Global Tariffs Move Fast. Now You Can Too

The Fair Supply Tariff Calculator is designed to help businesses assess how newly imposed tariffs may affect the cost of goods and services across global supply chains. Using Fair Supply’s proprietary Integrated Assessment Engine, the calculator provides a before-and-after price comparison for goods and services impacted by tariffs introduced since 20 January 2025. Tariffs that were already in effect before this date are included in the “before” pricing benchmark.

By combining supply chain visibility with tariff data, the calculator helps companies anticipate cost increases, uncover hidden risks, and build more resilient procurement strategies.

A direct tariff is a duty imposed by a country on imported goods. The Fair Supply model assumes that these tariffs are fully passed on to the price of the affected goods.
Example: A 20% tariff on imported rice is assumed to raise the price of imported rice by 20%.

Indirect tariffs arise when price increases ripple through the supply chain due to tariffs on upstream inputs. Even if a good is not directly targeted by a tariff, the cost of its production may increase due to dependencies on tariff-affected components.
Example: A Japanese car might rely on U.S.-made electronic components, which in turn depend on tariff-affected imports from Canada. This chain reaction ultimately raises the cost of car production in Japan—even though Japan has not imposed or received any new direct tariffs.

This interconnected nature of modern supply chains means that most goods are impacted by multiple, indirect tariff effects, often across several tiers of suppliers.

Fair Supply’s Integrated Assessment Engine is built on a high-resolution global supply chain database. To model the impact of tariffs:

1) Tariffs are mapped to relevant transactions within the supply chain.

2) Price shocks are simulated across multi-tier global supply networks, capturing how cost increases propagate through supplier relationships.

3) Production cost increases are then estimated for each good or service, expressed as a percentage increase.

The final output reflects the total cost impact—both from upstream inputs (indirect tariffs) and final destination tariffs (direct tariffs on shipped goods).

To ensure clarity and consistency, the Fair Supply Tariff Calculator is based on the following assumptions:

Immediate price effect: The model focuses on short-term price shocks following tariff announcements. It does not assume immediate changes to supplier networks or trade routes.

Full price pass-through: Tariff costs are assumed to be fully reflected in final prices and not absorbed along the way.

Pre-existing tariffs are accounted for: All tariffs introduced on or before 20 January 2025 are assumed to be reflected in the underlying supply chain data and incorporated into the “before” price level.

Product-level assumptions: If a product category in Fair Supply’s taxonomy includes both tariff-affected and unaffected goods, the entire category is considered affected to ensure a conservative estimate.

Because of these assumptions, the Tariff Calculator provides a high-impact scenario to help businesses understand worst-case cost exposure from current tariffs. As global trade patterns shift and businesses adapt over time, future updates to the calculator will reflect structural changes in supply chains via Fair Supply’s evolving supply chain data engine.
