US import duty calculators: Temu, Shein, AliExpress tariffs

ImportDutyUSA is a free, independent reference site launched after the suspension of the $800 de-minimis exemption on 29 August 2025. It provides standalone calculators for Temu, Shein, and AliExpress orders to estimate landed costs before purchase. The tools factor in the Section 301 forced-labor duty, regular duty rates, and courier brokerage fees without requiring a login or account creation.

The site is published and maintained by an independent solo publisher based in Spain who operates a portfolio of free, single-purpose consumer web tools. There is no company behind the site, no sales team, and no login required to use the calculators. The tools are designed to help US consumers see the real landed cost of foreign-site orders before they click buy.

The platform offers five standalone single-purpose calculators including an HTS Code Duty Rate US Lookup, a Temu Shein Tariff Impact Checker, and a US Returning-Traveler Duty Exemption Checker. Each tool cites the specific rule with a verification date and is designed to be a single-purpose calculator that does not require user registration. The calculators estimate the duty rate, tariff stack, and full landed cost before payment.

All five calculators are completely free with no paywall, no account, and no login required to access the tools. The site uses cookieless analytics so that user-entered order details stay in the browser and never leave the device. There is no subscription fee or hidden cost to use the estimation tools.

The calculators specifically estimate duties for goods from the 60 economies USTR investigated under Section 301, including the 12.5% forced-labor duty that replaced the expired Section 122 surcharge on 24 July 2026. They also account for the regular duty rates for apparel, electronics, and shoes, as well as the Section 301/232 add-ons and courier brokerage fees. The tools factor in the elimination of the $800 de-minimis exemption which has been suspended since 29 August 2025.

The site is located in Spain and serves US consumers who shop on international marketplaces like Temu, Shein, and AliExpress. It is not affiliated with, endorsed by, or connected to US Customs and Border Protection, USTR, USITC, or any specific marketplace. The calculators are designed for anyone needing to know the real landed cost of a foreign-site order before purchase.

The calculators include a US Gift vs Commercial Import Duty Checker to determine if a package qualifies as a duty-free bona fide gift under $100 per recipient per day. Another tool is the US Returning-Traveler Duty Exemption Checker which finds the exact duty-free personal exemption based on time abroad, origin, and recent use. These features help users distinguish between commercial imports and eligible gifts.

The site launched after the 29 August 2025 elimination of the $800 de-minimis exemption made every package shipped to a US address dutiable. It was created to help consumers see the real landed cost of a foreign-site order immediately after this rule change. The calculators now factor in the new tariff stack including Section 301 and regular duties.

The calculators estimate the duty rate, tariff stack, courier brokerage fees, and full landed cost before the user pays. They provide a comparison of flat-rate versus ad-valorem comparisons for China-origin goods entered since 24 July 2026. The tools also show the effective rate once tariffs stack, which can land at roughly 36-70% of merchandise value for apparel.

The calculators use declared value rather than retail value for duty calculations, as the entered value is often closer to wholesale. This is a legitimate practice where the platforms negotiate bulk-clearance arrangements but still pass the per-order duty to the consumer. The tools reflect how Temu and Shein now show import fees as a line item at checkout.

The calculators are designed to work without any login, account creation, or payment required from the user. They use cookieless analytics to ensure user-entered order details stay in the browser and are not tracked across sessions. The site explicitly states it does not require a login to access the tools.
