Customs duty and import duty refer to taxes placed on imported goods by the United States government. These duties are based on a commodity's classification under the harmonized tariff schedule (HTS code), its declared value, and its country of origin . The distinction between import tax and sales tax is also crucial. Import tax is paid at the border and calculated as a percentage of the goods' value, whereas sales tax is collected at the point of sale within the United States.

The role of US Customs and Border Protection: This federal agency enforces the collection of customs duties US , investigates errors, and manages border security for international trade. How Are Duty Rates Determined? Understanding the Tariff Schedule Duty rates in the United States are primarily determined by consulting the Harmonized Tariff Schedule (HTS), a highly detailed product classification system. Each import is assigned an HTS code reflecting its nature and intended use, which in turn determines its applicable duty rate . This comprehensive tariff schedule is regularly updated, incorporating everything from electronics and textiles to chemicals and food. The country of origin and the correct assignment of the HTS code affect your import duty . Trade agreements—like NAFTA, USMCA, or GSP—can reduce or eliminate duties for qualifying goods. It’s crucial to use the most current tariff schedule from the official gov website and confirm the product’s journey matches United States rules for origin documentation.

First, you must submit an entry package including your customs entry, the commercial invoice, and a detailed packing list. These documents should match your HTS code and accurately reflect the country of origin , quantities, and value of the goods. Your customs broker plays a crucial role in this process. They prepare necessary declarations and correspond with Customs and Border Protection (CBP) on your behalf, helping you avoid errors that could trigger further scrutiny or penalties. When you interact with CBP officials, transparency is key. Ensure you provide all requested documentation and clarify any ambiguities proactively—mistakes in customs clearance may delay your shipment or increase your financial obligation. Essential Documents: Customs entry, commercial invoice, packing list (must match HTS code and values declared) Importance of Customs Brokers: Most importers benefit from using a licensed broker knowledgeable in tariff schedules, free trade agreement eligibility, and duty rates Interacting with CBP: Provide accurate, up-to-date information—honesty prevents costly delays or penalties Common Mistakes that Trigger Additional Customs Duties and Delays One of the most expensive mistakes US importers make is improper classification using the harmonized tariff code (HTS code). Assigning the wrong code results in either overpaying or facing penalties after audits reveal discrepancies. Even minor clerical errors can trigger unnecessary customs duties and substantial delays at the border. Another frequent pitfall is failing to verify the country of origin —particularly important for goods eligible for reduced rates under a free trade agreement. Inaccurate declarations or missing documentation can void your eligibility and lead to retroactive duty collection at higher rates. Also, correctly declaring your goods’ value and using the appropriate duty rate is non-negotiable; mistakes in valuation can result in interest charges and additional customs fees. Improper classification under the harmonized tariff code (HTS code) Neglecting to double-check the country of origin (essential for free trade and lower duty rates) Errors when declaring imported goods’ value or applying the wrong duty rate "A single mistake in your customs declaration can lead to significant penalties or increased duty rates." Leveraging Trade Agreements to Reduce Import Duties US How Free Trade Agreements and Other Trade Agreements Impact Duty Rates Free trade agreements (FTAs) and other trade agreements are powerful tools for reducing your import duty and customs duties US . The United States has negotiated several agreements that allow for reduced or even zero tariff rates on imports that meet strict eligibility criteria. Using these agreements, such as USMCA (formerly NAFTA), CAFTA-DR, or the Generalized System of Preferences (GSP), requires detailed knowledge of the correct tariff schedule and compliant documentation. Each trade agreement comes with its own set of rules regarding product eligibility, required certifications, and proof of country of origin . Staying updated via official government agencies or a licensed customs broker is crucial, as failure to comply can mean retroactive duty charges or loss of preferential rates. Major Free Trade Agreements Impact on Import Duty and Customs Duties Agreement Eligible Countries Products Covered Potential Duty Savings Required Documentation USMCA US, Mexico, Canada Automotive, Agriculture, Textiles, etc. 0-100% Reduction Certificate of Origin GSP Developing Nations (varies) Many industrial and consumer goods Up to 100% Origin Statement CAFTA-DR Central America, DR Textiles, Food, Industrial Goods 0-85% Manufacturer's Affidavit Applying for Duty-Free Status and Managing Country of Origin Rules Securing duty-free status under a free trade agreement is not automatic. You must provide all required documentation, such as certificates of origin or detailed manufacturing affidavits, proving your goods meet the agreement criteria. Meticulous record-keeping is critical—officials will audit eligibility periodically, and improper documentation can result in large, retroactive import duty assessments. The country of origin rules are especially significant for products sourced or processed in multiple locations. Goods not meeting the substantial transformation or value-added thresholds won’t qualify for special rates, even if partially manufactured in an eligible country. Consulting the latest guidance from the Customs and Border Protection or working with an experienced customs broker ensures you don’t miss these important details.

Next, confirm the product's country of origin , which affects eligibility for reduced rates under a relevant trade agreement .

Import tax can be substantial, so always verify your cost structure using official sources and review your numbers for accuracy before submitting customs entry documents.
