Sodium Per Carbonate
Sodium percarbonate is a white, crystalline powder used as an oxygen bleach and disinfectant in laundry detergents and cleaning products. It falls under HTS 2836.99.50 as a peroxocarbonate (percarbonate) of an inorganic base (sodium), distinct from carbonates in other subheadings. When dissolved in water, it releases hydrogen peroxide and sodium carbonate for effective stain removal.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified purely as sodium carbonate without peroxide content
Lacks peroxo group, falling under simple carbonates of inorganic bases per heading 2836 structure.
If marketed primarily as a hydrogen peroxide source
Peroxides like hydrogen peroxide itself are in 2847; percarbonates may shift if not emphasized as carbonate derivative.
If imported as a formulated cleaning preparation
Mixtures or preparations for retail sale move to Chapter 38, not pure chemical compounds.

Import Tips & Compliance
• Verify purity and ensure the product qualifies as 'chemically defined' per Chapter 28 Note 1 to avoid reclassification
• Include Safety Data Sheets (SDS) and confirm peroxocarbonate composition via lab analysis for CBP scrutiny
• Watch for common pitfalls like mislabeling as sodium carbonate (2836.20), which has different rates
