Note 89936: NOTE-Applies on extruded shapes consisting of one piece of graphite instraight lengths of uniform cross-sectional dimensions.

To find the correct freight class for your shipment:

Confirm the exact item fit: graphite boxes, bricks/briquettes for alloying, crucibles, nozzles/stopperheads, metalworking utensils (NOI), or extruded lineal shapes not machined. Package only in boxes, crates, or packages as specified.
Determine density per Item 170: weigh the shipment gross (with packaging), measure outside dimensions, convert to cubic feet, then divide weight by cubic feet. This pcf sets the class within 50–400.
Protect brittle carbon edges and surfaces: double-box crucibles with foam rings, bag parts to contain carbon dust, add corner boards and rigid spacers for extrusions, and layer bricks with pads inside a crate.
Document clearly: list NMFC 89935 with a precise description (e.g., “Graphite Crucibles, in boxes”), note density in lb/ft³, packaging type, and “Non-Hazmat.” For extruded shapes, verify “not machined” and see Note, item 89936.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

Density-driven rating rewards tight packing: higher pcf often earns a lower class, cutting LTL charges for dense bricks or tightly crated crucibles.
One NMFC for many graphite forms simplifies tenders, reduces reclass risk, and speeds audits across foundry, steel, and machine shop shipments.
Right packaging minimizes chipping and dust loss, reducing damage claims and preventing contamination of precision metalworking components.
Non-hazardous status broadens carrier options and accelerates booking, improving service levels without hazmat surcharges.
