Frequently asked questions
- What is the reshoring readiness score for carbon products and insulators? 37.6 of 100 as of the latest month, a building case. The score combines tariff pressure (43/100), import dependence (53/100), and sourcing concentration (10/100) under the published RRI v1.0.0 methodology.
- Why does carbon products and insulators score this way? Importers currently pay a 15.25% effective tariff in this family, U.S. exports cover about 47% of what it imports, and its foreign sourcing measures 1020 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.
