Organic Cotton Clothing Manufacturer

Collective Studio, a GOTS-certified (RSC 9687) knitwear factory in Narayanganj, Bangladesh, makes custom organic cotton t-shirts for small brands from 150 pieces per style and colour, cut and sewn to your pattern under your label. You can choose organic single jersey or organic rib at that minimum. The yarn is certified and is knitted and dyed at certified partner mills, and the cutting and sewing happen on our own certified floor, so the chain of custody runs unbroken to the finished tee and it can carry the claim. Your brand is the only brand name on the garment. If you use the GOTS label, it also carries the certification body and certification number, as the standard requires, and we supply those details for your order. Tell us the fit, neckline and fabric weight you want, and we will say which organic fabric suits it. Fits, necklines and trims are covered on our private label t-shirt page.

Our minimum for organic cotton clothing is 150 pieces per style and per colour, the same as for conventional cotton, with sizes flexible within that. Every colour is its own dye lot at a certified dyehouse using GOTS-approved chemistry, and that dyehouse has fewer stock shades to draw from than a conventional mill. One colour at 450 pieces fills a single lot, while three colours at 150 each means three lots and three bookings, and the unit price reflects that. Trims are the second effect: thread, labels and elastic on a GOTS-labelled garment must meet the standard's input rules and carry minimums of their own, so a small order split across many colours can end up buying more thread and labels than it uses. Our advice is to launch organic with one or two styles you plan to keep, in a small number of colours, and widen later. Test combinations on the MOQ calculator.

Yes: Collective Studio is GOTS certified under certificate RSC 9687, scope certificate available on request, and your organic garments are cut and sewn on our own certified floor in Narayanganj. The spinning, knitting and dyeing partners upstream each hold their own scope certificate, because GOTS certifies a chain of facilities rather than a single building. That matters for what you can claim: a finished garment only counts as certified if every stage that processed it is certified. When you ask, we send the scope certificate itself, not a logo image. Check two things on it: that the facility named is the site that will make your garments, and that the product categories cover the garments you are ordering. If a supplier will not show a numbered certificate naming its own facility, treat that as your answer. For the wider checks, see how to check any GOTS claim.

Yes, organic cotton costs more, and it is worth it when your positioning depends on a claim you can document. Certified yarn costs more per kilo than conventional cotton of the same construction, and because fabric is bought by weight, a heavyweight organic hoodie carries more of that premium per piece than a lightweight tee. Adding elastane changes the fabric rate and decides whether the garment can carry the claim at all. If you need a Transaction Certificate for a stockist or an audit, the certification body issues it per order with its own fee, so it goes in the quote. The premium pays back in three ways: a clearer story, a defensible reason to charge more, and access to stockists who want certification before listing anything as organic. If nobody is asking for documentation and your budget is tight, conventional cotton with no environmental claim is the honest choice. Rough out your costing with the pricing calculator.

Most of our knitwear can be made in certified organic cotton: tees, polos, hoodies, sweatshirts, joggers, loungewear, kidswear and intimates. What decides it is fibre composition, not garment type. A GOTS label grade is set on the fibre content of the garment's fabric, not counting trims such as thread, labels and elastic, so a fleece hoodie or a kidswear piece qualifies if its fabric does. Anything knitted from polyester or nylon and containing no organic fibre cannot carry the claim, whatever the style. Those trims are assessed separately and must still meet GOTS limits for chemical residues; a STANDARD 100 certificate from OEKO-TEX is accepted as proof, at Class 2 for most goods and Class 1 for baby textiles. Plan for that on intimates in particular, where elastic is part of the construction. Send us the range you are planning and we will flag which pieces can carry the claim and which cannot, before you commit to packaging.

Only if every fibre in it is certified organic cotton: a 95% organic cotton, 5% elastane piece cannot say 100%, and any GOTS reference on the label has to describe the product, not the cotton. GOTS has two label grades. "Organic" requires 95% or more certified organic fibre, so that 95/5 blend still qualifies for it, while "made with x% organic materials" requires 70% or more. GOTS guidance published in September 2026 pre-approves "This product is GOTS-certified." and lists "GOTS cotton" and "GOTS-certified organic cotton" as wording not to use. On a product, a GOTS reference also needs complete labelling: logo, label grade, certification body and certification number, a rule in force since 1 August 2026. We supply the certification details your label needs for your order. With new EU rules on green claims now applying, we confirm your permitted wording in writing before labels print. The grades are explained in how GOTS label grades work.

No: Collective Studio does not sell blank organic tees from stock; we manufacture your design to your pattern and measurements, with your label in it. If you need a handful of blanks quickly, a supplier of printable blanks will serve you better, and we would tell you so. There is a certification reason too: for a finished tee to be GOTS-labelled, every stage that processed it has to be certified, cutting and sewing included. GOTS's claims guidance states that certified fabric sewn in an uncertified facility breaks the chain of custody, and that "made with GOTS-certified fabric" is not an allowed claim on the finished product. Buying blanks means relying on that chain for someone else's garment; making the tee on our certified floor keeps it with one company you can question directly. Our route is made to order from the same 150-piece minimum per style and colour. The wholesale clothing manufacturer page compares blanks with custom manufacturing.

A Scope Certificate proves a company is certified; a Transaction Certificate proves that one shipment was. A Scope Certificate names the certified entity, its certification body and the product categories in scope; ours is RSC 9687, and we send it on request. It shows we can produce GOTS goods, but a factory holding one can still ship a run that was never made as certified. That is why retailers and auditors ask for the Transaction Certificate: it names the products, quantities and buyer for your specific shipment. It is quoted per order, and when you ask for it matters. A Transaction Certificate is drawn up from the production records of the order it covers, so it is far easier to issue while your order is running than after the goods have shipped. If you sell to stockists or expect an audit, say so when you place the order. Ask for both at the start, not during a stockist's compliance check.

Yes: we arrange a GOTS Transaction Certificate on request for an order of 150 pieces per style and colour, as for a larger run. The fee is set by the certification body for each order; we quote it for your order and add it to your costing. Because the fee is per order rather than per piece, it weighs more on each garment in a 150-piece run than in a large one, worth knowing before you set your wholesale price. If you are launching several styles, placing them in one order means one certificate to arrange rather than one for each separate order. The certificate lists what was shipped, how much and to whom, which makes it the document retailers, marketplaces and auditors want before they accept an organic claim on your goods. Decide at order stage: tell us who needs it, and we apply for it as soon as your DDP shipment leaves. Asking after delivery is the hard way.

Yes: under GOTS 7.0 an organic cotton garment can contain up to 10% virgin synthetics such as elastane, or up to 20% recycled synthetics such as recycled polyester, with no extra room for leggings or sportswear. Virgin polyester, acrylic and conventional cotton are not allowed in any amount. A worked example: a 90% organic cotton, 10% elastane jersey sits exactly at the virgin-synthetic cap and falls below the 95% needed for the "organic" grade, so it would carry the "made with 90% organic materials" wording. From 1 March 2027, under GOTS 8.1, virgin and recycled versions of the same fibre cannot be mixed in one product, so the elastane in a garment must be either all virgin or all recycled. Claiming the recycled content itself needs GRS or RCS documentation alongside GOTS, and the certificate we hold is GOTS. Decide blend and wording together, before fabric is booked. Stretch pieces are covered on our leggings page.

Choose organic when your brand needs a documented fibre claim and consistent colour; choose recycled when cutting virgin-fibre use matters more than a certificate. Certified organic has full staple length, handles like premium conventional cotton and takes the full colour range, dyed within the certified chain, at a premium over conventional. Recycled cotton is reclaimed fibre with a shorter staple, so it is usually blended to hold strength. Its colour range is narrower because it often keeps the reclaimed fibre's existing colour, and its price varies because sorting and blending add cost. So recycled is the wrong pick if you need the same shade across repeat runs. The claims are documented differently: organic through GOTS, recycled content through GRS or RCS. We hold GOTS only (RSC 9687), not GRS or RCS, so we cannot document a recycled-content claim; if it is central to your range, choose a GRS or RCS-certified producer. Our sustainable clothing page covers the wider fabric choices.

Yes, on paper: each certified stage from ginning to our sewing floor in Narayanganj is documented, and the Transaction Certificate for your order is the link a retailer checks. The farm itself sits outside GOTS. Raw cotton has to be certified organic under an accepted organic standard before it enters the GOTS chain of custody, and GOTS then covers processing from ginning onwards. The organic lot is documented as it moves along that chain. As the buyer, you hold two documents. Our Scope Certificate, RSC 9687, shows the processes and product categories our floor is certified for. The Transaction Certificate covers your shipment specifically, so a retailer can confirm that your particular goods, not just your supplier, came through certified processing. Ask for it when you place the order. If a claim you plan to make depends on farm-level origin, raise it before you order and we will tell you what documentation is available.

Make only claims that are specific, true for the exact product, and backed by a document you can produce. GOTS guidance on claims, published in September 2026 with the EU Empowering Consumers directive in mind, flags five high-risk types: generic words such as "green", "sustainable" or "eco"; future promises with no credible plan behind them, such as all products certified by a set year; absolute words such as "harmless" or "chemical-free"; wording that implies a whole collection is certified when only some garments are; and legal requirements presented as a special benefit, such as meeting REACH. That directive, (EU) 2024/825, applies from 27 September 2026. The GOTS guidance's closed list of pre-approved claims is the safest wording to reuse. Keep the certificate paperwork to hand. Labour claims can be documented too, because GOTS checks working conditions along the chain against core ILO conventions. See our guide to labels, hang tags and packaging.

Organic cotton clothing is made in the same steps as conventional, with the organic lot kept separate and documented at each one. Certified organic cotton is grown by farm groups on annual cycles, so large or unusual quantities are booked at the spinner ahead of the order. Spinning and knitting run at certified partner mills we visit, book and inspect, where the organic lot is processed apart from conventional fibre. A partner dye house then dyes the fabric to your physical lab dip using only GOTS-approved dyes and auxiliaries, which is why some very deep or fluorescent shades need reformulating rather than mixing. The fabric is relaxed and inspected, then cut and sewn on our own certified floor in Narayanganj, with certified and conventional runs kept physically apart. Finally, each run is wash-tested and shade-checked against your approved lab dip, not a Pantone code, so repeat runs match, then shipped DDP with a Transaction Certificate if you requested one.

Yes, in the sense that dyeing and finishing any cotton uses chemistry; what GOTS changes is which chemicals are allowed and whether that is on record. GOTS restricts dyes, auxiliaries and finishes at every processing stage against toxicity and biodegradability criteria, and bans some groups outright, including azo dyes that release carcinogenic amines, chlorine bleach, formaldehyde and heavy metals; PFAS are banned under version 7.0. Every wet-processing unit in the chain, such as the dye house, must also treat its wastewater. For the wearer, that means every dye and finish on the certified fabric came from an assessed, approved list, and the trims had to meet GOTS residue limits: a documented answer, not a promise that it is harmless. OEKO-TEX STANDARD 100 works differently: it tests the finished textile against limit values and has no fibre-content requirement. One caution: some substance limits are already required by EU law under REACH, and GOTS guidance says not to present legal compliance as a GOTS extra.

Organic cotton is not better across the board; it differs from conventional cotton on specific points you can prove, at the farm and in the paperwork. At the farm, it is grown without synthetic pesticides or genetically modified seed. In the finished garment, the fibre behaves like premium conventional cotton, so against a premium conventional tee the difference is not in the hand. The bigger difference for a brand is what you can document. Conventional cotton supports no fibre claim beyond its composition; certified organic can be backed by a certificate covering the processing chain and, for your order, a Transaction Certificate. GOTS guidance treats wording that implies an advantage over non-certified products as a claim that needs robust, verifiable evidence, so describing the certification is safer than calling the product "better". For a price-led range with no environmental claim, conventional remains the right call. Our guide to sustainable fabrics compares the other options.

Yes, organic cotton clothing shrinks in the wash as much as any cotton knit, because organic cotton has the same staple length and spins to the same counts as conventional. Expect around three to five per cent residual shrinkage on a well-finished cotton jersey tee, more in length than in width, after the fabric has been relaxed and compacted before cutting. That finishing takes most of the shrinkage and twist out in advance, and the pattern is given a little extra to cover what remains. Do not rely on a mill's shrinkage figure. We wash-test and measure the garment before and after, and record the result against your spec. Build your size chart from those post-wash figures and set its tolerances around them, so the chart matches the tee after laundering. Grading is covered in how to build a size chart.

Yes. From 150 pieces per style and colour we handle an organic order full package, so you do not have to find certified fabric yourself. Certified yarn is knitted and dyed at certified partner mills we book and inspect, the cloth comes to our GOTS-certified floor in Narayanganj (RSC 9687), and we cut, sew, label, inspect and ship it DDP. That matters because certification follows the goods: if certified fabric passed through an uncertified sewing unit, the chain would break and the finished garment could not carry the claim. For tees, organic single jersey and organic rib are both available at that minimum, and the jersey runs in the same 140–240 GSM range as conventional. The quote lists the fabric, the trims that meet GOTS input rules and, if you need one, the Transaction Certificate fee. Our low-MOQ manufacturing page shows how the 150-piece minimum works across a range.

In the fibre, nearly: both are all cotton, and certified organic cotton has the same staple length and spins, knits and feels like premium conventional cotton. The difference lies in how it was grown and what can be proved. Organic cotton is grown without synthetic pesticides or genetically modified seed, and before it enters the GOTS chain the raw cotton must be certified under an accepted organic standard; each processing stage after that is certified and documented. "100% cotton" tells a shopper the composition and nothing more. "100% organic cotton" claims that every fibre is certified organic, so a garment with even a little elastane cannot use it, and a GOTS reference on the label needs the label grade, the certification body and the certification number. If you plan to make the claim, we confirm your permitted wording in writing before any label is printed.

Sometimes. GOTS lets one Transaction Certificate cover several shipments only if we, our certification body and you agree in advance on the number of shipments or the time period, and the certification body gives written permission. Every shipment must go from the same seller location to the same buyer, a certificate can list no more than 100 shipments, and no more than 90 calendar days may pass from the first shipment to the last. It also cannot stay open beyond the end of our scope certificate. GOTS's own guidance notes that a period closer to 30 days is more realistic in most cases, because goods shipped early are sold before a certification body has verified them. In practice, a launch drop and a quick top-up shipped within that window can share one certificate. A reorder placed months later gets its own. Tell us at order stage which you want, and the plan is agreed before anything ships.

Start with the file. A GOTS Transaction Certificate is issued as a PDF digitally signed by the certification body, with the signature set to allow reading and printing only, so a version that has been edited will no longer show a valid signature. Next, confirm it with the certification body named in its first box. GOTS requires every approved body to offer at least one way to do this: a reply by email within two business days, a lookup page, a web address or QR code printed on the certificate, or the signing certificate itself. The declaration on every certificate points to GOTS’s list of approved certification bodies. Then check the content: the seller’s name and Certification Number should match the scope certificate we sent you, the buyer should be your company, and the purchase order numbers should be yours. Our certifications page explains how to check our scope certificate.
