The US set final duties on solar cells from India, Indonesia and Laos, up to 249% combined for India
Commerce final determinations, announced 11 September: India 123.04% dumping plus 126.09% countervailing, 249.13% combined. Indonesia 94.36% dumping and 73.20% to 173.70% countervailing. Laos 65.43% dumping and 82.03% to 153.67% countervailing. An ITC injury decision is still to come.
Each time US trade rules close one supply route for solar cells, the panels arrive from somewhere else. This month three more routes closed.
PV Tech reported on 14 September 2026 that the US Department of Commerce finalised anti-dumping and countervailing duties on solar cells from India, Indonesia and Laos, announced on 11 September. For India the rates are 123.04% anti-dumping plus 126.09% countervailing, 249.13% combined. For Indonesia, 94.36% anti-dumping and 73.20% to 173.70% countervailing. For Laos, 65.43% anti-dumping and 82.03% to 153.67% countervailing.
A final step remains: the US ITC vote on whether the imports harmed US makers. Duties apply only if that vote goes in favour of the petitioners.
Analogy: it is a road with three new toll gates. Goods still travel. They take a longer route and cost more when they arrive.
Good: the rates are now final at Commerce, so buyers can price them rather than guess.
Bad: these three countries grew as suppliers after earlier US duties on other South-east Asian makers. Fewer cheap options remain.
Ugly: added to the Section 232 floor due in December, imported panel prices in the US now carry several layers of policy. A commercial quote needs to show its module origin.
