Last updated: August 2026 dataAbrasive cleaning preparations — including scouring powders, pastes, and creams used in household, industrial, and institutional cleaning — are classified under a single US tariff line (3405400000). The United Kingdom leads US import supply, followed by South Korea and Hungary, a geographically diverse sourcing profile that reflects both consumer brand exports and industrial cleaning product manufacturing. The heading's scope covers preparations whose primary function is mechanical or chemical abrasion for cleaning surfaces, distinguishing them from polishes (which restore or protect surfaces) and detergents (classified in Chapter 34 headings 3401–3402). Importers of combination products that both scour and polish should assess which function is primary to determine the correct heading.

The distinction turns on primary function: scouring preparations (340540) are designed to remove dirt, stains, or surface material through abrasion or chemical action, while polishes (340510, 340530) are designed to restore sheen, protect surfaces, or condition materials. A product that cleans by abrasion but also leaves a protective coating should be classified based on its predominant function as indicated by formulation and labeling.
Imports of scouring preparations originating from China may be subject to Section 301 tariffs, which apply broadly across many chemical product categories. Importers should verify the current Section 301 list status for the applicable HTS line (3405400000) and confirm the country of origin, as duty liability can differ significantly between Chinese-origin and other-origin shipments.
