US Import Duty on Solar Panels from China: Tariff Rates, Certifications, and Sourcing Strategy

After 20 years of sourcing from China, I’ve seen the solar panel market shift dramatically—especially with the US-China trade war adding a 25% tariff on top of standard duties. If you’re importing solar panels, understanding these rates isn’t just about compliance; it’s about protecting your margins. Here’s what you need to know before placing your next order.

Solar panels from China – production areas

The most popular cities providing solar panels are Ningbo, Yangzhou, Shenzhen, Shanghai, Guangzhou, Nanjing, and Huai’an. The factories are mainly placed in provinces like Zhejiang, Jiangsu, and Guangdong. These are the most industrialized Chinese provinces.

If you are looking for a trading company dealing with solar panels, it’s best to start searching in cities such as Ningbo, Shanghai, Nanjing, Huai’an, Yangzhou, Suzhou, and Guangzhou. The largest concentration of trading companies you mainly found in the same provinces as the factories listed above.

US duty rates on solar panels from China

Solar panels consist of many elements. There is a list containing chosen assembles. Before making an order, check for updated US duty rates on solar panels here. Assuming that you’re importing standalone solar panel components, it is required to have checked if they are completely compliant with local electrical safety regulations in your country.

Article – Heading/Subheading – Rates of duty

• Generators – 8501.31.81 – 2.5%
• Inverters – 8504.40.95 – 0%
• Diodes, other than photosensitive or light-emitting diodes (LED) – 8541.10.00 – 0%
• Crystalline silicon photovoltaic cells assembled into modules – 8541.43.10 – 0%

When calculating US duty rates on solar panels from China, you need to remember to check the additional tariffs. In matters of the current US and China trade war, the tariff is 25%.

Importing solar panels from China 

It’s best to choose goods with certificates, such as ECT (Electrical Safety Tester) and IEC (International Electrotechnical Commission). In the US, your solar panels need a Nationally Recognized Testing Laboratory mark (NRTL). There are many Nationally Recognized Testing Laboratories, of which UL is one (Underwriters Laboratories) – this certification is non-compulsory.

One of the highly popular and reliable quality management systems is the ISO9001 certificate. Make sure that the solar panel supplier in China of your choice is properly following a quality management system to ensure that you receive high-quality solar panels. We also advise you to conduct quality control and pre-shipment inspections.

Before signing the commercial agreement with your Chinese business partners, we recommended having the other company verified.

Before you commit to a supplier, always verify their quality certifications and consider a pre-shipment inspection to avoid costly mistakes. At China-Check, we help you navigate these risks with factory audits and product verification—so your solar panels arrive on time and up to spec.
