4Tesla had deployed 36.0 gigawatt-hours of energy-storage products through the end of the third quarter of 2026.

The U.S. Foreign-Trade Zones Board authorized Tesla to conduct limited production activity at its facility in Brookshire, Texas, within subzone 84AM, after notifying the company on October 28 that the activity did not require further review. The decision was published on November 2 and covers the activity described by the company in its notice, rather than granting foreign-trade-zone status to the factory as a whole. The Board limited the authorization to a period of fourteen months. The decision permits production under the zone framework for the foreign materials and finished products specified in the notice and authorized by the Board. The move places the company’s energy-storage facility near Houston within trade arrangements that include special rules for covered inputs and products.

The scope of the authorization remains tied to the list of materials, components and products in Tesla’s notice, as the Commerce Department explains that production activity in foreign-trade zones does not automatically extend to other materials or products. The proposed inputs included battery cells, cooling pumps, power converters, printed circuit boards and neodymium magnets. Proposed finished products include Megapacks and Bento inverters, with ordinary tariff rates ranging from duty-free to 3.4%, according to the preliminary notice published in June. Listing these products does not mean that all their components are exempt from tariffs or that a single rate applies to them. The notice identifies the materials and products that may be covered by the authorized activity, while customs treatment remains linked to the type of material and its country of origin.

The decision’s rules state that materials subject to tariffs under Sections 122, 232 or 301 must enter the foreign-trade zone in privileged foreign status, with application varying by country of origin. This places a clear constraint on how certain inputs used in production, including materials sourced from abroad, are handled. The preliminary notice opened a public comment period through July 20, 2026, before the company was later notified that the Board saw no need for further review. In its third-quarter report, Tesla said its new factory near Houston began production during the quarter. It added that it continues to ramp up production of energy-storage products and capacity to meet high levels of demand.

The authorization comes as Tesla expands its energy-storage business; the company said it had deployed 36.0 gigawatt-hours of storage products through the end of the third quarter of 2026. It also reported that during the quarter it shipped its first Megapack using lithium iron phosphate cells manufactured at Gigafactory Nevada, describing the step as further progress in its efforts to localize supply chains. In its report, the company said the ultimate scope of recently announced trade-policy changes and how they will be applied remain uncertain. It warned that tariffs on imports, and any retaliatory tariffs that may follow, could affect consumer spending and demand for durable goods and related services. In the market, Tesla shares closed at $403.82 on November 2, compared with a close of $399.81 on October 30, without establishing that the decision caused the move.

On quarterly results, Tesla said revenue in the three months ended September 30 fell $49 million from the same period a year earlier. Net income attributable to common shareholders declined $586 million year over year to $787 million for the quarter. These figures provide financial context for the decision as the company expands its storage business, but do not by themselves determine the authorization’s effect on production costs or future results. Tesla said trade-policy changes could affect demand, while the scope of those changes and their final application remain unclear. This uncertainty continues to accompany the new factory’s operations, which began production during the third quarter, amid trade conditions that may change depending on the rules and country of origin.
