Goose-down briefs with opaque shells
Start by confirming why goose down is specified: material policy, an existing approved design or a performance target. Then evaluate the recovered lot against that requirement. Grey coloration should be assessed separately from composition, odor, cleanliness and loft.

Certification and documentation
GRS-certified options available. Certification availability depends on the product, order and transaction scope. Request current documents for the relevant legal entity and material before approval.
OEKO-TEX STANDARD 100 coverage must be confirmed for the supplied material. RDS addresses a different certification scope and is not evidence that a material is recycled.
From sample to supply
Share the end product, destination market, expected quantity and your specification sheet. A representative material sample and a finished-product trial help establish an approval reference. Sample terms, availability and timing require confirmation.
Agree packaging, moisture protection, identification and supporting documents before ordering. Retain a reference sample and associate it with the approved lot and test report.

Questions, answered.
Can this material replace an existing virgin goose-down fill?
It needs qualification against the existing specification and finished product. Compare methods, composition, loft, cleanliness and documentation before approving substitution.
Can I download an approved specification sheet?
A verified public specification sheet is not yet available. Use Request Specification to prepare your requirements; the preview form does not send inquiries.
