Products classified under HTS 2826.19.10.00

Ammonium Fluoride

Ammonium fluoride (NH4F) is a white crystalline salt used in chemical synthesis, glass etching, and as a fluorine source in pharmaceuticals. It falls under HTS 2826.19.1000 as an ammonium fluoride, classified within complex fluorine salts of Chapter 28. This chemically defined inorganic compound meets the chapter's criteria for fluorides other than those specified elsewhere.

Ammonium Bifluoride

Ammonium bifluoride ((NH4)HF2) is an inorganic acid salt applied in industrial cleaning, oil well acidizing, and metal pickling. Classified under HTS 2826.19.1000 as an 'other' ammonium fluoride complex. It qualifies as a chemically defined fluorine salt per Chapter 28 definitions, excluding organic derivatives.

Ammonium Fluorosilicate

Ammonium fluorosilicate ((NH4)2SiF6) serves as a rodenticide, water fluoridation agent, and in ceramic production. It is a complex fluorine salt classified in HTS 2826.19.1000 under 'other' fluorides of ammonium. Meets subheading note for chemically defined compounds.

Ammonium Fluorotitanate

Ammonium hexafluorotitanate ((NH4)2TiF6) acts as a catalyst in organic synthesis and titanium processing. Classified in HTS 2826.19.1000 as other ammonium fluorides. Complex fluorine salt meeting chapter chemical definition requirements.

Ammonium Fluorozirconate

Ammonium fluorozirconate ((NH4)2ZrF6) finds use in ceramics, nuclear fuel processing, and as a precipitant. Under HTS 2826.19.1000 for ammonium 'other' fluorides. Inorganic complex salt per subheading note.

Ammonium Fluoborate

Ammonium fluoborate (NH4BF4) is utilized in electroplating baths, explosives, and synthetic resins. Falls under HTS 2826.19.1000 as an ammonium fluoride complex. Chemically defined per Chapter 28/29 notes, distinct from organo-inorganics.

Ammonium Difluoride

Ammonium difluoride (NH4HF2 variant) used in beaker cleaning and synthetic fluoride production. HTS 2826.19.1000 classifies it as ammonium fluoride. Chemically defined simple fluoride salt.

Neutral Ammonium Fluoride

Neutral ammonium fluoride (pure NH4F anhydrous) for specialty etching and doping. Falls in HTS 2826.19.1000 as other ammonium fluorides. Excludes doped forms per chapter note on electronics.
