Security Hold
Financial guarantees collected by customs authorities secure potential tariff liabilities prior to final administrative determination. Provisional duty deposits operate as cash payments or bonds required from importers of record when trade authorities issue preliminary affirmative determinations in dumping or subsidy investigations. Customs agencies hold these funds while investigating authorities calculate definitive dumping margins or countervailing subsidy rates.
Monthly import entry filings capture cumulative deposit amounts, whereas individual entry summaries record specific transaction assessments. National customs databases monitor compliance and enforce bonding limits across all active entry ports.
Assessment Margin
Importers adjust working capital reserves to absorb compulsory cash outlays during active trade remedy disputes. High duty deposits increase landed costs and reduce cash liquidity for importing enterprises. Commercial buyers often shift supply sourcing toward non-subject countries to maintain operating margins during multi-year investigation periods.
Refund Liquidation
Final liquidation decisions by customs authorities determine the permanent retention or refund of deposited cash collateral. Subsequent administrative reviews recalculate actual subsidy rates or dumping margins, generating cash refunds with interest when final rates fall below provisional assessments. Higher final rates require importers to pay supplemental duties plus accrued interest.
Duty deposits remain subject to retroactivity provisions when critical circumstances are formally determined.
