The certificate covers the mill’s fabric, the test data comes from an unwashed sample, and nothing ties the garment to the lot that arrived. An audit finds all three in minutes.
We build to that standard with aramid thread and FR-rated trims, then test the finished garment per lot. Every shipment carries a checkable file number, a lot report tied to the roll codes, and a build you can reorder unchanged.
Pick the hazard, the standard follows, the build follows the standard.
Flame retardant and flame resistant describe the same garment under two trade names. Fire resistant is the loose third label.
Fireproof describes nothing — no woven shell survives unlimited heat.
Arc rating is tested separately. A CAT 2 build is a different garment, not a heavier one.
ATPV marks a 50% chance of second-degree burn; ELIM marks the point below it. Both are measured on the finished garment.
No standard mandates a weight. It sets a thermal floor and leaves the route open — two compliant coveralls can weigh 6oz and 12oz.
Hot plants sit at the light end, radiant heat at the heavy end. Below roughly 4.5oz, weight buys heat relief at the cost of thermal protection.
Four builds cover nearly all FR programs quoted here. Same pattern block, same trim spec — different hazard.
The default build for maintenance, field crews and heavy-industry programs. Two-way front under a storm flap, reinforced knees, room for a full uniform underneath.
FR coverall bibs for crews layering over a base layer, where a full sleeve is a heat or snag liability.
Underarm gussets, back vents and a 6–7oz shell for hot plants and enclosed structures.
Two pattern blocks. Women’s fr coveralls use their own block, graded separately; fr coveralls for men run through the same matrix.
Two routes to the same test result, with very different behaviour over the life of the garment.
Protection is a property of the polymer rather than a finish. Nomex is one aramid brand inside this family, so nomex fr coveralls and aramid coveralls are the same construction.
Softer and cheaper to buy, but the finish is what degrades. Proban and Pyrovatex are the two routes used on treated fr cotton coveralls.
Both routes pass the same flame test. They do not hold the same measurement after 50 industrial washes.
Ask for the wash limit → Laundering rules →Measured on the oil and gas program further down this page. Shrink is where fit goes, and fit is where coverage goes.
Most FR failures brought in for diagnosis are trim failures. Thread, hardware and tape bought on price after the shell was specified.
Aramid, continuous filament, 10–12 stitches per inch at every load-bearing seam
Standard polyester thread melts before the shell does
The seam is the first place an inspector looks, and a melting thread voids the rating there even when the fabric tests clean.
Non-sparking brass with an insulating layer beneath, or FR-rated plastic
Exposed nickel snaps and standard nylon zip tape
Metal snaps conduct heat through the shell; a zip tape can melt even when the teeth are right. A storm flap short of the zip is a reject.
FR-rated retroreflective tape, FR-rated interlining and fusible
Standard tape bonded onto an FR shell
The tape and interlining become part of the garment. A non-FR tape on an FR shell fails as a combined system even when the shell alone passes.
A certificate on a website says nothing about the garments in the storeroom. A lot report does — when it survives the five checks below.
Agreed before cutting, not after. Inline inspection at AQL 2.5, FR components tightened to zero; pre-shipment at AQL 4.0 on a random draw from finished cartons, with seam strength, trims, label and lot code in the same agreement.
Buyer inspectors and third-party agencies are welcome, and random pieces can go out for independent lab testing. An old report is never reissued under a new date, and a sample-room report is never reused for bulk.
A permanent label carries the certifier’s mark and a file number. Ask for a photograph of it on a garment out of the lot, rather than a certificate with no garment attached.
The directory is public. Search the file number, the company name or the Category Control Number, and confirm the entry is active rather than archived.
Fabric scope and finished-garment scope are two different claims. Confirm the entry names the model and the fibre blend matches the order.
Roll code to cut ticket to garment. If it cannot be matched to the rolls cut for your order, it describes somebody else’s shipment.
A flame result without the laundering behind it says nothing about year three. Ask which method ran and how many cycles preceded the test.
Three separate standards, not one — NFPA 2112, ASTM F1506 or IEC 61482, EN ISO 11612 and EN ISO 11611. Run these five checks against every supplier on the shortlist, this one included; a file number that fails to resolve in the public directory is ours to fix.
Two things decide an FR program: how long the run takes, and what it costs once it clears customs.
Hazard, standard, weight band and quantity fixed before quoting. The clock starts at deposit and approved sample, not the enquiry.
Cut in the production fabric and signed off on a body rather than on a drawing.
Standard run. Mill documents checked and the lot held before the rolls reach cutting; rush is quoted per order.
Checked on the line and on finished cartons at AQL 2.5 / 4.0, reported against the lot code.
The tariff heading follows the fibre, so the same coverall can land in a different bracket by blend alone. The six digits below are the international layer — HTSUS and TARIC extend them by two to four more, and the rate is set there.
| Fibre | Men's / Boys' | Women's / Girls' |
|---|---|---|
| Cotton | 6211.32 | 6211.42 |
| Man-made fibres aramid · modacrylic · nylon blends | 6211.33 | 6211.43 |
| Coated or laminated shell | 6210 the heading moves, not just the rate | |
Freight, duty and VAT arrive as separate charges.
Nothing arrives after the invoice.
The code is declared on the invoice; the rate itself is your broker’s call against the exact fibre content, not the word “workwear”. Classifications sit in the Harmonized Tariff Schedule, EU rates in TARIC.
What each buyer held before the rebuild, and what turned out true once the garment, rather than the datasheet, became the unit of proof.
Four regional suppliers, four fabric specs, and no batch record of which garment protected which worker. An internal audit had already found 30% of coveralls carrying illegible FR labels after 25 washes.
Cost per wear fell 41% and premature replacements fell 68%; the whole range now carries certification an auditor can check, and reorder points run off burn rate rather than a calendar.
Certificates that described the fabric rather than the coverall, test data drawn on unwashed samples, and a supplier reading NFPA 2112 as an arc rating. Quotes stopped at FOB with no HS code behind them, and trial and bulk shipments shared one schedule.
Both audits cleared on the first pass, the delivery schedule held across the project, and the shift to inherent aramid traded a higher unit price for a replacement cycle the buyer could finally forecast.
Both are possible, but they are not equivalent. Home washing is acceptable for garments whose FR performance is inherent to the fibre, provided the care label is followed and no fabric softener or chlorine bleach is used.
Treated FR cotton is the one that degrades: the chemical finish is what burns out, and domestic machines with hard water and heavy detergent accelerate it. Where crews launder at home, specify inherent FR or budget for replacement sooner.
No. The defensible terms are flame resistant, flame retardant and arc rated, each tied to a test standard. A supplier advertising a fireproof coverall should be asked which standard the claim is measured against.
Yes. Send a worn-in reference garment plus a size chart and grading rules.
The pattern is reverse-engineered, graded from XS to 6XL with separate men’s and women’s blocks, and a fit sample is cut in the production fabric before bulk starts. The measurement method is in the coverall size chart.
100 pieces per style, unchanged by category. A program with four builds is four minimums of 100, cut on separate runs and consolidated into one shipment. Sizes can be mixed freely inside a style — the minimum is per style, not per size.
Yes — that is usually why a program moves to a single source. Documents can be issued per shipment so each site gets a compliance file, and the approved sample is archived against the pattern for reorders.
30% deposit to start production and 70% before shipment. After three completed orders, net-30 is open for discussion. T/T, L/C and trade assurance are all accepted, and all payments run against a proforma invoice carrying the full company and banking details.
It does not ship. A lot that misses the agreed acceptance criteria is held, and the failure is traced to the component or the operation that caused it before anything is recut.
Where the failure is on this side, rework or replacement is at no charge. Where it comes from a specification change made after cutting started, the rework is quoted before it begins.
The buyer owns the tech pack, the artwork and any measurement set sent in — those leave on request. The pattern block drafted for the program is never cut for another buyer. Losing a reorder is preferable to selling that block to a competitor.
Embroidery in low-flex areas with FR-rated thread is routine and is written into the trim specification before cutting.
What does damage protection is a standard polyester patch, a heat-transfer film, or dense decoration over a flex or flame-exposed area — those melt, or block the shell from self-extinguishing.
Thread, backing and a placement map are fixed in the tech pack, so a reorder decorates the same coordinates. Placement and stitch counts sit under embroidery.
Retire on evidence, not on a calendar.
A garment comes out of service when the label is no longer legible, the shell is torn or holed, it has absorbed a flammable substance, or industrial laundering has reached the cycle limit named on the lot report.
Those are the four conditions an auditor checks; a fixed replacement date substitutes for none of them.
