Last updated: August 2026 dataRefined linseed oil — pressed from flaxseed and further processed to remove impurities — serves as a critical drying oil in alkyd resins, paints, varnishes, and linoleum manufacturing. The refining stage distinguishes this product from crude linseed oil and determines its suitability for industrial versus food-grade applications. Importers should note that fractions (such as blown or polymerized variants) may be classified differently depending on their degree of chemical modification, making precise specification documentation essential at entry.

Refined linseed oil has undergone degumming, neutralization, bleaching, or deodorization to remove free fatty acids and impurities. Crude linseed oil that has not been through these processes classifies separately. Importers should ensure commercial invoices and certificates of analysis clearly state the refining process used, as misclassification between crude and refined can affect applicable duty rates.
Importers generally need a commercial invoice specifying the degree of refinement, a certificate of analysis indicating free fatty acid content and iodine value, and a bill of lading. If the oil is destined for food use, FDA prior notice may also be required. Consult a licensed customs broker to confirm current entry requirements.
