For over a decade, Half Hill Farm has manufactured popular functional mushroom supplements exclusively for customers across the United States. Starting today, we are announcing tariff and duty-free shipping for our friends in Canada!
Half Hill Farm's functional mushroom supplements are made using US grown, certified organic and responsibly wild-crafted, fully mature mushrooms with time-honored traditional extraction processes. Our products are made with patience in our FDA registered facility with cGMP compliance and the farm-to-bottle traceability our customers have come to trust for over a decade.
While most mushroom supplement makers quickly forged ahead into untapped markets using cheaper mycelium on grain powders, staying true to quality and our values has allowed us to reach this moment sustainably. But the number of US-based certified organic growers now meeting industry demand for quality isn't the only reason for this move.

Our decision to expand into Canada right now is about defiantly meeting a moment of fraught US politics that threatens our deep friendships and alliances. While divisive rhetoric and reckless tariffs attempt to burn the bridges between our countries, we believe that continuing to share the fruits of our labor across borders is the best antidote to those seeking to divide us.
Under the United States-Mexico-Canada Agreement of 2018 (USMCA / CUSMA / T-MEC), products that are "originating goods" (entirely sourced from our home countries) get preferential tariff treatment (0% duty). This framework honors the values of working people and the friendships formed shared freedom and prosperity. Because the US recently blocked the 16-year renewal of this agreement, it now faces expiration in 2036.
What that means is we have 10 years to strengthen our bonds under this framework as a bridge over the troubled waters of this moment.
While politicians argue over borders and tariffs, the laws that actually govern this free-trade agreement were written to guarantee that working people can share the fruits (or fruiting bodies) of their labor directly with their neighbors, tariff and duty-free. The treaty recognizes fully mature mushrooms as a product of the land we share, protecting our right to sell them in dietary supplement form freely across the border while better leadership works to protect these values further.
Our friendship and alliance is like the fungal networks quietly built underground by mushrooms that survived millennia of borders and much harsher conditions than the fires of the moment. We hope you meet us on this bridge where our wealth is defined by our collective health, and our longevity by shared values that defy borders and make us friends and neighbors!
