# Letter of Credit (L/C) Payment Guide
As your Canton Fair orders scale from $10,000 to $500,000, sending a standard T/T bank wire becomes an unacceptable risk. You cannot wire half a million dollars to a factory in China and simply "hope" they put the goods on a ship.
For massive, enterprise-level transactions, global trade relies on the **Letter of Credit (L/C)**. It is a financial instrument where your bank guarantees payment to the factory's bank, but *only* if the factory proves they shipped exactly what was ordered.
> **💡 Withyou Trip Expert Verdict:**
> "The deadliest trap when using an L/C is the **'Discrepancy Rejection'**. An L/C is not governed by common sense; it is governed by brutal, literal paperwork. If your L/C says the goods must be shipped in 'Blue Boxes', and the factory's shipping document says 'Dark Blue Boxes', the bank will declare a discrepancy and refuse to pay the factory. The container will be locked at the port, racking up thousands in demurrage fees. You MUST ensure the factory has a world-class export documentation clerk."
## 1. The B2B Payment Risk Matrix
| Payment Method | Risk to Buyer | Risk to Factory | Best Use Case |
| :--- | :--- | :--- | :--- |
| **100% T/T Upfront** | 🔴 Extreme (You could lose everything). | Zero. | Never use this. Only for tiny sample orders. |
| **30% Deposit / 70% against B/L**| Medium (Factory could ship garbage). | Medium (You could refuse to pay balance).| ⭐⭐⭐⭐⭐ **Standard for 90% of SME orders ($10k - $100k).** |
| **Letter of Credit (L/C)** | ⭐⭐⭐⭐⭐ **Bulletproof.** | Low (Bank guarantees payment). | Massive orders ($200k+). Expensive bank fees. |
| **O/A (Open Account)** | Zero (You pay 60 days after delivery). | 🔴 Extreme. | Factory must trust you implicitly. Requires Sinosure backing. |
## 2. How the Irrevocable L/C Works
An L/C removes trust from the equation and replaces it with banking logic.
* **Step 1:** You go to your bank (e.g., Chase) and open an L/C in favor of the Chinese factory. You deposit the $500,000 with Chase.
* **Step 2:** Chase sends the L/C to the factory's bank (e.g., Bank of China).
* **Step 3:** The L/C states: *"We will release the $500,000 to you ONLY if you present a clean Bill of Lading, a flawless SGS Inspection Certificate, and a Commercial Invoice matching the exact terms, by October 1st."*
* **Step 4:** The factory produces the goods, ships them, and hands the paperwork to the Bank of China. The banks review the paper. If it matches perfectly, the money is released. If it doesn't, the money is frozen.
## 3. The "At Sight" vs. "Usance" L/C
You can use an L/C to forcefully negotiate better cash flow.
* **L/C At Sight:** This means the bank pays the factory the moment the correct paperwork is presented. This is the most common.
* **Usance L/C (e.g., 60 Days):** This is a massive power move. The L/C states the bank will pay the factory 60 days *after* the paperwork is presented. This means the goods will arrive in your warehouse, you can sell them, and generate the revenue before the bank officially transfers the cash to the factory.
## ❓ Frequently Asked Questions (FAQ)
**Q: Why do Chinese factories hate accepting L/Cs for small orders?**
A: **The bank fees and the paperwork nightmare.** Opening an L/C costs thousands of dollars in banking fees on both sides. Furthermore, small Chinese factories often lack sophisticated financial clerks. They are terrified of making a typo on the Bill of Lading, triggering a discrepancy, and having their payment frozen by a Western bank for 3 months. Factories will usually aggressively refuse an L/C unless the order is well over $100,000.
