Step-by-Step: Vanrd's 8-Step QC Workflow

Step 1 – Fabric inspection on inspection machine

We inspect incoming fabric rolls on inspection machines under proper lighting.
QC checks for:
    Stains, oil marks, dirt and dust
    Snags, pulled yarns, holes and thick/thin places
    Colour shading between rolls and within rolls
    Width and weight consistency
Defective sections are marked and recorded so they are not placed into production.

Step 2 – Fabric wash & shrinkage tests

Before bulk cutting we run wash and shrinkage tests on each main fabric.
Typical checks include:
Dimensional change after recommended wash
Handfeel and surface change
Basic colourfastness to washing
Shrinkage data is shared with pattern and marker teams so production patterns are adjusted to keep your final fit on-spec.

Step 3 – Print & embroidery inspection

All printing, embroidery and appliqué passes a dedicated check point:
Artwork size and placement against tech pack
Colour accuracy versus approved strike-offs
Stitch density and coverage on embroidery
No missing stitches, loose threads, ghosting or cracking
Only approved panels move to sewing.

Step 4 – In-line sewing process checks

During sewing, line QC performs in-line inspections by operation:
Seam type and stitch length
SPI and tension balance
Matching of panels, pocket positions and plackets
Correct trims and thread colours
Defective pieces are sent to repair, and recurring issues trigger immediate feedback to line leaders.

Step 5 – End-of-line pre-check

After thread-trimming, ironing and basic finishing, we run an end-of-line pre-check by bundle:
Overall appearance and measurements on sample pieces
Zips, snaps and buttons functioning correctly
Clean garments with no stains or marks
Only bundles that pass this gate move to 100% QC.

Step 6 – 100% QC by dedicated QC team

A dedicated QC group performs 100% piece-by-piece inspection against our checklist and your spec.
They confirm:
Size and measurements within tolerances
Construction and seams without major or critical defects
Branding, labels and hangtags correctly applied
Garments are separated into pass, rework and reject categories, with records kept for every batch.

Step 7 – Pre-packing supervisor audit

Before packing, a line or department supervisor runs an additional audit:
Random re-check of QC-passed pieces
Confirmation that corrections have been implemented
Visual review of finishing quality by size and colour
This second layer helps keep QC standards consistent between shifts and styles.

Step 8 – Packing & carton checks

At packing, our team verifies counts and labels so cartons arrive ready for your DC:
Piece count per polybag and per carton
Size ratios and colour breakdown per your packing list
Barcode, size stickers and carton marks
Only after QC signs off on the packing checklist are cartons sealed and moved to the warehouse.

FAQs — Custom Clothing Manufacturing

  • What garment labels and compliance documents are required for the US or EU market?
    Direct answer

    For the US: fibre content, country of origin, manufacturer identity (an RN number or name) and care instructions, all permanently attached. For the EU: fibre composition under Regulation (EU) 1007/2011, REACH compliance, and since 13 December 2024 an EU-based responsible person under GPSR. In both markets the legal labeler is the brand or importer, not the factory.

    What has to be on the garment

    The two markets overlap on fibre and care, then diverge on identity and on who is accountable. The table is the working checklist we use when a label artwork is submitted for approval.

    RequirementUnited StatesEuropean Union
    Fibre contentTextile Fiber Products Identification Act: generic names and percentagesRegulation (EU) 1007/2011: fibre names and percentages, ±3 percentage points tolerance
    Country of originRequired on imported textile productsOrigin claims must be accurate; "made in" is not mandatory for all goods
    Manufacturer identityRN number, or name and addressName and address of the EU responsible person under GPSR
    Care instructionsCare Labeling Rule, 16 CFR 423: washing, bleaching, drying, ironing, warningsISO 3758 symbols; national rules apply in several member states
    Restricted substancesCPSIA for children's wear; California Prop 65 warning where applicableREACH Annex XVII; GPSR safety and traceability
    Children's safetyTracking label, lead and phthalate limitsEN 14682 drawcord and cord requirements

    What we need from you before we sew a label

    Label content is the brand's legal statement, so we do not draft it. We need the approved artwork, the fibre percentages from the actual fabric and trim composition, the care symbols or text, the RN number or the EU responsible person's details, and the placement and size for each label.

    Fibre percentages have to come from the fabric and trim composition, not from the marketing description. A hoodie described as "cotton" with a polyester rib and poly drawcord still has to declare those fibres.

    What we produce and what we do not

    We sew woven labels, printed care labels, heat-transfer labels and hangtags to the approved artwork, and we can add polybag warnings and carton marks. We check the artwork against the approved fibre list before production, because a label error is a recall risk, not a rework.

    What we cannot do is take legal responsibility for the label content. The brand or importer signs the artwork, and that signature is what the factory produces to.

    Field example

    A US launch of 600 poly-fleece hoodies needed four label elements: 80/20 cotton-poly composition, country of origin, the brand's RN number and four care symbols. The EU sibling order added the GPSR responsible person's name and address, a REACH statement in the technical file, and EN 14682 checks on the drawcord. Artwork was approved in three working days because the fibre list came from the fabric and trim card rather than from the product description.

    Numbers that matter

    • US: four core label elements — fibre, origin, identity (RN), care
    • EU: fibre composition tolerance is ±3 percentage points under Regulation 1007/2011
    • GPSR applies from 13 December 2024 and requires an EU-based responsible person
    • Care symbols follow EN ISO 3758; keep the approved artwork with the order file
  • What is the difference between OEKO-TEX and GOTS certification?
    Direct answer

    They answer different questions. OEKO-TEX STANDARD 100 tests the finished article for harmful substances and is granted per product, with no requirement for organic fibre. GOTS certifies organic fibre content and the environmental and social performance of every processing stage, from fibre to finished garment, and requires chain-of-custody documents at each step.

    Side by side

    A garment can hold OEKO-TEX without a gram of organic cotton, and a GOTS garment also has to meet chemical limits — GOTS includes them, but goes further into fibre, water, energy and labour.

    DimensionOEKO-TEX STANDARD 100GOTS
    What is certifiedThe finished article and its componentsThe organic fibre and the processing chain
    Fibre requirementNone≥70% organic; ≥95% for the "organic" grade
    Chain of custodyNot requiredRequired at every stage, with transaction certificates
    Chemical inputsTested against limit valuesMust come from the approved input list
    Social criteriaNot coveredCovered, audited annually
    Validity12 months, product-specificAnnual audit and certification
    Who holds itThe mill or garment maker for that articleEach certified operator in the chain

    What each one is good for

    OEKO-TEX is the practical answer for a brand that needs to state the garment is safe against a recognised limit list, including for children's wear through product classes I to IV. It is what a European retailer will normally ask for on a fabric and trim file.

    GOTS is the answer for an organic claim. It is also harder to arrange, because every operator in the chain has to be certified and each shipment needs a transaction certificate. A brand cannot decide to "add GOTS" at the packing stage.

    How to verify a certificate, and what we can provide

    OEKO-TEX certificates carry a number that can be checked in the OEKO-TEX buying guide, and the scope has to name the article or component. GOTS certificates can be checked in the public GOTS database, and the transaction certificate is the document that ties a specific shipment to a certified operator.

    Certificates sit with the mill, the printer or the trim supplier that holds them, not with the garment factory. We request the scope that covers your specific fabric, print paste and trims, check that the article description matches, and pass the documents with your order file. We do not describe VANRD as certified for a standard we do not hold.

    If a certificate's scope names a different quality code or a different mill, it does not cover your order, even if it is the same fibre.

    Field example

    A European kidswear brand needed OEKO-TEX product class I for a 320 GSM cotton hoodie. The fabric mill held a certificate covering the quality code, the print paste had a separate certificate from the printer, and the drawcord supplier provided its own. Three documents, one order file. On a later organic programme the same brand moved to GOTS and discovered the fabric mill was not certified, so the order had to be re-sourced before sampling could start.

    Numbers that matter

    • OEKO-TEX product classes I-IV: baby, direct skin, outerwear, decoration
    • GOTS requires ≥70% organic fibre, and ≥95% for the "organic" grade
    • OEKO-TEX certificates are valid for 12 months and name the article
    • GOTS needs a transaction certificate per shipment, not one certificate per year
  • How are defective garments handled after inspection or delivery?
    Direct answer

    Handling depends on when the defect is found. In-line defects are repaired at the station and the cause is logged. Units that fail final inspection are sorted 100% and repaired or replaced before packing. After delivery, a claim is checked against the batch code on the carton and the inspection report, and the outcome is replacement or credit depending on whether the fault is ours.

    Who handles what, and who pays

    The principle is simple: a defect we caused is our cost at any stage; a defect caused after delivery is not. The grey area is wear and wash damage, which is why care labels and wash-test results are kept with the order file.

    After delivery, not a production faultRepair quote or technical adviceBuyer

    What cannot be repaired

    Some faults are terminal: a hole in the body panel, a shade that is out of tolerance across the lot, a label with the wrong fibre content, or a decoration that has cured in the wrong position. These are replaced or credited, not repaired, because a repair would still leave a trace the customer can find.

    Repairs are also capped. If more than a small share of a lot needs repair, the honest answer is to remake the affected size rather than ship a garment that has been through the needle twice.

    Claims and traceability

    Every carton carries a batch code that links to the cutting lot, the sewing line and the fabric roll. A claim with a photo and a batch code can be traced in a day; a claim with a photo alone usually ends in a negotiation.

    The claim window is set in the contract, typically 30 days from delivery, and decorated styles usually ship with 1-3% spare units so a small number of defects does not become a reorder.

    Field example

    A 2,400-piece tee order showed 1.8% wavy neck ribs at final inspection, just under the AQL but visible in a retail fold. We sorted 100%, set aside 43 pieces, replaced them from the 2% spare units packed with the order, and changed the rib attaching tension on the next run. No credit was needed and the delivery date held.

    Numbers that matter

    • 100% sort is triggered when majors exceed the agreed AQL, not when a single defect appears
    • 1-3% spare units are standard for decorated styles
    • Claim window typically 30 days from delivery, stated in the contract
    • Batch code on every carton links to cutting lot, sewing line and fabric roll
  • What happens if the delivered bulk order does not match the approved sample?
    Direct answer

    The lot is frozen and compared point by point against the signed approved sample and spec — not against memory or a photo. We quantify how many pieces are affected, trace the cause to a lot, a cutting batch or a process, and then agree a remedy: rework, remake, or a commercial adjustment. Who pays depends on where the fault sits, and the contract decides that.

    Step by step

    The first 48 hours decide the outcome. If the goods are still in our warehouse the options are wide; once they are in a container or in your warehouse, the practical options narrow to replacement and credit.

    StepActionEvidence produced

    4. TraceFabric lot, cutting batch, sewing line, wash lotBatch records and inspection logs
    5. RemedyRework, remake, credit or rejectionWritten agreement with dates

    What counts as not matching

    A mismatch is a measurable difference from the approved standard: shade beyond the agreed Delta E, measurement outside the tolerance in the spec, a substituted trim or label, decoration in the wrong position or size, or a fabric hand and weight that no longer matches the approved quality code.

    Normal variation inside tolerance is not a mismatch. Garment-dyed styles vary shade across a lot by nature, which is why the tolerance has to be agreed in Delta E before the wash recipe is approved, not after the goods arrive.

    How the remedy is decided

    If the deviation is a production error on our side, rework or remake is at our cost, and we cover the freight consequence of the delay. If it comes from a change the buyer approved late, from buyer-supplied fabric, or from a wash standard the buyer signed off, the cost is shared or carried by the buyer as the contract sets out.

    Either way the remedy is written down with dates before work starts, so there is no second argument about what was agreed.

    Field example

    A 1,000-piece hoodie order arrived with a shade reading Delta E 2.1 against the approved standard, where the agreed tolerance was 1.0. The cause was a different dye lot of the same quality code. 300 pieces were re-dyed to the standard, the remaining 700 were accepted with a credit per piece, and the mill was put on notice that lot changes must be flagged before dyeing.

    Numbers that matter

    • Shade tolerance: Delta E ≤1.0 for solid shades, ≤1.5 for garment-washed styles
    • Assessment within 48 hours of the claim, with 3 pieces per size compared
    • Rework typically takes 7-14 days; remake follows the 25-35 day bulk lead time
    • Keep the approved sample and signed spec — without them a claim becomes an opinion
  • Can I receive an inspection report before my order ships?
    Direct answer

    Yes. Every order produces a pre-shipment report before dispatch, issued as a PDF within 24-48 hours of inspection. It contains the AQL result, the measurement chart against spec, every defect found with photos, the packing and carton data, and a clear pass, conditional pass or fail decision. The order is not released for shipping without it.

    What the report contains

    The report is written so that someone who has never seen the order can understand what was checked and what was found. It references the approved sample and the signed spec version, because a report against an outdated spec is worse than no report.

    SectionContents
    Order dataPO number, style, colourways, size breakdown, quantity

    DefectsCritical, major and minor counts, location, photo per defect type
    PackingPieces per polybag and carton, carton dimensions and weight, shipping marks
    ResultPass, conditional pass or fail, plus the action required

    What the result actually means

    A pass means the lot met the agreed AQL at the agreed level. It does not mean zero defects — a 2.5 AQL accepts a defined number of majors in the sample by design, and the customer should know that number before the order starts.

    A conditional pass means the lot ships only after a named action is completed and evidenced, usually a 100% sort or a specific repair. A fail means the lot is held, and we issue a corrective action with a date.

    Who else can see it

    The report is yours to forward to your customer or to your own inspection company as a starting point. If you book a third-party inspection, our report and theirs sit side by side, and any difference between them is worth investigating before the container is loaded.

    Reports are kept against the order for 12 months, so a claim six months later can be checked against what was actually inspected.

    Field example

    On an 800-piece jacket order the pre-shipment report flagged 12 majors: the zipper pulls were the right design but the wrong finish, gunmetal instead of matte black. The shipment was held for two days while 800 pulls were replaced from stock and 60 pieces were re-pulled. The re-inspection passed, and the report is what made the difference visible before the goods reached the customer's warehouse.

    Numbers that matter

    • Report issued within 24-48 hours of inspection, before dispatch
    • Standard levels: AQL 2.5 major, 4.0 minor, zero critical
    • One inspection day covers up to roughly 3,000 pieces
    • Reports retained against the order for 12 months
  • How can I reduce pilling and fabric wear after washing?
    Direct answer

    Pilling is loose fibres tangling on the surface, so the fix is at the yarn: use combed or combed ring-spun cotton, longer staple, a firmer twist, and brush the inside less. Then confirm it with a Martindale or random-tumble test and accept nothing below grade 3-4. A softer hand-feel and lower pilling pull in opposite directions, so the choice has to be made at sampling.

    Where pilling actually comes from

    Short fibres escape the yarn during abrasion, roll into small balls and stay anchored to the surface. Carded cotton with a high short-fibre content pills faster than combed cotton, and a loosely twisted yarn releases fibres faster than a firm one. Brushing the inside of a fleece improves the hand-feel but also raises more fibre ends.

    Abrasion is not evenly distributed. Underarm, cuffs, the lower back where a bag rubs and the inside of the thigh are where pilling shows first, which is why a wear test on the whole garment hides the problem until the customer finds it.

    Lighter inside brushingLess surface nap to pillLess immediate softness
    Anti-pilling finishMeasurable improvementHand-feel and shade can shift
    Polyester blendBetter abrasion resistanceLoses natural hand and breathability

    How to test it before bulk

    Two methods cover most buyer requirements. Martindale to ISO 12945-2 runs a set number of rubs, usually 2,000, against a standard abradant. The random tumble test, ASTM D3512, puts the sample in a chamber with cork or pumice for 30 minutes. Both produce a grade from 1 to 5, where 5 is no pilling.

    We test on the finished fabric, not greige, because brushing, washing and softening all change the result. For a brushed fleece the inside face is graded separately from the outside, since that is where the customer sees pilling first.

    What to write into the spec

    Put a grade and a method in the spec, not an adjective. "No pilling" cannot be inspected; "Martindale ISO 12945-2, 2,000 rubs, grade 4 minimum, inside face" can be measured, argued and repeated.

    If the brand sells at a premium price point, grade 4 is the realistic target. At volume price points grade 3 is common, and grade 3-4 is a sensible middle.

    Field example

    A 420 GSM brushed fleece hoodie graded 2-3 on the inside face after five home washes, which the brand's returns data had already flagged. We moved the shell to combed ring-spun cotton, reduced the brushing passes and added an enzyme finish. The next lot graded 4 at 2,000 Martindale rubs, with a hand-feel the brand accepted on the first round.

    Numbers that matter

    • Pilling scale 1-5, where 5 is no pilling; grade 3-4 is the usual commercial floor
    • Martindale test to ISO 12945-2 at 2,000 rubs, or random tumble to ASTM D3512 for 30 minutes
    • Combed yarn adds roughly 5-10% to yarn cost and is the single biggest lever
    • Grade the inside face of a fleece separately — that is where pilling appears first
