Product Range and Specialties of Tangshan Keshou Advanced Ceramic Manufacture Co., Ltd.

The eight listed items are all alumina‑based ceramic components. Product types include crucibles for melt containment, thermocouple tubes for temperature sensing, liner bricks for wear protection, straight tubes and pipes for fluid conveyance, insulation tubes for thermal barriers, furnace process tubes, bushing tubes for instrument mounting, and porous foam filters for particulate capture. Each entry is presented with a descriptive name but without detailed dimensional data.

In the broader ceramics industry, alumina tubes are typically supplied in purity grades of 99.5 % to 99.99 % Al₂O₃, with standard outer diameters ranging from 6 mm to 200 mm and wall thicknesses from 0.5 mm to 10 mm. Common specifications include tolerance of ±0.1 mm, thermal shock resistance tested according to ASTM C373, and compressive strength above 300 MPa. Foam filters are usually produced with pore sizes between 0.5 mm and 5 mm and are graded by porosity percentage. Buyers often request material test reports that confirm chemical composition, density, and mechanical properties.

Trade and Export Information - Tangshan Keshou Advanced Ceramic Manufacture Co., Ltd.

China is among the world’s largest exporters of advanced alumina ceramics, and shipments of ceramic tubes fall under HS Chapter 69, specifically heading 6902 for “Ceramic tubes and pipes.” Typical destination regions include Southeast Asia, Europe, and North America, where the products serve the electronics, aerospace, and chemical processing sectors. Importers usually require certificates such as ISO 9001 for quality management and may request test reports conforming to ASTM or ISO standards for purity, dimensional tolerance, and thermal performance. Packaging for ceramic tubes commonly involves double‑wall wooden crates, polyethylene foam inserts, and palletization for 20‑ft or 40‑ft containers, with Incoterms like FOB Tianjin or CIF Shanghai prevailing in many transactions.

Export controls in China mandate compliance with the Export Control Law for dual‑use items, and buyers should verify that the supplier holds any necessary export licenses. Freight forwarders often advise using moisture‑resistant liners inside crates to prevent damage during sea transport. Inspection agencies such as SGS or Bureau Veritas are frequently engaged to perform pre‑shipment verification against the buyer’s specification sheet.

Sourcing from Tangshan Keshou Advanced Ceramic Manufacture Co., Ltd. - Buyer Guidance

When sourcing alumina ceramic components, buyers should request a full material test report (MTR) that details Al₂O₃ purity, bulk density, and mechanical strength. Dimensional drawings or CAD files should be compared with the supplier’s standard tube dimensions to confirm compatibility with existing equipment. It is advisable to obtain a sample batch for thermal‑shock testing under the buyer’s actual operating conditions before confirming a larger order.

Buyers should also confirm that the supplier can provide certifications such as ISO 9001 or ISO 14001, and ask for a declaration of conformity with relevant ASTM or ISO standards. Verification of export licenses and compliance with the destination country’s import regulations (e.g., customs classification under HS 6902) helps avoid clearance delays. Clarifying packaging details - crate size, cushioning material, and labeling - ensures safe handling throughout the logistics chain.

What material are the tubes and crucibles listed by Tangshan Keshou made from?

All eight catalogue items are described as alumina (Al₂O₃) ceramic components, which is a common high‑temperature material in the industry.

How many different alumina products does the supplier list?

The supplier lists eight distinct alumina products, ranging from crucibles and thermocouple tubes to foam filters and liner bricks.

Which HS code is typically used for alumina ceramic tubes exported from China?

Ceramic tubes and pipes are generally classified under HS heading 6902, which covers “Ceramic tubes and pipes.”

What purity level is standard for high‑purity alumina ceramics?

Industry standards for high‑purity alumina usually require 99.5 % to 99.99 % Al₂O₃ content, and the catalogue mentions a 99 % high‑purity product.

What certifications should a buyer request for these ceramic products?

Buyers commonly request ISO 9001 quality‑management certification, material test reports, and compliance documents referencing ASTM C373 or ISO 6475 for thermal‑shock performance.

What packaging method is typical for shipping alumina ceramic tubes?

Alumina tubes are often packed in double‑wall wooden crates with polyethylene foam inserts, palletized for 20‑ft or 40‑ft containers to protect against breakage.

Which industries typically import alumina ceramic tubes from China?

Key importers include the electronics, aerospace, chemical processing, and advanced manufacturing sectors that need high‑temperature resistance and dimensional stability.

What documentation is needed to clear customs for these ceramic items?

Customs clearance usually requires a commercial invoice, packing list, certificate of origin, and the HS classification (6902). Additional test reports may be requested by the importing authority.
