Duty drawback: foreign bank charges not to be deducted from FOB when within overall agency commission limit, subject to evidence. Duty drawback may be permitted on the FOB value without deducting foreign bank charges if such charges are documented; foreign bank charges and agency commission are to be treated within an overall 12.5% limit of FOB value, and if their combined amount exceeds that limit it must be deducted from FOB for granting drawback. Field formations should regularise short realisations based on documentary evidence and treat related show cause notices accordingly.
