Related Products under Tariff item 2811.11.00
48% Hydrofluoric Acid Solution
A standard industrial grade of hydrofluoric acid at 48% concentration in water, used for etching glass and semiconductors. The solution is a normal and necessary method of putting up hydrogen fluoride for safety and transport, and the water does not render the product particularly suitable for specific use rather than for general use.
70% Hydrogen Fluoride Industrial Grade
A high-concentration 70% HF solution for heavy-duty applications like aluminum etching in manufacturing. It is explicitly hydrogen fluoride, meeting Chapter 28 note for inorganic acids of non-metals. The water solution is a normal method of putting up for safety and transport.
Aluminum Brightener HF Solution
An HF-based pickling solution for aluminum surface preparation in metal finishing. The primary active ingredient is hydrogen fluoride, and the solution is classified as hydrogen fluoride under tariff item 2811.11.00. Bulk imported for anodizing lines.
Anhydrous HF Gas Cylinder
Compressed anhydrous hydrogen fluoride gas in steel cylinders for fluorination reactions. Strictly pure hydrogen fluoride, an inorganic non-metal acid. Used in chemical synthesis plants.
Anhydrous Hydrogen Fluoride
Pure anhydrous hydrogen fluoride (HF) is a colorless, corrosive gas or liquid used primarily in industrial processes like fluorochemical production. It falls under tariff item 2811.11.00 as it is the specific inorganic acid.
Buffered Hydrofluoric Acid (BHF)
Buffered HF solution typically 6:1 HF:NH4F for silicon dioxide etching in microelectronics. Primarily hydrogen fluoride, thus classified under tariff item 2811.11.00 per Chapter 28 inorganic acids note, despite buffering. Imported for precision etching.
