Last updated: April 2026 dataGlass cullet and other glass waste and scrap serve as critical secondary raw materials for glass furnaces, reducing energy consumption and raw-material costs in container, flat, and specialty glass manufacturing. Cullet is traded by composition and color purity, since contamination or mixed colors can degrade melt quality and finished-product specifications. Importers should note that classification between glass in the mass and processed glass forms can be a recurring customs audit point, particularly when material has undergone partial processing.

Glass in the mass refers to unformed, molten or solidified glass not yet shaped into a usable product, while cullet is broken or waste glass collected for remelting. The distinction matters at customs because further processing or shaping may shift classification to a downstream glass heading.
Color segregation (clear, amber, green), contamination levels (ceramics, metals, organics), and particle size are the primary commercial specifications. Furnace operators typically require strict purity thresholds because off-spec cullet can cause defects in finished glass products.
