OEKO-TEX Standard 100: What It Means for Hemp Apparel Importers

OEKO-TEX Standard 100 is the most widely recognised textile safety certification in the global apparel market. For buyers sourcing hemp clothing from Nepal, understanding what the certification covers -- and what it does not -- prevents compliance surprises when your product reaches retail.

What is OEKO-TEX Standard 100?

OEKO-TEX Standard 100 is a product-level certification issued by OEKO-TEX Association member institutes (Hohenstein, TESTEX, and others). It certifies that every component of a finished textile product -- fabric, thread, buttons, labels, dyes, and finishes -- has been tested against a restricted substances list (RSL) and found free of harmful chemicals at legally and scientifically defined limits.

The certification applies to product classes based on skin contact:

• Class I: Products for babies and toddlers (under 3 years)
• Class II: Products worn next to skin (underwear, t-shirts, bed linen)
• Class III: Products not directly in contact with skin (outer jackets)
• Class IV: Decoration materials (curtains, furniture fabric)

Hemp tees and hoodies typically certify at Class II, which has the most stringent limits.

What it covers

OEKO-TEX Standard 100 tests for over 100 substances, including:

• Azo dyes that can release carcinogenic aromatic amines
• Formaldehyde (residues from wrinkle-resistant finishes)
• Heavy metals (chromium, cadmium, lead, mercury, arsenic, antimony, copper, cobalt, nickel)
• Pesticide residues on natural fibres
• Phthalates (in synthetic components)
• pH value (outside 4.0-7.5 triggers skin irritation)
• Colour fastness (rubbing, perspiration, washing)

For undyed hemp-cotton garments (the colourways used in ApexVectura's HC range), the key tests are pesticide residues, pH, and heavy metals. No azo-dye testing is required for undyed goods, which simplifies certification.

How to verify a certificate

Every OEKO-TEX Standard 100 certificate has a unique article number in the format XX OEKO-TEX CertNo. Buyers can verify any certificate at oeko-tex.com -- enter the article number and confirm:

1. The certificate is active (not expired)
2. The certified product description matches what you are ordering
3. The certifying institute is an OEKO-TEX member

Certificates are valid for 12 months and must be renewed annually. Always request the current certificate number, not a copy of a previous year's certificate.

What the certificate does NOT cover

• Social and labour standards -- OEKO-TEX Standard 100 is a chemical safety standard only. For labour compliance, look for GOTS (Global Organic Textile Standard) or Fair Trade certification, which include supply chain audits
• Organic fibre sourcing -- Standard 100 certifies chemical safety, not whether the underlying hemp or cotton was organically grown. GOTS covers both chemical safety and organic farming
• Country of origin -- The certificate does not confirm Nepal origin. That comes from the Certificate of Origin issued by Nepal Commerce

Hemp-specific considerations

Hemp fibre naturally tests clean for most OEKO-TEX RSL substances -- it is naturally pest-resistant, so pesticide residue levels are typically lower than cotton. The areas that require specific attention in hemp processing:

Retting

Hemp fibre is separated from the stalk by retting (water or dew retting). Water-retted hemp, if not properly processed, can carry microbial load. The certification testing covers this, but ensure your supplier uses properly controlled retting.

Blended yarn

If your hemp garment uses a hemp-cotton blend, both fibres are tested. Organic cotton from certified supply chains has lower residue risk. Non-organic cotton in a blend can introduce pesticide residues (particularly chlorpyrifos and permethrin) that affect certification outcome.

Dyeing (if applicable)

For dyed hemp apparel (not the undyed ApexVectura range), the dye choice is critical. Reactive dyes have a significantly better OEKO-TEX pass rate than vat dyes or sulphur dyes, which can introduce sulphur residues and colour fastness failures.

Buyer checklist

Before placing an order for OEKO-TEX certified hemp apparel from Nepal:

1. Request the article number -- not just a PDF of the certificate
2. Verify it at oeko-tex.com -- confirm active status and matching product description
3. Check the certificate class -- Class II for adult apparel next to skin
4. Confirm all components are covered -- thread, labels, and any trims must be listed
5. Check expiry date -- certificates expire 12 months from issue; orders placed close to expiry may ship after the renewal window

ApexVectura provides the current OEKO-TEX article number and full certificate documentation with every hemp order. For initial enquiries, the certificate is available on request before PO placement.
