GOTS governs processing from spinning to finished goods, including restricted chemicals, wastewater treatment, and social criteria, while requiring certified organic fiber inputs. OCS only tracks content. For luxury projects, prioritize GOTS where possible, and verify transaction certificates to prevent dilution between mills and converters.

For viscose, modal, and lyocell, fiber credibility starts with pulp. Prefer FSC or PEFC certified sources and consult CanopyStyle rankings to avoid high‑risk forests. Confirm chain‑of‑custody numbers on invoices and ensure mills disclose solvent recovery, sulphur emissions, and wastewater quality alongside design particulars.

OEKO‑TEX STANDARD 100 tests finished goods for harmful substances; Eco Passport screens chemical inputs; Bluesign addresses process stewardship. Pair these with GREENGUARD Gold or Indoor Advantage Gold for finished spaces. Combine results with VOC declarations to satisfy LEED, WELL, or BREEAM credits without compromising tactile luxury.
Embed clear requirements: certified fiber origin (GOTS scope number or FSC license), ZDHC MRSL conformance, target abrasion (Martindale or Wyzenbeek), lightfastness, and verified chain‑of‑custody documentation with each shipment. Add substitution rules and approvals, ensuring performance or certification cannot be quietly diluted when budgets tighten.
Issue memo samples with provisional IDs tied to documentation. Confirm performance via ISO or ASTM methods—lightfastness, pilling, seam slippage, dimensional change, and VOC emissions where relevant. Record decisions in a shared tracker so project teams, vendors, and clients reference the same, timely, audited information.
Check that names on certificates match legal suppliers, that dates cover production windows, and that product descriptions align with actual constructions and weights. Verify seals on both goods and paperwork. When something feels off, pause procurement and ask the certification body for written clarification.
Adopt QR‑linked batch IDs, RFID tags, or digital product passports that carry fiber origin, certifications, chemistry, and care guidance. Platforms like TextileGenesis or EON can help. Share links with clients so provenance, testing, and maintenance live beyond memos, moodboards, and handover binders.
Avoid absolutes and inflated comparisons. Present reasoning, data sources, and remaining questions, and invite clients to prioritize what matters most—animal welfare, carbon, water, or longevity. Encourage comments and subscriptions, then report back after installation with measured outcomes and care tips that extend the textiles’ life.
