PFAS and BPA in yoga wear: ask for evidence, not reassurance
Chemical scrutiny of activewear moved from headlines to regulators in 2026. What OEKO-TEX Standard 100 proves, what it does not cover, why PFAS needs a lab report rather than a certificate, and the exact documents to ask a supplier for.
Read guideTop 8 criteria for choosing a multi-category activewear supplier (2026)
Ranked criteria for brands sourcing leggings, bras, swim and accessories together — what to verify, the questions that expose a weak answer, and the warning signs that a supplier only manages one category well.

Why mixed-category ranges arrive to four different definitions of acceptable, how AQL 2.5 works in practice, and what changes when the inspector's obligation runs to the buyer instead of the producer.
Read guideWhat a supplier's colour and trend input is actually worth
Seasonal colour cards from a supply chain answer a different question than a trend report — not what is fashionable, but what can be dyed consistently at your quantity. How to use supplier colour input, and where its limits are.
Read guideRestricted substances and azo dyes: how to make a supplier prove it
Azo dyes, formaldehyde, nickel and heavy metals are regulated in the EU and elsewhere. What the rules cover, why a certificate is a starting point rather than proof, and how to write a substance requirement a supplier cannot answer with reassurance.

Sourcing strategy
Bulk arrived wrong: what each of your four options costs
The bulk is wrong and the supplier has offered a discount. Four real options — accept, rework, reject, or walk away from the deposit — priced honestly, including the one nobody writes about: when paying the balance is throwing good money after bad.
Read the guide 02When a supplier asks to be paid off-platform, or in Hong Kong
Suppliers are asking to be paid outside the platform, or into a Hong Kong company. Some of that is a real compliance cost being passed on; some of it is not. The names that have to match, and the questions that tell the two apart.
Read the guide 03When to use a sourcing partner — and when to go direct
A buyer-side sourcing partner coordinates factories, QC and shipment behind one contact — sometimes worth the layer, sometimes not. A plain decision framework for when a partner beats going factory-direct, and when you should skip one like SEAMDANCE.
Read the guide 04Who carries the risk when you don't own the factory
Buy direct and you wire the deposit and balance yourself, carrying the counterparty risk. Buy through a partner and one party contracts on your behalf. How payment terms, QC liability and currency risk shift — and what to hold before releasing the balance.
Read the guide 05Supplier network vs single factory: the continuity risk
Many growing brands tie their whole range to one factory and only feel the risk when it bites — a full peak season, a price rise after lock-in, a failed audit. How a managed network spreads continuity risk, and when one factory is still the right call.

Read the guide 20Why suppliers don't reply to your first message
Fifty enquiries, a handful of replies, none of which read the tech pack. What the supplier is deciding in the first ten seconds, and how to write a first message that survives it.
Read the guide 21Vetting a sourcing agent when every reply is a pitch
Ask where to find a trustworthy sourcing agent and twenty strangers answer "DM me". The questions below produce verifiable answers instead of claims — including when we apply them to ourselves.
Read the guide 22Why activewear needs a different manufacturer from the rest of your line
The factory that makes your tees genuinely cannot make your leggings — not won't, cannot. Four pieces of equipment and one test regime separate the two, and knowing which is missing tells you whether a quote is real.
Read the guide 23Activewear manufacturers in China (2026): what each one actually publishes
Most rankings of Chinese activewear factories are published by Chinese activewear factories, and five of the six we found put themselves first. This one names no winner — it reports what each company publishes about MOQ, certification and ownership, checked against their own sites.
Read the guide 24Low-MOQ activewear manufacturers: what the small numbers actually mean
Published minimums for China activewear run from 50 pieces to 3,000. The low ones are real but conditional — they attach to stock styles, single colours or a wholesale tier, and the number changes the moment you customise.

Quality + compliance
A supplier sent you a certificate: how to check it in ten minutes
A certificate PDF lands in your inbox. Five checks in order — holder, scope, validity window, public database, and whether it reaches your order — what each one rules out, and what to write into the order before bulk.
Read the guide 02Why a passed AQL batch can still break your marketplace metric
AQL 2.5 is a limit for accepting a shipment. A marketplace defect rate is a ceiling on customer-visible failures. They measure different things, and on a 300-unit order the gap between them is arithmetic you can do yourself.
Read the guide 03Your care label is a legal claim. Where is your evidence?
“Machine wash cold, tumble dry low” copied off a spec sheet is a claim with nothing behind it. What the FTC's reasonable basis requirement means for activewear, why silence is not a warning, and how to test during sampling.
Read the guide 04Compliance testing on a small run: a multiplication, not a number
What laboratory testing actually costs for one small-run activewear style — worked out loud across three colourways and a contrast zip, divided across a 300-unit first order, with indicative published ranges.
Read the guide 05Fibre content on the label: the mill's number, your liability
An EU market-surveillance campaign found 37% of clothing samples non-compliant on fibre content, and blended fabrics failed at 64%. Why activewear composition drifts in production, and what to put in the specification before it does.
Read the guide 06PFAS thresholds by market: why “PFAS-compliant” means nothing
California's ceiling is 100 ppm total organic fluorine. France's is 25 ppb for one targeted PFAS. The same legging, more than three orders of magnitude apart — and in every one of these markets the brand is the party that signs.
Read the guide 07PFAS in leggings: Prop 65 settlements are stricter than the law
California's apparel ban sets 100 ppm total organic fluorine, falling to 50 ppm in 2027. Prop 65 settlements already require under 50 ppm total fluorine on pants and skirts — a broader measure, in force now.
Read the guide 08Spandex is not an exempt fiber: 16 CFR 1610 for activewear
Polyester is on the exempt fiber list. Spandex is not — so a poly-spandex knit does not qualify at any ratio. What 16 CFR §1610.1(d) really exempts, why brushed fabrics lose the exemption entirely, and what to confirm before briefing a lab.

The DPP data you cannot get later: who holds which fact
The passport will ask which mill knitted your fabric and which dye house coloured it. Those facts sit with five or six separate parties, none of whom keeps them for you — and they get harder to retrieve every month after production.
Read the guide 02The cheap DDP quote that can cost 20% of your goods value
A DDP price can look a few hundred pounds cheaper and still leave a VAT-registered UK or EU brand with no import evidence in its own name — because the entry was never in its name. The mechanics, and the three questions to ask.
