NMFC 187470 - Tributyltin Petroleum Solution | Class 50-65

Note 187471: NOTE-Does not apply on materials regulated by the U.S. Department of Transportation as hazardous and required to bear a Hazard Class or Hazard Division label or placard. For classes applicable to such hazardous materials, see provisions elsewhere in this Classification.

To find the correct freight class for your shipment:

1. Verify the blend is ≤5% tributyltin by weight and keep the SDS and Note reference (item 187471) in your paperwork to confirm non-hazmat status.
2. Use leak-tight inner containers (HDPE or metal) with sealed closures, add absorbent and a poly liner, then place inside strong corrugated boxes marked This Side Up.
3. Rate by shipment weight under the NMFC 187470 weight tiers; lighter boxes may bill at Class 65, heavier consolidated moves may qualify for Class 50—confirm the breaks with your carrier.
4. Secure cartons on pallets with stretch wrap and corner boards; avoid heat sources and segregate from oxidizers due to the petroleum carrier.

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

• Avoid hazmat surcharges and driver endorsements by shipping a non-labeled, ≤5% tributyltin solution.
• Weight-based classing (50–65) lets heavier moves earn lower classes and better LTL rates when consolidated.
• Correct box packaging reduces leakage risk, cutting claims, rework, and terminal delays.
• Clear documentation (SDS and concentration proof) speeds pickups and prevents misclassification disputes.
