<h1>Input-output norms for 1500W/2000W halogen lamp manufacture require proportional component allocation and matching imported goods to export product</h1> Standard input-output norms for manufacture of 1500W/2000W halogen lamps (engineering products) specify component types and per-unit quantities-including fused quartz main and exhaust tubes, molybdenum ribbon and wire, platinum-clad moly ribbon, tungsten filament components, contacts, ceramic bases, cement, ink and krypton gas-and note the schedule is suspended by a public notice. The regime requires determination of proportional inputs for different resultant products and obliges applicants to ensure imported goods match those used or required in the listed export product.
