The trim price was agreed, yet the settlement does not match — and usually the gap is not quantity but currency. Paper, plastic resin and some synthetic yarns are themselves priced in dollars, a renminbi cost base is then converted into a dollar invoice, and three exchange rates sit in between: quote date, production date and payment date. Whoever absorbs the difference is decided by the contract, and if the contract is silent, the seller absorbs it.

This guide covers how to choose the quoting currency, four ways to share exchange risk, how to write validity and the reference rate, the conversion cost carried by each payment method, and a clause list you can copy straight into a quotation.

Why the exchange clause belongs in the contract

A trim order typically runs 30 to 90 days from quotation to payment. Net margins in this industry sit in the single digits, so a three percent currency move can wipe out the profit on an entire order — and three percent within one quarter is not unusual. No clause means the seller silently absorbs all of it. A clause at least gives any dispute a basis and a formula, instead of a negotiation conducted on goodwill each time.

Choosing the quoting currency

Currency Where it fits The cost to know about
US dollar The default for Europe, the Americas, the Gulf and Latin America Most familiar to buyers; the seller carries conversion and exposure
Euro EU customers and annual framework agreements Easy price comparison; usually more volatile than the dollar
Renminbi Domestic buyers and some Southeast Asian customers No currency risk for the seller; the buyer converts and may ask for a discount
Buyer's local currency Markets where dollars are tight, such as Latin America or Türkiye Conversion loss and control risk are high; price it in or add clauses

Four ways to share exchange risk

  • Fixed price, short validity: the quote stands for 15 to 30 days and is reconfirmed after that. Simplest and most common, well suited to small and mid-sized orders.
  • Trigger band: fix a base rate and a band, commonly plus or minus two to three percent, and adjust the unit price proportionally beyond it. Suits contracts running six months or more.
  • Staged fixing: price a long order quarter by quarter or month by month, each tranche confirmed at the rate of the moment, so neither side has to forecast six months out.
  • Local-currency quote with a buffer: price in the buyer's currency with two to four percent built in for conversion and repatriation. The unit price looks higher than the dollar quote, but what lands is steadier.

Reference rate and fixing date: where arguments start

Three things must be spelled out: the source of the reference rate — the central parity published by China's foreign exchange trading centre, or a named bank's telegraphic transfer buying rate — the fixing date, chosen from quote date, contract date, shipment date or payment date and only one of them, and the number of decimal places. Most disputes are about which day counts, and shipment-date parity is far more workable than the phrase real-time rate.

Payment terms decide the conversion cost

A telegraphic transfer deposit with the balance against a copy of the bill of lading is the most common combination in trim exports, and the most controllable on cost. Letters of credit eat margin through bank charges and document requirements, and dollar clearing in the issuing bank's country can be delayed, so price in that time cost. Platform collection such as PayPal or Stripe carries higher fees and worse conversion on withdrawal — fine for samples and small orders, wrong for container loads of trims. Leaving one to three percent of financing cost out of a quote simply gives the profit away.

Linking to raw material: paper and plastic are dollar-anchored

Paper, PE and PP resin and some synthetic yarns are themselves quoted in dollars, so a renminbi cost base moves on two fronts at once: a favourable currency move can coincide with a resin increase and total cost still rises. Rather than the vague line that prices may be adjusted to market, attach a cost breakdown to the quotation showing the raw material share, the public index it follows and the review cycle, so both sides argue from the same sheet.

A clause list you can copy

Clause Suggested wording
Currency and trade term USD, FOB Shenzhen
Validity 30 days from quotation date
Reference rate CFETS central parity on the shipment date
Adjustment trigger Beyond plus or minus three percent of the base, price adjusted proportionally
Payment 30 percent telegraphic transfer deposit, balance against bill of lading copy
Raw material linkage Paper and PE indexed to published benchmarks, reviewed quarterly
One principle: a currency clause is not distrust, it puts uncertainty on the table. The side that writes it clearly is usually the one that wins longer payment terms.
