What is your sample policy for green-plum-concrete?
Top supports evaluation with 5-10 g samples (sometimes up to about 20 g for qualified buyers), drawn from current stock or a fresh batch, shipped with COA plus assay. Samples are usually charged at the sample-tier price (or free for strategic / qualified accounts) plus freight.
We recommend requesting the sample from the same lot you intend to purchase so the profile matches your production batch. Sample lead time is short (stock) or aligned with the next production window.
Tell Top your application and preferred grade and we will suggest a representative sample.
