How to Determine Your Class
To find the correct freight class for your shipment:
- Calculate density from the full boxed shipment, not just inner packs. Example: a 18 lb carton measuring 12"×12"×12" (1.0 cu ft) equals 18 pcf, typically pricing near Class 70; around 9–10 pcf trends toward Class 100.
- Use molded trays or chipboard dividers to protect the ceramic insulator and terminals. Double‑wall cartons with snug void fill prevent plug-to-plug contact and chipped porcelain.
- Palletize master cartons with no overhang. Interlock stack, strap, and wrap; place heavier cartons low and mark “Fragile — Ceramic Insulators” for clearer handling.
- On the BOL, list “NMFC 177080 Spark Plugs, density class 70–100, boxed,” include piece count, weight, and carton dimensions, and mark as non-hazardous for simpler processing.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Accurate density entries can shift pricing from Class 100 toward Class 70 when packaging is compact, often cutting LTL rates and improving landed cost on small, heavy parts.
- Purpose-built inserts and double-wall boxes reduce breakage of ceramic insulators, lowering claim frequency and protecting customer satisfaction in aftermarket and OEM channels.
- Non-hazardous status eliminates hazmat surcharges and extra paperwork, speeding tendering and reducing administrative cost per shipment.
- Standardized, stackable master cartons improve trailer cube and carrier acceptance, supporting better contract discounts and steadier transit performance.
