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

39.4 of 100 as of the latest month, a building case. The score combines tariff pressure (36/100), 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 9.55% 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.

Abrasives and grinding wheels: Reshoring Readiness

The Reshoring Readiness Index scores abrasives and grinding wheels at 39.4 of 100 (building case): a 9.55% observed effective calculated-duty rate, import dependence 72/100, sourcing concentration 7/100. Transparent methodology, monthly USITC data. Free.

The short answer

Abrasives and grinding wheels has an RRI of 39.4 of 100, a building case: the observed effective calculated-duty rate is 9.55% (tariff term 36/100), U.S. exports cover 28% of imports (dependence 72/100), and the named-source concentration floor is 720 HHI (7/100). The score is down 7.6 points over the past year.

The three terms behind the score

Tariff pressure 36/100 (45% weight): a 9.55% observed effective calculated-duty rate, level 32/100 with a one-year trend of 44/100.
Import dependence 72/100 (30% weight): U.S. exports cover about 28% of imports.
Sourcing concentration 7/100 (25% weight): 720 on the complete-board Herfindahl index.

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.
