How to Determine Your Class
To find the correct freight class for your shipment:
- Confirm density before booking: weigh the boxed or crated shipment and divide by total cubic feet of the package; use that density to select the proper class (50–400).
- Match packaging to the component: crate steel frames and hydraulic items, use boxes with foam or corrugated dividers for gaskets and cloths, and stack polymer plates vertically with edge protection.
- Control moisture and abrasion on filtration surfaces: bag cloths, sleeve manifold ports, add VCI or stretch wrap for metal parts, and block/braces inside crates to prevent plate chipping.
- Document specifics for clean audits: list materials (polypropylene plates, stainless manifolds, cylinders), note non-hazardous status, and include piece counts so carriers can verify NMFC 121100 quickly.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Accurate density-driven classing reduces LTL spend by aligning heavy, compact crates to lower classes while avoiding reclass charges on lighter boxed parts.
- Purpose-built packaging cuts damage on high-value plates and frames, preventing filtration surface scratches that trigger costly returns and downtime.
- Clear NMFC 121100 labeling and detailed contents speed quotes and pickups, improving dock throughput and shortening lead times for maintenance shutdowns.
- Right-size boxes or consolidated crates increase density, often improving class and stabilizing freight rates for recurring wastewater or mining orders.
