AZO Dye Restrictions Why Shipments Get Rejected Over This
Many disputes come down to AZO Dye Restrictions. Below is what inspectors check and why shipments fail.
The core definition
ban on cleavable aromatic amines. Working figures for AZO Dye Restrictions normally sit around below 30 ppm per amine in mainstream production. Note EN 14362 determination on the tech pack so nobody tests against an older revision.
Most common cause of failure
Results usually fall outside below 30 ppm per amine because the target was never written into the order. Record elastane content alongside AZO Dye Restrictions, because blends shift the measured value. A result outside below 30 ppm per amine usually points to process drift rather than to the fibre itself.
How it is checked
Inspection and laboratory work both refer to EN 14362 determination. Keeping reference values for AZO Dye Restrictions lets suppliers quote without extra sampling rounds. Ask for conditioning details together with EN 14362 determination, since both affect the reading.
Related faults
failure leads to shipment rejection, so related complaints often point back to this single parameter. Working figures for AZO Dye Restrictions normally sit around below 30 ppm per amine in mainstream production. Note EN 14362 determination 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 AZO Dye Restrictions, because blends shift the measured value. A result outside below 30 ppm per amine usually points to process drift rather than to the fibre itself.
