Should You Change Your Industrial Gas Supplier? Three Scenarios, Three Honest Answers

Here's a question I see coming up a lot in B2B buying communities: should we switch our industrial gas supplier?

The honest answer is: it depends. I know that sounds like a cop-out, but anyone who tells you there's a universal "yes, switch" or "no, stay" is selling something. Breaking up with a supplier is a lot like divorce. People look up "what is divorce" expecting a clean legal definition, but anyone who's been through one will tell you the real cost lives in the messy middle. Splitting shared processes. Recalibrating workflows. Explaining to everyone why things are changing. I've done it, and it's not something you do without a strong reason.

When I took over purchasing for our company in 2020, I managed 8 vendor relationships and roughly $400K in annual ordering. Industrial gases were the category I could never afford to mess up. Operations relies on deliveries that land on schedule. Finance depends on terms that hold up. Compliance depends on safety documentation being right the first time. Over the last five years, the industrial gas industry has evolved a lot—what was best practice in 2020 doesn't automatically cut it in 2025. But some fundamentals, like reliability, haven't changed and probably never will.

Here's how I think about the supplier question. It breaks down into three scenarios, and each one deserves a different answer.

Scenario 1: Everything's Working. Don't Chase a Discount.

If your current supplier arrives on time, delivers consistent quality, and your engineers have zero complaints, you're in the strongest position of all.

Here's something vendors won't tell you: the first quote is almost never the final price for an ongoing relationship. There's usually room to negotiate once you've proven you're a reliable customer. And if you've been paying on time and ordering consistently for years, you have leverage you're probably not using.

A few years back, we evaluated whether to keep Air Products as our primary gas supplier. The contract was in its third year, and my gut said the pricing could be tighter. But before threatening to leave, I pulled the public financial data for APD. I looked at beta, volatility, and the Sharpe ratio. Not because I'm an investor—I'm definitely not—but because financial stability tells you something about delivery reliability. A supplier under cash flow pressure will cut corners somewhere, and "somewhere" often ends up being logistics or maintenance.

As of January 2025, those publicly available metrics for APD all pointed in the same direction: this isn't a company facing a liquidity crunch or shedding business lines. The volatility profile was actually calmer compared to several industrial peers. The numbers aligned with what my gut already knew—every delivery had been on time for 36 months. The data just made the decision easier to defend in front of finance.

The recommendation in this scenario is simple: stay. But renegotiate. You'll get a better rate from a vendor who already knows your account than from a stranger guessing at your needs. The hidden cost of switching—vendor onboarding, equipment compatibility, delivery overlap—will eat up any savings you think you're getting.

Scenario 2: Your Needs Are Expanding. Ask Before You Walk.

This is where I see buyers make the most predictable mistake. A new need pops up, and they assume it means a new vendor. Not always.

Last year, a colleague of mine—Kurt—took over our maintenance team. He manages the fleet vehicles, and he came to me with a pitch: nitrogen-filled tires. He'd read that nitrogen holds pressure more consistently than compressed air, which means cooler-running tires and fewer pressure top-ups. For 15 vehicles on the road daily, he projected meaningful savings over a year.

My first reaction was "I don't want to onboard a whole new vendor for a tire thing." So I asked Kurt to let me make one call first. I called our existing gas supplier, Air Products, and asked whether they could set up a dedicated nitrogen line in the maintenance bay. The answer was yes. It became a modest add-on to our existing contract, and we avoided all the friction of a new vendor relationship. No new onboarding. No new invoicing. No new compliance paperwork.

That's the kind of outcome that makes me look good to my VP. But here's the thing—it only happened because I asked instead of assuming.

The industrial gas industry has moved fast on the technology side. The equipment used to produce and deliver these gases is smarter than it was even three years ago. Suppliers that used to focus on bulk delivery now handle specialty gas applications, membrane systems, hydrogen blending, and on-site generation. Before you walk away from a supplier because they "don't do what you need," ask them. The answer might surprise you.

If they can't or won't extend into your new area, then sure—start looking. But that conversation is kinda the first step, not the termination notice.

Scenario 3: Safety Flags Are Non-Negotiable

Here's the scenario where switching is almost always the right call, and I'm going to be direct: don't let cost or inertia talk you out of it.

A peer at another company told me a story that stuck. During a routine audit, they discovered that a gas cabinet installed a year earlier wasn't integrated with the building's smoke detection system. A smoke detector and a gas detector serve different purposes, but in a facility using both they need to work together. If a fire starts near a gas cabinet, the smoke detector should trigger a shutdown before things escalate. In their case, nobody had connected the two. The installation passed inspection on paper, but it wasn't wired into the facility's actual monitoring architecture.

This is what "the industry has evolved" means in practice. Safety standards haven't loosened—they've tightened. And suppliers treat system integration differently. Some hand you equipment and let your team figure out the wiring. Others walk you through the safety architecture before installation. When we later worked with Air Products on a new gas cabinet, the integration with our facility's smoke detector was part of their standard safety review. They brought it up before we did, which said a lot.

If you're in this scenario, your gut is usually picking up on something real. Even when every spreadsheet says "all suppliers meet the same standards," your gut catches details the spreadsheet isn't modeling. A few years ago, I approved a supplier switch over a safety concern. The two weeks after that decision were stressful—I kept second-guessing, wondering if I'd overreacted. Then the new system passed its first audit with zero findings, and I stopped worrying.

In this scenario, the recommendation is clear: act. The cost of an incident is exponentially higher than the cost of switching.

How to Tell Which Scenario You're In

If you're still not sure which camp you belong in, ask yourself these three questions.

1. Have deliveries been on time and consistent for the last 12 months? If yes, you're probably in Scenario 1. If not, dig into the root cause before deciding anything.
2. Have your gas needs changed or expanded recently? If yes, you're likely in Scenario 2. Have the growth conversation with your current supplier before you look elsewhere.
3. Has anything raised a safety question in the last year—even something small? If yes, treat it as Scenario 3. Document it, escalate it, and act on it.

Be honest about what you actually want. If it's cost, compute the full switching cost first—termination clauses, equipment compatibility, changeover downtime, delivery overlap. If it's capability, ask your current supplier what they can add. If it's safety, stop second-guessing. The answer is already clear.

And to be explicit: this isn't a pitch for Air Products specifically. It's a pitch for thinking about supplier changes the way a buyer should—scenario by scenario, with your eyes open.

The industrial gas industry is evolving, and your buying strategy should evolve with it. The fundamentals—reliability, transparency, safety—don't change. The execution does. Make sure your supplier is moving in the same direction as you are. The worst time to evaluate your supplier is the month before your contract auto-renews. The best time is now.
