These technological and regulatory developments are converging to reshape grower priorities, catalyze partnerships between input suppliers and AgTech firms, and accelerate investment in next-generation non-microbial biostimulants.

In 2025, a series of tariff measures implemented by the United States significantly altered the cost structure for imported non-microbial biostimulant ingredients. A universal 10 percent duty on all imports took effect on April 5, 2025, with higher reciprocal tariffs of up to 50 percent for countries identified with large trade imbalances commencing on April 9, 2025. These measures, layered on existing 25 percent tariffs for non-USMCA compliant imports from Canada and Mexico and 20 percent on certain Chinese goods, have compounded landed costs for biostimulant raw materials such as seaweed extracts sourced from Spain, Norway, and Belgium, as well as protein hydrolysates derived from animal and plant by-products.

The cumulative impact has been a recalibration of supply chains, with importers diversifying sourcing across Asia-Pacific and Latin America to mitigate tariff exposure, while domestic processors have accelerated investments in local production capabilities. However, the cost increases have also prompted price pass-through to growers, eroding margin structures and elevating end-user prices by an estimated 8–12 percent in key segments such as specialty fruits and vegetables. This tariffs-driven cost dynamic has underscored the strategic importance of local raw material development and vertically integrated manufacturing models, as stakeholders seek to balance supply security with affordability in a highly competitive agricultural inputs market.
