Social Welfare Surcharge on imports must be paid in cash; duty credit scrips cannot be used to discharge SWS. Levy and cash payment obligation of Social Welfare Surcharge on imported goods is affirmed, and its collection cannot be met by debit to export-oriented duty credit scrips. Duty credit scrips under the FTP are a mode of payment allowed for Basic and Additional Customs Duty but do not envisage debit of SWS; therefore SWS must be paid in cash for future imports, while past debits in scrips will be accepted and not recovered.
