Translucent Solar, LLC submitted a notification of proposed production activity to the FTZ Board (the Board) for its facility in Summerville, South Carolina within FTZ 21. The notification conforming to the requirements of the Board's regulations (15 CFR 400.22) was received on July 31, 2026.

Pursuant to 15 CFR 400.14(b), FTZ production activity would be limited to the specific foreign-status material(s)/component(s) and specific finished product(s) described in the submitted notification (summarized below) and subsequently authorized by the Board. The benefits that may stem from conducting production activity under FTZ procedures are explained in the background section of the Board's website—accessible via www.trade.gov/​ftz.

The proposed finished product is solar photovoltaic modules, comprised of connected half cut monocrystalline silicon heterojunction photovoltaic cells sealed between two layers of low iron glass, framed with aluminum and with an added junction box on the back (duty-free).

The proposed foreign-status materials/components include low-iron patterned ARC solar glass double coating—1297*2378*2 mm, low iron solar patterned rear glass/float glass—1297*2378*2 mm, and G12 or G12R monocrystalline heterojunction cells (duty rate ranges from duty-free to 5%).

The request indicates that certain materials/components are subject to duties under section 301 of the Trade Act of 1974 (section 301), depending on the country of origin. The applicable section 301 decisions require subject merchandise to be admitted to FTZs in privileged foreign (PF) status (19 CFR 146.41). The request also indicates that crystalline photovoltaic cells are subject to an antidumping/countervailing duty (AD/CVD) order/investigation if imported from India. The Board's regulations (15 CFR 400.13(c)(2)) require that merchandise subject to AD/CVD orders, or items which would be otherwise subject to suspension of liquidation under AD/CVD procedures if they entered U.S. customs territory, be admitted to the zone in PF status (19 CFR 146.41).
