How US Import Tariffs Work
How US Import Tariffs Work
Tariffs are taxes on imported goods. A 10% tariff on a $10 item adds $1 of duty at the border — before freight, brokerage, or retail markup. Companies importing the goods pay the government; they may pass some or all of that cost to US customers and businesses.
This pillar guide ties together our calculators and niche deep dives so you can move from headline confusion to a dollar estimate.
Why Governments Use Tariffs
Supporters argue tariffs raise revenue, encourage domestic production, and pressure trading partners. Critics argue they raise consumer prices, disrupt supply chains, and invite retaliation. Your operational job is narrower: quantify exposure for the products you buy or sell.
The Core Formula
Estimated duty = customs value × tariff rate. Landed cost = customs value + duty + freight + insurance + fees. Start with the category tariff calculator or HTS-8 lookup.
HTS Codes in Plain English
The Harmonized Tariff Schedule assigns product codes. Broader chapters group similar goods; HTS-8 lines get specific. See how to find your HTS code.
Weighted Averages vs Your Shipment
Our dataset uses trade-weighted imposed averages by product set (vintage June 9, 2026). Perfect for planning; not a substitute for entry-by-entry classification. Metals chapters often run hot — see highest-tariff product categories.
Who Ultimately Pays
Legally, the importer. Economically, costs can be shared across foreign exporters, US importers, retailers, and households. Model that split with the pass-through calculator and read who pays import tariffs.
Consumer Prices
Toys, furniture, appliances, and apparel are visible categories. Use the household basket calculator and will tariffs raise consumer prices.
Business Workflow
- Identify SKUs and origins.
- Estimate with category or HTS tools.
- Build landed cost.
- Stress-test pricing.
- Confirm with a licensed broker when dollars are material.

Legal Whiplash in Brief
Authorities and court outcomes can change which statute supports a given tariff action. Operational teams should update rate assumptions after major rulings rather than assuming last quarter's entry summary still applies.
