Notes

Note 91661: NOTE-Does not apply on materials regulated by the U.S. Department of Transportation as hazardous and required to bear a Hazard Class or Hazard Division label or placard. For classes applicable to such hazardous materials, see provisions elsewhere in this Classification.

How to Determine Your Class

To find the correct freight class for your shipment:

  1. Calculate density per handling unit: weigh, measure L x W x H in inches, then PCF = weight ÷ (cubic inches/1728). Example: 900 lb in 48x40x36 box = 900 ÷ 40 = 22.5 PCF; map class via Item 170.
  2. Use sift-proof, moisture-protected packaging. Poly-lined boxes or multiwall bags with heat-sealed liners keep hygroscopic gums (and sticky chicle) from clumping or bleeding through.
  3. Palletize tight for stackability: band, stretch-wrap to the deck, add corner boards, and cap sheets. Label: “Natural Gums, NOI – NMFC 91660” plus piece count and gross weight.
  4. Document clearly: note non-regulated for DOT, include SDS if available, and verify any commodity notes (see NMFC note 91661) before tendering to your LTL carrier.

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

Business Value

  • Density-based rating lets you improve PCF with smarter pack-outs, often dropping to a lower class for better LTL rates.
  • Non-hazardous status streamlines carrier acceptance, avoids hazmat surcharges, and widens carrier options.
  • Moisture and sift control reduce leakage and caking claims, protecting margins and service levels for confectionery and resin supply chains.
  • Accurate NMFC usage minimizes reclass fees and invoice disputes, speeding up billing cycles and improving landed cost predictability.
