What is the reshoring readiness score for glass fiber and reinforcements?

25.6 of 100 as of the latest month, a weak case. The score combines tariff pressure (34/100), import dependence (23/100), and sourcing concentration (14/100) under the published RRI v1.0.0 methodology.

Why does glass fiber and reinforcements score this way?

Importers currently pay a 10.38% effective tariff in this family, U.S. exports cover about 77% of what it imports, and its foreign sourcing measures 1360 on the Herfindahl index. Higher tariffs, deeper import dependence, and more concentrated sourcing all strengthen the economic case to produce domestically.

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 is monthly; 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.
