Heading 3402 explicitly covers surface-active and cleaning preparations 'whether or not containing soap,' so a cleaning preparation whose primary function is surface or object cleaning — rather than personal skin washing — falls under 3402 even if it contains some soap. The presence of soap alone does not push a product into heading 3401.

Subheading 340250 covers preparations put up for retail sale in packaging intended for the final consumer. Subheading 340290 covers the same types of preparations sold in bulk or industrial packaging not intended for direct retail. Presentation and packaging at the time of importation determine which applies.
