Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If marble-derived limestone, untarred
Untreated crushed marble or travertine lumps/chippings stay in raw marble heading 2515, not processed macadam.
If granules/chippings of marble, not tarred
Untarred marble granules under 6mm classify in 2517.41, separate from general tarred or slag macadam.
If tarred but primarily limestone flux for metallurgy
Limestone preparations for industrial flux use (even tarred) may go to 2521 if end-use shifts from construction aggregates.

Import Tips & Compliance
• Source limestone from verified HTS 2515 origins and test for tar adhesion strength to prove 'tarred' status
• Use moisture-proof packaging for powder/chippings to prevent degradation; declare net weight excluding excess tar runoff
