Yarn Price Volatility: How Buyers Lock Knitwear Costs

Short answer: You cannot lock yarn cost indefinitely, and any factory that promises a fixed price for six months is either pricing that risk into your margin or planning to renegotiate with you later. What you can do: get a written price validity window (30 days standard, 60 negotiable), book yarn against a deposit at the start of that window, and have the quote split into yarn and conversion so a fibre move does not quietly become a margin move. On a 3,000-piece sweater programme, booking yarn six weeks early typically saves $0.60–$1.10 a piece versus waiting for the PO.

Every buyer learns this the same way: a second quote comes back 12% higher and the explanation is "cotton went up". Sometimes true, sometimes a factory that never booked anything and is passing on a spot price. You cannot tell the difference unless the quote separates yarn from conversion — which is the first thing to ask for.

Four Ways to Lock Cost, With the Honest Trade-Off

Our recommendation, plainly: use option 3 always, option 2 always, and option 1 on styles with a reorder probability above about 60%. For a genuinely new style with no sales data, do not book yarn — volatility is cheaper than owning 500 kg of a colour nobody wanted.

What a Good Price Clause Says

When to Book: the Knitwear Calendar

For autumn/winter delivery to Europe or North America, the yarn decision happens earlier than most buyers plan for:

The buyer who books yarn in February and the buyer who signs a PO in May are buying the same sweater from the same mill at prices that differ by more than the whole margin. Timing is a costing decision.

Conclusion

Volatility is not a problem you solve, it is a risk you allocate. The factory will hold it if you let them, and they will price it in. Book yarn where you have confidence, demand a split quote and a dated validity everywhere else, and treat the production calendar as part of costing.
