Regulations

The rules the map answers

Each rule in one line, who it is for, and the map with that lens on.

Solar · Batteries

FEOC

A clean energy tax credit under §45X, §45Y or §48E is lost if the taxpayer is a prohibited foreign entity, or if too much of the project or the component comes from one.

More

A supplier counts as prohibited when it is owned or controlled from China, Russia, Iran or North Korea, directly or through ownership above a threshold, debt, board seats or licensing.

The map colors every solar and battery company by who owns it in the registries, and a full screen adds the government lists, so you can see where a chain is exposed before you file.

For: Anyone claiming §45X, §45Y or §48E credits, and the suppliers whose parts go into those projects.

Also on the battery map.

Chips

CHIPS and export controls

CHIPS Act funding comes with guardrails: no expansion in a country of concern and no joint research with an entity of concern, for ten years.

More

Export controls add their own lists: a company on the Entity List or the sanctions list needs a license most will not get, and some named chip makers are barred from federal procurement from late 2027.

The map colors every semiconductor company by those lists and by the same ownership test, so a fab, its suppliers and its tool makers can be checked at a glance.

For: CHIPS award recipients, their suppliers, and anyone selling into or buying from the chip supply chain under US export rules.

All sectors

Country of origin

Where a part is made decides tariffs, local-content credits and which rules apply, and the answer is a plant, not a head office.

More

The map places every company at its headquarters and lists the production places on its record, with the country of each.

Search a country on the map to read a chain by geography, and every company card names its country.

For: Buyers filing domestic-content or tariff paperwork in any of the three sectors.

Also on batteries and chips.

A rule that is not here yet is a conversation: say which one when you write to us.
