US Tariffs in 2026: What Changed and Why It Matters

The US tariff landscape has undergone dramatic changes. What was once an average effective tariff rate of 2.5% has jumped to approximately 13.7% — the highest level since the Smoot-Hawley Tariff Act of 1930. Whether you are a business importing raw materials, an e-commerce seller sourcing products overseas, or a consumer wondering why prices keep rising, understanding how tariffs work in 2026 is essential.

Use our free US tariff calculator to instantly estimate the import duties and total landed cost for your goods. This guide explains the current tariff structure, how duty calculations work, and strategies for managing tariff costs.

The Current US Tariff Structure (March 2026)

US import tariffs in 2026 operate as a layered system where multiple tariff programs can apply simultaneously to the same goods. Here is the current structure:

Layer 1: Section 122 Global Tariff (10%)

Following the Supreme Court's February 2026 ruling that struck down IEEPA-based tariffs as unconstitutional, the administration reimposed a global import surcharge under Section 122 of the Trade Act of 1974. This 10% tariff applies to nearly all imported goods entering the United States, regardless of origin.

Section 122 authorizes the president to impose temporary tariffs of up to 15% for 150 days to address large and serious balance of payments deficits. The current rate is set at 10%.

Layer 2: Country-Specific Tariffs

On top of the base 10% tariff, additional duties apply based on the country of origin:

Country/RegionAdditional RateLegal BasisTotal with Section 122
China25%Section 30135%
Vietnam10%Reciprocal tariff20%
India, Thailand, Indonesia8%Reciprocal tariff18%
EU, Japan, South Korea, UK, Taiwan5%Reciprocal tariff15%
Australia3%FTA partner rate13%
Canada, Mexico (USMCA qualifying)0%USMCA10%

Layer 3: Section 232 — Steel and Aluminum (50%)

All steel and aluminum imports face a 50% tariff under Section 232 of the Trade Expansion Act, regardless of the country of origin. This rate was doubled from 25% on steel and 10% on aluminum in early 2025. The Section 232 tariff stacks on top of both the Section 122 base and any country-specific tariffs.

This means steel imported from China faces an effective tariff rate of 85% (10% + 25% + 50%), while steel from Canada faces 60% (10% + 0% + 50%).

Layer 4: Merchandise Processing Fee

The Merchandise Processing Fee (MPF) is a CBP fee of 0.3464% of the appraised value of imported goods, with a minimum of $31.67 and a maximum of $614.35 per entry. It applies to most commercial imports.

How to Calculate Your Total Import Duty

The formula for calculating total import duty is straightforward but involves stacking multiple layers:

  1. Determine your FOB value — the declared value of goods at the port of origin
  2. Add Section 122: FOB Value × 10%
  3. Add country-specific tariff: FOB Value × country rate (see table above)
  4. Add Section 232 if applicable: FOB Value × 50% (steel/aluminum only)
  5. Add MPF: (FOB + Shipping) × 0.3464%, clamped to $31.67–$614.35
  6. Sum all components = Total Duty

Your landed cost is the FOB value + shipping/insurance + total duty. This is the true cost of your imported goods.

Real-World Tariff Calculation Examples

Example: $10,000 of Electronics from China

ComponentRateAmount
Product Value (FOB)$10,000
Shipping & Insurance$500
Section 122 Global Tariff10%$1,000
Section 301 (China)25%$2,500
Section 232 (N/A)0%$0
Merchandise Processing Fee0.3464%$36.37
Total Duty35.4%$3,536.37
Landed Cost$14,036.37

That $10,000 purchase actually costs $14,036 once it clears customs. Our tariff calculator computes this instantly for any country and product type.

Example: $25,000 of Steel from Germany

Landed Cost$43,343.53

The Supreme Court Tariff Ruling: What It Means

On February 20, 2026, the US Supreme Court ruled that tariffs imposed under the International Emergency Economic Powers Act (IEEPA) were unconstitutional. The Court held that IEEPA, which was designed for financial sanctions and asset freezes, does not grant the president authority to impose import tariffs.

The administration responded by shifting the legal basis for tariffs to Section 122 of the Trade Act of 1974, which explicitly authorizes temporary import surcharges to address trade imbalances. While the legal foundation changed, the practical impact on importers was minimal — tariff rates remained similar, and the cost burden on businesses and consumers continues.

Strategies for Managing Tariff Costs

1. Diversify Your Supply Chain

Moving production from high-tariff countries (China at 35%) to lower-tariff alternatives can significantly reduce costs. Vietnam (20%), India (18%), and especially USMCA partners (10%) offer lower combined rates. However, factor in potential changes — tariff rates can shift quickly.

2. Leverage Free Trade Agreements

Goods that qualify under USMCA (Canada, Mexico) or other free trade agreements face reduced or zero country-specific tariffs. Ensure your products meet the rules of origin requirements to take advantage of these preferential rates.

3. Review Your HTS Classification

The specific Harmonized Tariff Schedule (HTS) code assigned to your goods determines the base duty rate. Some products may qualify for lower rates under different classifications. Work with a licensed customs broker to ensure your goods are classified correctly and favorably.

4. Consider Foreign Trade Zones

Foreign Trade Zones (FTZs) allow you to defer, reduce, or eliminate tariffs on imported goods that are stored, assembled, or manufactured within the zone. If you re-export goods or use imported components in US-manufactured products, FTZs can provide significant savings.

5. Price Accordingly

Use our tariff calculator alongside the markup calculator and profit margin calculator to ensure your pricing accounts for the true landed cost of goods. Many businesses underestimate tariff impact and erode their margins.

Frequently Asked Questions

What is the current US tariff rate in 2026?
The base US tariff rate in 2026 is a 10% global import surcharge under Section 122 of the Trade Act of 1974. Additional country-specific tariffs apply on top of this: China faces 25% extra (Section 301), India and Vietnam face 8-10% extra, and EU/Japan/UK face 5% extra. Steel and aluminum face a 50% tariff under Section 232. The average effective tariff rate across all imports is approximately 13.7%. Use our free tariff calculator to estimate your specific duty.
How do I calculate import duty on goods from China?
To calculate import duty on Chinese goods, add the following tariff layers: (1) 10% Section 122 global tariff, (2) 25% Section 301 China-specific tariff, (3) 50% Section 232 tariff if importing steel or aluminum, and (4) the Merchandise Processing Fee of 0.3464% of the CIF value. For general goods from China, the effective rate is approximately 35%. Use our tariff calculator for an instant estimate.
What is tariff stacking?
Tariff stacking means multiple tariff programs apply simultaneously to the same import, and the rates are added together. For example, steel from China faces 10% (Section 122) + 25% (Section 301) + 50% (Section 232) = 85% total tariff rate. The tariffs do not compound — they are calculated on the same base product value and then summed.
Are goods from Canada and Mexico tariff-free under USMCA?
Qualifying goods from Canada and Mexico can enter with reduced tariffs under the United States-Mexico-Canada Agreement (USMCA). However, the goods must meet strict rules of origin requirements — they must be manufactured or substantially transformed in North America using qualifying materials. The Section 122 base tariff of 10% may still apply to non-qualifying goods, and steel/aluminum face Section 232 tariffs regardless of origin.
What did the Supreme Court rule about tariffs in 2026?
In February 2026, the US Supreme Court ruled that tariffs imposed under the International Emergency Economic Powers Act (IEEPA) were unconstitutional because IEEPA does not grant tariff authority. The administration then reimposed tariffs under Section 122 of the Trade Act of 1974, which allows a temporary import surcharge of up to 15%. The current rate is set at 10%. This changed the legal basis but maintained similar tariff levels.
How much do 2026 tariffs cost the average household?
Economic estimates suggest the current tariff regime costs the average US household approximately $3,800 per year through higher prices on imported goods. The impact varies by spending patterns — households that buy more imported electronics, clothing, and automobiles feel a larger impact. Low-income households are disproportionately affected because they spend a larger share of income on goods subject to tariffs.
