NMFC 123230 - Gas/Liquid Accumulators & Purifiers | 77.5–85

To find the correct freight class for your shipment:

1. Purge and drain units before pickup; cap or plug every port and valve. Example: bleed a refrigeration receiver and thread on steel caps to protect fittings.
2. Match packaging to the build: crate complex assemblies with gauges or sight glasses, box smaller purifiers with foam, or palletize heavy receivers and band them tight as approved loose freight.
3. Stabilize and mark orientation. Use blocking/bridging inside crates, center-of-gravity labels on skids, and “This Side Up” or lift-point tags to prevent tip and crush damage.
4. Write the BOL clearly: “Accumulators/Distillers/Purifiers/Receivers/Regenerators, gas or liquid, NMFC 123230, Class 77.5–85,” include piece count and packaging type (loose, boxes, or crates).

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

• Predictable rating across multiple devices keeps quotes consistent and reduces reclass disputes for mixed shipments of receivers, distillers, and accumulators.
• Non-hazardous status streamlines paperwork and avoids hazmat surcharges, speeding dock throughput and cutting administrative cost.
• Right-sized packaging (boxed or crated when appropriate) can place freight at the lower end of the 77.5–85 range and reduces claim risk from exposed fittings.
• Standard Machinery Group handling means carriers recognize the commodity, improving acceptance and transit reliability for industrial and HVAC projects.
