How to Determine Your Class
To find the correct freight class for your shipment:
- Select the correct sub-item by packaging: boxed versus crated. List NMFC 138740 on the BOL and note bag/block counts and total weight.
- Protect viability: double-bag grain or sawdust spawn, line corrugated boxes, add gel ice packs, and label Do Not Freeze; use ventilated crates for larger pallets.
- Schedule early-week pickups and choose faster LTL service to avoid weekend dwell and heat exposure; request inside service for labs or farm facilities if needed.
- Palletize snugly with stretch wrap and corner boards, limit stack height, and leave airflow gaps around boxes to help temperature control during transit.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Accurate sub-item choice (box vs crate) keeps freight within the 70–100 range, preventing reclass fees and unexpected rate changes.
- Non-hazardous designation streamlines carrier acceptance and avoids hazmat surcharges, lowering total landed cost for spawn producers and farms.
- Durable, stack-ready packaging cuts damage claims and reships, preserving culture viability and customer trust.
- Consolidating small boxes onto a single crate reduces handling touches and can unlock better LTL pricing, especially in warm seasons.
