NMFC 121550 - Liquid Level Flat Glass Gages | Class 65

Note 121552: NOTE-Applies only on flat glass gages used on pressure vessels or pressure piping systems to indicate the level of liquid contained therein.

To find the correct freight class for your shipment:

1. Declare NMFC 121550, Class 65, and note “in packages” on the BOL; reference Note item 121552 when applicable to match the instrument design.
2. Use double-wall cartons or wood crates with foam or molded inserts to isolate the flat glass from the heavy steel body; sleeve each glass pane and add edge guards.
3. Drain and clean the gage, cap all ports with plugs, secure loose hardware, then wrap the steel housing to prevent abrasion; label “Glass—Handle With Care” and orientation arrows.
4. For multi-piece shipments, keep each unit packaged separately and unitize to a pallet with strapping and stretch film; place corner boards and “Do Not Stack” cones to deter top load.

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

• Predictable costs with fixed Class 65 rating—no density calculation—reducing reclass risk and invoice disputes.
• Non-hazardous status streamlines paperwork and avoids hazmat surcharges, improving total landed cost.
• Purpose-built packaging guidance lowers breakage of flat glass and damage to steel bodies, cutting claims and reshipments.
• Clear NMFC tie-in (121550 with Note 121552) speeds carrier audits and accelerates rate approvals for machinery-grade instruments.
