Input-output norms for jute bags with plastic liners require imported inputs to match declared proportions used in exports. The SION for jute bags with HDPE/LDPE liners is suspended and specifies that HDPE/LDPE granules are required at 1.05 kg per kg of material content of the export product. Applicants must determine and document input proportions and ensure imported inputs correspond to those actually used in the exported goods.
