Period underwear manufacturers should have textile safety certificates, chemical compliance reports, quality systems, and social audit documents. The most important documents are OEKO-TEX Standard 100, PFAS test reports, REACH/SVHC declarations, CPSC flammability compliance for the US, BSCI or SMETA audits, and ISO 9001.

For buyers, the key rule is simple: certificates must match the actual product, material, color, and production batch.

Quick Answer

OEKO-TEX Standard 100

OEKO-TEX Standard 100 is one of the most important certifications for period underwear. It shows that textile components have been tested for harmful substances.

For period underwear, buyers should check whether the certificate covers:

• Body fabric

• Gusset fabric

• Absorbent layer

• Leakproof layer

• Elastic

• Thread

• Labels

• Dyes and finishing chemicals

Do not accept a generic fabric certificate if your finished product uses different layers or trims.

The upstream dyeing factory of ljvogues provides the oeko certificate.

PFAS Test Report

A PFAS test report is essential for period underwear sold into stricter textile markets. PFAS chemicals are a major concern in functional textiles because they have been used for water resistance, stain resistance, and performance finishes.

California AB 1817 restricts regulated PFAS in new textile articles from January 1, 2025. Buyers selling into the US should ask for product-specific PFAS testing and a certificate of compliance.

A good PFAS document should include:

• Testing lab name

• Sample description

• Test method

• Detection limits

• Date of testing

• Exact material or product tested

• Authorized signature

REACH And SVHC Compliance

REACH/SVHC compliance is important for period underwear sold in the European Union. REACH controls chemical substances in products placed on the EU market. SVHC refers to substances of very high concern.

Buyers should request:

• REACH compliance declaration

• SVHC declaration

• Restricted substance test reports

• Material safety documentation when needed

This is especially important for dyed fabrics, prints, coatings, adhesives, and leakproof membranes.

CPSC 16 CFR Part 1610

CPSC 16 CFR Part 1610 is important for clothing textiles sold in the United States. It covers flammability requirements for apparel textiles.

Period underwear is worn as apparel, so US buyers should confirm that the fabric complies with applicable flammability rules.

For children’s or teen period underwear, buyers should also review CPSIA-related requirements, including lead and phthalate rules where applicable.

BSCI Or SMETA

BSCI and SMETA help buyers evaluate factory social responsibility. They are not product safety certificates. They are factory audit systems.

BSCI is connected with supply chain social performance. SMETA, developed by Sedex, reviews labor standards, health and safety, environment, and business ethics.

Large retailers often ask for one of these audits before approving a supplier.

ISO 9001

ISO 9001 shows that a factory has a quality management system. It does not prove that one period underwear style is leakproof or PFAS-free. It proves that the factory has documented quality processes.

For period underwear buyers, ISO 9001 is useful when combined with:

• Incoming material inspection

• Inline production inspection

• Finished goods inspection

• Absorbency testing

• Wash testing

• Leakage testing

• AQL inspection

  

GRS, RCS, GOTS, And OCS

Material-claim certifications are needed when your brand makes sustainability claims. Do not claim recycled, organic, or sustainable materials unless the supply chain documentation supports it.

Use these documents carefully:

• GRS: for recycled material and chain of custody

• RCS: for recycled content claims

• GOTS: for organic textile claims

• OCS: for organic content verification

If your brand sells recycled nylon period underwear, ask whether the supplier has valid GRS or RCS transaction documentation.

ISO 14001

ISO 14001 is useful for buyers that care about environmental management. It does not replace product testing, but it shows that the factory has an environmental management system.

Retail buyers may ask for ISO 14001 when evaluating long-term suppliers.

What Certifications Are Not Enough?

A certificate is not enough if it does not match your product. This is one of the biggest sourcing risks in period underwear.

Watch for these red flags:

• The certificate belongs to another factory

• The certificate is expired

• The certificate covers fabric only, not the finished product

• The test report is for a different color

• The report does not include the leakproof layer

• The supplier says “FDA certified” for normal underwear

• The factory refuses batch-level testing

FAQ

What certification is most important for period underwear?

OEKO-TEX Standard 100 and PFAS test reports are the most important safety documents for period underwear.

Does period underwear need FDA certification?

Usually no. Normal period underwear is apparel. FDA review may become relevant only if the product is marketed with medical claims.

Is OEKO-TEX enough for PFAS-free claims?

OEKO-TEX is useful, but buyers should still request PFAS-specific reports for strict markets.

What audit should a factory have?

BSCI or SMETA is commonly requested for social compliance and retailer approval.

Should test reports be product-specific?

Yes. Reports should match the actual fabric, gusset, leakproof layer, color, and production batch.
