Standard Input-Output Norms amended: additions and substitutions to Handbook Vol.2 affecting import-entitlement rules and wastage formulas for exporters. The Director General of Foreign Trade amends the Handbook of Procedures, Vol.2 by substituting, deleting and adding Standard Input Output Norms across product sectors (Chemicals, Engineering, Food, Plastics, Textiles, Handicrafts, Leather, Miscellaneous). New SION entries and detailed input lists (including wastage and conversion rules) are introduced, notably a comprehensive formula and entitlement rules for printed flexible packaging material (H404). Certain norms' validity is extended to 30 June 1999; exporters must follow prescribed procedures for regularisation thereafter.
