Sodium Perborate Monohydrate
Sodium perborate monohydrate (NaBO3·H2O) is a white, odorless powder used primarily as an oxidizing agent and bleaching agent in detergents and cleaning products. It falls under HTS 2840.30.0010 as it is a chemically defined peroxoborate (perborate) of sodium, explicitly classified in the borates subheading for peroxoborates.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If disodium tetraborate (borax) without peroxide content
Borax is a simple borate under heading 2830, lacking the peroxy group that defines peroxoborates in 2840.
If imported as a formulated surface-active preparation like detergent powder
Mixtures containing sodium perborate as an ingredient for retail sale fall under Chapter 34 for cleaning preparations, not pure chemical compounds.
If blended with organic stabilizers for industrial use
Prepared chemical binders or additives not elsewhere specified shift to 3824, as they are no longer purely chemically defined inorganic peroxoborates.

Import Tips & Compliance
• Verify purity and hydration state (e.g
• monohydrate) via certificate of analysis to confirm classification under 2840.30.0010 and avoid reclassification as a mixture
• Include Safety Data Sheets (SDS) and ensure proper hazardous materials declaration for oxidizing solids during shipping
• Check for REACH or TSCA compliance; common pitfall is failing to declare peroxide content, leading to customs delays

Sodium Perborate Tetrahydrate
Sodium perborate tetrahydrate (NaBO3·4H2O), often called 'gem clips' in industry, is an anhydrous white crystalline powder that releases hydrogen peroxide in water for bleaching applications. Classified under HTS 2840.30.0010 as a peroxoborate of sodium per Chapter 28 notes for inorganic oxygen compounds.
Anhydrous Sodium Perborate
Anhydrous sodium perborate is the dehydrated form (NaBO3) used in high-performance bleaching formulations where water content must be minimized. It is specifically classified under HTS 2840.30.0010 as a peroxoborate (perborate), meeting the chemical definition for inorganic peroxy compounds in Chapter 28.
Technical Grade Sodium Perborate
Technical grade sodium perborate is a high-purity (95-99%) powder for industrial bleaching in paper and textile processing. It qualifies for HTS 2840.30.0010 as chemically defined sodium peroxoborate per Chapter 28 definitions, excluding organo-inorganic mixtures.
