The Hidden Iceberg of Global Procurement: Beyond Purchase Price
In global strategic sourcing, the invoice purchase price listed on a supplier's quotation often represents merely the visible tip of the cost iceberg. Procurement teams that make supplier selection decisions solely based on Unit Ex-Works (EXW) or Free on Board (FOB) quotations frequently find that customs duties, bunker adjustment factors (BAF), currency exchange premiums, demurrage fees, and pipeline carrying costs erode their anticipated margins.
A rigorous Total Landed Cost (TLC) model maps every direct and indirect financial touchpoint encountered as freight moves across sovereign borders, international waterways, and multimodal transshipment hubs.
Pipeline Inventory: The Cost of Frozen Working Capital
When evaluating low-cost country sourcing (e.g., Vietnam or India) versus domestic nearshoring (e.g., Mexico or domestic US manufacturing), transit time is often treated merely as a customer service lead-time metric. Mathematically, in-transit inventory represents locked capital that incurs carrying costs:
If an order of $500,000 spends 45 days in transit with an annual carrying cost of 22%, the in-transit financing cost is $13,561. This equals an additional $2.71 per unit on a 5,000-unit batch, frequently eliminating the nominal unit price discount offered by the overseas factory.
Frequently Asked Questions
What is the difference between FOB and EXW Incoterms?
Under EXW (Ex Works), the buyer bears all costs and risks from the seller's factory door, including origin export customs and terminal handling. Under FOB (Free on Board), the seller is legally responsible for loading the cargo on board the vessel and clearing export customs; the buyer only assumes freight, insurance, and import duties once loaded.
How is volumetric (dimensional) chargeable weight calculated?
Carriers bill by the greater of actual gross weight (kg) or volumetric weight. Volumetric weight equals (Length × Width × Height in cm) divided by an industry divisor—typically 5,000 cm³/kg for express air courier or 6,000 cm³/kg for commercial air cargo. In ocean shipping, 1 Cubic Meter (CBM) corresponds to 1,000 kg.
