What the route actually is
A production order, not a stock purchase: the fabric is knitted and dyed for you, so the minimum is a dye-bath minimum, not a handling minimum. That is why the route starts at several hundred pieces per colour.
Then the sequence: sample, approve, deposit, produce, inspect, ship, clear. Ten to thirteen weeks door to door if nothing slips, and something usually slips at the approval-to-deposit stage.
FOB versus DDP, and why the number looks different
FOB means the price stops at the port: you appoint the freight forwarder, you pay freight, you clear customs, you pay duty. DDP means the supplier delivers to your door with duty paid, and builds all of it into the unit price.
DDP is simpler and more expensive per piece; FOB is cheaper and requires you to become an importer for one shipment. Neither is better — but the two numbers are not comparable and should never be put in the same column.
The two numbers that decide the deal
Landed cost per shirt, and cash tied up before the first sale. A FOB price of $2.60 with 41.5% duty and $0.55 of freight lands at $4.23 — 63% above the number on the quote.
Cash is the other half: goods plus duty plus freight plus broker, all paid before you have sold a single shirt, and paid again if you reorder before the first order sells through.
What to verify, and when
Before the deposit: legal entity, bank name match, factory video, references. Before final payment: third-party inspection against the approved sample. Before the vessel sails: HS code and declared value.
Each of those belongs to a specific stage. Doing them all at the end is not diligence, it is a post-mortem.
Where this route stops being worth it
Below a few hundred pieces per colour, the dye-bath minimum makes it impossible. Above several thousand, it is clearly the cheapest route and worth the complexity.
In between sits the awkward middle — more than a case, less than a container — which is exactly where stock in the destination country earns its higher unit price.
