How Skylark Exports selects, grades, checks, and packs industrial minerals, with the documents a shipment needs.
Material is selected, graded, checked, and packed before it ships. Each step below is the same work a buyer can ask about on the inquiry.
01
The mineral is chosen for the job the plant already runs: glass, foundry, a ceramic body, a coating, a refractory, or construction. The inquiry names that job. A typical range on a product page is a map of the grade family, not the lot you will receive.
02
Grain, chemistry, and moisture are checked against the limits you send. That might be mesh or AFS, iron, whiteness, alumina, or alkali. The current sheet is the number you compare. Nothing on this site is a certificate of analysis.
03
The lot is packed in the form the plant can receive. Typical export packing is 25 kg bags, 50 kg bags, 1 MT jumbo bags, or bulk. Which of those Skylark offers for a grade is confirmed on the inquiry.
04
The shipment is described with a certificate of analysis, a packing list, and an invoice for that lot. Those files travel with the shipment. They are not sample downloads here. The destination port is the one you name.
Three papers describe a shipment. They are written for that lot. They are not files you can download from these pages.
The COA is the lab result for the lot, against the limits you asked for. A table of typical ranges is not a substitute, and this site does not host a sample COA.
The packing list says how that lot was bagged or loaded: bag size, count, and weight. It matches the packing named on the inquiry.
The commercial invoice identifies the shipment. Together with the COA and the packing list, it is what a buyer checks before the material is accepted.

Each mineral page carries the typical range for that grade family and the packing to confirm. The export page follows the same path from the inquiry side.
The sheet for the lot is written against those limits, not against a typical range on this site.
