Quality Control

Quality inspection department guards a pass of the production departments

  • We have acquired a deep understanding of the standards and requirements in various places over the country
  • The down feather shall be provided with seven test reports before delivery
  • Global tests: USA, EN, GB/FZ/QB, JIS, KS, AS, CNS, IDFB 
  • Full range: tests of down feather (filling power, content and species)
Every lot of down flows through our quality systems, all supported by the YF DOWN Quality system providing continual oversight and testing at seven levels:
  • Raw material inspected at the source
  • D&F pre-processing inspection
  • D&F sorting stage inspection
  • D&F washing inspection
  • D&F packaging inspection
  • D&F shipping inspection
  • Independent testing prior to ship
