NMFC 68140 - Fertilizing Compounds, NOI | Class 50–110

Note 68144: NOTE-Will also apply when having a content of herbicides or insecticides admixed not to exceed five percent of gross weight of fertilizer.

To find the correct freight class for your shipment:

1. Confirm scope and hazards first: review the SDS and Note, item 68144 to verify the fertilizer compound qualifies as NOI and capture the proper shipping name and UN/NA data if regulated.
2. Compute density to pick the correct class: weigh the shipment and measure the outside dimensions of each box (or total cube if overpacked/palletized). Match the result to one of four density brackets to land between Class 50 and 110 (e.g., 900 lb over 30 ft³ ≈ 30 lb/ft³).
3. Package for containment and moisture control: use sturdy, sealed corrugated boxes or tight packages with liners to prevent leaks and caking. Secure closures and protect corners to avoid rupture under compression.
4. Ship hazmat-ready: book with LTL carriers that accept hazardous materials, provide a 24/7 emergency contact on the BOL, apply required marks/labels per the SDS, and anticipate a hazmat surcharge and potential handling restrictions.

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

• Optimized density can push freight into lower classes near 50, materially reducing LTL rates on bulk fertilizer moves.
• Using rigid boxes/packages minimizes spill risk and claims, protecting margins and customer relationships.
• Clean hazmat documentation prevents carrier refusals, rework, and reclassification charges that inflate total landed cost.
• Clear NMFC 68140 usage (with Note 68144 reference) speeds rating across carriers, shortening quote cycles and improving scheduling reliability.
