NMFC 50090 - Boiler Scale Compounds (Dry) | Class 55

To find the correct freight class for your shipment:

1. List the exact item on your BOL: “NMFC 50090 – Compounds, boiler cleansing/preserving/scale removing, dry – boxes, Class 55.” Clarity prevents reclass fees.
2. Capture accurate shipment weight per box and total weight; dimensions aren’t required for this weight-based class but help with space planning.
3. Use poly-lined or bag-in-box packaging to contain fine powders and block humidity. Stretch-wrap and top-sheet pallets to avoid moisture and sift-out.
4. If shipping the same product in bags or drums, confirm NMFC 50090 still applies with your carrier and attach an SDS for reference even though it’s non-haz.

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

• Class 55 rating delivers lower LTL rates for routine boiler treatment supplies, trimming recurring maintenance logistics costs.
• Non-hazardous status streamlines carrier acceptance and avoids costly hazmat accessorials or routing delays.
• Weight-only classification reduces density disputes, cutting the risk of inspections, reweighs, and surprise reclass charges.
• Boxed dry packaging stacks cleanly and protects product, lowering damage claims and improving dock turnaround time.
