U.S. imports of Crude Linseed Oil (SITC 42211) totaled $143K in August 2026, imported from 6 countries.
Importers of Crude Linseed Oil paid $13K in duties in August 2026, an average duty rate of 9.12% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Crude Linseed Oil imports of $143K in August 2026 ran 24% above the year-to-date monthly average of $115K.
Last updated: August 2026 dataLinseed oil — pressed from flaxseed — is classified as a drying oil due to its exceptionally high alpha-linolenic acid content, which causes it to polymerize and harden on exposure to air, making it a foundational raw material for paints, varnishes, linoleum, and wood-finishing products. Unlike most vegetable oils in this commodity group, crude linseed oil's primary market is industrial rather than food, though food-grade flaxseed oil (cold-pressed, unheated) occupies a separate niche in the nutritional supplement sector. Importers sourcing crude linseed oil for industrial use should confirm the product's iodine value and fatty-acid profile, as these determine drying speed and suitability for specific coatings formulations.

Both derive from flaxseed, but industrial crude linseed oil is typically heat-processed or solvent-extracted and may contain residual solvents or oxidation products that make it unsuitable for consumption. Food-grade flaxseed oil is cold-pressed under controlled conditions to preserve nutritional quality. The two products are handled under different regulatory frameworks — industrial linseed oil falls outside FDA food-safety oversight, while food-grade flaxseed oil is subject to FDA labeling and safety requirements.
Key specifications include iodine value (a measure of unsaturation and drying speed, typically 170–204 for linseed oil), free fatty acid content, moisture and volatile matter, and color (Gardner scale). Some coatings applications also require data on phosphorus content (indicating residual phosphatides) and peroxide value (indicating oxidation level). These parameters directly affect the oil's performance in drying-oil formulations and should be specified in the purchase contract and confirmed by a certificate of analysis.
