NMFC 40200 - Metal Mask Canisters w/ Media | Class 70

To find the correct freight class for your shipment:

1. Use sturdy boxes or wood crates with inserts or dividers so metal canisters don’t rub, and cap or protect threaded ports to prevent damage.
2. Bag each canister to contain any loose filtering media dust, add desiccant packs, and mark cartons upright to protect adsorbent performance.
3. Palletize with no overhang, keep canisters upright, and secure with stretch wrap and corner boards; choose crates for heavier multi-layer shipments.
4. List the item exactly: “Canisters, gas or respiratory mask, metal, containing filtering media,” NMFC 40200, Class 70, non-hazardous, packaged in boxes or crates.

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

• Fixed Class 70 simplifies rating—no density math—reducing reclass and surprise fees.
• Non-hazardous status speeds booking and avoids hazmat surcharges and documentation costs.
• Proper boxing/crating cuts damage claims on threaded connections and media integrity, lowering returns.
• Clear packaging options (boxes or crates) let you match protection to load size, optimizing LTL freight spend.
