Decision Framework

How to Decide Between Local and Global Suppliers

Unit price comparisons are the wrong axis. Total landed cost — with the 30-40% inventory premium and tariff exposure most analyses miss — flips the decision far more often than intuition suggests.

The Hidden Costs Most Teams Miss

Inventory Carrying Cost — Global lead times of 6-16 weeks demand 30-40% more safety stock than 1-3 day local deliveries, like renting an extra warehouse you shouldn't need.

Tariff Exposure — Section 301 tariffs at 25%+ and China-specific tariffs at 35% can erase the entire unit price advantage. BCG estimates tariffs now risk 20-30% of manufacturing profit margins.

Quality & Defect Costs — Distant supplier defects cause rework and line stoppages that never appear in the sourcing spreadsheet. 83% of firms report downtime costs at $10,000+ per hour.

Compliance & Carbon Cost — The EU Carbon Border Adjustment Mechanism (CBAM) now imposes direct levies on high-emission imports, like a pollution surcharge at customs. Asian industrial products can carry 60% higher carbon footprint.

The Framework Shift

Old Way

Compare unit prices. Pick the cheapest sticker price. Ignore freight, tariffs, and inventory costs as footnotes.

Hidden costs erase margins

New Way

Calculate total landed cost with all 9 inputs. Map each category to BCG's four-quadrant sourcing matrix.

What Correct Execution Looks Like

Calculate TLC for every category above $500K. The 9 inputs — freight, tariffs, inventory, quality, currency, compliance — will surprise you on at least one category where the "obvious" answer is wrong.

Map each category to BCG's matrix. Innovation intensity drives one axis; supply market concentration and geopolitical exposure drive the resilience axis. Follow the quadrant's prescription.

Reassess annually. Tariffs change, supplier ecosystems evolve, and a category that belongs in global sourcing today may need local suppliers tomorrow — like rechecking a map when roads shift.

Risk

The single-axis trap: reducing a multi-variable decision to unit price alone. Most teams compare sticker prices, find the global supplier cheaper, and conclude global is right — without calculating any of the nine TLC inputs. This is like buying a car based only on the sticker price while ignoring insurance, fuel, and maintenance costs.

Jargon Decoder

TLC Total Landed Cost — the full price of getting a product to your door, including freight, tariffs, insurance, and inventory costs, not just the sticker price.

EBIT Earnings Before Interest and Taxes — a company's profit from operations, like take-home pay before the mortgage and tax bill.

CBAM Carbon Border Adjustment Mechanism — an EU tax on imports with high carbon emissions, like a pollution surcharge collected at customs.

Safety Stock Extra inventory kept on hand to avoid running out when supply lines are long, like keeping a spare tank of gas in the garage just in case.

Nearshoring Moving production to a nearby country instead of a distant one, like buying from the farm down the road instead of overseas.

Section 301 US trade law tariffs on Chinese goods — an import surcharge that can add 25% or more to the price tag before it even leaves customs.
