What's the best way to track specialty chemicals pricing trends right now?

Honestly, secondary alone probably won't cut it right now — ICIS and Chemical Week are solid for published benchmarks, but prices are still moving fast enough that a quick round of supplier interviews (even 8-10) will tell you way more about real transaction prices vs. list prices. I'd layer both: use secondary to set context, then primary to validate what's actually happening at the contract level.
