New Shipping time filter and fact label per product
Commercially available products will feature shipping times based on vendor information. In order to simplify filtering, the labelling has been normalized based on Tier time definitions (Tier 1= Up to 5 days, Tier 2= Up to 10 days, Tier 3= Up to 4 weeks, Tier 4= Up to 12 weeks, Tier 5= Please contact supplier). You can see the new grouping in the filter [A] and within the product availability table per supplier [B] so its easier for you to determine when a chemical will be available to use.
