What is the reshoring readiness score for abrasives and grinding wheels?

37.6 of 100 as of the latest month, a building case. The score combines tariff pressure (32/100), import dependence (72/100), and sourcing concentration (7/100) under the published RRI v2.0.0 methodology.

Why does abrasives and grinding wheels score this way?

The observed effective calculated-duty rate is 9.85% in this family, U.S. exports cover about 28% of what it imports, and its retained-source Herfindahl index is 720. Under this screening formula, a higher observed rate, deeper import dependence, and more concentrated sourcing raise the score; they do not establish plant-level profitability.

Does a high score mean reshoring is profitable?

No. The RRI is a screening indicator: it says the public trade data points that way, not that any specific plant pencils out. Validate with your own landed-cost, labor, and capacity numbers before deciding.

About this data

A transparent screening indicator built from public USITC trade data, not sourcing advice. The tariff term uses an observed effective calculated-duty rate, not an entry-specific legal rate or cash-paid amount. Concentration is matched to the month's calendar year (latest completed year for newer months); import dependence is currently a latest-year snapshot applied across the series and will deepen into a true history as export years accumulate. The named-top-sources HHI is a floor. Validate any decision with your own landed-cost and capacity numbers.
