In plain English
The Commerce Department found that solar panel makers in Laos are dumping products in the US market below fair value, triggering new import duties on those panels. If your business buys or installs solar panels, especially from Asia-Pacific suppliers, brace for higher costs as these tariffs take effect on your supply chain.
