When the Biden administration announced a 15% tariff on a wide range of imported goods, headlines focused on higher import costs. Yet the real story lies in the exemptions that could shape the housing market, construction industry, and even mortgage approvals. Understanding these carve‑outs is essential for anyone buying, selling, or investing in real estate.

The New 15% Tariff: What It Means

The tariff, imposed under section 122 of the Trade Act of 1974, is a tool the U.S. has used to address trade imbalances. Unlike past broad tariff waves, this one comes with strategic carve‑outs designed to protect supply chains and trade agreements. The measure targets goods that are not produced domestically in sufficient quantities, but it leaves many critical inputs untouched.

Strategic Exemptions and Their Rationale

Key exemptions include goods from Canada and Mexico under the USMCA, as well as products from CAFTAR nations such as Costa Rica, the Dominican Republic, El Salvador, Guatemala, Honduras, and Nicaragua—particularly textiles and apparel. The tariff also exempts automotive parts, aerospace components, electronics, semiconductors, active pharmaceutical ingredients, agricultural staples, energy products, critical minerals, and fertilizers. These exclusions aim to preserve essential supply chains and avoid stacking with other duties like those under sections 232 and 301.

How the Tariff Affects Housing and Construction

Construction inputs such as steel, aluminum, copper, and lumber are largely exempt, preventing a direct spike in building costs. However, the removal of the $800 duty‑free exemption for low‑value imports means small contractors and flippers may face higher material costs. Energy costs, which influence construction expenses, transportation, and mortgage rate pressure, could also rise, affecting affordability and mortgage approvals.

The Ripple Effects on Local Markets

While the tariff is not a blanket inflation bomb, its selective nature can create localized price pressure and short‑term supply shifts. Market uncertainty may alter buyer psychology, influencing listing strategies, negotiation leverage, and timing. These dynamics underscore why real‑estate professionals must factor trade policy into their market analyses.

Why Real Estate Professionals Should Pay Attention

Those who move ahead of the crowd—buyers, sellers, investors—gain a competitive edge by anticipating how macro policy impacts micro markets. Understanding the exemptions and potential cost shifts allows agents and investors to build strategies before the next shift, ensuring they remain ahead of market changes.

In a landscape where trade policy can ripple through construction costs, energy prices, and mortgage approvals, the new 15% tariff’s exemptions are a double‑edged sword. They shield critical supply chains while nudging certain costs upward. For anyone navigating the housing market, staying informed about these nuances is not just prudent—it’s essential for making sound investment decisions.
