How to Determine Your Class
To find the correct freight class for your shipment:
- Verify the SDS to confirm the product is non‑corrosive and non‑petroleum, then declare any hazmat attributes (UN/NA number, proper shipping name) on the BOL.
- Use sturdy boxes with sealed inner containers; add absorbent liner and leak‑proof bags for liquids, and apply orientation arrows and “This Side Up” labels.
- Plan around weight‑based rating: combine cartons when possible to reach better weight breaks that can move the shipment into a lower class within 65–100.
- Keep boxes away from heat and oxidizers, and include a 24/7 emergency contact for hazmat. Example: chelating rust removers or water‑based inhibitors packed in lined cartons.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Weight‑based classes let you lower LTL costs by consolidating boxes to hit more favorable breaks within the 65–100 range.
- Non‑corrosive, non‑petroleum chemistry reduces handling restrictions compared to acids or oils, helping avoid refusals and extra accessorials at metal shops.
- Accurate hazmat documentation prevents reclass, inspections, and fines, shortening dwell time and improving on‑time performance.
- Standard boxed packaging streamlines cross‑dock handling and damage prevention, reducing claims and improving landed cost for recurring industrial shipments.
