Refined Linseed (Flaxseed) Oil, Not Chemically Modified

Food-grade refined linseed oil must meet FDA standards for edible oils, including limits on peroxide value, free fatty acids, and contaminants, and the supplier's certificate of analysis should reflect these parameters. Industrial-grade refined linseed oil may contain additives or have higher acid values acceptable for coatings but not for consumption. The intended use and product specification — not just the HTS code — determine which regulatory pathway applies at entry.

Canada is one of the world's largest flaxseed producers, giving Canadian refiners a cost and proximity advantage for US supply. Geographic proximity reduces freight costs and transit time, and USMCA provides a favorable trade framework. This concentration means US buyers should monitor Canadian crop conditions and export availability when planning procurement.
