Reported lead times cannot be considered as a warranty, but as an indication of average approximate lead times. Despite most orders are made quite fast, in 1-2 days, with transient times to most countries of 1-3 days, any longer lead times cannot justify making any claims, nor justify any compensation.

Some specialty high tech products, such as some conductive products are synthesized after orders are placed to extend their shelf life. Their lead time is longer (around 1-2 weeks or more) than the rest of the products, which are normally made to order and supplied quite fast after ordering. 

The same delay of several weeks in the lead times may happen to some recently developed products, such as some high performance powders for Selective Laser Sintering SLS printing of high quality functional polymers.
