Last updated: April 2026 dataTraded under the dual commercial names flaxseed and linseed, this oilseed serves two distinct end-use markets: food-grade flaxseed destined for human consumption (valued for omega-3 fatty acid content) and industrial linseed crushed for drying oils used in paints, varnishes, and linoleum. The distinction matters for regulatory routing — food-grade shipments fall under FDA oversight, while industrial-grade material does not carry the same labeling burden. USDA APHIS phytosanitary requirements apply at entry regardless of end use, and importers should clearly declare intended use in entry documentation to streamline clearance.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. Food-grade flaxseed intended for human consumption is subject to FDA review for labeling and safety compliance, while industrial linseed destined for paint or varnish manufacturing bypasses food-safety channels. Clearly stating the end use on the commercial invoice and entry documents helps CBP and FDA route the shipment correctly and avoids unnecessary holds.
Flaxseed production is concentrated in a small number of temperate growing regions, making supply sensitive to drought and crop-year variability. Moisture and mycotoxin levels during ocean transit are also a recurring concern; buyers typically require certificates of analysis confirming moisture content and absence of contaminants before shipment.
