Premises Based Audit (PBA) is a structured post-clearance audit mechanism under the Customs Act, 1962. It empowers Customs authorities to examine the records of importers and exporters to verify compliance with duty payment, classification, valuation, exemption benefits and export scheme conditions. Though PBA is not an investigation by itself, audit observations can lead to duty recovery under Section 28, penalties or issuance of Show Cause Notices under Section 124. Early legal preparation is therefore critical to control exposure and ensure a smooth audit closure.
