What OEKO-TEX Product Class 1 actually means
OEKO-TEX Standard 100 has four product classes. Class 4 covers decorative materials with no skin contact. Class 3 covers outer fabrics. Class 2 covers garments worn close to the skin by adults. Class 1 — the most stringent — covers all textiles intended for babies and children under 36 months, and products with prolonged direct skin contact.
Class 1 tests for over 100 potentially harmful substances, including formaldehyde, heavy metals including cadmium, lead and chromium, pesticide residues, allergenic dyes, and pH levels outside safe skin contact ranges. The certification is granted by an authorized independent institute, not self-declared, and is renewed through annual testing. Every yarn we use in woven labels carries this certification.
