Quality & compliance

Certificates are only useful if they survive an audit

We issue documentation at lot level, not just a logo on a website. Every bulk shipment leaves the mill with inspection reports, test results where relevant, and the certificate chain your retailer will ask for.

In short

All apparel fabrics are OEKO-TEX Standard 100 certified, recycled qualities are GRS 4.0 with transaction certificates, organic cotton is GOTS 6.0, and the mill is audited to ISO 9001 and amfori BSCI.

Certifications

What each certificate covers — and what it does not

Buyers are often shown a certificate that does not actually support the claim being made. This table is how we explain the difference to our own customers.

Yunhong certifications, their scope and their limitations
CertificateWhat it provesWhat it does not cover
OEKO-TEX® STANDARD 100Finished article tested for harmful substances, product class II (and class I for babywear on request).Does not cover working conditions, environmental management or recycled content.
GRS 4.0Recycled content, chain of custody, chemical restrictions, social and environmental criteria.A scope certificate alone is not enough — a transaction certificate is required per shipment.
GOTS 6.0Organic fibre content (70% minimum), processing chemistry, wastewater and social criteria across the chain.Both the fabric mill and the garment factory need scope certificates.
bluesign® APPROVEDChemical input management for selected performance finishes.Applies to the approved process, not automatically to every fabric we weave.
ISO 9001:2015Quality management system, audited annually by a third-party certification body.Process discipline, not product performance.
amfori BSCISocial compliance audit covering working hours, wages, safety and freedom of association.Current rating A, audited every two years.

Certificate numbers, expiry dates and audit reports are available on request once an NDA is in place. Ask our compliance team.

Testing

The tests we run on every lot

Physical performance is tested in our own lab and confirmed by a third-party laboratory for new developments and annual re-validation.

Four-point inspection on every roll

Every metre is inspected on a four-point system before packing: defects are scored by size and frequency, and a roll that exceeds the agreed points per 100 square yards is cut back or replaced. Rolls are measured on the machine, not estimated.

The inspection report travels with the goods and lists roll numbers, actual metres, defect points and any short rolls. If your QC team re-inspects on arrival, you are comparing against our numbers rather than starting from zero.

Shade control on repeat orders

We keep a physical standard of every approved lot for 24 months and dye repeats against that standard, measured on a spectrophotometer to ΔE ≤ 1.0. This is why a third repeat matches the first even if the shade card has been updated in between.

If something is wrong

Send photographs, roll numbers and the inspection sheet. Verified defects above 1.5% of shipped metres are credited or replaced, and we cover return freight on a confirmed claim. Our target is a first response within one business day and a resolution plan within five.

Questions

Compliance questions we answer weekly

Are your fabrics OEKO-TEX certified?

All apparel fabrics in our range are OEKO-TEX Standard 100 certified to product class II, with a valid certificate on file. Babywear constructions can be tested to class I on request. Test reports are issued with each bulk shipment.

What certifications and audits does your factory hold?

We hold OEKO-TEX Standard 100, GRS 4.0, GOTS 6.0, ISO 9001:2015 and bluesign® APPROVED, and we are audited under amfori BSCI with a rating of A. Certificates and audit reports are available on request under NDA.

How do you control shade consistency across repeat orders?

We retain a physical standard of every approved lot for 24 months, dye repeats against that standard, and measure shade with a spectrophotometer to a tolerance of ΔE ≤ 1.0. Repeat orders are matched to your original approved lot, not to the shade card.

What is your fabric defect policy?

Every roll is inspected on a four-point system before packing, and inspection reports ship with the goods. Verified defects above 1.5% of shipped metres are credited or replaced, and we cover return freight on a confirmed claim.
