Frozen marine products: specified packing materials and additive limits govern permitted imports and use for export compliance. Input-output norms under the Foreign Trade Policy specify permitted imported packing materials and processing additives for block-frozen marine products in polybags, with maximum weights per metric tonne and item-specific prohibitions; D7 is suspended. Applicants must ensure imported inputs match those actually used in the exported product, observing quantity limits (e.g., 5 kg for subitem (m), 3 kg elsewhere) and prohibitions (item 4 excluded for subitem (n); item 5 excluded for subitems (i), (j), (k), (l), (o)).
