Last updated: April 2026 dataAmmonium chloride—also known commercially as sal ammoniac—functions as a flux in galvanizing and soldering, a nitrogen source in fertilizer blends, and an excipient in certain pharmaceutical formulations. Classified under a single 10-digit line (2827100000), it is a commodity-grade inorganic salt with well-established specifications, but purity requirements vary significantly between industrial flux grades and food- or pharma-grade material. Germany leads US imports, with China and India as significant volume sources; buyers sourcing from China should evaluate Section 301 applicability.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
No—ammonium chloride is classified at 2827100000 regardless of whether it is destined for galvanizing, fertilizer blending, or pharmaceutical use. However, end-use grade (industrial vs. USP/food grade) is critical for FDA or EPA compliance purposes and should be documented in commercial invoices and certificates of analysis, even though it does not change the tariff line.
Industrial flux grades typically require 99%+ NH₄Cl content with controlled iron and heavy-metal limits. Pharmaceutical or food-grade material must meet USP or FCC monograph specifications, including strict limits on arsenic, lead, and sulfate. Importers should obtain third-party certificates of analysis and consider pre-shipment inspection, particularly when sourcing from suppliers not previously audited.
