Question 1

What tariffs remain in effect after the SCOTUS IEEPA ruling?

Accepted Answer

After the February 20, 2026 Supreme Court ruling striking down IEEPA tariffs, the following tariffs remain in effect: Section 232 tariffs on steel (25%), aluminum (25%), automobiles (25%), semiconductors, copper (50%), and lumber (10%); Section 301 tariffs on Chinese goods (7.5-100% depending on product); and the new Section 122 temporary import surcharge effective February 24, 2026. All IEEPA reciprocal tariffs and IEEPA fentanyl tariffs have been vacated.

Question 2

How do I estimate my IEEPA tariff refund?

Accepted Answer

To estimate your IEEPA tariff refund, enter your HTS code, country of origin, and declared value into TADA's tariff calculator. The tool calculates the IEEPA duties you paid based on historical rates and estimates your potential recovery amount. The Supreme Court ruling means $142 billion or more in IEEPA duties collected during 2025 may be refundable to importers who paid them.

Question 3

What is the Section 122 temporary import surcharge?

Accepted Answer

The Section 122 temporary import surcharge is a new tariff enacted on February 24, 2026, following the SCOTUS ruling that struck down IEEPA tariffs. It replaces some of the revenue lost from the vacated IEEPA tariffs. The surcharge applies to imports from most countries and is subject to specific exemptions for goods already covered by Section 232 tariffs.

Question 4

How does TADA's tariff calculator work?

Accepted Answer

TADA's tariff calculator uses data from the USITC Harmonized Tariff Schedule and Federal Register to estimate import duties. Enter an HTS code (or search by product name), select a country of origin, and input your declared value. The calculator shows general duty rates, IEEPA rates (historical), Section 232 and 301 rates, and reciprocal tariff surcharges. It also estimates potential IEEPA recovery amounts following the Supreme Court ruling.

Question 5

What is the difference between TADA's free tariff estimator and Tariff Manager?

Accepted Answer

TADA's free tariff estimator provides quick HTS code lookup, single-part and multi-part duty estimates, and IEEPA recovery calculations. Tariff Manager is the enterprise platform that adds SKU-level risk assessment across your entire portfolio, true landed cost modeling with freight and surcharges, supplier-swap scenario planning, real-time tariff change alerts, and integration with procurement systems. Companies typically start with the free estimator and upgrade to Tariff Manager for portfolio-wide analysis.

Question 6

Can I analyze tariffs for multiple parts at once?

Accepted Answer

Yes. TADA's tariff estimator supports three modes: Quick Lookup for single HTS codes, Multi-Part Analysis for entering multiple parts manually, and File Upload for bulk analysis by uploading a spreadsheet with your part numbers, HTS codes, countries, and values. The tool calculates tariff exposure across your entire portfolio and identifies the highest-risk items.

Question 7

What HTS codes does TADA's calculator cover?

Accepted Answer

TADA's tariff calculator covers all 11,000+ HTS codes in the US Harmonized Tariff Schedule across 99 chapters. You can search by HTS code number or by product name to find the correct tariff classification. The tool includes general duty rates, special program rates (such as USMCA), and all additional tariff layers including Section 232, Section 301, and historical IEEPA rates.

Question 8

How often are tariff rates updated in TADA's calculator?

Accepted Answer

TADA aims to update tariff rates within 24 hours of published Federal Register changes or executive orders. Major policy changes such as the February 2026 SCOTUS ruling and Section 122 surcharge are reflected as quickly as possible. Rates are sourced from the US International Trade Commission (USITC) and US Customs and Border Protection (CBP) published schedules.

Question 10

How do Section 232 tariffs stack with other tariffs?

Accepted Answer

Section 232 tariffs apply on top of general duty rates but have specific stacking rules. Steel and aluminum face 25% Section 232 duties. Automobiles and auto parts face 25% Section 232 duties that do not stack on top of other Section 232 tariffs or Section 122 tariffs. Copper faces 50% Section 232 duties. Semiconductors face Section 232 duties effective January 15, 2026. TADA's calculator automatically applies the correct stacking rules for each product and country combination.

Question 11

The calculator automatically applies the correct combination of tariff layers for each country.
