How Long Should a Magnet Supplier’s Quote Really Stay Valid?

Rare earth material prices have been moving quite a bit lately. If you‘re on the sourcing side of things, you‘ve probably had a few conversations lately about how to handle it.

One approach is locking in a long-term agreement with a fixed price. The upside is predictability—you know what your magnet costs will look like for the next several months, which makes quoting your own projects a bit easier. The trade-off is that if market prices drop, you might find yourself above the current rate.

The other path is buying spot, following the market as it moves. That gives you the flexibility to benefit when prices soften, but it also means you‘re exposed when they climb. And with something like sintered neodymium magnets, where raw material can be a significant portion of the cost, those swings tend to show up directly in the pricing.

Then there‘s the question of how long a supplier‘s quote should stay valid. For products tied closely to rare earths, a 30-day quote used to feel standard. These days, some suppliers are offering 15 days, or even 5 to 10 days when volatility picks up. It‘s not necessarily a sign of anything—just a reflection of how quickly their own costs can change.

There‘s no single right answer here. Some teams prefer the stability of a long-term agreement, others like staying nimble. It mostly comes down to what fits your own project timelines and how much risk you‘re comfortable holding.
