Tesla's Megapack production authorization at three California sites came through after five months, and it lasts one year

The list runs to twenty items.

That is what Tesla told the Foreign-Trade Zones Board it wanted to bring into three California sites in foreign status, and the Board has now decided that no further review of the activity is warranted at this time. Fremont, Livermore and Lathrop sit inside Subzone 18G. The finished products named in the notification are inverters, Megapack storage batteries, and vehicle bi-directional static converters. The company filed on 11 February. The applicant was notified on 30 July.

The authorization is not open-ended. The Board says the production activity described in the notification was authorized on a limited basis, subject to the Foreign-Trade Zones Act and the Board's regulations including section 400.14, and further subject to a one-year time period.

The components

The materials and components Tesla listed are where the operation becomes legible.

They include lithium-ion battery modules, printed circuit board assemblies for both the inverter and the bi-directional static converter, transformer cores, heatsinks, pyrotechnic disconnects, inductor assemblies, aluminum electromagnetic shields, silicone gap pads, copper brackets, polyurethane pads, and steel fasteners and screws specified by size. The duty rate on that list ranges from duty-free to 6.20 percent. On the finished products it ranges from duty-free to 3.40 percent.

The privileged foreign status catch

The earlier notice carries the qualification that matters most, and it was published in March rather than this week.

Certain of the materials and components are subject to duties under section 122 of the Trade Act of 1974, section 232 of the Trade Expansion Act of 1962, or section 301 of the Trade Act of 1974, depending on country of origin. Where those apply, the decisions require the merchandise to be admitted to a foreign-trade zone in privileged foreign status under 19 CFR 146.41. That locks the classification and the rate at admission.

Neither notice gives a dollar value, a volume, or a headcount. Neither explains the one-year limit.

The document: Department of Commerce, Foreign-Trade Zones Board, docket B-23-2026, Foreign-Trade Zone (FTZ) 18; Authorization of Production Activity; Tesla, Inc.; (Battery Storage Products and Components); Fremont, Livermore, and Lathrop, California. FR Doc. 2026-15661, filed for public inspection at 08:45 on 31 July 2026, publication date 3 August 2026, signed by Elizabeth Whiteman, Executive Secretary, dated 30 July 2026. The raw text of the authorization notice was fetched from federalregister.gov and read in full here; no fetch-tool summary was relied on. Verified in that text: Tesla, Inc. submitted a notification of proposed production activity on 11 February 2026 for its facilities within Subzone 18G in Fremont, Livermore and Lathrop, California; the notification was processed in accordance with 15 CFR part 400 including notice in the Federal Register inviting public comment at 91 FR 10369, 3 March 2026; on 30 July 2026 the applicant was notified of the Board's decision that no further review of the activity is warranted at this time; and the production activity described in the notification was authorized on a limited basis, subject to the FTZ Act and the Board's regulations including section 400.14, and further subject to a one-year time period. The underlying notification notice was separately verified rather than assumed: a Federal Register API query returned exactly one matching document for the cited page, FR Doc. 2026-04189, published 3 March 2026 at 91 FR 10369, titled Foreign-Trade Zone (FTZ) 18, Notification of Proposed Production Activity; Tesla Inc; (Battery Storage Products and Components); Fremont, Livermore, and Lathrop, California, and its full text was fetched and read. Verified in that earlier notice: the notification conforming to 15 CFR 400.22 was received on 11 February 2026; under 15 CFR 400.14(b) production activity would be limited to the specific foreign-status materials and components and specific finished products described in the notification and subsequently authorized by the Board; the proposed finished products include inverters, Megapack storage batteries, and vehicle bi-directional static converters, with a duty rate range from duty-free to 3.40 percent; the proposed foreign-status materials and components include pyrotechnic disconnects, inductor assemblies, plastic insulative trays with inverters, plastic housing and brackets for pyrotechnic disconnects, plastic covers for touch safety from direct current, printed circuit board assemblies for inverter, aluminum covers for inverters, lithium-ion battery modules, aluminum covers for vehicle bi-directional static converters, heatsinks within vehicle bi-directional static converters, transformer cores within vehicle bi-directional static converters, plastic structural insulative trays within vehicle bi-directional static converters, steel fasteners longer than 9.5mm, steel screws with threads of a diameter of less than 6mm, electrical connector housings for vehicle bi-directional static converters to low voltage systems, flexible rectangular pads of polyurethane, aluminum electromagnetic shields for PCBA within vehicle bi-directional static converters, printed circuit board assemblies for vehicle bi-directional static converters, silicone gap pads, and copper brackets for static converters, with a duty rate range from duty-free to 6.20 percent; certain materials and components are subject to duties under section 122 of the Trade Act of 1974, section 232 of the Trade Expansion Act of 1962, or section 301 of the Trade Act of 1974, depending on the country of origin, and the applicable section 122, section 232 and section 301 decisions require subject merchandise to be admitted to foreign-trade zones in privileged foreign status under 19 CFR 146.41; the comment period closed on 13 April 2026; and the notification notice was signed by Elizabeth Whiteman, Executive Secretary, dated 26 February 2026. Neither notice states a dollar value, a production volume, a headcount, or a reason for the one-year limitation, and none is asserted below. Both documents are Foreign-Trade Zones Board notices and neither contains any allegation against any party..
