Non-alloy steel forged hammers: specified allowable imported inputs, weighted handle materials, and FOB-linked percentage limits. Input-output norms prescribe allowable imported inputs and quantitative limits for non alloy steel forged hammers up to 10 kg: specified metal inputs, rust preventive chemicals limited to 2% of FOB, consumables limited to 4% of FOB, and detailed handle material alternatives with component weights for steel pipe plus rubber and nickel, wood, and polypropylene/fiberglass composites. Handle imports permitted by product nature and input allowances adjusted proportionately if handle weight differs from the 1 kg reference; applicants must ensure imports match inputs actually used in the exported product.
