Part 1.Why Import Solar Panels From China

80% Dominance

China’s dominance in the solar photovoltaic (PV) component supply chain is unparalleled, accounting for 80% of global production capacity. This encompasses everything from raw materials to finished PV components. Such a stronghold is the result of over a decade of focused development in the photovoltaic industry, heavily supported by government subsidies aimed at fostering industry growth. Moreover, the availability of inexpensive labor in China has made solar products not only widely available but also highly cost-competitive on the global stage.

Part 4:Certification for Importing Solar Panels from China

IEC 61215 and IEC 61730

IEC 61215 and IEC 61730: These International Electrotechnical Commission standards verify the quality, safety, and performance of solar PV modules, essential for global trade.

UL 1703

Specifically for the North American market, this certification by Underwriters Laboratories ensures that solar panels meet stringent safety requirements.

CE Marking

A must-have for the European market, CE marking signifies that products comply with EU safety, health, and environmental protection standards.

Part 5: US Duty Rates on PV Panels from China

Navigating the complex landscape of US duty rates on solar panels from China is essential for importers looking to make informed decisions. Recent adjustments and policies have significant implications for the solar panel import market.

Recent Developments and Tariff Adjustments:

The US Department of Commerce has taken definitive steps to address circumvention inquiries concerning solar cells and modules from China. It was found that certain Chinese producers have been shipping their products through third countries for minor processing to avoid antidumping and countervailing duties (AD/CVD)​​. This crackdown reflects the ongoing efforts to ensure fair trade practices and compliance with US import regulations.

The Biden administration has upheld Section 201 tariffs, extending them while introducing a notable exclusion for bifacial panels and increasing the annual tariff rate quota for cells to 5GW​​​​. This move is seen as a balanced approach to support the domestic solar industry while acknowledging the need for imported solar cells and panels to meet the growing demand for renewable energy in the US.

A significant development came with the announcement of a 24-month moratorium on anti-circumvention duties on Chinese-branded solar panels and cells imported from Vietnam, Malaysia, Thailand, and Cambodia​​. This moratorium, expected to shield importers from additional duties, underscores the complexity of international trade and the efforts to maintain a level playing field.

Tariff Rates Overview:


Understanding the specifics of duty rates is crucial for importers. For instance, generators fall under a duty rate of 2.5% under the heading/subheading 8501.31.81. Inverters, crucial for solar power systems, are imported at a 0% duty rate under 8504.40.95. Similarly, diodes, excluding photosensitive or light-emitting diodes (LED), are also subject to a 0% duty rate under 8541.10.00. Notably, crystalline silicon photovoltaic cells assembled into modules fall under the heading/subheading 8541.43.10, with a 0% duty rate​​.

However, it’s important to note that these rates can be affected by broader trade policies between the US and China. The ongoing trade tensions have led to additional tariffs, notably a 25% tariff on solar panels, which adds another layer of consideration for importers​​.

Key Takeaways:


For businesses and investors looking to import solar panels from China, staying updated on the latest duty rates and trade policies is vital. The US government’s efforts to balance domestic industry protection with the need for imported solar technology highlight the dynamic nature of the solar energy market. Importers must navigate these complexities with diligence, ensuring compliance while optimizing their investment strategies.

In summary, the landscape of US duty rates on solar panels from China is shaped by a combination of long-standing tariffs, recent adjustments to address circumvention practices, and broader trade policies. Importers should closely monitor these developments to effectively navigate the regulatory environment and support the growth of renewable energy in the US.

Part 6: EU and China Solar Panel Dispute

The China-EU solar panel dispute marks a significant chapter in the global trade of renewable energy components, reflecting the complexities of international trade, protectionism, and the green economy. This dispute arose when the European Union accused China of dumping solar panels in the European market, a practice where goods are sold below their market value, often due to subsidies by the manufacturer’s government. This led to a conflict that threatened to escalate into a full-blown trade war between two of the world’s largest economies.

Background and Resolution:

The US Department of Commerce has taken definitive steps to address circumvention inquiries concerning solar cells and modules from China. It was The heart of the dispute lay in the EU’s allegation that Chinese companies were selling solar panels in Europe at prices below their normal market value, heavily subsidized by the Chinese government. This was seen as harmful to European manufacturers, who could not compete with the artificially low prices. In response, the EU imposed provisional anti-dumping duties on Chinese solar panels in 2013.

However, recognizing the importance of avoiding a trade war and the mutual benefits of cooperation in the renewable energy sector, both sides engaged in negotiations to find a solution. The dispute was eventually resolved when the EU and China agreed on a minimum price for Chinese solar panels sold in Europe. This agreement allowed Chinese panels to enter the European market without anti-dumping duties, provided they were sold at or above a mutually agreed minimum price.

Impact and Significance:


The resolution of the EU-China solar panel dispute was significant for several reasons. It averted a potential trade war, which would have had wide-ranging implications for the global economy, particularly in the renewable energy sector. It also highlighted the challenges and opportunities in balancing the promotion of renewable energy adoption with the protection of domestic industries from unfair competition.

The agreement underscored the importance of dialogue and cooperation in resolving trade disputes, especially in sectors crucial for achieving global sustainability goals. It demonstrated the need for fair competition in the global market, ensuring that the push for renewable energy does not come at the expense of undermining domestic industries through unfair practices.


The EU-China solar panel dispute serves as a reminder of the delicate balance between fostering the growth of the renewable energy sector and ensuring fair trade practices. It highlights the need for international cooperation and dialogue in addressing challenges that have both economic and environmental implications.

This dispute and its resolution provide valuable lessons for future trade conflicts, especially in industries critical to global sustainability efforts. The ability to find common ground and resolve disputes through negotiation rather than retaliatory measures is essential for promoting a sustainable and equitable global economy.
