How to Determine Your Class
To find the correct freight class for your shipment:
- List NMFC 50317 and Class 70 on the BOL using the wording “Compounds, tire puncture, rim sealing, or tire balancing” to match the tariff description.
- Pack in sturdy boxes; for pressurized cans, use fiberboard dividers and apply Limited Quantity marks if eligible, or full hazmat marks, labels, and 24‑hr emergency contact when required.
- Weigh each carton accurately since rating is fixed at Class 70; add orientation arrows, keep away from heat, and line boxes with poly/absorbent to mitigate leaks.
- Review Note 50318 for exceptions and any drum provisions, and confirm carrier acceptance when shipping forms other than boxed pressurized cans.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Predictable Class 70 helps tire dealers and auto service distributors secure consistent LTL rates versus higher classes common to chemicals and aerosols.
- No density calculation reduces paperwork and reclass disputes, cutting accessorials and admin time on quotes and audits.
- Proper hazmat presentation lowers refusal risk, shortens dwell time, and can qualify Limited Quantity to reduce fees when permitted.
- Clear NMFC mapping standardizes BOLs across locations, improving training speed and compliance for fleet and aftermarket supply chains.
