<h1>Foreign Trade Policy schedule sets input-output norms for suction valve (C1777); importers must match parts and determine input proportions</h1> A schedule under the Foreign Trade Policy sets input-output norms for a suction valve for compressors (item code C1777), listing constituent parts and permitted net-to-net quantities for each (valve plate, springs, plates, nuts, pins, washers, bolts, seat, guard, locking device, unloader, guide bush, actuator, etc.). The entry is marked as suspended by public notice. The rule requires importers to ensure that imported items match those used or required in the manufacture of the declared export product, and to determine proportions of inputs used across resultant products.
