Southwire Manufacturing Locations & the N93 Crimper: Where Is Southwire Actually Made?

It's late, you've got a deadline, and the question on your screen is simple: Southwire made in which country? Maybe you're looking at a spool of THHN, a roll of Romex, or a Southwire-branded crimper with N93 stamped on the side. The answer matters because jobsite specs, Buy American clauses, and inspection deadlines don't care about vibes.

I've spent the last few years coordinating rush orders for electrical contractors. In my role triaging material requests—some with same-day turnaround—I've learned to stop assuming that an American brand always means a U.S.-made product. Southwire is a good example. It's a U.S. company, but not every product in its catalog comes from a U.S. plant. Last quarter alone, we processed 47 rush orders with 95% on-time delivery, and the near-misses taught me to check country of origin before promising a date.

The surface problem: You just need to know where it's made

Most people asking about Southwire manufacturing locations aren't looking for a company history lesson. They need a specific answer: can I use this product on this job without losing my inspection?

That's a fair concern. Electrical inspectors don't usually ask where wire was manufactured. But they do check for UL marks, code compliance, and sometimes country of origin on government work.

So let's separate the questions.

What Southwire actually is

Southwire is headquartered in Carrollton, Georgia. It was founded there in 1950 and remains one of the largest wire and cable manufacturers in North America. The company makes a broad range of electrical products: building wire, service entrance cable, MC cable, UF-B cable, THHN/THWN-2, bare copper, and the Romex SIMpull NM-B that residential contractors know.

But Southwire also sells tools, connectors, testers, and accessories. Those products are not all made on the same assembly lines as the wire. In fact, many Southwire-branded hand tools are imported. That's where the N93 made-in-which-country confusion starts.

Southwire manufacturing locations: The ones that matter

I'm not a plant engineer, so I can't walk you through every process line. What I can tell you from a procurement perspective is which locations show up most often in real product shipments.

Southwire's public corporate information lists manufacturing and distribution facilities across North America. The exact list changes as plants expand, close, or get reorganized, so I won't pretend to give you a fully current map. But there are three anchor locations that come up again and again:

• Carrollton, Georgia — headquarters, engineering, and cable manufacturing. This is the site most people think of when they say Southwire.
• Osceola, Arkansas — a major copper wire and building cable plant. It's been a key part of Southwire's U.S. building wire production for years.
• Heflin, Alabama — a major aluminum conductor facility, producing overhead conductor and related products.

The bigger point for a contractor is this: when a standard Southwire electrical wire product comes through an authorized U.S. distributor, it is very likely from a U.S. plant. But likely is not guaranteed.

What Southwire electrical wire labels actually tell you

If you're holding a spool of Southwire THHN or Romex, the printed jacket is your first source of truth. The gauge, insulation temperature rating, UL listing, and often a plant or mill code are marked there. If you need proof of country of origin, keep the original reel tags and paperwork.

One thing I see contractors mix up: UL certification is not a country-of-origin statement. A product can be UL listed and manufactured outside the U.S. So when the project says made in USA, you need to check the label, not just the logo.

In a rush situation, it's tempting to look at a brand name and move on. I've seen that shortcut fail. One client had a Buy American requirement that meant every electrical component had to be traced. The Southwire wire was fine, but we had to pull the paperwork together under a tight deadline. It took a phone call and a copy of the receiving docs, not a guess.

The hidden cost of guessing wrong

Here's a concrete example. In March 2024, a client called about 36 hours before a rough-in inspection. They'd been offered a deal on Southwire-equivalent THHN from a reseller they'd never used. The price was good. The catch: the spools had no lot numbers, the labels looked generic, and nobody could confirm the country of origin.

We paid a little more to get the correct Southwire THHN from an authorized distributor. The client wasn't happy about the extra cost at first. But the alternative was pulling thousands of feet of wire out of conduit if the inspector flagged it. On a project with a completion penalty, that would have been far more expensive.

That's the part people forget: the cheapest spool is not the lowest-cost spool if it fails inspection or triggers a rework.

The N93 crimper: Made in which country?

Now, about the crimper. If you searched N93 because you're looking at a Southwire-branded hand tool, here's the direct answer: the N93 is not a cable and not a wire type. It's a model number for a crimping tool.

Southwire-branded hand tools, including the Southwire N93 crimper, are not typically made in Southwire's U.S. wire plants. Most of the hand tools in this part of their lineup are manufactured overseas, with China being the most common country of origin that shows up in product listings and packaging.

I can't give you one universal answer that covers every batch, because country of origin can change between production runs. The N93 you're holding should have a Made in label on the handle or packaging. If you bought it secondhand or without packaging, check the stamping on the body. The honest answer to whether every Southwire product is made in the USA is no. The honest answer to whether Southwire wire is made in the USA is: most of the time, yes, but verify for your specific product.

If a project requires domestic manufacturing, don't rely on the brand name alone. Ask for the product's country-of-origin certificate or check the packaging. That's what I do when a client says they need it legally sourced.

How to verify before you order

Here's a quick checklist I use when a rush order involves Southwire products:

• Look at the fine print. Genuine Southwire spools and products have clear labeling, model numbers, and traceability marks.
• Save the tags. The original reel label often includes the manufacturing location or mill code.
• Buy from an authorized distributor. That doesn't guarantee every item is made in the U.S., but it cuts out the counterfeit risk.
• Ask directly. A distributor can request country-of-origin information from Southwire or their warehouse. It's a normal question.
• Treat the N93 crimper as a tool, not a compliance component. The connector and the crimp quality matter more than where the crimper was built.

Bottom line

If you're asking Southwire made in which country, the answer depends on the product. The company is American, based in Carrollton, Georgia. Its wire and cable products, like THHN and Romex, are mostly made in U.S. plants such as Osceola, Arkansas, and Heflin, Alabama. The Southwire N93 crimper is a different story—it's an imported hand tool in most cases.

For the next emergency, don't reach for a brand name. Reach for the label, the spec sheet, and the paperwork. That'll get you through inspection faster than any guess.
