Standard Reconciliation Protocols for Chain of Custody Documentation
Verify physical receiving weights against transaction certificate balances using standard moisture regain adjustments before authorizing batch production.
GRS 4.0
Standard Definition
International certification frameworks for recycled textiles measure recycled material content while mandating specific social and environmental operational standards across the manufacturing supply chain. Promulgated by Textile Exchange, grs 4.0 specifies full supply chain traceability and social responsibility requirements for products containing at least 20 percent recycled content. The standard governs raw material inputs and wastewater output from recycling facilities to garment manufacturers.
It does not apply to raw material collection points prior to recycling or retail store operations.
Social Assessment
Facilities operating under this standard must demonstrate compliance with fundamental labor rights and workplace safety criteria. Audits conducted for grs 4.0 evaluate working hours and fair compensation across yarn spinning and wet processing plants. Verification includes payroll reviews and facility inspections.
Non-compliance with core international labor standards leads to immediate certificate suspension for the facility.
Chemical Restriction
Processing facilities must restrict hazardous substances during manufacturing to protect worker safety and environmental health.
Compliance Margin
Certification requirements apply strictly to facilities handling products with verified recycled inputs through continuous chain of custody tracking. Under grs 4.0, consumer-facing product claims require a minimum of 50 percent recycled content, despite facility-level certification starting at 20 percent. Blending certified recycled fiber with uncertified virgin fiber requires rigorous mass balance accounting to prevent false claims.
Inaccurate mass balance logs result in immediate audit failure and withdrawal of transaction certificates.
