Last updated: April 2026 dataExtracted primarily from brine and seawater, magnesium chloride serves the road de-icing, dust control, and magnesium metal production industries, and in food-grade form is used as a tofu coagulant (nigari) and dietary supplement. Classified under a single 10-digit line (2827310000), the product's grade and hydration state—anhydrous, hexahydrate flake, or brine solution—are commercially significant even though they do not subdivide the tariff line. Israel is the leading US supplier, drawing on Dead Sea brine resources, followed by the Czech Republic and the Netherlands.

Israel's Dead Sea Works and affiliated producers extract magnesium chloride as a co-product of potash and bromine recovery from Dead Sea brines, giving them a large-scale, low-cost feedstock advantage. This natural resource concentration makes Israel structurally competitive for both industrial and food-grade grades shipped to the US.
Food-grade magnesium chloride must meet FCC (Food Chemicals Codex) or USP specifications and is subject to FDA oversight as a food additive or dietary supplement ingredient. Importers should maintain certificates of analysis confirming purity and heavy-metal limits, and ensure the foreign manufacturer is registered with FDA. Classification remains 2827310000 regardless of grade, but FDA entry review applies to food-use material. Consult a licensed customs broker or regulatory counsel to confirm admissibility requirements.
