USA is the world's premiere producer of tin capsules for wine and spirit bottles. We are leaders in the development of environmentally friendly production. Our capsules are produced with water-based paint which unlike solvent-based paint, do not pollute the air during production. Our production certifications include ISO 9000 and ISO 14001. Besides our sales and support staff, we also have a full-time technician to assist our customers with capsule application on their bottling lines. Our new office and warehouse are conveniently located near the Napa airport at 541 Technology Way.
