The fastest way to increase profit isn’t more sales—it’s fewer underperforming SKUs.
For glass, ceramics, and refractories distributors, revenue growth is only half the equation. The other half—and often the more elusive one—is profitability. In a market where float glass lead times can fluctuate by weeks and kiln shelves can sit for months, inventory that doesn’t earn its keep is a direct hit to your margins.
This is where margin-driven SKU rationalization becomes a game-changer.
Why Revenue-Based Product Planning Falls Short
Many distributors make the mistake of judging product performance by gross sales. A glass SKU that brought in $150,000 last year may look like a winner—until you factor in that it’s custom-cut, shipped LTL across provinces, and stored for long periods due to slow turns. Once freight premiums, spoilage risk, and handling costs are added, that “winning” SKU may have the lowest net margin in your catalog.
On the flip side, a simple 6”x6” ceramic tile SKU might sell $40,000 annually but with a 42% gross margin, fast turns, and strong reorder consistency. In a margin-driven model, that tile deserves more investment than the high-maintenance glass variant.
The Key Metrics That Matter
To rationalize SKUs through a profitability lens, start tracking and weighting the following:
Gross Margin per SKU
Turn Ratio (inventory velocity)
Carrying Cost per Unit
Customer Breadth (number of clients buying that SKU)
Fulfillment Complexity (cutting, packing, or hazmat handling)
Freight Sensitivity (weight-to-value ratio, LTL vs. FTL viability)
Each SKU can then be ranked into performance tiers:
Tier 1: High-margin, high-velocity, multi-client SKUs (e.g., clear annealed sheets, dense refractory bricks)
Tier 2: Moderate performers with niche applications but acceptable ROI
Tier 3: Low-margin, high-complexity, or single-client SKUs
This visibility empowers confident decisions. You may choose to discontinue Tier 3 SKUs, shift them to special-order status, or consolidate multiple underperforming variants into one high-turn alternative.
The Cultural Shift: From More SKUs to Better SKUs
Rationalizing SKUs is not about cutting options—it’s about focusing on the right ones. Distributors who adopt a margin-first mindset often see:
Warehouse efficiency gains from reduced pick errors and tighter slotting
Stronger vendor pricing through consolidated volume on fewer SKUs
Increased working capital by reducing inventory tied up in underperformers
Simplified sales enablement—your team can sell what you stock confidently
Crucially, this strategy also opens the door to reinvest. The capital freed from dead stock can be reallocated to fast-emerging lines—like specialty low-iron glass or next-gen ceramic insulators with EV applications.

SKU proliferation is easy. Margin management is hard. But in today’s high-cost, low-tolerance distribution environment, margin-driven SKU rationalization isn’t optional—it’s a growth strategy in disguise. Less truly is more when each product on your shelves earns its place.
