Verification Protocol
Retrospective government examinations confirm whether customs declarations match supporting commercial records and trade laws. An import documentation audit evaluates entry filings, commercial invoices, bills of lading and origin declarations submitted to customs authorities over historical reporting periods. Customs auditors review paperwork to identify misclassified tariff codes, understated transaction values or improper preferential duty claims.
Verification activities apply strictly to entry records filed within statutory limitation windows, typically covering three to five years of historical trade activity.
Substantive Examination
Audit teams analyze corporate ledger entries against customs entry summaries to detect discrepancies in declared values. Executing an import documentation audit requires reviewing ocean freight invoices, packing lists, assists and licensing agreement fee payments. Auditors cross-reference bank payment receipts with commercial invoices to identify unrecorded additions to dutiable value.
Sampling protocols select specific entry numbers for detailed scrutiny of country of origin marks and exemption certificates. Importers must produce requested entry dossiers, transport documents and internal compliance policies within fixed administrative response windows.
Statutory Penalties
Discoveries of unpaid duties or incorrect declarations result in formal assessment notices demanding back duties, accrued interest and administrative fines. Voluntary self-disclosures submitted before audit notification significantly reduce civil penalty percentages. A completed import documentation audit establishes formal compliance ratings for ongoing border processing clearance.
