OVERVIEW

Importing Solar Panels, Photovoltaic Cells & Solar Equipment from South Korea

Importing solar panels from South Korea into the United States carries low compliance risk, with an effective duty rate of Section 201 + 0% KORUS. A Section 232 Tariff Rate Quota (TRQ) arrangement applies: steel and aluminum products within quota limits may enter at reduced or zero Section 232 duty, while above-quota imports face the full 25% surcharge.

Solar Panels imported from South Korea 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 — South Korea Origin

Korean solar manufacturers (Hanwha Q Cells) have significant US presence. KORUS provides zero base duty. Section 201 applies. Hanwha Q Cells operates a major US factory in Georgia.

COMPLIANCE — Commerce (AD/CVD) / CBP / DOE / UL/NRTL

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

FREQUENTLY ASKED QUESTIONS

FAQs — Importing Solar Panels from South Korea

What is the effective US tariff rate for importing solar panels from South Korea?

The effective US tariff rate for solar panels from South Korea is: Section 201 + 0% KORUS. Korean solar manufacturers (Hanwha Q Cells) have significant US presence. KORUS provides zero base duty. Section 201 applies. Hanwha Q Cells operates a major US factory in Georgia.

What compliance agencies regulate solar panels imports from South Korea?

Solar Panels imports require compliance with: Commerce (AD/CVD), CBP, DOE, UL/NRTL. Specific requirements include: Section 201 Safeguard Tariff on crystalline silicon photovoltaic (CSPV) cells and modules — additional tariff declining annually through 2026; first 5 GW of cells exempted and AD/CVD orders on solar cells and modules from China and countries where Chinese manufacturers have operations (Malaysia, Thailand, Vietnam, Cambodia).

What documents are required to import solar panels from South Korea?

Required documents include: Commercial Invoice with cell/module origin, wattage, and technology type; Packing List; Bill of Lading; Country of Origin Declaration with cell-level origin tracing (critical for AD/CVD and circumvention). Additional: UL 61730 or UL 1703 safety certification; UFLPA supply chain documentation (polysilicon sourcing, bill of materials tracing). Ensure all documents are prepared before the shipment departs South Korea.

How long does customs clearance take for solar panels from South Korea?

Typical timeline: 25–45 days (ocean freight); 5–10 days (air for urgent/small shipments). CBP clearance typically takes 1–3 business days for compliant entries. Complex entries (AD/CVD, formal entry review, or examination) may require 5–15 additional business days.

Are there Section 301 or Section 232 tariffs on solar panels from South Korea?

No Section 301 tariffs apply to South Korea-origin goods. Section 232 applies with a TRQ arrangement — steel within quota enters at reduced/zero Section 232; above quota faces 25%.

What Section 201 safeguard tariffs and AD/CVD orders apply to solar panel imports?

Solar panels face multiple layered trade remedies: Section 201 safeguard tariffs (25% in year 1, declining annually) have been applied to crystalline silicon photovoltaic (CSPV) cells and modules. In parallel, AD/CVD orders target Chinese-origin solar cells and modules (as low as Chinese cells assembled in other countries) — Case A-570-979 and C-570-980 imposed rates of 14.78%–240% AD plus 11.45%–15.97% CVD. The Uyghur Forced Labor Prevention Act (UFLPA) further scrutinizes polysilicon sourced from Xinjiang. Verify your specific panel's origin documentation carefully before importing.

How does the UFLPA affect solar panel imports and what documentation is required?

UFLPA creates a rebuttable presumption that solar panels with polysilicon from Xinjiang, China, are made with forced labor and are prohibited from entry. CBP has detained thousands of solar panel shipments. To rebut the presumption, importers must submit: complete supply chain documentation tracing polysilicon from mine to finished module, third-party audit reports, supplier attestations, bills of materials, and material safety data. CBP's UFLPA Entity List names specific Xinjiang polysilicon producers. If your solar supply chain cannot be traced to non-Xinjiang polysilicon sources, importation will be blocked.

What UL certifications and NEC code requirements apply to imported solar panels?

Solar panels (PV modules) must meet UL 61730 (photovoltaic module safety qualification) or equivalent IEC 61730 certification for US market entry. Inverters require UL 1741 listing. Installations must comply with National Electrical Code (NEC) Article 690. Many US utilities and installers require that panels bear the UL mark — verify the UL certification of the specific module before purchase. IEEE 1547 governs interconnection standards. State-level rebate programs (ITC, state incentives) may require additional documentation of panel provenance and efficiency ratings.

What does the KORUS FTA cover and how do I claim preferential treatment?

The US-Korea Free Trade Agreement (KORUS, effective 2012) has phased out duties on the vast majority of US-Korea trade — most goods now enter at 0%. To claim KORUS preference, have a valid origin certification from the Korean exporter (self-certification is permitted under KORUS). Goods must meet KORUS rules of origin requiring sufficient production in the US or Korea, with country-specific RVC or tariff shift rules by HTS code.

Are Korean electronics (Samsung, LG, SK Hynix) subject to any additional US tariffs?

No. South Korea is not subject to Section 301 tariffs. Section 232 TRQ applies to Korean steel and aluminum, not electronics. Korean electronics benefit from both KORUS FTA (0%) and the ITA (0% WTO multilateral rate), providing dual zero-rating. Major Korean brands have extensive US operations that further simplify compliance for distributors and importers.

How strictly does CBP enforce KORUS rules of origin for auto parts?

CBP has significantly increased KORUS auto parts origin verification, particularly for vehicles and major components. Importers should obtain detailed origin certifications from Korean suppliers including net cost calculations and production records. Korean auto parts manufacturers supplying global OEMs typically maintain robust KORUS documentation — request it proactively rather than waiting for a CBP CF-28 inquiry.
