OVERVIEW
Importing Solar Panels, Photovoltaic Cells & Solar Equipment from Taiwan
Solar Panels imported from Taiwan to the United States is subject to CBP entry requirements, applicable HTS-based duty rates, and agency compliance clearances. This guide covers the complete import process for 2026.
⚠ Key Trade Intelligence — Taiwan Origin
Taiwan faces increased scrutiny under AD/CVD circumvention investigations if using Chinese wafers. Cell manufacturers using non-Chinese wafers have clearer compliance paths. Section 201 applies.
APPLICABLE HTS CODES
HTS Codes for Solar Panels Imports
The following Harmonized Tariff Schedule (HTS) codes typically apply to solar panels imports. Exact classification depends on the specific product — misclassification is one of the most common CBP compliance errors.
| HTS Code |
Product Description |
MFN Base Duty Rate |
| 8541.40 |
Photovoltaic Cells & Modules (crystalline silicon) |
0% MFN + Section 201 Safeguard |
| 8501.31–8501.34 |
Solar DC Generators & Inverters |
0%–2.5% MFN |
| 8541.40.60 |
Thin-Film Solar Cells (CdTe, CIGS, a-Si) |
0% MFN + Section 201 |
| 7610 |
Aluminum Solar Panel Mounting Structures |
2.8%–6.5% MFN + 10% Sec. 232 |
| 8507.60 |
Lithium-Ion Solar Storage Batteries |
3.4% MFN |
MFN rates reflect base tariff. Additional duties (Section 301, Section 232, AD/CVD) may apply on top of MFN rates. Use the AI classifier to get the exact 10-digit HTS code and all applicable rates for your specific product.

US Compliance Requirements for Solar Panels Imports
Regardless of origin country, solar panels imports must satisfy the following US regulatory requirements before or at the time of CBP entry filing:
- Section 201 Safeguard Tariff on crystalline silicon photovoltaic (CSPV) cells and modules — additional tariff declining annually through 2026; first 5 GW of cells exempted
- AD/CVD orders on solar cells and modules from China and countries where Chinese manufacturers have operations (Malaysia, Thailand, Vietnam, Cambodia)
- UL 61730 (IEC 61730) or UL 1703 safety certification required for solar modules sold and installed in the US market
- UFLPA (Uyghur Forced Labor Prevention Act) enforcement — CBP Withhold Release Orders on polysilicon and solar products with Xinjiang supply chain connections
