Why intimates carry a higher documentation bar
Underwear and bras are worn against skin for hours and laundered often, so both regulators and retail buyers treat their fabric documentation as an entry condition rather than a marketing extra. A program that cannot produce a current certificate per lot will struggle at plant audit, at customs in some markets and at retailer onboarding. The documents are also the buyer's protection in disputes: a pH result or a composition line on a report settles arguments that memory cannot.
OEKO-TEX Standard 100: the baseline
OEKO-TEX Standard 100 is the certificate most intimates buyers ask for first. It screens more than 300 harmful substances - from formaldehyde content and heavy metals to certain colorants - and it applies from yarn through threads, elastics and trims to the finished product, not to the face fabric alone. For a bra that scope matters: the elastics, the hooks and the lace all fall inside it. Certificates are issued per lot and held by the partner plant; the desk verifies each document per project and files it with the shipment record. Buyers comparing fabric options can read the Standard 100 explainer for scope and limits.
United States: fiber and care labels
Two US rules shape the retail unit. The Textile Fiber Products Identification Act requires fiber content by percentage, country of origin and an RN number on the label; a garment made of cotton and elastane needs those percentages stated in the prescribed order. The FTC Care Labeling Rule requires care instructions a consumer can follow - washing temperature, drying method, bleach guidance - and for intimates those instructions should match the elastics and lace, not just the shell fabric. Printed or tagless labels carry the same obligations as sewn-in ones, which matters because many programs now prefer printed internals for comfort.
Flammability: 16 CFR 1610
General wearing apparel sold in the United States falls under 16 CFR 1610, the Standard for the Flammability of Clothing Textiles. Fabrics are tested and results read as classes per the test report; the class determines whether the garment can be sold and what labeling, if any, it requires. Intimates sit squarely inside the scope of the rule, and the practical step for a program is simple: keep a current test report per fabric, per lot, in the shipment file. Children's lines add separate rules, covered below.
European Union: REACH and SVHC
For EU shipments, REACH is the framework that matters. Substances of very high concern on the candidate list are screened in the shipment file, and importers carry the duty to check - which makes per-project document verification more than ceremony. A program planned for both the US and the EU runs the widest route: OEKO-TEX as the fabric baseline, US labels on the American units, REACH screening for the European file. The REACH for exporters guide walks the importer side in detail.
Test items agreed per order
Beyond the certificates, each order names the test items that will be run and the acceptance levels. Typical items for intimates: color fastness to washing and rubbing, shrinkage, pH value, formaldehyde content, pilling resistance, elastic recovery, side wing stretch and, for period lines, gusset absorption. Agreeing the list before production is what makes the pre-shipment inspection objective rather than a matter of opinion.
| Document or test | Scope | What it evidences |
|---|---|---|
| OEKO-TEX Standard 100 | Yarn, trims, finished lot | 300+ harmful substances screened |
| Textile Act label | US retail units | Fiber content, origin, RN number |
| FTC care label | US retail units | Care instructions matching the build |
| 16 CFR 1610 report | Apparel fabrics | Flammability class per test report |
| REACH SVHC file | EU shipments | Candidate-list screening per shipment |
| GOTS or BCI certificate | Where specified | Organic or better-cotton claim per lot |
Children's lines and sustainability claims
Two additions apply selectively. Where a line serves children, CPSIA adds tracking labels and children's product certificate requirements on top of the general textile rules. Where a program makes a sustainability claim - organic cotton, better cotton - the claim is only as strong as its certificate: GOTS or BCI documentation per lot, with wording on the listing that matches what the certificate covers. An unverifiable claim is worse than no claim, because it invites exactly the scrutiny the program was trying to avoid.
Who holds what, and when
Lissea holds no certificates. Partner plants hold them per lot; the desk verifies the documents per project, checks that certificate scopes match the materials actually used, and files everything with the shipment. The testing and inspection page shows where verification sits in the lot flow, and the certifications checklist condenses this page into a list a buyer can send straight to a plant. When a route is unclear for a market, start from the quote form and the desk will map it per program.
