Tesla's Megapack factory near Houston can now use foreign-trade-zone procedures for some of its production. That is according to a Federal Register notice published on Nov. 2.

What was approved

  • The Foreign-Trade Zones Board approved production activity for Tesla's battery storage products within FTZ 84 at Brookshire, Texas.
  • The board made the decision on Oct. 28.
  • The authorization is limited and runs for 14 months.

Why it matters

FTZ status lets a manufacturer delay, and sometimes reduce, customs duties on imported parts used in production. In its June notice, Tesla listed foreign components including battery cells and neodymium magnets. Tariffs on battery cells have become a major cost for U.S. energy storage makers.

The plant

Electrek reported in August that Megapack 3 production had started at the Texas site. The notice doesn't say how many units Tesla will build there.
