<h1>Indian rice exporters say US tariff threat and antidumping claim unlikely to curb exports; US consumers would mainly bear higher duties.</h1> Threatened additional US duties on Indian rice and a simultaneous antidumping allegation are central; exporters say staged tariff increases to the current 50 percent have not materially affected exports because US imports are a small share of India's global shipments, reject the dumping charge as unfounded, and point to market diversification and robust global demand such that further US tariffs would mainly burden US consumers rather than Indian export volumes.
