Vietnam: Column 1 rate + 12.5% additional
General (all other countries) | Photosensitive semiconductor devices ... Photovoltaic cells assembled in modules or made up into panels: crystalline silicon photovoltaic cells
Measure period 2018-02-07 – 2026-02-06. Year-by-year rates and quotas are in the 201 table on the Data page. Followed by the 232 polysilicon proclamation from 2026-12-04.
Cash deposits follow the company-specific rate (ACE case module). Coverage depends on each order's scope. The table below lists case numbers, status and the all-others rate. The all-others deposit rate is counted in the maximum exposure, not in the confirmed total.
| Case | Type | Product | Status | All-others rate | Deposit status | Determination |

China solar cell orders: Cambodia / Malaysia / Thailand / Vietnam anti-circumvention (2023): Cells made in Cambodia, Malaysia, Thailand or Vietnam from Chinese wafers, and modules made from such cells with more than two of six Chinese components (silver paste, frames, glass, backsheets, EVA, junction boxes), are treated as goods under the China solar cell orders (2012). Importers and exporters may certify out.
Which order applies: start from where the cell was produced. China → China solar cell orders (2012). Taiwan → Taiwan solar order. Cambodia / Malaysia / Thailand / Vietnam → that country's solar orders. India / Indonesia / Laos → that country's solar investigation. Modules assembled in China from non-Chinese cells → China solar products orders (2015). Where the module is assembled generally does not change the answer.
Open question: a module assembled in China from Taiwanese, Cambodian, Malaysian, Thai, Vietnamese, Indian, Indonesian or Lao cells may, on the wording, fall under both the China solar products orders (2015) and the orders on the cell country. CBP practice has not been confirmed. TBD
No ACE PGA flag on this line (requirements without a flag, such as FCC, DOE, SIMA and marking, still apply).

Period 2026-10-01 – 2027-09-30 · 91 FR 48398 (2026-07-31, Doc. 2026-15530, FY2027)
Southeast / South Asian origin: most CBP UFLPA detentions involve these countries (solar / electronics); be ready to show that upstream polysilicon, wafers, aluminum, cotton, etc. contain no Xinjiang inputs.
Triggered through the supply chain (regardless of origin): check upstream for Xinjiang inputs or Entity List companies | Statutory high-priority sector. Hoshine is listed under section (i), so Hoshine silicon at any tier triggers the presumption. Trace quartz → metallurgical silicon → polysilicon → ingot → wafer → cell → module.
From 2026-09-22 to 12-03 Commerce, with CBP, monitors polysilicon and derivative imports by importer of record (aggregate and weekly average since 2026-08-06 vs the 2026-01-01 to 08-06 and 2025 weekly averages, and use of affiliates that do not customarily import or of new IORs). An IOR found stockpiling, once notified by CBP, may not enter such goods for consumption before 2026-12-04 (bonded warehouse allowed); IORs registered on or after 2026-08-06 are limited per week to 12 kg of 2804.61.00, 7 kg of 3818.00.0020/.0040/.0045/.0050/.0091, 2,000 units of 8541.42.00 and 55 units of 8541.43.00. Waivers may be requested from Polysilicon232@bis.doc.gov (form at bis.gov/232), Commerce responds within 14 days.
