Salt insights: mesh sizes, K1–K3 grades and specifications

This section collects technical articles and reference pages that answer the questions salt buyers ask before sending an enquiry, such as how many millimetres Mesh 20 is and what separates K1 from K2.

Who this section is for

We write these pages for the people who set salt specifications and choose suppliers: procurement staff comparing quotations, QC teams checking a certificate of analysis (COA) when a shipment arrives, and importers who need to explain Indonesian salt terms to their own customers.

Indonesian salt trade terms often have no direct equivalent elsewhere. “Krosok” or “gosrok” means coarse salt harvested from evaporation pans, K1 to K3 are quality classes used by salt farmers and traders, and the “mesh” printed on a bag of fine salt does not always refer to the same sieve standard. The articles here explain these terms in technical language you can verify.

How we handle numbers

Every standard or regulatory figure in this section links to its source, for example the US standard sieve table for mesh-to-mm conversion and SNI 3556:2016 for iodized consumption salt in Indonesia. We do not publish general figures for Ventura’s own products (NaCl, moisture, insoluble matter, KIO3). Those values apply per batch and appear on the COA; until the data is released, pages show [COA] or [awaiting data].

Figures from the literature, such as the NaCl ranges for K1, K2 and K3, are labelled as a general industry description. They vary between sources and between harvest seasons. Use them for orientation, then set acceptance limits in your contract based on lot test results.

From reading to a purchase specification

If you already know what you need, send your specification through the quotation form. State the grade or mesh, the NaCl and moisture limits you work to, packaging, volume and destination. Overseas buyers can use the export enquiry form; buyers in Indonesia can use the domestic form.
