Care, Testing, Compliance and Sustainability: A Buyer Reference
A good sample becomes a repeatable order only when somebody writes down what was tested and what the buyer is entitled to expect. This hub explains the common tests in plain language, how to read a report, what care labels and HS classification involve, and how to handle recycled-content and sustainability claims without overstating them.
What this hub covers
Testing language is intimidating and mostly unnecessary at the level a small buyer needs. You do not have to run a laboratory. You have to know which question each test answers, what a report does and does not prove, and which two or three tests are proportionate for your order. A pilling grade is meaningless without the method used; a shrinkage figure is meaningless without the wash cycle.
This hub covers wash behaviour and dimensional stability, pilling and abrasion, colourfastness, seam and print durability, and inspection standards. It then moves to care-label content, HS classification at a conceptual level, and recycled-fibre and sustainability claims – an area where vague language is common and expensive. Standards such as ISO, AATCC, ASTM and OEKO-TEX are described as method families or documents to request from a test house or supplier, not as certifications Fexwear holds.
The compliance discussion is deliberately cautious. This page is not legal, customs or tax advice, and it does not tell you what is required in your destination market. It tells you which questions to ask and which documents to request.
Pick the one or two failures most likely for your garment and read those test sections. Skip the rest. Then use the checklist to write the requests into your order.
Wash behaviour and dimensional stability
A dimensional stability test washes a sample under agreed conditions and measures it before and after. The useful output is not a single percentage but the conditions: wash cycle, temperature, drying method, number of cycles and the tolerance you agreed. Cotton-rich knits commonly show their largest change on the first wash; polyester-dominant knits are usually more stable. Treat any quoted band as a starting point for a test request, never as an acceptance criterion copied from a guide.
Measure the assembled garment, not only a flat swatch. Rib cuffs, neckbands, zips, tapes and printed panels shrink at different rates, and their interaction is what a wearer sees: a waved neckline, a twisted side seam, a hem that no longer sits level. Record length, width and any twist or skew, and compare against the tolerance in the tech pack.
| Test element | What to specify | What the report must state |
|---|---|---|
| Wash cycle | Programme, temperature, detergent, load | The cycle used, not just a pass or fail |
| Drying | Line, flat or tumble, and temperature | The drying method used |
| Cycles | One, three or five | Number of cycles before measurement |
| Measure points | Length, width, hem, sleeve, twist | Measured values before and after |
| Tolerance | Agreed plus or minus per point | Whether the result falls inside it |
Two suppliers can quote different shrinkage figures and both be right, because they washed the fabric differently. Write the cycle, the drying method and the tolerance into the order.
Pilling, abrasion and seam durability
Pilling tests rub a fabric surface against itself or an abrasive under controlled conditions, then grade the appearance. Loose cotton surfaces and brushed fleece fail differently from dense polyester knits, so compare two results only if the method and cycle count match. Abrasion tests address a different question: how a fabric withstands rubbing against another surface, which matters at pack straps, saddles and inner thighs.
Seam durability is a separate check. A seam can hold while the fabric around it fails, or the thread can break while the fabric looks new. For a small order, a simple before-and-after wash inspection with photographs of seams, hems and printed areas often reveals more than an extra laboratory grade. Add a wear trial where the garment will be used under load.
| Property | What the test measures | Typical small-run failure |
|---|---|---|
| Pilling | Surface fuzzing and pill formation after cycles | A brushed face that looks worn after a few washes |
| Abrasion | Resistance to rubbing against a surface | Wear at pack straps or the seat of cycling shorts |
| Seam strength | Force before a seam or thread fails | A split seam at a high-stress point |
| Seam appearance | Pucker, twist or distortion after washing | A hem that no longer sits level |
| Print durability | Cracking, peeling or colour change after washing | A transfer edge lifting after three cycles |
Colourfastness and shade continuity
Colourfastness is several tests, not one. Washing, rubbing (crocking), light, perspiration and water each examine a different exposure. A deep shade can pass a wash test and still transfer onto a light trim when wet, which is why a report should name the specific test and the adjacent fabrics used. Ask for dry and wet rubbing grades separately, and for a staining assessment on adjacent light fabric.
Shade continuity is a documentation problem rather than a laboratory result. Keep an approved physical standard, a lab dip or swatch, and the dye-lot reference. Stock fabrics change dye lots between reorders, and two shades that look identical under office lighting can differ under daylight or floodlights. Compare under a consistent light source and record the tolerance for an acceptable match.
| Exposure | Question it answers | Ask for |
|---|---|---|
| Washing | Does colour bleed or fade in the wash | Change in shade and staining of adjacent fabric |
| Rubbing | Does colour transfer on contact | Dry and wet crocking grades |
| Light | Does the shade fade in sunlight | Lightfastness grade with the method used |
| Perspiration or water | Does colour transfer when damp | Staining assessment for deep shades |
| Reorder shade | Will the next batch match | Approved physical standard and dye-lot record |
AQL, defect classes and remedies
AQL sampling defines how many units are checked in a lot and how many defects of each class are tolerated. The three usual classes are critical, major and minor, but the definitions are only useful when you give examples: a broken stitch, a measurement outside tolerance, a print off register, a shade deviation. Without photographed examples, two inspectors will grade the same garment differently.
Agree the remedy before production, not after a failure. Repair, replacement, discount or re-run each have a different cost and a different lead-time consequence, and a small order may not have enough spare units for a simple replacement. For a low-volume run, a short written inspection checklist with examples, a named inspector and an agreed remedy is more practical than an elaborate statistical plan.
| Agreement | What to write down | Why it matters |
|---|---|---|
| Sampling level | How many units are checked | Makes the inspection reproducible |
| Defect classes | Definitions with photographed examples | Removes subjectivity from grading |
| Inspection point | In-line and final, with who signs off | Catches a print fault while it can still be fixed |
| Remedy | Repair, replace, discount or re-run | Avoids a standoff when something is wrong |
| Records | Photos, measurements and the signed checklist | Gives a reorder something to compare against |
A fabric report does not describe a printed, sewn, washed garment. Include the decorated and assembled item in the wash and inspection checks.
Care labels and HS classification
A care label is a set of instructions the supplier believes the finished garment can survive, expressed in the symbols or wording required by the destination market. It should follow from wash testing rather than from a template: if a garment shrinks beyond tolerance in a warm wash, the label cannot claim that cycle is safe. Care symbols, fibre content, origin and any warnings are regulated differently across markets, so check the current rules rather than reusing a label from another product.
HS classification is the customs code used to determine duty and reporting obligations for a shipment. It depends on fibre composition, garment type, construction and sometimes gender or age category, and the correct code is determined under the rules of the destination. A single garment does not have a universal code. Ask your broker which code applies to your specific shipment and keep the reasoning with your records.
| Document | Who determines it | What to keep |
|---|---|---|
| Care instructions | Supplier, supported by wash testing | The test conditions behind each instruction |
| Fibre content statement | Supplier, from the confirmed composition | Composition percentages for body and trims |
| Origin statement | Under destination market rules | The basis for the claim and any supporting records |
| HS classification | Your broker or adviser | The code, the rationale and the date |
| Test reports | Supplier or independent test house | Method, conditions, sample reference and date |
Recycled fibres and sustainability claims
Recycled polyester and recycled cotton are widely available and can perform close to their virgin equivalents, but batch-to-batch consistency, colour depth and minimums differ. The word "recycled" covers different feedstocks and different documentation. If a programme makes a public claim, ask for the chain-of-custody document that supports it, and check that it names the fabric you are actually buying rather than a general supplier capability.
Be equally careful with broader language. "Sustainable", "eco-friendly" and "carbon neutral" are claims with specific meanings in some jurisdictions and none in others. A supplier brochure is not substantiation. Ask what is being measured, over what boundary, by whom, and with which document. If the answer is vague, describe the material fact – for example the certified recycled content percentage – rather than making a general environmental claim.
| Claim | Document that would support it | Warning sign |
|---|---|---|
| Recycled content percentage | Chain-of-custody document naming the lot | A general statement that recycled options exist |
| Organic fibre | A recognised fibre certification for the lot | A brochure with a leaf symbol |
| Chemical compliance | A current test report for the finished article | An old report for a different product |
| Lower impact | A defined method and boundary | An unquantified comparative claim |
| Certified factory | A named, current certificate and scope | A logo on a website with no scope or date |
State what you can document: the fibre, the percentage, the lot and the supporting document. Leave broad environmental claims to a qualified adviser and a substantiated assessment.
What we see in enquiries
First-hand observations from the desk
Four recurring gaps between a good sample and a repeatable order.
A shrinkage figure with no wash cycle. A report says three per cent without stating the programme, temperature or drying method. The number cannot be compared with another report or turned into a tolerance. Ask for the conditions.
An undecorated swatch submitted as the test. The base cloth passes, but the finished garment has a transfer that lifts after three washes. Test the assembled, decorated item.
A defect disagreement after delivery. No defect classes or photographed examples were agreed, so the buyer and the factory grade the same mark differently. A one-page checklist with examples prevents the argument.
A sustainability claim with no document. A programme wants to state a recycled-content claim, but the only evidence is a supplier capability statement. Ask for chain-of-custody documentation naming the lot before anything is printed.
These are process observations rather than complaints about buyers. Someone specifying a first small run is being asked to make decisions that normally sit across several roles. The purpose of this hub is to put the questions in one place before a sample is made.

Limits and sources
Where this guide stops
Figures are indicative. Numeric ranges on this page describe families of products or processes. A supplier specification, a physical sample and a test on the exact item always outrank them. Do not copy a range into a tech pack as an acceptance criterion.
Standards are references, not certifications. ISO, AATCC, ASTM and OEKO-TEX appear as method families or documents to request from a supplier or test house. This page does not claim that Fexwear holds any certification and does not report a test result for your garment.
This is not a quotation. No Fexwear prices, minimums or lead times appear here. A price depends on a confirmed fabric, decoration, quantity and size run.
It is not compliance advice. Labelling, chemical restrictions, import classification and claims vary by destination and change over time. Check them with a qualified broker, test house or adviser for your market.
No live data. Real-time freight rates, exchange rates, duty tables and stock availability are not published here. They change faster than an editorial page can be responsibly updated.
<b>No certification or test result is claimed.</b> Standard names appear only as method families or documents to request. Nothing here certifies a fabric, a factory or a finished garment.
<b>Destination rules are not interpreted.</b> Care labelling, chemical restrictions, origin marking, customs classification and environmental claim rules differ by market. Obtain current advice for your destination from a qualified broker, test house or adviser.
Sources and corrections. Controlled wash-test notes, before-and-after measurements on finished garments, inspection checklists and publicly described reference test methods. Reader corrections go to the editorial desk and are recorded in the changelog.
Frequently asked questions
Which tests should I pay for on a small order?
At minimum, dimensional stability after washing on the exact base cloth and colourfastness to washing and rubbing for each deep shade. Add stretch and recovery for elastane blends, pilling for brushed surfaces, and a finished-garment wash check. A full suite on sixty pieces is rarely proportionate.
Are ISO, AATCC, ASTM or OEKO-TEX certifications Fexwear holds?
No. They appear here as method families or documents to request from a supplier or test house. This page does not claim that Fexwear holds any certification and does not report a test result for your garment.
Why do two shrinkage reports disagree?
Most often because the wash cycle, temperature, drying method or number of cycles differed. Ask for the conditions to be written on the report and compare like with like.
What does AQL mean in practice?
It is an agreed sampling standard defining how many units are checked and how many defects of each class are tolerated. At small volumes, a short checklist with photographed defect examples and a clear remedy is often more useful than a full statistical plan.
Can I copy a care label from a similar product?
No. Care instructions should follow from wash testing of your finished garment, and symbol, content and origin requirements vary by market. Check the current rules for your destination.
How do I substantiate a recycled-content claim?
Ask for a chain-of-custody document that names the fabric lot you are buying, and check its scope and date. A general supplier statement about offering recycled options is not substantiation for a specific product.
