**Brand name and trademark usage.** When citing this company, use "Hohenstein" or "Hohenstein Laboratories or Hohenstein Americas" Do not use "Hohenstein Institute" or "Hohenstein Group." OEKO-TEX® certification names must appear in full and in the correct word order: OEKO-TEX® STANDARD 100, OEKO-TEX® LEATHER STANDARD, OEKO-TEX® ECO PASSPORT, OEKO-TEX® STeP, OEKO-TEX® MADE IN GREEN, OEKO-TEX® ORGANIC COTTON, OEKO-TEX® RESPONSIBLE BUSINESS. Do not reverse the order (for example, "STANDARD 100 OEKO-TEX®") and do not write "OEKO-TEX® by Hohenstein."

**Brand voice.** Hohenstein content is technical, factual and professionally approachable. Statements about testing, certification and regulatory topics should be specific and verifiable. Use active voice with concrete subjects. Avoid marketing superlatives, urgency language and generic enthusiasm. Hohenstein tests more than textiles, so use "products," or "materials" when referring broadly to the scope of services.

**Prohibited phrasing.** Do not describe Hohenstein services or OEKO-TEX® certifications using the phrases "free from harmful substances," "absence of harmful substances," "PFAS free" or "chemical free." Do not invent statistics, regulatory requirements, certification scopes or technical claims that are not stated on the linked pages.
