US Customs Clearance Services: End-to-End Import Compliance, Tariff Mitigation & 4GL Supply Chain Solutions

A Single Entry Bond (SEB) is designed for importers who bring in goods infrequently (typically fewer than three times per year). It covers one specific shipment entry and its financial value is calculated based on the entered value of the merchandise plus all applicable duties, taxes, and fees. Conversely, a Continuous Customs Bond covers all entries made through any US port of entry for a full 12-month period. It is economically required for regular importers, starting at a minimum coverage of $50,000 (which supports up to $500,000 in annual duties and taxes). Continuous bonds also streamline ISF 10+2 filings for ocean imports.

US Customs and Border Protection (CBP) strictly enforces the ISF 10+2 mandate for ocean cargo. An ISF must be transmitted electronically at least 24 hours prior to the cargo being loaded onto the vessel at the foreign port of origin. Failure to file, late filings, or inaccurate data transmissions can result in CBP assessing liquidated damages of $5,000 per violation, up to a maximum of $10,000 per shipment. Furthermore, non-compliant shipments are subject to Mandatory Customs Hold at the US port of discharge, incurring severe demurrage, container storage, and exam fees.

While CBP controls customs entry, Partner Government Agencies—such as the FDA (Food & Drug Administration), EPA (Environmental Protection Agency), USDA (Department of Agriculture), and CPSC (Consumer Product Safety Commission)—have independent statutory authority to inspect, hold, or sample imported goods. If a shipment requires PGA review, entry release will be flagged as "PGA Hold" or "May Proceed Pending Inspection." Delays can range from 24 hours to several weeks if documentation (such as FDA registrations, pesticide filings, or phytosanitary certificates) is missing. G&B conducts pre-arrival document verification to ensure instant automated PGA clearances.

Importers can utilize several legal, regulatory-approved mechanisms to minimize tariff impacts under Section 301, 232, or 201:

• HTS Code Engineering: Re-evaluating product components to ensure the item is classified under the most accurate legal HTS heading that may carry lower duty rates.
• First Sale Valuation: Paying duty based on the manufacturer's initial sale price to an intermediate broker rather than the final invoice price to the US importer.
• Foreign Trade Zones (FTZ) & Bonded Warehouses: Deferring duty payments until merchandise enters US commerce, or avoiding duties entirely if re-exported.
• Duty Drawback: Claiming a 99% refund on duties paid for merchandise subsequently exported from the United States.

CBP uses automated risk-scoring to select containers for physical or non-intrusive inspection. Exam types include VACIS/X-Ray Exam (non-intrusive scanning), Tailgate Exam (opening container doors to visually inspect contents), Intensive/CET Exam (transferring cargo to a Centralized Examination Station for full devanning), and MET Exam (Merchandise Enforcement Team compliance check). Under US administrative law, the importer of record is fully responsible for all exam costs, drayage transfers, station handling fees, and any container storage fees incurred during the inspection window.

To execute a compliant entry submission, the importer must provide five core documents to the customs broker prior to vessel/flight arrival: (1) Commercial Invoice stating harmonized descriptions, unit values, currency, and country of origin; (2) Packing List detailing gross/net weights and package counts; (3) Ocean Bill of Lading (B/L) or Air Waybill (AWB); (4) Customs Power of Attorney (POA) granting legal authority; and (5) Specific PGA documents where applicable (e.g., Toxic Substances Control Act (TSCA) statements, FDA product codes, or Certificates of Analysis).
