The lumber industry is seeing weaker demand in 2025, as the housing market slows from the pandemic-driven boom. In October of 2025, lumber prices are experiencing significant volatility amid the Trump administration’s new tariffs and supply chain disruptions. Despite the challenges, many lumber suppliers continue to thrive. In this article, we’ll detail the top lumber suppliers in the US by revenue, including Biewer Lumber, Hampton Affiliates, Sierra Pacific, and Weyerhaeuser.
What do the top lumber suppliers make?
Specific offerings may vary by company. Generally, lumber suppliers produce a range of softwood and hardwood products, including structural wood and wood flooring, as well as planks, pillars, and even wood chips and shavings.
Lumber suppliers can typically be contacted through their sales departments on their home website. They may also have showrooms or brick-and-mortar locations with samples.
