Hey everyone, it’s [Your Company, omitted] here, and if you’ve been in the semi-product game for more than five minutes, you know this: one month you’re quoting a custom aluminum extrusion for a regular client at $2.10 per foot, and the next, that same quote jumps to $2.75 before you even send the PO. No, it’s not us trying to pull a fast one—we’re a semi-product supplier, not price-gougers, and we deal with these wild price swings daily. Today I’m breaking down exactly what’s causing these fluctuations, straight from the floor of our warehouse and front of office where I field 12 “why the hell is this more expensive?” emails a week. Semi Product
First up, the big one that no one talks about enough: raw material volatility. When you’re making semi-products—think metal extrusions, plastic pellets, pre-cut glass panels, whatever you’re turning into a finished good later—your entire cost starts with the stuff you melt, shape, or mold. For us, that’s mostly aluminum, but I’ll use steel and plastic too because I get questions on those. Last year, for example, aluminum went from $1,800 a metric ton to $2,400 in 6 weeks because a major bauxite mine in Australia shut down for maintenance. That’s not a “supply chain issue” buzzword—it’s a literal hole in the ground not pulling ore out. I once had a client yell at me because their order of zinc-plated fasteners went up 30% out of nowhere; turns out a port in the Gulf of Mexico had a 2-week backlog, so freight rates for raw zinc tripled, and that got passed straight to us. Even recycling scrap metal (which we use for 40% of our inventory) isn’t immune—if scrap yards are short, they jack up their prices fast, because they’ve got their own buyers waiting. And plastic? Petrodollars, baby. When oil prices spike, PE and PP pellets go up overnight. Last quarter, a refinery fire in Texas made resin prices jump 18% in 48 hours; we had 3 clients whose POs from the week before suddenly needed a $0.50 per unit add-on. No warning, no heads-up. That’s raw material 101.
Next, supply chain snags that are way more specific than the generic “global delays” you hear on the news. I work with a lot of small to mid-sized manufacturers, so we don’t have the huge procurement teams that lock in long-term contracts. So when a freight line we use only for our specialty alloy bars cancels 5 ships because they got a bigger client (looking at you, auto industry), we’re scrambling. Last winter, we had an order of custom stainless steel tubes stuck in the Suez Canal for 10 days. Not the whole canal blockage, just our specific shipment. By the time it got to us, the delivery delay made our client miss their own production deadline, and we had to cover a portion of that (bad for our margins) but also raise the cost of that same tube for everyone else—because we paid extra to air freight a small batch to keep one line running. Then there’s part shortages. For us, we use specialty dies to shape our aluminum; if the factory in Germany that makes those dies has a backlog of 6 months, we can’t make new product, so any existing stock goes up because demand is higher than supply. We’ve also had issues with things like custom packaging materials—recently, cardboard boxes with our company logo on them were unavailable for 3 weeks, so we had to pay 2x for plain boxes to keep orders going. That’s not us being careless; it’s the tiny, easy-to-overlook parts that derail costs.
Labour costs are another huge one, and I swear clients act like we’re all sitting on a pile of cash not paying workers right. Let’s be real: our team doesn’t work in an airless office. They’re lifting 50lb boxes, operating heavy extrusion machines, standing on their feet 10 hours a day. Post-pandemic, we’ve had to raise wages 15% just to keep our current staff, and even then, we’re short 2 operators on the night shift. If we run short-staffed, we have to pay overtime, or bring in temp workers who charge double the hourly rate. That gets passed straight to the price of the semi-products. For example, last month we had a rush order for 10,000 pre-cut plastic sheets for a sign company. Our regular day shift couldn’t handle it, so we paid 2 temp workers $25 an hour more than our full team, and that added $0.12 per sheet to the final cost. Small number, but multiply that by 10k units, and it’s a big hit. Clients always ask why the same order from 6 months ago is cheaper—it’s because wages (and the supply of skilled labour) aren’t static. No one wants to work for $12 an hour in a factory anymore, and that’s a real cost we can’t absorb forever.
Oh, and let’s not forget regulatory and environmental costs, which have been skyrocketing the last couple years. Governments everywhere are cracking down on emissions, waste, and safety, and those costs don’t just apply to big corporations. For us, we have to pay for a waste management service to get rid of excess metal shavings from our extrusion machines, and that fee went up 22% last year because of new state environmental laws. Then there’s the cost of updating our equipment to meet new safety standards—last year, we spent $120k on new machine guards so we’re compliant with OSHA rules. That’s not a one-time cost; we have to spread that across every order we make for 5 years. And for manufacturers in the EU, carbon tariffs? If we export semi-products there, we have to pay extra fees for the carbon footprint of our production, which isn’t factored into most regular quotes. Last quarter, a client in Germany had their shipment of custom aluminum parts hit with a 10% tariff, and we had to adjust their invoice because that’s a new, mandatory cost we can’t take on. It’s not a scam—it’s the government adding fees that trickle all the way down.
Wait, also, demand and seasonality—this is the part I get roasted for the most. Let’s say you make lawn care equipment. Come February, everyone starts ordering parts for their summer mowers, right? So when our clients ramp up orders for aluminum frames, we see demand jump 300% in 2 months. We can’t just expand our factory overnight, so existing stock prices go up because we’re prioritizing loyal clients, and any spot orders get marked up. Last May, a guy came to us with a last-minute order for 500 aluminum gate frames—said his regular supplier let him down. We had to pull from our own stock that was reserved for a bigger client, so we charged him 25% more because we were missing that stock for our regular order. Seasonality isn’t just retail; it hits industrial stuff too. And if there’s a sudden trend? Like, a bunch of electric bike manufacturers popping up, all needing custom aluminum components? Demand spikes, prices go up fast because supply can’t keep up.
Now, before you think this is all doom and gloom, let’s be clear: we get it. Our clients are also dealing with their own price pressures from their customers. That’s why we try to be transparent about these factors when we quote, even if it means some pushback. If you’re a manufacturer working with semi-products—whether you make finished goods for construction, automotive, electronics, whatever—you’ve probably felt these swings too. And if you’re tired of getting surprised by price changes and want to lock in stable quotes, work with a supplier that will walk you through these factors, not just send you a number.
We’re not here to upsell you; we’re here to make sure you have the parts you need at a price that makes sense. If you have questions about how these factors apply to your specific semi-product needs, or want to chat about a new order, reach out to us to connect for a quick discussion about your requirements. We’re happy to break down any line item, explain why a price shifted, and figure out a way to make it work for both sides.
