The tariff absorption wall.
Companies absorb cost increases until they can't. The wall arrives faster when you can't see your exposure by SKU.
When input costs rise (through tariffs, surcharges or currency), most mid-market manufacturers follow the same pattern. They absorb the first increase in margin. They absorb the second one partially. Then they hit a wall: margin on a meaningful share of the portfolio turns thin or negative, and price increases arrive late and blunt.
Why the wall comes as a surprise
Exposure lives at the level of the bill of materials. A tariff on one imported component can touch hundreds of finished goods, each with a different share of that component in its cost. Without that mapping, the impact appears in aggregate margin weeks later.
What visibility changes
- Exposure by SKU. Which finished goods depend on affected components, and by how much.
- Exposure by customer. Which accounts buy those SKUs, and what their contracts allow.
- Options by supplier. Which components have qualified alternative sources outside the affected origin.
The cost increase isn't the risk. Not knowing where it lands is.
A practical first pass
- Tag purchased components by country of origin and supplier.
- Roll the tag up through the BOM to finished goods.
- Rank finished goods by exposure × volume.
This is exactly the kind of cross-system join (purchasing data, BOMs, sales) that sits between the ERP and the spreadsheet. WERISCO does not read BOMs today, so this roll-up stays a spreadsheet exercise for now.
One supply-chain shock, decoded in numbers, and what a data-driven plant does about it.
