The 80/20 rule isn’t just theory—refractory distributors using it are doubling down on winners and retiring dead weight.
In the refractories sector, where dense bricks, castables, mortars, and monolithics flood catalogs with hundreds of product codes, the temptation is to carry a bit of everything. But when every product line ties up warehouse space, cash, and handling labor, “a bit of everything” quickly becomes a major burden.
Enter Pareto Analysis—a simple but powerful tool for rationalizing your refractory product offering.
Also known as the 80/20 rule, Pareto Analysis holds that roughly 80% of results come from 20% of causes. In product management, it often means that 80% of revenue is generated by 20% of SKUs. For refractory distributors, applying this lens can mean the difference between strategic growth and bloated stagnation.
Step 1: Pull the Right Data
Begin with 12–24 months of sales history across all product categories: firebrick (IFB, super duty), low-cement castables, gunning mixes, ramming materials, and insulating blankets. Include:
Units sold
Revenue contribution
Gross margin
Number of distinct buyers per SKU
Sort SKUs by revenue contribution and identify your top 20%. For most distributors, this segment is surprisingly small—often under 100 SKUs—but responsible for the lion’s share of revenue and reorder frequency.
Step 2: Layer in Strategic Filters
Raw volume tells only part of the story. A low-volume SKU may still be strategic if it:
Serves a key account with contractual volume
Enables bundled sales (e.g., castable + bonding mortar)
Acts as a spec-match for critical applications like ladle linings or kiln car decks
However, if a refractory mortar hasn’t sold in 18 months, has no named accounts, and overlaps chemically with an existing stocked product, it’s a prime candidate for retirement.
Step 3: Realign Procurement
One Eastern U.S. distributor applied Pareto and discovered that nearly 60% of stocked refractory products contributed less than 4% of revenue. Worse, these slow-movers were often ordered in low quantities to meet vendor MOQs, creating an endless cycle of overstock.
By removing or converting 140 SKUs into made-to-order items and doubling down on the top 75 performers, the company reduced working capital by $1.4M and improved turns by 29% over 12 months.
Their key move? Shifting supplier agreements to accommodate dynamic minimums and lead times. That freed the team to reallocate warehouse space to high-velocity castables used by regional cement and foundry clients.
Step 4: Communicate Internally
Your sales team needs to understand the “why” behind SKU changes. Training is crucial—particularly when retiring a familiar but underperforming brand of plastic refractory. Equip reps with talking points, substitution options, and clear customer benefit messaging.

Pareto isn’t just math—it’s a mindset. For refractory distributors, it provides a disciplined, data-driven way to spotlight what matters and shed what doesn’t. In a space defined by heavy materials, fluctuating demand, and labor-intensive handling, those who optimize their SKU base around true value—not habit—will always come out ahead.
