Quick answer: An FX clause fixes the gap between quote date and payment date — a 7.10 base, a 30-day validity, and a ±2% band split 50/50 once breached.

1. Why an FX Clause Belongs in a Case Quote
A 580 mm rotomoulded case quotes at USD 86 and costs 540 CNY to build; at 7.10 that leaves 70.6 CNY of margin. Pay 90 days later at 6.96 and the same case returns 12 CNY less, an 18% cut.
The clause is an allocation, not a forecast: validity, production, and payment span 90 to 150 days, and the unclaimed stretch lands on the seller's ledger.
Exposure follows cost structure. 62% of a body is polymer, hardware, and mould amortisation, priced in CNY while quotes and letters of credit run in USD, so at USD 12 million of shipments a year a 2% move is USD 240,000.
2. Four Wordings: From a 30-Day Lock to the Bill of Lading Rate
All four work; they differ in what the base is, how long it holds, and who pays when it breaks.
Fixed rate with a validity window, 30 or 60 days. The quote locks 7.10 and day 31 brings a new base. The buyer can budget and the seller skips monthly reconciliation, at the cost of re-quoting late orders. Samples and shipments under USD 50,000 fit best.
A no-adjustment band. Base 7.12, a band of ±1.5%, no repricing inside it, a full-order adjustment once the rate leaves. Two checks a year cover the administration.
Shared loss beyond a trigger. Trigger at ±2%, excess split 50/50, capped at ±6% before reopening talks or shipping in lots.
Full float against the bill of lading rate. Unit price = base price × bill of lading parity ÷ 7.10, with the source and fixing date written in. Clean arithmetic, buyer carries the move.
Two-way is what gets signed. A clause that tops up when the CNY strengthens but never credits when it weakens will not clear review. At 6.96 the seller invoices a supplement; at 7.24 the buyer takes a credit.
| Wording | Base | Validity or trigger | Who carries the excess | Fits |
|---|---|---|---|---|
| Fixed rate plus window | Quote-day parity 7.10 | 30 or 60 days | Late orders re-quoted | Samples, under USD 50,000 |
| No-adjustment band | 7.12 | Inside ±1.5% | Full-order shift outside | 30 to 60 day terms |
| Shared beyond trigger | 7.10 | ±2%, 50/50 | Split, capped at ±6% | 90 to 120 day terms |
| Full float | Bill of lading parity | Every shipment | Buyer | Annual framework |
3. A 2% Trigger or a 3% One
Triggers are measured, not chosen. Daily USD/CNY movement runs 0.1% to 0.3%; drift reaches about 1.8% over 60 days, 2.4% over 90, 2.9% over 120. So 30 to 60 day terms take ±2% and anything past 90 days takes ±3%. Tighter than that and routine noise trips the clause, costing more in paperwork than the difference is worth.
Trigger counts convert into hours. At 40 shipments a year of USD 40,000 each, ±1% fires 26 times, ±2% fires 11, ±3% fires 6. One reconciliation takes three signatures and two days, so lifting the trigger from 1% to 2% saves about 30 hours and costs at most USD 400 of extra exposure per shipment.
The cap is easier to forget than the trigger. A clause that fires but never stops will swallow an order in a one-way market. Put the ceiling at ±6% to ±8%, where it converts into a renegotiation: a new price within 10 working days, unstarted lots cancellable.
| Payment term | Suggested trigger | Split | Maximum self-borne on USD 40,000 |
|---|---|---|---|
| 30 days | ±1.5% | Seller carries all | USD 600 |
| 60 days | ±2% | 50/50 | USD 400 |
| 90 days | ±2.5% | 50/50 | USD 500 |
| 120 days | ±3% | 60/40 to the seller | USD 720 |
4. Currency, Conversion Basis, and L/C Terms on Top
When quote and cost currencies differ, the conversion basis causes more disputes than the clause. On USD 40,000, the spot buying rate returns 852 CNY less than central parity and the cash buying rate 2,272 CNY less.
Name the source in the clause: the USD/CNY central parity published at 9:15 each working day by the China Foreign Exchange Trade System under authorisation from the People's Bank of China.
A letter of credit stretches the term again: a 90-day usance L/C runs 100 to 110 days from issuance to cash. Fix the rate on the issuance date, not the negotiation date, since presentation speed is something each side can bend. Where the amount is fixed at USD 40,000, issue the adjustment as a separate price annex and reference it under field 47A.
Past 90 days, price the funding cost in at 0.15% a month, about USD 0.40 on a USD 86 case at 90 days and USD 0.50 at 120, rather than argue at settlement.
Three model clauses to adapt:
- Model 1: The unit price is based on the USD/CNY central parity of 7.10 published on 2 March 2026, valid 30 days, after which it is re-quoted.
- Model 2: A settlement parity within ±2% of the base, inclusive, triggers no adjustment; any excess is shared 50/50, capped at 6% of contract value per shipment.
- Model 3: If parity moves more than 8% from the base, either party may call a renegotiation within 10 working days, with lots in production invoiced at the original price.
Conclusion
An FX clause is a table, not a promise. Four checks decide whether it holds: the base is the 9:15 parity with its source named, validity runs 30 days and lapses into a re-quote, the trigger matches the term at ±2% for 60 days and ±3% beyond 90, and the cap sits at ±6% before talks reopen. Get those right and a USD 86 case keeps its CNY margin from quote to payment.
