How to Secure Transactional Compliance before a Deal Closes

A defensible trade compliance program includes tariff classification, country-of-origin documentation, restricted-party screening, export-control compliance, and internal audit procedures. Classification errors are the most common enforcement trigger, so your program should assign responsibility for tariff coding to trained personnel and document the reasoning behind each classification decision. Country-of-origin rules require you to track the source of materials and manufacturing steps; marking errors or misstatements on invoices and packing lists invite CBP challenges. Restricted-party screening means checking customer and supplier names against the Office of Foreign Assets Control (OFAC) sanctions list, the Entity List, and the Denied Parties List before each transaction. Internal audits and record-keeping protocols create evidence that your company took reasonable steps to comply, which can mitigate penalties if an error is discovered.

Tariff classification determines the duty rate, quota applicability, and whether a product is prohibited or restricted. CBP can challenge your company's prior declarations during a post-entry audit or at the time of import. If CBP reclassifies your goods to a higher-duty code, you owe back duties, interest, and potential penalties. To protect your position, document the physical characteristics and functionality of your goods, consult with a tariff specialist if classification is uncertain, and maintain that documentation for at least five years. If CBP issues a notice of liquidation or re-liquidation with a different classification, you have limited time to file a protest or request a ruling review; missing that deadline forecloses your appeal rights.

U.S. Customs and Border Protection (CBP), the Commerce Department's Bureau of Industry and Security (BIS), and the Treasury Department's Office of Foreign Assets Control (OFAC) are the primary enforcers. CBP administers tariff law, country-of-origin rules, and import/export documentation; it can examine shipments, issue seizure notices, and assess civil penalties or criminal charges for smuggling or fraud. BIS regulates exports of controlled commodities and technologies under the Export Administration Regulations (EAR); violations can result in denial of export privileges and substantial fines. OFAC enforces sanctions programs; transacting with a sanctioned person or entity can trigger civil penalties and potential criminal prosecution for willful violations. Each agency has its own notice procedures, penalty schedules, and appeal forums. CBP penalties are challenged through the Court of International Trade; BIS violations are reviewed by Commerce; OFAC cases may proceed through administrative process or federal court.

Preserve all commercial invoices, bills of lading, packing lists, certificates of origin, supplier declarations, tariff classification worksheets, and any communications with freight forwarders or customs brokers for at least five years from the date of import or export. If CBP opens an audit, you will need to produce the original entry documents, proof of payment, and contemporaneous business records showing how classification decisions were made. Delayed or incomplete submission of loss affidavits or protest documentation to CBP can result in forfeiture of your right to challenge a liquidation decision. Establish a centralized document management system so you can retrieve records quickly; if you cannot produce documents within CBP's specified timeframe, your ability to contest penalties weakens significantly.

Misclassification is the most frequent violation and can result in CBP re-liquidating the entry and assessing back duties, interest, and a penalty of up to 20 percent of the appraised value for negligence or up to 40 percent for gross negligence or fraud. CBP may discover the error during a post-entry audit or if a competitor files a protest alleging your company's classification is wrong. If you receive a notice of re-liquidation or a penalty notice, you have limited time to file a protest with CBP or seek a ruling from the Customs Rulings Online Search System (CROSS). Mitigation depends on whether the error was unintentional and whether your company took reasonable steps to classify correctly. If you can show that you relied on a prior CBP ruling, consulted a tariff specialist, or had a good-faith dispute about product characteristics, you may persuade CBP to reduce or waive the penalty.

OFAC maintains multiple sanctions lists targeting individuals, entities, and vessels in countries subject to U.S. .mbargoes or targeted programs. Before importing from or exporting to any customer or supplier, your company must screen the name against the Specially Designated Nationals (SDN) list and other OFAC lists. A transaction with a sanctioned party is prohibited even if the counterparty is a subsidiary or agent; OFAC imposes liability on the U.S. .erson conducting the transaction. If your company discovers that a customer or supplier appears on an OFAC list after a transaction has begun, cease the transaction immediately, document the discovery, and consider filing a voluntary self-disclosure with OFAC. Voluntary disclosure can result in a significant penalty reduction; failure to disclose typically leads to civil penalties ranging from thousands to millions of dollars depending on transaction size and the company's compliance history. Maintain screening records and audit logs showing when and how you checked each party.

Your policy should assign responsibility for tariff classification, country-of-origin verification, restricted-party screening, and export-control compliance to specific personnel or departments. Define the process for classifying new products, including who consults tariff references, when external specialists are engaged, and how decisions are documented. Require that all import and export transactions include restricted-party screening before payment or shipment, with records retained. Establish a procedure for responding to CBP inquiries or audit notices, including who has authority to communicate with customs brokers or legal counsel. Include a mechanism for employees to report suspected violations without fear of retaliation. Document all training sessions and maintain attendance records; if an employee later claims ignorance of a compliance requirement, your training records demonstrate that the company provided instruction. The policy should also specify that the company will conduct periodic internal audits to identify misclassifications, missing documentation, or restricted-party matches before CBP or OFAC discovers them.

Audits typically begin with a written notice specifying the scope, time period, and documents requested. Respond promptly and completely; late or incomplete responses can lead to adverse inferences or expanded investigation scope. Designate a compliance officer or legal counsel to coordinate the response and ensure documents are organized chronologically and by transaction type. During the audit, CBP may examine your tariff classification methodology, country-of-origin determinations, and restricted-party screening procedures. If the audit identifies errors, consider whether they are systemic or isolated; systemic errors warrant a more substantial remediation plan and may justify a penalty-mitigation request. After the audit concludes, CBP typically issues a closing letter summarizing findings and any penalties assessed. If you disagree with CBP's conclusions, file a protest within the prescribed timeframe. Retaining a customs counsel early in an audit process improves outcomes because counsel can frame your company's compliance efforts favorably and identify legitimate defenses or penalty-mitigation arguments.

The Port of New York and New Jersey handles millions of containers annually, and CBP maintains rigorous examination protocols. One common procedural pitfall is delayed filing of entry documents or protest paperwork; CBP's deadlines are strict, and missing a filing window can forfeit your right to challenge a penalty or re-liquidation. If your company imports through New York and receives a notice of action from CBP, verify the deadline immediately and ensure your customs broker or attorney files any required response within the timeframe specified. Another risk is incomplete loss affidavits; if CBP denies a refund claim because your company's loss documentation was deficient or submitted late, the denial is difficult to overturn on appeal. Maintain a checklist of required documents for each transaction type and assign responsibility to someone who tracks filing deadlines.

For CBP disputes, the Court of International Trade (CIT) in New York provides judicial review of tariff classifications, penalty assessments, and liquidation decisions. The CIT is a specialized federal court with expertise in trade law, and filing a complaint there stays CBP's collection of penalties while the case proceeds. For OFAC violations, your company may request an administrative hearing or seek judicial review in federal court; voluntary disclosure remains the most effective mitigation strategy before enforcement action is initiated. The International Trade Commission (ITC) provides tariff rulings and can issue advisory opinions on classification questions. Many companies benefit from obtaining a binding Customs Ruling from CBP in advance of imports; if your company later imports goods consistent with the ruling and CBP challenges the classification, you can cite the ruling as a defense. Consider consulting with counsel experienced in import and trade compliance matters early, especially if your product line involves gray-area classifications or your customer base includes entities in sensitive geographies. Compliance counsel can also advise on US trade act compliance issues, including free-trade-agreement eligibility and anti-dumping duty exposure.
