Certifications and Compliance
Our Certifications
GOTS — Global Organic Textile Standard
GOTS is the most recognised certification in sustainable garment manufacturing. It covers the entire production chain - from raw fibre to finished garment - and requires that organic materials are handled, processed, and dyed according to strict environmental and social criteria.
Holding GOTS certification means we can legally produce and label garments as organic. For brands selling into the UK, EU, and US markets where organic claims are increasingly scrutinised, this is not optional - it is a commercial requirement.
OEKO-TEX Standard 100
Every fabric we use is independently tested and certified free from harmful substances under OEKO-TEX Standard 100. This covers pesticide residues, heavy metals, formaldehyde, and over 100 other regulated substances.
For brands selling childrenswear, sportswear, or any product in direct contact with skin, OEKO-TEX certification gives your buyers confidence that the product meets safety standards before it reaches retail.
SEDEX — Supplier Ethical Data Exchange
We are a registered SEDEX member and operate with full supply chain transparency. SEDEX membership means our labour practices, health and safety standards, and environmental performance are independently verified and available to our brand partners.
Most UK and European retailers require SEDEX membership from their suppliers. We are already in the system.
Amfori BSCI
Our factory operates in compliance with Amfori BSCI (Business Social Compliance Initiative) standards, covering fair wages, safe working conditions, and ethical labour practices across our production facility.
Factory Audits and Brand Approvals
Certifications tell one part of the story. Brand audits tell the other.
Istanbul Tekstil has passed factory audits from some of the most demanding retail groups in the world:
-
Tesco
-
Primark
-
Puma
-
Abercrombie & Fitch
-
Tommy Hilfiger
These audits cover factory conditions, production processes, quality control systems, and social compliance. Passing them is not straightforward — and maintaining compliance across multiple brand standards simultaneously requires consistent operational discipline.
If you are a brand that works with retailers at this level, or aspires to, our facility already meets their supplier requirements.
What This Means for Your Brand
Working with a certified, audited manufacturer protects you in several ways.
It removes the compliance risk of sourcing from uncertified factories — a risk that has become increasingly visible as retailers apply pressure on brands to demonstrate responsible sourcing. It gives you documentation you can show to your own buyers, retail partners, or investors. And it means that when a retailer asks for your supplier audit report, you have one.
We can provide copies of all current certificates on request. If you have specific retailer requirements or a compliance checklist from your buyer, send it to us and we will confirm whether we meet it before you commit to sampling.
