NMFC 71690: Soldering Flux Liquids | Class 70–100

To find the correct freight class for your shipment:

1. List the hazmat details from the SDS on the BOL, including the proper shipping name and UN/NA ID, and provide a 24‑hour emergency contact.
2. Seal primary containers (e.g., HDPE jugs or metal cans) with leakproof closures, place them upright in sturdy or UN‑rated fiberboard boxes with absorbent and a liner, and apply required hazard labels and orientation arrows.
3. Palletize boxes upright, add poly sheeting or a drip tray, and segregate from food items, oxidizers, and heat sources; insulate if low temperatures could thicken the flux.
4. Reference NMFC item 71690 and select the appropriate class within 70–100 per carrier notes; schedule hazmat‑qualified LTL pickup to avoid refusals.

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

• Accurate NMFC and hazmat disclosure reduces reclass fees, carrier surcharges, and compliance risks.
• A set class range (not density‑based) streamlines quoting and audit reviews, saving rating time.
• Robust boxed packaging with absorbents cuts leakage claims and OS&D costs across the network.
• Complete SDS and documentation widen carrier acceptance for electronics and metalworking supply chains.
