About Zian - Quartz Supplier in United States

Based in the United States, Zian currently lists seven active mineral products for international trade. The supplier’s catalogue spans quartz, silica sand, iron ore, manganese ore, calcium carbonate, phosphates and talc, covering a range of industrial raw materials used in glass making, metallurgy, chemicals and construction. Each product is identified with a specific HS‑code family and material specification, allowing buyers to match trade documentation precisely. The active product count of seven reflects the breadth of Zian’s offering within the mineral sector, without implying any additional services or certifications beyond those stated.

The catalogue details Quartz (HS 2506.10, Silicon Dioxide SiO2 99.0‑99.9 %), Sand glass (HS 2505.10, Quartz Silica Sand SiO2 99 %+), Iron ore (HS 2601.11, Hematite Fe2O3), Manganese (HS 2602.00, Mn content 44‑48 %), Calcium carbonate (HS 2836.50, CaCO3 98‑99 %+), Phosphates (no HS code provided), and Talc (HS 2526.20, Magnesium Silicate Hydroxide Mg3Si4O10(OH)2). The HS codes correspond to the internationally recognised tariff headings for each mineral, facilitating customs clearance and statistical reporting. Zian’s listing does not include any claim of certification, but the material grades are explicitly stated, which is typical for bulk mineral exporters.

Product Range and Specialties of Zian

Zian’s product list includes high‑purity quartz (99‑99.9 % SiO2) suitable for semiconductor and optical applications, as well as glass‑grade silica sand (≥99 % SiO2) commonly used in container and flat‑glass production. In the iron ore segment, the hematite specification aligns with typical Fe content of 60‑65 % required for blast‑furnace steelmaking, while the manganese ore grade of 44‑48 % Mn matches the range preferred for ferro‑manganese alloys. Calcium carbonate at 98‑99 % purity is standard for paper coating, plastics filler and agro‑chemical feedstock, and talc with the Mg3Si4O10(OH)2 composition is a common grade for ceramics, cosmetics and paint fillers. Industry practice also distinguishes these minerals by particle size distribution, moisture content and bulk density, parameters that buyers usually verify through test reports.

Trade and Export Information - Zian

Exporters of quartz, silica sand, iron ore, manganese, calcium carbonate and talc from the United States typically ship to North America, the European Union and East Asia, where these raw materials support glass factories, steel mills, chemical plants and construction sectors. The HS‑code families 2506, 2505, 2601, 2602, 2836 and 2526 are standard across customs systems, and shipments are often subject to quality inspections such as SGS or Bureau Veritas audits, especially for buyers requiring ISO‑9001 compliance. Bulk shipments are normally packed in 20‑ft or 40‑ft containers using woven polypropylene bags (e.g., 20 t per bag) or in open‑top bulk carriers for larger volumes, with Incoterms like CIF or FOB commonly applied. United States mineral exporters are accustomed to providing assay certificates, material safety data sheets (MSDS) and, when requested, third‑party laboratory reports to satisfy import regulations in destination countries.

Sourcing from Zian - Buyer Guidance

When sourcing from Zian, buyers should request a recent assay or test report that confirms the purity percentages listed for each mineral, as well as a certificate of origin to satisfy customs valuation. Verification of industry‑standard certifications - such as ISO 9001 quality management, SGS inspection reports, and compliance with REACH or RoHS where applicable - helps mitigate risk, even though Zian does not explicitly hold these certifications in the provided data. Buyers are also advised to confirm packaging details (e.g., 20 t bulk bags, moisture limits below 1 %) and to negotiate lead times, which typically range from 30 to 45 days after order confirmation for bulk mineral shipments.

What HS code is used for Zian’s quartz product?

Zian lists quartz under HS code 2506.10, which falls within the chapter for natural quartz and related mineral products.

What purity level does Zian specify for its quartz?

The quartz supplied by Zian contains silicon dioxide (SiO2) at a purity range of 99.0‑99.9 %.

Which certification documents should a buyer request for Zian’s minerals?

Buyers should ask for a recent assay or laboratory test report, a certificate of origin, and, if required by the destination market, ISO 9001 or SGS inspection certificates.

What packaging format is typical for Zian’s bulk minerals?

Typical packaging includes woven polypropylene bulk bags of 20 tonnes, loaded into 20‑ft or 40‑ft containers, or in bulk for open‑top shipping.

What are the usual lead times for orders from Zian?

Lead times generally range from 30 to 45 days after order confirmation, depending on product availability and shipping arrangements.

Is there a minimum order quantity for Zian’s iron ore?

While Zian does not publish a fixed MOQ, bulk mineral exporters commonly set a minimum of 20 metric tonnes per shipment to justify container loading.

How can a buyer obtain a sample of Zian’s silica sand?

Buyers can request a small sample (e.g., 5‑10 kg) by providing shipping details; Zian will dispatch the sample in a sealed bag for laboratory verification.

Which markets typically import the minerals listed by Zian?

Typical import markets include the United States, Canada, the European Union, Japan, South Korea and China, where the minerals support glass production, steelmaking, chemical processing and construction industries.
