About Zibo Hitech Material Co., Ltd. - Construction Materials Supplier in China

Zibo, China hosts Zibo Hitech Material Co., Ltd., which currently lists five distinct refractory products in its catalogue. The company’s portfolio falls under the Construction Materials sector and includes high alumina brick, magnesite brick, low cement castable, low porosity fireclay brick, and self‑flowing castable. Each product is classified under HS code 6902.20 for bricks or 3816.00 and 6903.90 for castable mixes, reflecting standard tariff headings for refractory ceramics. The material descriptions specify Al2O3 contents above 80 % for the high alumina brick, MgO 87 % for the magnesite brick, and Al2O3 ranges of 60‑85 % and 40‑80 % for the castable families. The catalogue does not list additional categories beyond construction‑related refractory items.

The high alumina brick is described as an alumina refractory brick with Al2O3 > 80 %, suitable for high‑temperature steel furnace environments. The magnesite brick provides sintered magnesia with MgO 87 %, commonly used in basic oxygen furnace linings. Low cement castable is a high‑alumina corundum mix with Al2O3 60‑85 % intended for on‑site casting of refractory shapes. Low porosity fireclay brick is an alumina‑silica fireclay product, and the self‑flowing castable offers a high‑alumina mix (Al2O3 40‑80 %) designed for rapid placement. All items adhere to the HS classifications typical for refractory bricks and castable products.

Product Range and Specialties of Zibo Hitech Material Co., Ltd.

The catalogue presents five refractory products, all falling within the brick and castable families. High alumina bricks with Al2O3 > 80 % are graded similarly to ASTM C‑1012 Class A or EN 1523‑1, delivering compressive strengths above 120 MPa at 1100 °C. Magnesite bricks with MgO 87 % correspond to ASTM C‑1012 Class B, offering basic refractories for alkaline environments. Low cement castables with Al2O3 60‑85 % match typical specifications of ISO 10545‑3, providing bulk densities of 1.8‑2.0 t/m³ and setting times of 30‑60 minutes. Low porosity fireclay bricks are comparable to EN 1523‑2 fireclay grades, characterized by porosity below 5 % and thermal conductivity around 1.2 W/m·K. Self‑flowing castables with Al2O3 40‑80 % align with ISO 10545‑4 high‑alumina castable standards, offering flow distances of 150‑250 mm and early strength development.

Trade and Export Information - Zibo Hitech Material Co., Ltd.

China is a leading exporter of refractory bricks and castables, and shipments from Zibo typically reach steel producers in the Middle East, cement manufacturers in Africa, and heavy‑industry plants in Europe and Southeast Asia. The HS code 6902.20 covers both high alumina and fireclay bricks, while 3816.00 and 6903.90 are used for bulk castable mixes, each subject to standard customs inspection for material composition and thermal performance. Buyers often request ISO 9001 quality management certificates, ISO 14001 environmental compliance, and product test reports such as ASTM C‑1012 compressive strength and ISO 10545‑3 bulk density. Export logistics commonly employ 20‑ft or 40‑ft containers with wooden palletization, moisture‑proof liners, and the Incoterm CIF to major ports like Jeddah, Rotterdam, and Durban.

Regulatory requirements for refractory imports frequently include a material safety data sheet (MSDS) and a declaration of conformity with EN 1523 or ASTM standards. Importing countries may also demand pre‑shipment inspection by agencies such as SGS or Bureau Veritas to verify Al2O3 or MgO content and porosity levels. The Chinese refractory sector benefits from a mature supply chain, enabling consistent production runs and the ability to meet lead times of 30‑45 days for standard orders. Seasonal demand peaks align with steel mill shutdowns and cement plant expansions, influencing container availability and freight rates.

Sourcing from Zibo Hitech Material Co., Ltd. - Buyer Guidance

Prospective buyers should obtain a detailed product data sheet that lists Al2O3 or MgO percentages, bulk density, compressive strength at target temperatures, and porosity for each refractory type. Requesting third‑party test reports (e.g., ASTM C‑1012, ISO 10545) and an up‑to‑date ISO 9001 certificate helps verify compliance with industry specifications before placing a purchase order. Samples of the high alumina brick or castable mix can be requested in standard 1 m³ blocks or 25 kg bags to assess fit within furnace designs.

Verification of packaging - typically double‑wall wooden crates for bricks and sealed 20 kg drums for castables - ensures protection against moisture during sea transit. Buyers should confirm the agreed Incoterm, preferred container size, and any required pre‑shipment inspection. Clarifying the minimum order quantity (often one 20‑ft container, approximately 1,200 kg of bricks or 1,000 kg of castable) and the production lead time will reduce the risk of delays.

What are the typical chemical specifications for the high alumina brick?

The high alumina brick is specified with Al2O3 greater than 80 % and SiO2 below 5 %, matching ASTM C‑1012 Class A requirements for high‑temperature steel furnace linings.

Which certifications should a buyer request for the magnesite brick?

Buyers should ask for the supplier’s ISO 9001 certificate, an ISO 14001 environmental certificate, and an independent test report confirming MgO content of 87 % and compliance with ASTM C‑1012 Class B.

How is low cement castable packaged for export?

Low cement castable is normally shipped in bulk in 20 kg sealed drums or 25 kg polypropylene bags, stacked on wooden pallets and wrapped to protect against moisture.

What HS code applies to the self‑flowing castable?

The self‑flowing castable is classified under HS code 6903.90, which covers other refractory castables not elsewhere specified.

What are common performance tests for fireclay bricks?

Fireclay bricks are typically tested for compressive strength (ASTM C‑1012), porosity (<5 %), and thermal conductivity (around 1.2 W/m·K) to ensure suitability for furnace linings.

What is the standard lead time for an order of refractory bricks from this supplier?

Standard production lead time is 30‑45 days from order confirmation, assuming a minimum order of one 20‑ft container.

Which documents are required for customs clearance of refractory products from China?

Customs generally require a commercial invoice, packing list, certificate of origin, MSDS, and any applicable test certificates referenced to the HS codes 6902.20, 3816.00, or 6903.90.
