从Hong Kong供应商批量进口90% Grey Duck'S Down

90% Grey Duck's Down from Huayu Feather Industrial Co., Ltd. consists of 90% down cluster content with 10% feather, derived from grey ducks. The source material highlights thermal efficiency, lightweight composition, and water-resistant treatment as core performance attributes. Fill power, the critical measure of loft and insulation value, is referenced though no specific cuin figure is stated in the source data. This grade sits within the premium insulation tier, where down cluster percentages above 85% command stronger performance in cold-weather applications.

The grey duck down category typically presents a darker base tone than white duck down, which influences finished product aesthetics and lining requirements. The down clusters themselves comprise plumulaceous filaments that trap air without significant weight, a property measured by fill power ranging from 550 to 800+ cuin for comparable grades. Water-resistant treatment, mentioned in the source, usually involves a durable water repellent (DWR) finish applied to individual clusters to maintain loft under humidity. Standard industry testing for such material includes turbidity (cleanliness), oxygen number (fat residue), and species identification to prevent adulteration with lower-grade fills. The 90% cluster ratio indicates minimal feather content, reducing quill pokes and improving overall compressibility.

Buyers in outdoor apparel, luxury bedding, and camping equipment sectors source this material for winter jackets, insulated jackets, and high-performance sleeping bags. The lightweight characteristic suits ultralight gear where warmth-to-weight ratios determine product positioning. Sourcing from Huayu Feather Industrial Co., Ltd. involves confirming actual fill power measurements, turbidity grades, and treatment durability through sample evaluation. The supplier's branch office location in Guangzhou suggests mainland China manufacturing with Hong Kong commercial registration, a common structure in the feather and down trade.

Huayu Feather Industrial Co., Ltd. operates from a branch office at North.628 Avenue Mid International Trading Tower, Guangzhou 999077, Guangdong, with commercial registration in Hong Kong. The supplier carries an 'imported' tier designation and 'harbor' trust level, indicating marketplace onboarding without extensive verification documentation. No response rate data is available (0.00% recorded, zero average response hours), which signals limited or no engagement through the platform's inquiry system. The address structure, a trading tower branch office rather than production facility, suggests this entity functions as a trading company or commercial representative rather than primary manufacturer.

The listing does not disclose manufacturing capacity, workforce size, annual turnover, or specific clientele. No certifications are independently confirmed on the profile, despite the source description's reference to ISO and SGS standards (these appear in marketing material rather than verified credentials). Buyers should treat such claims as unverified until documentation is provided directly. The geographic positioning, Guangzhou within China's Pearl River Delta, places the supplier near major feather processing clusters in Guangdong and Guangxi provinces, though actual processing location requires confirmation.
