Code 3383 applies to employers engaged in manufacturing complete jewelry items such as rings,
earrings, necklaces, cuff links and bracelets. A sketch of the design is drawn on paper and a copper
or wax model is made. Rubber is wrapped around the model to form a permanent mold. Melted
wax is poured into the mold and allowed to cool and harden to the shape of the model. The wax
model is removed from the mold, secured to a plate and placed in a flask filled with plaster of Paris.
Once the plaster of Paris has hardened, the flask is placed in an oven to melt the wax model. The
melted wax is poured out and the mold is ready for use.

This classification includes manufacturing of products such as silver or silver-plated flat and
hollowware, picture frames, ornaments, and novelties made from silver or other metals like white
metal. Silver and white metal are received in sheet form, stamped or cut to size, spun, and
trimmed. Items may be plated using plating solutions, with finishing operations involving buffing and
polishing. This includes manufacturing automobile wheels made of metal and watch cases,
including wristwatch cases.

This classification also applies to the manufacturing of custom jewelry, exclusively designed as
one-of-a-kind pieces such as rings, pendants, and bracelets for individual clients. Mountings may
be created from photos or sketches, with no mass production involved. This includes precious
stone setting by hand and cutting or polishing.

This classification also applies to the manufacturing of watches, watch movements, and clocks.
Materials such as ferrous and non-ferrous alloys, fasteners, cases, gems, and watchbands are
received from others and used to make watches. The manufacturing process involves casting
metals, punching, blanking, turning, grinding, plating, and assembling watches and clocks using
hand tools or small machines. Precious gems may be drilled and set into watch faces. Items are
inspected, tested, and packed for shipment to customers. This includes the repair of watches,
principally performed for jewelry dealers.

In addition this classification also applies to manufacturing gold leaf and needles, medical
needles (hypodermic only), sewing needles and pen points.
