Container and seal verification required before gate pass; endorsement by Customs enables shipping bill registration and export clearance. Terminal procedures require that stuffed and self-sealed containers arrive with the invoice and shipping bill check list (including an examination report when stuffing was supervised). Gate passes must not be issued until the container has physically entered the parking plaza. The Customs Gate Officer must verify and endorse the container number, seal number and seal condition on the invoice or check list; this endorsement serves as proof for shipping bill registration and for granting the Let Export Order under the prescribed procedure.
