Compliance & Regulations
The Post-Clearance Audit (PCA) is a compliance verification process conducted by the Bureau of Customs after goods have been released from customs custody. It is designed to ensure that importers have correctly declared the value, classification, and other details of their shipments, and that the correct duties and taxes were paid.
Legal Basis
The PCA is authorized under the Customs Modernization and Tariff Act (CMTA), which empowers the Bureau of Customs to audit importers' records for up to three years from the date of final payment of duties and taxes.
Who Is Subject to PCA?
All importers are potentially subject to post-clearance audit, including:
- Regular importers with recurring shipments
- Non-Regular Importers (NRI)
- Companies that have availed of preferential tariff rates under Free Trade Agreements
What the Audit Covers
During a PCA, customs auditors review:
- Goods declarations and supporting documents
- Accuracy of declared customs values
- Correctness of tariff classification (HS Code)
- Completeness of import documentation
- Compliance with permit and regulatory requirements
- Consistency between financial records and customs declarations
What to Prepare
Importers should maintain the following records for at least three years:
- Commercial invoices and packing lists
- Bills of lading or airway bills
- Goods declarations (import entries)
- Import permits and regulatory clearances
- Payment records for duties and taxes
- Accounting and financial records related to importations
Possible Outcomes
- No findings – Audit closed with no deficiency
- Deficiency assessment – Additional duties and taxes are demanded, with surcharges and interest
- Penalties – Administrative fines for violations discovered during audit
- Referral for legal action – In cases of serious violations such as fraud or deliberate misdeclaration
How to Prepare for a PCA
- Maintain complete and organized import records from the start
- Ensure consistency between shipping documents and customs declarations
- Reconcile importation records with accounting entries regularly
- Respond promptly and cooperate with BOC auditors
- Engage a customs broker or trade compliance advisor for pre-audit review
A Post-Clearance Audit is not something to fear if proper compliance practices are in place. The best protection against adverse audit findings is accurate documentation, consistent record-keeping, and working with experienced customs professionals from the very beginning of each importation.
