STC Group, Down & Feather Testing


Consumer products that contain down and feather filled materials such as apparel, coats, jackets, bedding, pillows, etc. must be accurately labeled and advertised with the product’s filling contents. As the cost and quality differ greatly, manufactures, suppliers and retailers must be able to verify the accuracy of filling materials used and the amounts of down and feathers must not be misrepresented.
