NMFC 185990 - Wood or Metal Rim Sieves | Class N/A

To find the correct freight class for your shipment:

1. Nest sieves rim-to-rim with a corrugated pad between faces, then strap around the rims (not across the mesh) to a pallet. Example: 18" wood-rim sieves, 5-high stacks, two perimeter straps.
2. For single shipments, use double-wall cartons with edge guards and a rigid insert protecting the screen. Pack vertical and label “Do Not Stack on Face.”
3. For large riddles (24–36 in.), pair face-to-face, tie with soft strap, add corner posts, and stretch-wrap securely to avoid mesh abrasion during cross-dock handling.
4. On the BOL, write “Sieves, wood rim, or riddles—metal or wood rim—NMFC 185990, non-hazardous,” and include piece count, pallet count, and dimensions for clean rating.

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

• Correct NMFC 185990 usage reduces reclass fees and billing disputes, keeping LTL invoices predictable.
• Rim-focused securing prevents mesh crush and puncture, cutting damage claims and replacement costs.
• Nested, face-to-face packing lowers cubic footprint, improving rate tiers and maximizing trailer space.
• Clear BOL descriptions speed terminal handling, reducing delays and accessorial risk for time-sensitive jobsites.
