Specification before color
Grey down can be considered where shell opacity makes color less critical. Color does not establish fill power, cleanliness or warmth. Compare tested lots under the same method and review appearance in the finished construction.

Quality checks before approval
Testing should refer to the material lot and the agreed acceptance criteria. CIRCUDOWN has in-house laboratory capabilities; third-party testing can be arranged with IDFL, SGS, QTEC and Guangjian.

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.
Does grey down have lower insulation performance?
Color alone does not establish insulation performance. Compare measured fill power, composition, fill weight and the finished product design.
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.
