SIC Code 3679-12 Description (6-Digit)

Crystal Quartz Manufacturing is a specialized industry that involves the production of quartz crystals that are used in a variety of electronic devices. These crystals are made from high-purity quartz and are used to provide precise timing signals in electronic circuits. The manufacturing process involves a range of steps, including cutting, grinding, and polishing the quartz crystals to the required size and shape. The crystals are then tested to ensure that they meet the required specifications before being packaged and shipped to customers.
