Quartz lumps are natural mineral aggregates composed almost entirely of silicon dioxide (SiO2). ANT Traders supplies high‑purity quartz with SiO2 content ranging from 99.0 % to 99.9 %. Individual lumps measure between 10 mm and 300 mm in diameter. The product is shipped in jumbo bags or as loose bulk, suitable for container loading.
In the mineral market, quartz of this purity is classified as industrial‑grade silica used for glass and ceramic melt streams. Typical industry specifications call for a hardness of 7 on the Mohs scale and a bulk density around 2.65 t/m³, which align with the material supplied by ANT Traders. Standard moisture content for bulk quartz is below 0.5 % to prevent agglomeration during handling. The supplier indicates that the lumps are free of visible foreign matter, matching common quality expectations for ferro‑alloy feedstock.
Buyers such as glass manufacturers, foundries and silicon producers source these lumps for melt stability and impurity control. Trade is normally conducted on FOB or CIF terms, with minimum order volumes negotiated directly with the supplier. Prospective importers should confirm packaging size, exact purity grade and any required certification before finalising purchase.

Before placing an order, verify that the supplier can provide a recent certificate of analysis confirming the SiO2 purity and that the lumps meet your required size distribution. Request a sample or a pilot shipment if possible, and check that the packaging method aligns with your warehouse handling procedures. These steps reduce the risk of receiving material that does not meet production specifications.
Logistics for quartz lumps are usually arranged on FOB or CIF terms. Confirm the incoterm that best fits your supply chain, and ask the supplier for an estimated lead time based on the requested quantity. Payment terms are typically negotiated per transaction; common arrangements include a letter of credit at sight or a 30‑day open account after shipment documents are verified.
Quality control for bulk quartz commonly includes moisture testing, purity analysis by X‑ray fluorescence and visual inspection for foreign matter. Arrange an independent third‑party inspection at the loading port if you require additional assurance. Ensure that the supplier can furnish the necessary documentation, such as a material safety data sheet and any relevant export certificates, before the goods are dispatched.
