Scrap Pricing

The daily- or weekly-changing price list a yard applies to inbound and outbound loads — driven by mill demand, LME indices, and regional supply.

## How scrap pricing works

Scrap prices change daily for most nonferrous and weekly for ferrous. Inputs:

- **LME (London Metal Exchange)** for copper, aluminum, lead, zinc, nickel.
- **COMEX** futures for copper.
- **Platts / Metal Bulletin** indices for HMS, busheling.
- **AMM (American Metal Market)** for regional differentials.

## Pricing patterns

- **Cost-plus:** Index price minus a per-pound deduction.
- **Floor price:** Operator sets a manual floor that supersedes the index.
- **Spot:** Quoted per-load when index data is stale or volatile.
