability is moving from a scored bonus to a critical section of the LWG leather manufacturer standard.
LWG traceabilityGoverns trade in exotic skins — reptile, and anything from a listed species. We do not work in exotics: our leather programme is bovine, ovine and caprine hide, all of it a by-product of the meat industry. If your range needs exotic leather, we are the wrong supplier, and we would rather say so now.
CITES species databaseFor ranges built on PU and non-animal alternatives rather than hide. A labelling certification rather than an environmental one — it certifies the absence of animal material, and says nothing about the polyurethane's own footprint.
PETA-Approved VeganArranged on request, in the name of whoever actually holds them.
Where an order requires one of these, we route production to a partner facility that holds it and pass the certificate through in that facility's name. Tell us at enquiry stage — it changes which factories can take the order.
A 2-pillar or 4-pillar ethical audit methodology — labour, health and safety, plus environment and business ethics in the 4-pillar version. The standard UK retailers ask for, alongside BSCI for the EU.
SedexQuality management systems. Certifies that documented process exists and is followed — not that the garment is good. Useful as evidence of repeatability across seasons, which is a different question from whether a sample passed.
Environmental management systems. Increasingly requested alongside ISO 9001 by buyers whose own reporting obligations now reach into their supply chain.
Social Accountability International's labour standard — the most demanding of the social audits here, built around a management system rather than a point-in-time inspection.
SAI SA8000Cascale's Facility Environmental Module and Facility Social & Labor Module — self-assessment plus third-party verification, and the framework most large brands now use to score a facility internally.
Textile Exchange standards verifying recycled content and its chain of custody — relevant to recycled polyester shells, linings, and increasingly to hardware and packaging.
Textile Exchange standardsNot a factory certification but the accreditation that makes a test report mean anything. Physical and chemical testing routed through accredited labs — SGS, Intertek, Bureau Veritas or TÜV — so results hold up with your compliance team.
Ten minutes with these registries beats any claim on this page.
A certificate image pasted into a sales deck costs nothing to fake and nothing to catch unless somebody checks. Check the holder name matches the company actually making your goods, that the scope covers your product type, and that it has not expired.
