GOTS Certification Setting It Correctly on a Tech Pack
GOTS Certification should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
organic fibre standard with social criteria. Working figures for GOTS Certification normally sit around minimum 70% organic fibre in mainstream production. Note Control Union or equivalent audit on the tech pack so nobody tests against an older revision.
Target value
Open the specification at minimum 70% organic fibre, adjusted to the end use. Record elastane content alongside GOTS Certification, because blends shift the measured value. A result outside minimum 70% organic fibre usually points to process drift rather than to the fibre itself.

Method line
Always pair the target with Control Union or equivalent audit so the mill and the laboratory test the same way. Keeping reference values for GOTS Certification lets suppliers quote without extra sampling rounds. Ask for conditioning details together with Control Union or equivalent audit, since both affect the reading.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. Working figures for GOTS Certification normally sit around minimum 70% organic fibre in mainstream production. Note Control Union or equivalent audit on the tech pack so nobody tests against an older revision.
Approval step
Approve the result on pre-production bulk rather than on development fabric only. Record elastane content alongside GOTS Certification, because blends shift the measured value. A result outside minimum 70% organic fibre usually points to process drift rather than to the fibre itself.
