Buying Fire Extinguishers by NSN (National Stock Number)

If you buy for a government installation, a prime or sub-tier defense contractor, or a fleet that supports one, requisitions often arrive as a National Stock Number rather than a brand and model. Searching that NSN mostly surfaces parts-broker pages: no stock, no price, just an RFQ form that starts a multi-day quote loop for an item that is sitting on a commercial shelf.

For the fire extinguishers below, there is a shorter path. Public NSN catalog data lists specific models we stock as cataloged sources for specific NSNs — with live pricing, inventory, and checkout on each product page. Cross-reference your NSN in the table below, confirm the part number against your requisition, and buy it like any other commercial purchase.

A National Stock Number is the 13-digit identifier the US government (and NATO) uses to catalog supply items. Using NSN 4210-01-245-9850 as the example:

• First 4 digits — Federal Supply Class (FSC): 4210 is the class for fire-fighting equipment, which covers portable extinguishers.
• Digits 5–6 — country code: 00 or 01 means the item was cataloged in the United States.
• Last 7 digits — serial: a non-significant number assigned to the specific item. The last 9 digits together are the NIIN (National Item Identification Number).

An NSN is not a brand — it identifies an item of supply. The catalog record behind each NSN lists one or more cataloged sources: specific manufacturer part numbers, each identified by that manufacturer’s five-character CAGE (Commercial and Government Entity) code, shown per row in the table below. Some NSNs have a single cataloged source; others list several manufacturers whose parts are interchangeable for that item of supply.

Each row below is a fire-extinguisher NSN whose public catalog record lists a model we stock as a cataloged source, with the manufacturer’s part number and CAGE code from that record. The table is generated from the same verified NSN reference each product page carries, and the links go to live pages with current price and inventory.

Each product page also shows its NSN reference, so a link into your procurement file carries the cross-reference with it. You can also search this site directly by NSN — with or without the dashes.

No certification, registration, or account setup is required to buy from us. For government buyers, the practical paths look like this:

• Government purchase card (P-card): below the federal micro-purchase threshold — $15,000 for most supplies as of the October 2025 inflation adjustment, with some exceptions — cardholders can buy direct from open-market vendors. Our checkout runs a purchase card like any other credit card. Confirm your agency’s current limits and any local policy with your program office.
• Prime and sub-tier contractors: buying commercial items to support a government contract is an ordinary commercial purchase. Check the flow-down clauses in your contract for sourcing or origin requirements, then order online or request a quote.
• Formal quotes for procurement files: if your file needs a written quote before the order, use the quote form below — we return volume quotes with delivered pricing within one business day.

Buying for vehicles? DOT-regulated trucks carry their own extinguisher requirements independent of any NSN — see the DOT fire extinguisher requirements guide and the broader fleet & DOT compliance guide.

Counterfeit and gray-market parts are a real concern in NSN-driven supply chains, which is why buyers ask where an item actually comes from. The units we ship are genuine OEM production sourced through authorized channels — never brokered, relabeled, or surplus stock. Every product page links to its manufacturer’s brand page, which documents who the manufacturer is and where it produces.

Carrying American-made products is this store’s premise. For purchases with domestic-origin flow-downs, the manufacturer’s brand page gives you a factual origin reference for your file — whether a specific clause (Buy American, Berry, or otherwise) applies to your purchase is a determination for your contracting officer, and we don’t make compliance claims on your behalf.

US Made Supply is a commercial, open-market distributor of US-made industrial and safety products. So there’s no ambiguity in your sourcing file:

• We do not hold a CAGE code or SAM registration. If your purchase must be placed with a SAM-registered vendor or through a contracting vehicle, we may not be an eligible source for that order.
• We are a fit for open-market purchases: P-card buys below the micro-purchase threshold, contractor purchases of commercial items, and volume orders quoted directly.
• “Cataloged source” is catalog language, not an endorsement. It means public NSN records list the part number for that NSN. We don’t describe items as military-approved or government-certified, because that isn’t what an NSN listing means.

Outfitting a facility, a vehicle fleet, or a contract line item usually means multiple units, mixed sizes, and delivered pricing for the file. Send the NSNs or part numbers and quantities and we’ll return a written quote — including a check of whether a product we carry is a cataloged source for any NSN you send that isn’t listed above.
