Quotes for the same grade and same specification can vary widely. Common sources:

- Raw material source and nickel/molybdenum alloy costs; - Processing route (coil → cut-to-length → slitting → circle) and yield loss; - Surface grade (2B, BA, No.4, 8K) and the proportion of re-grinding; - Tolerance control: negative or positive tolerance carries different costs; - Packaging (VCI, wooden crate, pallet) and shipping method; - Payment terms (TT, LC, credit terms) and the implied cost of capital.

When comparing prices, ask suppliers to quote on a "like-for-like" basis: same standard, same surface, same tolerance, same packaging, same lead time—otherwise the prices are not comparable.
