Long-lead material has to be bought before the order that consumes it. Who carries that exposure — and for how long — belongs in writing.
A frame agreement with rolling forecasts asks the supplier to buy material against numbers that are, by definition, provisional. That is workable and normal. What is not workable is leaving unsaid what happens when the forecast changes and the material is already on the shelf.
The clause needs three things: a horizon, a quantity basis and an exit. The horizon says how far ahead material may be committed — often the longest lead time in the bill of materials. The quantity basis says how much: usually the firm window plus an agreed share of the forecast. The exit says what happens to committed material if the program stops, and at what price.
Minimum order quantities deserve their own sentence. A component with an MOQ of five thousand pieces bought for an annual demand of eight hundred is not a supply decision, it is a four-year commitment. We flag those at quotation rather than discovering them at the first re-order.
None of this is adversarial. It is the difference between a partnership that survives a demand drop and one that ends in a spreadsheet argument. The supplier who raises material liability early is not being difficult; they are telling you they intend to be there in three years.
