Down and Feather Testing
IDFL assists companies in the down and feather industry acquire
sterilization permits and meet customer quality expectations by inspecting factories and testing down and feather material. IDFL grades material quality by testing down and feather composition, content analysis, and

s primarily for CSR topics like live plucking. IDFL consults or performs audits under different licenses such as:
– IDFL internal standard, this standard began in 2008 and has gone through different revisions since. It has options of scope which allow tracing a particular leg, location or the whole of a supply chain.
– Traumpass standard, this is a German-based standard that translates as 'dream standard' and is developed by the German Down and Feather Association.
– Downpass standard, is a standard that is based all of European Union Directives. It contains a quality element verifying the quality of the material and in addition has the actual audit process tracing material from a product to the source of the raw materials. This standard is strongest in Europe, and countries with higher European influence but is gaining traction in other North American markets.
– RDS (Responsible Down Standard) This standard was developed with many discussions in the OIA (Outdoor Industry Association), but was then completed by The North Face and then strategically gifted to the Textile Exchange The RDS standard has claimed to save
– TDS (Traceable Down Standard), This standard was developed by Patagonia to address needs in their supply chain and was also gifted to NSF (National Safety Foundation). It was also seen as a way for Patagonia to not be outdone by competitor TNF
Audit services typically consist of tracing material from a finished good back to the original sources through different means. Either through invoices or through an audit system that tracks the chain of custody and will include visiting supply chains and factories to verify down and feather material is not originating from live plucking, Foie Gras production and also can inspect other elements such as sterilization procedures.
A new element that is being considered to support the traceability audits is isotope technology which IDFL also provides.
