Cut-and-sew workwear · 300 pcs per style · OEM & private label

Custom Workwear Manufacturer for Wholesale & Private-Label Work Uniforms

SDF Clothing is a custom workwear manufacturer producing cut-and-sew work uniforms for brands, uniform distributors and wholesale buyers in the US, UK, Canada, Australia and Japan. Our minimum is 300 pieces per style, and sizes and colours are split inside that quantity. We work from your tech pack, reference sample or specification, and we control the order from fabric approval through pattern, cutting, sewing, branding, inspection and export packing.

Shirts, trousers, coveralls, cargo pants, bib pants, aprons and industrial jackets, with OEM and private-label options. For EN ISO 20471 hi-vis see our hi-vis workwear page; for scrubs and clinical wear see medical uniforms. Manufactured in Bangladesh and supplied to international B2B buyers.

This is a factory-direct, cut-and-sew program. Every style starts with a pattern, a fabric approval and a marker, so the production model suits buyers who order a defined style in volume and reorder it, not buyers who need a handful of decorated blanks. If your order is a custom style of 300 pieces or more, this is the right page; if it is smaller, we will tell you honestly rather than quote something that does not fit.

The 300-piece minimum applies per style, not per size and not per colour. You choose the size ratio and colour split inside the 300, and we confirm both before cutting. A style is one design with one pattern and one construction specification.

Example: one work-trouser style, 300 pieces

Illustrative split only — your size curve and colours are set in your own order.

Workwear fabric is specified, not guessed. Our range runs roughly 180–300 GSM across poly-cotton, 100% cotton, ripstop, canvas and FR-treated cloth, and the exact fibre composition, weight, weave and finish are written into the approved specification before bulk fabric is booked.

Why GSM alone does not define workwear quality

GSM (grams per square metre) tells you how heavy a fabric is, not how well it will wear. Two fabrics at the same GSM can behave very differently depending on fibre composition, yarn count, weave and finishing. A tightly woven twill and a loosely constructed fabric of equal weight will not resist abrasion, seam slippage or shrinkage in the same way. We therefore confirm weight against the approved specification and judge it together with construction, not on its own. If you are comparing weights across suppliers or converting between ounces and grams, use the GSM converter and read our fabric GSM guide.

Yarn count, weave and construction

Yarn count (for example Ne 20s or 30s) sets yarn fineness and, with thread density, the weight and hand-feel of the cloth. Twill and drill give the diagonal structure that suits trousers, shirts and coveralls. Ripstop adds reinforcement threads in a grid to slow tear propagation. Canvas gives heavier body for jackets, bibs and aprons. Piqué and rib are knit constructions used for polos, cuffs and collars. Fabric width matters too: usable width is fed into marker planning because it directly controls how much fabric each garment consumes.

Shrinkage, colourfastness and shade control

Workwear is laundered often, so dimensional stability and colour retention are specified up front. Shrinkage allowances are considered before the pattern is approved, and colourfastness to washing and rubbing can be written into fabric approval where the end use calls for it. Bulk production is run from an approved fabric lot with shade information, and mixed lots are kept out of the same production order. Fabric is inspected before cutting for visible defects, shade variation and usable width. Test shrinkage on your own fabric with the shrinkage calculator.

Production begins from the approved tech pack, specification or reference garment. Each size is controlled against the approved measurement chart, and patterns are developed with seam allowances built in according to the construction. Patterns are then graded across your size range before any fabric is cut.

Cutting is not simply placing patterns on fabric. Marker efficiency, grain direction, spreading tension, cutting tolerance and bundle identification all affect how consistent the finished workwear is from the first piece to the three-hundredth. Marker planning positions pattern pieces to control fabric consumption without compromising grain, because off-grain panels twist after washing. Fabric is spread with controlled tension in plies chosen for the fabric's behaviour, and cut components are checked against tolerance before they go to sewing. Notches align sleeves, panels and pockets, and critical construction points can be marked so pocket and trim placement repeats exactly across sizes.

A work garment is broken into controlled sewing operations rather than treated as one generic assembly step. For each construction point we confirm the stitch class, stitches per inch (SPI), needle, thread and any reinforcement in the specification, and the operator and line leader work to that sheet.

Stitch types and when each is used

Stitch types follow the ISO 4915 classes. Lockstitch (class 301) gives a controlled, durable straight seam for topstitching, zip insertion and pocket attachment. Chainstitch (401) is flexible and efficient for long seams. Three-thread overlock (504) controls raw edges, and the five-thread safety stitch (516) combines a chainstitch with an overlock for strong, edge-secured main seams. Coverstitch is used on hems. Flat-felled seams enclose the raw edges for high-wear areas, and double- or triple-needle construction is specified only where the seam justifies it, not applied by default.

SPI, needle and thread

SPI is set according to seam type, fabric and required strength: too few stitches weakens the seam, too many perforates the fabric and causes puckering. Needle size and point are matched to fabric weight and thread so that heavy twill and canvas penetrate cleanly while lighter fabrics are not damaged. Thread size is chosen for the fabric and seam, and thread tension and feed balance are controlled to avoid loose loops, seam distortion and puckering. Seam strength can be assessed on critical seams where the buyer requires it. Our SPI guide explains how to read these numbers on a tech pack.

Reinforcement at stress points

Pocket corners, belt loops, tool loops, the crotch junction and zip bases carry the highest load. These points are reinforced with bartacks, rivets or additional rows of stitching as the specification requires, and seam starts and ends are backtacked so stitching does not run back. For cargo and trade trousers see our cargo pants manufacturer page.

The branding method is chosen by fabric, artwork and wash requirement. Embroidery is digitised from your artwork rather than simply scaled from a graphic file, with stitch density, underlay and backing matched to the fabric so the logo stays flat. Printed garments are cured according to the print system and inspected before packing, and every method is approved on the actual fabric before bulk.

Private-label packages include your woven main label, printed care and size labels, hang tags, polybags and master-carton marking. See private label manufacturing.

Trims fail before fabric does, so each one is named in the specification. Zipper type, length and finish are confirmed with the slider; pocketing is selected separately where pocket durability differs from the shell fabric; and fusing parameters are controlled for consistent adhesion without distorting the garment.

Safety standards are certified at garment level by an accredited third-party laboratory, not by the factory. We build to the standard you name, source suitable certified fabric, tape and trims, validate placement and construction on the pre-production sample, and support testing. Confirm the standard and class for your market before design begins.

Factory-level certifications such as GOTS, OEKO-TEX, ISO 9001 and BSCI are listed on our certifications page.

Bulk production starts only after the approved pre-production sample and specification are confirmed. The sealed sample then becomes the physical reference for workmanship and appearance, and inspection findings are documented against the approved specification.

AQL and defect classification

Final inspection is run to an AQL (Acceptable Quality Limit) sampling plan. The AQL level and the definitions of critical, major and minor defects are agreed as part of your inspection specification before production starts, so there is no argument about what counts as a defect after the goods are made. Needle-control and metal-detection procedures can be applied where your compliance requirements call for them.

Work out sample sizes with the AQL calculator and read AQL inspection explained.

Garments are packed to your approved packing and carton specification: polybag, ratio or solid size/colour packing, and carton marks that identify PO, style, colour, size range and carton number. Packed quantities are reconciled against the final packing list before dispatch, and carton audits verify style, colour, size assortment and quantity before shipment.

We support the documentation your import process needs but we do not quote a duty percentage in advance. Duty depends on the HS classification of the actual garment, the origin and the destination's trade rules. Check a classification with the HS code tool and confirm the current rate with your customs broker.

One program, adapted to the destination: labelling, packing and documentation change by market, while the production specification stays the same.

Transit times, freight and Incoterm are confirmed per shipment at quotation. Estimate your own schedule with the lead time calculator.

Every new style carries fixed setup work before the first garment is sewn: pattern development and grading, marker setup, fabric booking at the mill's minimum, trim sourcing, sewing-line set-up and operator training, embroidery or print set-up, inspection and packing. Spread across fewer pieces, that setup either inflates the unit price or forces shortcuts. Three hundred pieces per style is the point where a cut-and-sew line can run a style properly and price it fairly, and it is far below the volumes many certified-workwear factories ask for. It also lets you test a style, then reorder it with the same pattern, specification and approved sample.
