Is longan-concrete seasonal, and how does that affect availability?

Availability is governed by processing capacity and raw-material scheduling rather than a single harvest window. Top keeps buffer stock of standard grades and contracts raw material volume; for large or steady volumes we recommend an LTA to reserve processing slots and stabilize price.

We communicate raw-material market conditions on each quotation.
