Meaning
Post-clearance administrative audits frequently culminate in formal demands for unpaid or underpaid import tariffs. Governed by Article 62 of the Customs Law of the People’s Republic of China, a back duty assessment allows customs authorities to retroactively recover tax deficits identified during post-release inspections. Authorities initiate recovery within three years if the revenue loss stems from enterprise error or non-compliance.
The statutory recovery power stops applying after three years for unintentional errors, though intentional duty evasion subjects the offender to unlimited recovery windows under administrative penalty procedures.
Audit Trigger
Specialized audit divisions conduct post-clearance reviews of enterprise financial ledgers, import contracts, shipping records, and payment receipts. A back duty assessment arises when auditors uncover underreported transaction values, incorrect commodity codes, or unauthorized diversion of duty-free processing materials. Customs officials issue formal audit findings detailing the technical basis for recalculation.
Entities receive a designated period to present counter-evidence or technical explanations before final calculation.
Liability Computation
Recalculation includes unpaid base duties, import value-added taxes, and overdue fine surcharges calculated at a daily rate of 0.05 percent. Late payment penalties accrue automatically from the date of original duty short-landing or underpayment. Taxpayers must settle the assessed deficit within fifteen days of receiving the formal tax collection notice.
Failure to satisfy the demand results in administrative enforcement actions against corporate bank accounts.
Legal Protection
Appeals against assessment demands require full payment of disputed liabilities or provision of equivalent bank collateral. Importers submit reconsideration filings within thirty days. Judicial review remains available through administrative courts.
