All finished products are subjected to a final QC (quality control) inspection. First the inspectors verify that all specified receiving and in-process inspections have been carried out satisfactorily, and then they perform the remaining inspections and tests necessary to complete the evidence that products conform to specified requirements. Only those products that pass the final inspection are admitted to the finished products store and can be shipped. Finished products are identified with a Nu Flow label and signed by the employee conducting the testing. Shipments are traced until our customers receive them. Special ordered products may cause delays in shipping schedules.
