Rumors that Amazon would display the extra costs of goods with tariffs have been debunked. However, a few developers have offered an alternative with Chrome extensions. These new extensions take the proposed US tariff rates and display additional product costs across many online retailers.

While Amazon has stated that it will not display the additional cost of goods due to imposed tariffs, cost-conscious users still have options for conveniently displaying the estimated cost of tariffs while online shopping. Thanks to a handful of Google Chrome extensions, these new extensions utilize US government-provided tariff rate information to calculate and update the pricing of user-selected items. Currently, there are three extensions, and they all take slightly different approaches to estimating and displaying the updated prices.

The extensions "Tariff Price Adjuster" and "Tariff Shopping List" feature a drop-down menu to help users calculate the additional cost. In the menu, users can select the country of origin, product type, and either gross sum or percentage as the pricing model. For "Tariff Price Adjuster," the updated price will appear on the website itself, while "Tariff Shopping List" will create a running list that users can reference to see the additional costs associated with the product's respective tariff.

For users wanting a more straightforward approach, the "Tariff Lens" extension will automatically select the country of origin and, in theory, only apply the tariff calculation to affected items. Having just been updated to version 1.0.4, the "Tariff Lens" extension also claims several notable features, such as:

  • Improved detection of product origin
  • Enhanced product page detection
  • Anti-detection measures for site compatibility
  • Reduced loading times

However, of the currently offered extensions, "Tariff Lens" takes a more opinionated approach for displaying the updated prices. While the extension is well-intentioned when it comes to informing the consumer, time will tell if it will follow the fourth and now unavailable extension "Add the Trump Tariff", which was removed due to not meeting best practices for Chrome Extensions. Curious users can find a link to the extensions below. It should also be mentioned that these extensions do not function well together; therefore, flip-flopping between them is not ideal.
