Sustainable and organic clothing manufacturer in Bangladesh

From 27 September 2026, a green claim has to be provable

The rules changed under brands’ feet. Directive (EU) 2024/825, the Empowering Consumers for the Green Transition Directive, applies from 27 September 2026. It bans generic environmental claims such as “eco-friendly”, “green” or “climate neutral” unless you can demonstrate recognised excellent environmental performance, and it bans sustainability labels that are not based on a certification scheme or established by public authorities. Product-level carbon neutrality claims resting on offsetting rather than real reductions in your own supply chain are blacklisted outright.

The UK has taken the same direction through the Competition and Markets Authority’s Green Claims Code, and in the United States the FTC’s Green Guides govern environmental marketing. The practical effect is identical everywhere: the sentence on your product page has to be traceable to a document in your file. That is a sourcing job, and it starts at the fabric, not at the copywriting stage.

The certificates that back a claim

There is no single “sustainable” certificate. Each standard proves one specific thing, and mixing them up is how brands end up making claims they cannot defend. The table below sets out the ones that matter for clothing made in Bangladesh, the threshold each one requires, and where you can check a certificate yourself rather than taking anyone’s word for it.

Read it with one question in mind: what exactly do I want to be able to say on the label? Work backwards from that sentence to the standard that proves it, then to the fabric that carries it.

Scope certificates and Transaction Certificates are not the same thing

This is an easy mistake to make, and it is expensive. A scope certificate says a factory or mill is certified to a standard and lists what it may process. It does not say your goods were made under it. A Transaction Certificate, issued per shipment, is what ties your specific order to certified material.

If you intend to print “GOTS certified organic cotton” on a label, you need the Transaction Certificate for that shipment. Without it, the claim is unsupported, and a retailer’s compliance team or a regulator will treat it that way. Plan the certificate chain before fabric is booked, because a TC cannot be created retrospectively for goods that were not run as certified.

• Check the factory and the mill each hold a valid scope certificate for the process they perform
• Confirm the certificate is current, and covers the product category you are making
• Book the fabric as certified material, in a certified run, not as a like-for-like substitute
• Collect the Transaction Certificate for your shipment and keep it with the order file
• Verify the certificate number in the issuing body’s own public database before you make a claim

The paper trail for one certified shipment

A GOTS claim on a finished garment rests on a chain of documents, and the last link, the Transaction Certificate, only exists after the goods have left the factory. That surprises brands who expect it with the samples. The certificate lists each shipment with its shipment date, shipping document number and sales invoices, so it cannot be written before the goods are shipped; what you can check before production are the scope certificates of the factory and the mill.

GOTS also fixes who can appear on it. Under its Policy for the Issuance of Transaction Certificates, version 3.0, which has applied since 1 July 2022, a Transaction Certificate is issued only by an approved certification body, only to a seller holding a valid scope certificate on every shipment date, and only by the body that issued that scope certificate. The buyer does not have to be certified. So agree in writing, before fabric is booked, which certified company will be named as the seller and who as the buyer, because a gap in that chain cannot be repaired later.

Today’s certificate is a digitally signed PDF, numbered by the certification body. It names the certifier, the seller with its scope certificate and licence numbers, and the buyer; gives the gross, net and certified weights in kilograms; lists the input Transaction Certificates; and records each shipment with its date, shipping document number, invoices and consignee. Check it with the authentication method the certifier lists on the GOTS page of approved certification bodies, then file it with the invoice. A new version 4.0 of the procedure, released on 15 May 2026, applies to every certificate issued from 1 January 2027, and certifiers may adopt it earlier. Under it, every certificate is issued through Global Trace Base, the GOTS database, which assigns its number, and the certifier must verify the documents behind each figure and reconcile the volumes before issuing it.

What we can honestly say about our role

CMB Sourcing Ltd. is a manufacturer and buying house. We make knitwear and caps in our own factory, but no GOTS, GRS or OEKO-TEX certificate for it is published on this site yet, so we claim none: each certificate belongs to the factory or mill that holds it, and we give you its number to check. Anyone who tells you their agency is “GOTS certified” is either a processor, or is describing something that does not mean what you think it means.

What we do is choose the supply chain, name the factory to you in writing before production starts, give you its certificate numbers so you can check them in the issuing body’s database, and manage the paperwork through to the Transaction Certificate for your shipment. If a certified option does not exist for what you want at the quantity you want, we will tell you that instead of finding a form of words.

Materials, and their honest trade-offs

Every “better” fibre is better at something and worse at something else, and a brand that understands the trade-off makes stronger claims than one that does not.

Certified organic cotton removes synthetic pesticides and fertiliser from the growing stage and comes with a chain of custody you can prove; it costs more and, per hectare, tends to yield less. Recycled polyester diverts bottles or textile waste from landfill and performs well in activewear; it sheds microfibres like any polyester, and “recycled” says nothing about the dyeing chemistry, which is what ZDHC and OEKO-TEX cover. Recycled cotton has shorter fibres, so it is normally blended with virgin or organic cotton for strength, and the blend must be stated accurately on the composition label. Lyocell and linen bring genuinely different properties, and their own supply constraints in Bangladesh.

The Better Cotton Initiative (BCI) deserves a specific warning, because it is widely misunderstood. It is a farm-level programme sold mostly on a mass-balance basis, which means your garment may not physically contain any BCI Cotton at all. Under the new EU rules, a claim that implies physical content when the system is mass balance is exactly the kind of statement that will be challenged.

The factory itself, not just the fabric

Fabric certificates say nothing about the building your garments are sewn in. Bangladesh is unusual here, and it is one of the few places where the sustainability story is genuinely better than the country’s reputation: the country had 291 LEED-certified garment factories, according to BGMEA’s website on 23 September 2026, rated by the US Green Building Council on energy, water, materials and indoor environment. You can look up any factory named to you in the USGBC project directory to see whether it is LEED-certified.

Beyond the building, the things worth asking about are effluent treatment for wet processing, chemical management through ZDHC, and energy and water data through Higg FEM where the factory reports it. Ask which of these apply to the factory chosen for your order, and for the documents that exist. We do not send you a certificate belonging to a factory your goods were not made in, which is a practice you should test any supplier for by asking whether the certificate number matches the factory named on your invoice.

What it costs, honestly

Certified production costs more, and the honest answer to “how much more” is that it depends on the fibre, the quantity and the season, so we quote it rather than publish a percentage we cannot stand behind. What we can tell you is where the cost actually sits, so you can decide what to buy.

Certified fabric carries a higher mill price and usually a higher minimum order, which is the constraint that bites smallest brands hardest. Certification adds administrative cost per shipment through Transaction Certificates. Certified trims, threads and labels are a separate supply chain of their own, and forgetting them late is what delays certified orders. Against that, certified programmes tend to run with fewer quality surprises, because the mills that hold these certificates are usually the better-run mills.

• Higher fabric price and higher fabric minimums for certified material
• Transaction Certificate administration per shipment
• Certified trims, threads and labels, sourced as their own chain
• Testing where your buyer requires a restricted substances report as well
• Lower risk of rework, because certified mills are generally better run

Your first certified order, in order

The sequence matters more here than anywhere else in production, because most of these decisions cannot be taken retrospectively.

• Write the exact sentence you want on the label, then pick the standard that proves it
• Check the threshold: 95% organic fibre for a GOTS “organic” label, 70% for “made with organic”
• Ask us for the factory and mill scope certificates, and verify the numbers yourself
• Confirm certified fabric availability and minimums before you finalise the range
• Book certified trims, threads and labels at the same time as the fabric
• Approve a sealed sample made from the certified fabric, not a substitute
• Request the Transaction Certificate when the goods ship, and file it with the invoice once the certification body issues it
• Keep the evidence for as long as the claim is live on your product page
