Sampling at place of dispatch limited to selective surprise checks; export sampling follows customs guidelines and AR-4 follows self-removal procedure. Paragraph 7 of the earlier circular on port/place examination is omitted; the Customs Wing circular governs examination of goods cleared on self-certification. Central Excise may draw samples at the place of dispatch only during selective or surprise checks as prescribed; sampling at the place of export follows Customs guidelines. Any conflict with mandatory per-consignment sampling or operational difficulty must be reported to the Board. AR-4 signing and disposal in self-certification cases will follow the self-removal procedure under the specified prior circulars.
