Restricted Substances List (RSL) Why Shipments Get Rejected Over This
Many disputes come down to Restricted Substances List (RSL). Below is what inspectors check and why shipments fail.
The core definition
list of banned or limited chemicals. Working figures for Restricted Substances List (RSL) normally sit around reviewed each season in mainstream production. Note brand-specific published list on the tech pack so nobody tests against an older revision.
Most common cause of failure
Results usually fall outside reviewed each season because the target was never written into the order. Record elastane content alongside Restricted Substances List (RSL), because blends shift the measured value. A result outside reviewed each season usually points to process drift rather than to the fibre itself.

How it is checked
Inspection and laboratory work both refer to brand-specific published list. Keeping reference values for Restricted Substances List (RSL) lets suppliers quote without extra sampling rounds. Ask for conditioning details together with brand-specific published list, since both affect the reading.
Related faults
suppliers must test against the current version, so related complaints often point back to this single parameter. Working figures for Restricted Substances List (RSL) normally sit around reviewed each season in mainstream production. Note brand-specific published list on the tech pack so nobody tests against an older revision.
Avoiding rejection
Agree targets, tolerances and the method before production, then test per lot rather than per shipment. Record elastane content alongside Restricted Substances List (RSL), because blends shift the measured value. A result outside reviewed each season usually points to process drift rather than to the fibre itself.
