Shrinking your product list might be the fastest way to grow your bottom line.
For many North American distributors in the glass, ceramics, and refractories space, margin erosion isn’t due to pricing pressure alone—it’s tied to operational sprawl. SKU proliferation increases warehousing costs, slows turns, complicates purchasing, and fragments vendor relationships. That’s why SKU rationalization is gaining traction as a margin recovery tool, not just a supply chain cleanup tactic.
The case for rationalization is especially strong in 2025’s landscape: freight remains volatile, lead times are inconsistent, and working capital is under scrutiny. Every unnecessary SKU carries a hidden cost—and multiplied across hundreds of items, the margin leakage is real.
Hidden Costs of a Bloated SKU Portfolio
Higher Carrying Costs
Slow-moving SKUs consume shelf space, require periodic re-counts, and generate shrink risk—even if they only move once a year.
Poor Vendor Leverage
Spread purchasing across 20 suppliers for 80 refractories SKUs, and you dilute volume discounts, terms, and freight consolidation opportunities.
Increased Picking Errors
Similar SKUs (e.g., two insulating boards with only ¼” thickness difference) raise the risk of mis-picks and costly returns.
Fragmented Demand Signals
Procurement teams can’t consolidate buys effectively when demand is split across five versions of essentially the same item.
Steps Toward Strategic SKU Rationalization
Inventory ROI Analysis
Rank SKUs by contribution margin and velocity. Anything below a set ROI threshold becomes a candidate for review.
Customer Impact Review
Cross-reference SKU purchases with customer history. If only one client buys a refractory castable annually, consider shifting that to made-to-order.
Rationalization Workshops
Gather sales, purchasing, and ops leaders quarterly to review candidates for removal. Make it a cross-functional discipline, not just a warehouse issue.
Build Substitution Tables
Don’t just delete SKUs—offer clear, pre-approved alternates. This keeps sales teams confident and reduces customer pushback.
Track Gains
Quantify the freed-up warehouse space, reduced inventory cost, and purchasing efficiency gains. Show stakeholders the tangible impact.
Reinvest the Savings
Use freed-up capital to deepen inventory in your top-performing SKUs or to onboard faster-moving lines for high-growth segments.

SKU rationalization isn’t about limiting choice—it’s about eliminating clutter. For distributors under pressure to recover margin and improve working capital, it’s one of the few levers that delivers fast, measurable results without sacrificing service. In a market where every point of margin counts, less can truly be more.
