Content Analysis. Standard – EN 12131 (IDFB 3)

Down content refers to the proportion of down in the specific amount of feather & down filling material.

Down content is one of the most critical quality measurement indicators for feather & down raw materials and finished products.
Down content is also the critical factor that will influence the price in the feather & down trading.
Higher down content usually represents the better fill power performance and insulation ability of a down product.

According to The International Down and Feather Bureau (IDFB) the
definition for Down Cluster is a group of components including down,
nestling down, and plumules.

The percents of Down Clusters: The higher the number of clusters, the better the down (85% - 95%)

Amount of down and feather fibers (down fiber + feather fiber):
The fewer fibers, the better the down.

Duck and goose are types of waterfowl.
Geese are generally larger than ducks and they have longer neck (the way scientists differentiate between ducks and geese is based on how many bones they have in their necks) and longer legs compared to ducks.
Ducks are omnivores, geese are herbivores.

Goose down is generally much more expensive than duck down.
It has high fill power, insulation power, and minimal odor issues.
Goose down cluster is commonly larger and stronger than duck down.

Goose down has a higher value when compared to duck down.
Less duck down within goose down - more expensive down filler.

According to the USA 2000 Labeling standard, all goods products must contain 90 % goose down.

In European Labeling standard EN 12934, the amount of goose required
is a minimum of 90 % goose for labeling products us Pure Goose down, and 70% - 89,9% for labeling – Goose down.
