Custom Coveralls in Bulk: Fabric, FR, MOQ & Cost
Custom coveralls in bulk start at a 100 piece minimum per design, cost roughly $12 to $45 per unit factory-direct depending on fabric, flame-resistant rating, and quantity, and ship in about 3 to 5 weeks of production after sample approval. Standard duty coveralls use 220 to 320 GSM cotton drill or 65/35 poly-cotton, while FR jobs need an arc-rated or flash-fire fabric certified to NFPA 70E or NFPA 2112 with the arc rating in cal/cm2 printed on the ASTM F1506 label.
Industrial workwear is one of the steadier categories US buyers order in 2026, with the global market near $20 billion this year and North America leading flame-resistant demand on the back of OSHA and NFPA enforcement across oil and gas, utilities, and construction. Coveralls are the workhorse of that category. Buying them custom in bulk lets a company put its name on one consistent, compliant garment across a whole crew at a controlled per-unit cost instead of paying retail per piece. This guide covers the coverall types and fabric weights, when you actually need FR, how the garment should be built to survive a work year, how to decorate it without voiding a rating, and the real MOQ, 2026 cost, and lead time to a boxed US delivery.
What is a coverall, and why buy custom in bulk?
A coverall is a one-piece garment that covers the torso, arms, and legs over the wearer's own clothes, closed by a full-length front zip or snap placket. It is the standard outer layer for mechanics, painters, oil and gas hands, electricians, food processing, and industrial maintenance because it protects everything at once and comes off fast. Coveralls differ from bib overalls (no sleeves, no torso cover) and from a two-piece shirt-and-pant set, which trades full coverage for easier sizing and laundry.
Buyers order coveralls custom in bulk for three jobs: outfitting a full crew to one approved spec, carrying a company logo so the workforce reads as a team on site, and holding cost across a rolling headcount. Ordering to a single production spec means every unit matches on all 100 or 1,000 pieces, and next quarter's reorder is the same garment rather than a near-miss from a different supplier. A coverall program usually sits alongside the rest of a company's corporate uniform program, and the work pants worn under or instead of coveralls come from the same factory line, our trousers manufacturing line builds the matching work trousers to the same fabric and color standard.
Which coverall type and fabric weight do your crews need?
The fabric weight decides how the coverall wears and how long it lasts. Too light and it abrades through in a season; too heavy and crews overheat and stop wearing it. Match the weight to the work, and put the exact GSM and blend in the tech pack so every quote is measured against the same build.
| Fabric | Weight | Best for | Trade-off |
|---|---|---|---|
| Poly-cotton 65/35 | 190 to 245 GSM | General maintenance, light assembly, warm climates | Best breathability and shrink control, lower abrasion life than heavy cotton |
| Cotton drill | 220 to 260 GSM | Garages, workshops, indoor mechanics | Comfortable, soft, dyes well; needs pre-shrink and takes longer to dry |
| Heavy cotton drill | 280 to 320 GSM | Welding-adjacent, heavy fabrication, high-abrasion trades | Longest wear and best spark resistance in cotton; heavier on the shoulders |
| Ripstop poly-cotton | 200 to 240 GSM | Field service, oil and gas, tear-prone environments | Grid weave stops tears spreading; slightly stiffer hand |
| FR treated or inherent | 240 to 350 GSM | Arc flash, flash fire, hot work | Certified protection; higher cost and set fabric list, see the FR section |
A practical starting point: indoor mechanics and workshops take 220 to 260 GSM cotton drill for comfort; construction, utilities, and outdoor field crews take 245 GSM poly-cotton or ripstop for durability and quicker drying; heavy fabrication takes 300 GSM and up cotton. Spec the coverall in the format the crew needs too, standard full-zip for most trades, stud-front for quick removal near heat, and a lighter mesh-vented back panel for hot-climate work.
Do your crews need FR or arc-rated coveralls?
If a worker can be exposed to flash fire or an electric arc, the coverall is PPE and has to be certified, not just labeled flame resistant. This is the single most expensive spec decision on the order, so get it right before sampling. There are two US standards, and they answer different hazards.
| Standard | Hazard it covers | What the label must show | Who needs it |
|---|---|---|---|
| NFPA 2112 | Flash fire (short, intense flame exposure) | Certification to NFPA 2112, fabric passes the ASTM F1930 manikin test | Oil and gas, petrochemical, drilling |
| NFPA 70E | Electric arc flash | Arc rating (ATPV or EBT) in cal/cm2 on an ASTM F1506 label, matched to the site PPE category | Electrical utilities, electricians, plant maintenance |
| Both (dual certified) | Arc and flash fire | Carries the NFPA 2112 mark and an ASTM F1506 arc rating | Crews facing both hazards, common in energy |
Arc rating is expressed in calories per square centimeter (cal/cm2). Common coverall arc ratings run about 8.6, 12, and higher, and the label carries whichever value is lower between ATPV and EBT. Site rules driven by NFPA 70E sort tasks into PPE categories, and the garment's arc rating must meet or beat the category's minimum. A plain garment that only self-extinguishes does not satisfy OSHA where an arc-flash or flash-fire boundary applies; OSHA enforces this through 29 CFR 1910.269 for electrical work and the General Duty Clause elsewhere. If you are not certain a crew faces these hazards, they likely need standard duty coveralls from the fabric table above, plus a hi-vis layer. For high-visibility requirements see our guide to custom hi-vis safety workwear, which covers the ANSI/ISEA 107 classes.
How should a bulk coverall be built to last?
Fabric gets the attention, but construction decides whether a coverall survives a work year or splits at the crotch in month two. These are the build points to name in the spec sheet, because a factory will quote to whatever you leave unstated.
- Seams: double-needle felled seams on the main body and inseam, bartacks at every stress point (pocket corners, fly, crotch junction, sleeve set). Single-needle overlock alone will fail early on a work garment.
- Closure: a heavy YKK-grade brass or nylon two-way zip lets the wearer open the leg for boots and vent heat. Add a storm flap with snaps over the zip for FR and outdoor builds.
- Reinforcement: extra layers or gusseting at the knees, elbows, and seat for kneeling trades; a bi-swing or action back at the shoulders so the wearer can reach without the garment binding.
- Pockets: spec the pocket set to the trade, chest, hip, rule pocket, and back patch, with bartacked openings. Concealed metal (no exposed rivets) for FR and food-safe builds.
- Thread and trim: match thread to the fabric, and for FR garments every component, thread, zipper tape, and label, must be FR-compatible or the certification is void.
Get one sealed sample made to this spec and wash-test it before the bulk run. A 5 to 10 wash cycle test surfaces shrinkage, color loss, and seam slippage while it is still cheap to fix. Coveralls sit in the same durability bracket as heavy work trousers, and buyers often source both together from our US trousers supply line to keep the whole outfit on one fabric and color standard.
How do you add a logo without voiding the garment?
Decoration on a coverall is not the same as on a t-shirt, because the garment is often PPE and always high-wear. The method has to survive industrial laundry and, on FR garments, must not break the rating.
| Method | Best for | Notes |
|---|---|---|
| Embroidery | Chest logo, name, trade | Most durable through industrial wash; on FR garments use FR thread and backing, or a sewn-on FR name tape |
| Woven or embroidered patch | Company and crew ID, swappable names | Heat-sealed or sewn; sewn is required on FR |
| Screen print | Large back logo on standard duty coveralls | Low cost at volume; not for FR unless using a certified FR print system |
| Reflective heat transfer | Visibility striping and back text | Adds low-light visibility; keep off certified FR unless the transfer is FR-rated |
The compliance rule for FR is simple: any decoration and every component must be FR-compatible, or it can void the certification you paid for. Keep the design to original, non-licensed artwork, your own company name, logo, and crew identifiers, not licensed league, team, or third-party marks. Embroidery is the default for coverall branding because it survives the wash cycle; the same embroidery line runs our embroidered work trousers, so a matched program keeps stitch count and placement identical across garments.
What is the MOQ, cost, and lead time in 2026?
Factory-direct pricing depends on fabric, whether the garment is FR certified, decoration, and quantity. These are realistic 2026 bands for a custom coverall program made to spec and shipped to the US, before duty and freight, which vary by lane and current tariff.
| Build | Typical MOQ per design | Factory-direct unit cost | Production lead time |
|---|---|---|---|
| Standard poly-cotton or cotton drill | 100 pieces | $12 to $22 | 3 to 4 weeks after sample |
| Heavy cotton or ripstop, reinforced | 100 pieces | $18 to $30 | 3 to 5 weeks after sample |
| FR treated, certified | 150 to 300 pieces | $28 to $45 | 4 to 6 weeks after sample |
| FR inherent, dual certified | 300 pieces | $45 and up | 5 to 7 weeks after sample |
MOQ is per design and colorway, so a single size run across one spec hits the minimum fastest; splitting one order across three fabrics means meeting the minimum three times. FR fabric carries a higher minimum because the certified rolls are ordered in set widths. Unit cost drops with volume: the move from 100 to 500 pieces on a standard coverall typically takes 15 to 25 percent off the per-unit price. Add about 1 week for a physical sample and approval before the production clock starts. For a fuller breakdown of how minimums, price breaks, and turnaround interact, see MOQ, pricing, and lead times explained. Coveralls also pair naturally with a healthcare or facility program; buyers running mixed sites often add custom scrubs in bulk on the same order.

Frequently asked questions
What is the minimum order for custom coveralls?
The standard minimum is 100 pieces per design and colorway for non-FR coveralls. FR certified builds carry a higher minimum, usually 150 to 300 pieces, because the certified fabric is ordered in set roll widths. Splitting one order across several fabrics means meeting the minimum for each.
How much do custom coveralls cost in bulk in 2026?
Factory-direct unit cost runs about $12 to $22 for standard poly-cotton or cotton drill, $18 to $30 for heavy or reinforced builds, and $28 to $45 or more for certified FR coveralls, before duty and freight. Moving from 100 to 500 pieces typically takes 15 to 25 percent off the per-unit price.
Do my coveralls need to be flame resistant?
Only if workers can be exposed to flash fire or electric arc. Flash-fire work needs NFPA 2112 certified fabric; arc-flash work needs an ASTM F1506 arc rating in cal/cm2 matched to the site PPE category under NFPA 70E. If neither hazard applies, standard duty coveralls in cotton drill or poly-cotton are the right call.
What fabric weight is best for work coveralls?
For indoor mechanics and workshops, 220 to 260 GSM cotton drill balances comfort and wear. For construction and outdoor field crews, 245 GSM poly-cotton or ripstop dries faster and resists tears. Heavy fabrication takes 280 to 320 GSM cotton for maximum abrasion and spark resistance.
How long do custom coveralls take to produce?
Standard coveralls run about 3 to 4 weeks of production after sample approval, reinforced heavy builds 3 to 5 weeks, and certified FR coveralls 4 to 7 weeks depending on fabric. Add roughly 1 week for a physical sample and sign-off before the production clock starts, plus transit to the US.
