General Tariff Questions
What are tariffs and why do they matter?
Tariffs are taxes imposed on imported goods. They increase the cost of foreign products, affecting both businesses that import goods and consumers who buy them. Understanding tariffs helps you calculate true costs and make informed purchasing decisions.
What's the difference between tariffs and duties?
Tariffs and duties are often used interchangeably. Both refer to taxes on imports. 'Tariff' typically refers to the tax rate or schedule, while 'duty' refers to the actual tax amount paid. Our calculator handles both automatically.
How accurate are the tariff rates in this calculator?
We update our rates regularly from official government sources including USITC, CBP, and USTR. However, rates can change, and you should verify critical calculations with a customs broker for official documentation.
Do I need to pay tariffs on personal purchases?
Yes, but there's usually a de minimis threshold. In the US, shipments valued under $800 are generally duty-free. However, this can vary by country and product type. Commercial imports always require duty payment regardless of value.
Using the Calculator
How do I find my product's HTS code?
Use our HTS search feature by entering keywords describing your product. You can also check your supplier's commercial invoice, or search the official HTS database. For complex products, consult a customs broker.
What's the difference between FOB and CIF values?
FOB (Free on Board) includes the product cost and delivery to the port of export. CIF (Cost, Insurance, and Freight) includes FOB plus shipping and insurance to your port. US customs typically uses FOB value for duty calculation.
Why do I get different rates for the same product from different countries?
Tariff rates vary based on trade relationships. Countries with Free Trade Agreements (like USMCA members) often have reduced or zero tariffs. Others may face additional tariffs like Section 301 on Chinese goods.
Can I save or export my calculations?
Yes! Use the Export button to download your calculations as CSV, PDF, or Excel files. This is helpful for record-keeping, cost analysis, or sharing with your accounting team.
Specific Tariff Programs
What are Section 301 tariffs?
Section 301 tariffs are additional duties on Chinese imports, implemented in 2018-2019. They add 7.5% to 25% on top of regular duties for specific products. Our calculator automatically includes these when you select China as the origin country.
What are Section 232 tariffs?
Section 232 tariffs target steel (25%) and aluminum (10%) imports for national security reasons. They apply to most countries with some exemptions. Our calculator detects metal products and applies these automatically.
How does USMCA (formerly NAFTA) affect tariffs?
USMCA eliminates most tariffs between US, Mexico, and Canada for qualifying products. However, products must meet rules of origin requirements. Our calculator shows potential USMCA benefits when applicable.
Are there any tariff exclusions available?
Yes, USTR grants exclusions for some products, especially for Section 301 tariffs. Check the official USTR exclusion database for your HTS code. Exclusions can provide significant savings but require applications and approvals.
Business & Cost Impact
How do tariffs affect my pricing strategy?
Tariffs increase your landed cost, affecting margins and competitiveness. Our calculator shows the total impact, helping you decide whether to absorb costs, raise prices, or find alternative suppliers. Most businesses pass 50-75% of tariff costs to customers.
Can I reduce tariff costs legally?
Yes! Consider: 1) Sourcing from FTA countries, 2) Using Foreign Trade Zones, 3) Tariff engineering (modifying products to qualify for lower rates), 4) Duty drawback programs, 5) First Sale valuation. Consult a customs expert for strategies.
How do tariffs impact cash flow?
Tariffs are due when goods clear customs, before you sell them. This can strain cash flow. Consider using customs bonds, payment plans, or factor duties into your working capital needs. Our calculator helps you plan for these costs.
Should I switch suppliers due to tariffs?
Use our country comparison tool to evaluate options. Consider total landed cost, quality, lead times, and reliability. Sometimes paying tariffs is better than switching. Factor in transition costs and relationship value.
Technical & API Questions
