NMFC 169320 - Rennet Extract, Dry, in Boxes | Class 100

To find the correct freight class for your shipment:

1. Declare the commodity as “Rennet extract, dry, in boxes” and apply Class 100. No density calculation is required, which streamlines quoting and BOL entry.
2. Moisture is the enemy: use poly-lined cartons or liners inside boxes, stretch-wrap to the pallet, and add “Keep Dry” markings. Example: 25 lb poly-bag liners inside corrugated masters on a 48x40 pallet.
3. Protect product integrity: avoid co-loading with odor-heavy freight (cleaners, spices, perfumes) and keep away from high heat and humidity to preserve enzyme activity.
4. Include food ingredient documentation such as lot/batch numbers and COAs when requested by dairies or ingredient distributors, and mark cartons “Food Ingredient – Enzyme” for smoother receiving.

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

• Fixed Class 100 removes density disputes, cutting reclass fees and audit delays for predictable LTL costs.
• Non-hazardous status broadens carrier options and minimizes accessorial hurdles tied to hazmat handling.
• Consistent boxed packaging improves stackability and reduces OS&D risk, lowering claims and improving service reliability.
• Faster quoting and tendering thanks to a single, known class accelerates replenishment cycles for cheesemakers and ingredient suppliers.
