Products classified under HTS 2834.10.50.00
Sodium Nitrite Industrial Grade
Sodium nitrite (NaNO2) is a white to slightly yellow crystalline powder used primarily in the chemical industry for producing diazo dyes, nitroso compounds, and as a corrosion inhibitor. It falls under HTS 2834.10.5000 as an 'other' inorganic nitrite of sodium, chemically defined per Chapter 28 notes, excluding those covered by other specific headings. This classification applies to bulk industrial forms not meeting exclusions like organo-inorganic compounds.
Potassium Nitrite Powder
Potassium nitrite (KNO2) is a yellowish-white powder serving as an oxidizing agent in heat-transfer salts and a reagent in analytical chemistry. Classified under HTS 2834.10.5000 as an 'other' nitrite of potassium, it meets the 'chemically defined' criteria without organic components or exclusions listed in Chapter 28 notes. Used in industrial applications like metal treatment.
Calcium Nitrite Corrosion Inhibitor
Calcium nitrite (Ca(NO2)2) solution or powder acts as a corrosion inhibitor for reinforced concrete, preventing steel rebar rust. It is classified in HTS 2834.10.5000 as an 'other' inorganic nitrite, chemically pure and not excluded as a Chapter 31 product or organo-compound. Primarily used in construction chemicals.
Silver Nitrite Analytical Reagent
Silver nitrite (AgNO2) is a fine powder used as a reagent in organic synthesis and analytical labs for nitrate testing. Under HTS 2834.10.5000 as 'other' nitrites, it qualifies as chemically defined without precious metal exclusions since it's a compound, not pure metal (per Chapter 28 note 6(f)). High-purity lab grade.
Barium Nitrite Crystals
Barium nitrite (Ba(NO2)2) crystals are used in pyrotechnics and as intermediates in barium salt production. Classified HTS 2834.10.5000 for 'other' nitrites, pure inorganic form per Chapter definitions, not a complex salt or excluded product. Industrial chemical applications.
Ammonium Nitrite Stabilized
Ammonium nitrite (NH4NO2), stabilized to prevent decomposition, is used in gas-generating systems and lab applications. Falls under HTS 2834.10.5000 as 'other' nitrites including ammonium salts per heading 2826-2842 note, provided stabilization is inorganic. Excludes organic-stabilized forms in 2831.
Lithium Nitrite Solution 50%
50% aqueous lithium nitrite (LiNO2) solution serves as a heat transfer fluid additive and de-icing component. HTS 2834.10.5000 covers it as 'other' nitrite if chemically defined, but watch for mixture status; pure compound basis. Industrial fluid applications.
Strontium Nitrite Technical Grade
Technical grade strontium nitrite (Sr(NO2)2) is employed in specialty pigments and ceramic glazes. Under HTS 2834.10.5000 as 'other' inorganic nitrites, chemically defined without Chapter exclusions. Used in manufacturing.
Magnesium Nitrite Flakes
Magnesium nitrite (Mg(NO2)2) in flake form for agricultural and water treatment applications. Classified HTS 2834.10.5000 'other' nitrites; pure form, not section V product like MgO (Chapter note 7(a)).
