Social Welfare Surcharge exemptions expanded to additional tariff headings with new schedule entries and specified exclusions. Amends the Customs notification on Social Welfare Surcharge exemptions by substituting the proviso to expand referenced serial identifiers, altering specific tariff lines in the Table (including a parenthetical exclusion and insertion of additional headings), and inserting new serial entries that define eligible headings while carving out items already covered under earlier schedule entries, thereby refining the scope of goods receiving SWS exemption under the notification.
