The tariffs unveiled on Apr 21 vary widely depending on the company and country, but were broadly higher than the preliminary duties announced late last year.

According to the US Department of Commerce, solar cell and panel imports will face varying countervailing duties — as high as 3,403.9% for Cambodia, 799.5% for Thailand, 542.6% for Vietnam, and 168.8% for Malaysia.

These countries accounted for 77% of US solar panel imports in 2024, according to Bloomberg NEF.

The move delivers a heavy blow to the region’s renewable energy manufacturing sector, with Vietnam among the hardest hit.

It follows a year-long trade investigation initiated at the request of US solar manufacturers complaining that Chinese companies operating in Southeast Asia were allegedly dumping products and benefitting from unfair government subsidies, distorting the market. 

The case was brought by Korea's Hanwha Qcells, Arizona-based First Solar Inc and several smaller producers seeking to protect billions of dollars in investments in US solar manufacturing.

Industry insiders consider the new tariff alarming, representing a major shock to Vietnam's green energy export industry. 

The US has been one of Vietnam’s largest markets for solar equipment. The new tariffs will increase costs and risk, causing Vietnamese manufacturers to lose market share in the US. 

Renewable energy companies are under immense pressure, and without swift adaptation, the loss of the US market and revenue shortfalls in the near future are highly likely. 

It is urgent for Vietnam to pivot quickly, expanding into new markets including Europe, Japan and Australia, while enhancing competitiveness and adhering more strictly to international standards to overcome the growing wave of trade barriers.

In order for the tariffs to be finalised, the US International Trade Commission (ITC) is expected to vote in June based on its assessment of the actual damage to the US domestic solar manufacturing sector.

US levies anti-dumping duties on Vietnamese solar panels

VOV.VN - The United States Department of Commerce (DOC) has announced plans to impose preliminary anti-dumping tax ranging from 21% to 217% on solar panels imported from four Southeast Asian countries, including Malaysia, Cambodia, Thailand, and Vietnam, according to details given by the Trade Remedies Authority of Vietnam (TRAV).
