Triangular Trade Process Flowchart: How Orders, Shipping, Payment and Documents Flow (8 Steps)

Triangular Trade Flowchart

Orders and payments: buyer ⇄ trader ⇄ supplier | Goods: supplier → buyer (direct shipment)

The 8 Steps of Triangular Trade

Step 1: The buyer requests a quote and orders

The overseas customer asks the trader for a quote, confirms specifications, quantity, lead time and destination port, and issues a purchase order.

Step 2: The trader buys from a third-country supplier

The trader finds suitable factories, compares quotes, confirms samples and places a purchase order with the supplier. For how to find and evaluate suppliers, see How to Find and Evaluate Overseas Suppliers.

Step 3: Sign back-to-back contracts

Triangular trade involves at least two contracts:

• Sales contract: between the trader and the buyer
• Purchase contract: between the trader and the supplier

Product, specifications, quantity, lead time, packaging and Incoterms must match in both contracts. For example, if you quote CIF to the buyer, you must agree with the supplier who books freight and who buys insurance, or there will be a gap in responsibility. The 11 Incoterms 2020 rules are summarized in How to Import Bubble Tea Ingredients from Taiwan and Trade Terms & Process.

Step 4: Arrange payment terms

Typically the buyer pays the trader and the trader pays the supplier, by letter of credit (L/C) or telegraphic transfer (T/T). The trader must plan the timing gap so it isn’t paying the supplier before receiving the buyer’s payment.

Step 5: Production and inspection

The trader tracks production and arranges a pre-shipment inspection to confirm quality, quantity, packaging and labeling meet the contract. See Factory Audit vs Product Inspection.

Step 6: The supplier ships directly to the buyer

Goods ship from the supplier’s country straight to the buyer’s country. How the shipper and consignee are filled in on the bill of lading affects whether supplier and buyer can see each other’s details; if changes are needed, see how switch bills of lading work and their limits.

Step 7: Documents and customs clearance

The trader delivers the full set of shipping documents to the buyer for clearance at destination. Cargo description, quantity, weight and container numbers must match the actual goods.

Step 8: Settlement and tax filing

The buyer pays the trader and the trader pays the supplier. For a Taiwanese trader, business tax treatment depends on whether the deal is booked as commission (margin) or as purchases and sales (full amounts); see Triangular Trade and Taiwan Business Tax.

4 Common Risks in Triangular Trade

1. Terms that don’t match: mismatched lead times, specs or trade terms leave the trader holding the liability.
2. Payment timing gaps: paying the supplier before the buyer pays creates cash flow pressure.
3. Documents that don’t match the goods: mismatched description, quantity or weight can delay clearance or lead to L/C refusal.
4. Origin and compliance issues: foreign goods may not be marked Made in Taiwan, and transshipment cannot be used to evade duties; see Rules of Origin.
