Try a modeled shipment before opening the full calculator

Pick a sample to see how base duty, user-entered additional tariffs, logistics, and landed cost fit together. Every sample is deliberately labeled as modeled so it does not masquerade as filing advice.

Samples are for product walkthrough only. Replace the fields with your shipment data and verify rates with official sources or a licensed broker.

Why a workspace

A number is useful. A number with sources is reviewable.

TariffsChart is designed for the step after a quick estimate: preserving the source URL, retrieval date, assumptions, and review status behind the number.

FAQ

Frequently asked questions

What to know before using TariffsChart for shipment planning.

Is TariffsChart an official customs database?

No. TariffsChart is a planning and recordkeeping workspace. We link out to official sources like USITC HTS, CBP CROSS, USTR Section 301 pages, AD/CVD notices, and IEEPA FAQ pages and preserve the URLs + retrieval dates you cite, but we never replace a licensed customs broker or a binding CBP ruling. Every estimate is clearly labeled as planning-only.

What is the current US tariff on imports from China?

There is no single China tariff rate. For planning, China-origin imports usually start with the MFN base duty, then require a Section 301 list check, a Section 122 status check when applicable, and product-specific Section 232, AD/CVD, quota, and Chapter 99 review. Many consumer-goods scenarios land in the 7.5%–25% additional-duty range before product-specific remedies, but the exact rate must be verified by HTS code and official source.

Does Section 122 still apply after the May 2026 ruling?

Treat Section 122 as a separate legal-status item that needs current source review. TariffsChart models it as a 10% planning layer only when the official source chain supports that assumption; it should not be merged into the base HTS duty. Before relying on it, check Federal Register notices, CBP CSMS messages, court status, and broker guidance.

How do Section 301 and Section 232 tariffs stack?

Section 301 and Section 232 are separate additional-duty authorities. Section 301 is commonly China-origin/list-based, while Section 232 is product and national-security based for categories such as steel, aluminum, autos, and related products. A landed-cost model may need MFN base duty plus each applicable additional layer, but exclusions, quotas, Chapter 99 instructions, and effective dates can change the result.

Is USMCA still in effect for Mexico and Canada?

Yes. USMCA remains the preferential framework for qualifying Mexico-origin and Canada-origin goods. Qualifying entries can receive preferential treatment, while non-qualifying goods still need normal HTS, Section 122, Section 232, AD/CVD, quota, and broker review. Always document origin and USMCA eligibility before treating a shipment as duty-free.
