# Upstream Viscose Material Traceability and OEKO-TEX Scope

Selected upstream viscose-yarn suppliers have provided current OEKO-TEX STANDARD 100 records for defined yarn scopes. This is material-source due-diligence evidence only. It does not certify WonderCloth, every finished cleaning cloth, downstream processing or all SKUs.

- Xinjiang Zhongtai Zhenlun Textile Co., Ltd.: SH005 128829, valid to 2027-05-31; 100% white viscose yarn; Product Class I / Annex 6.
- Xinxiang Chemical Fibre Co., Ltd.: SHYO 032988, valid to 2026-12-31; specified viscose rayon filament yarn/thread scope; Product Class I / Annex 6.

For each order, confirm the supplier relationship, yarn specification and lot, finished-product composition, processing scope and destination-specific tests. BaiLu-ECO material is supplier background only; it does not independently prove recycled content, RCS, carbon footprint or finished-product certification.
