GOTS Certification How to Read It on a Lab Report
Laboratory reports present GOTS Certification in a compact format. Knowing what each line means prevents misreading.
Definition reminder
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.
Common report layout
The report states method Control Union or equivalent audit, sample description, conditioning, and the measured result. 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.
Typical result
Values near minimum 70% organic fibre usually indicate a conforming lot, assuming the fabric matches the sample submitted. 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.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. 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.
Questions to ask
Ask the laboratory for the standard revision and sample description before accepting or rejecting a result. 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.
