What are intermediate materials?

An intermediate material is a part you make yourself and then use in your own product. If that part qualifies on its own, it counts as originating when it goes into the product, even though it was made with imported inputs.

An example

You cast an engine block from imported aluminium, and the block meets its own rule. When the block goes into your engine it counts as originating, and the imported aluminium inside it no longer counts against the engine.

Why it helps

It's sometimes called roll-up or absorption. Once a part qualifies, the imported content inside it drops out of the sums for anything you make from it. Some agreements let you choose which parts to treat this way.
