Each item is described with a specific HS code that reflects its refractory or ceramic nature.
The firm reports an annual output of more than 80 000 m³ of high‑temperature calcium silicate products, serving sectors such as metallurgy, glass, cement, petrochemical and non‑ferrous metal processing. Production is carried out at a facility in Sishui County, Jining City, within a 108 000 m² plant that hosts multiple production lines for calcium silicate series items. The company’s patented technology and engineering services focus on thermal insulation plates and related applications, aligning its product mix with the listed ten catalogue entries.
Product Range and Specialties of Laizhou Mingfa Thermal Insulation Material Co., Ltd
The catalogue covers a spectrum of calcium silicate insulation solutions: standard panels for furnace linings, graphite‑reinforced boards for high‑temperature environments, fire‑proof waterproof sheets, and non‑asbestos construction boards. In the industry, such boards typically have a bulk density of 0.30‑0.50 g/cm³, compressive strength between 5 and 15 MPa, and thermal conductivity of 0.09‑0.12 W/m·K, allowing safe operation up to 1 100 °C. Common grades are designated by HS‑code families - 6808 for general calcium silicate boards, 6810 for refractory plates, 6806 for graphite‑enhanced variants, 6903 for other ceramic products, and 6815 for specialized refractory linings. Buyers also look for fire‑rating classifications such as EN 13501‑1 A1 and compliance with standards like EN 13162 or ASTM C578.
Trade and Export Information - Laizhou Mingfa Thermal Insulation Material Co., Ltd
China is a leading exporter of calcium silicate insulation boards, with Europe, the Middle East and Southeast Asia representing the largest import markets for high‑temperature refractory products. HS codes 6808, 6810, 6806, 6903 and 6815 are routinely inspected under customs regimes that may require certificates of conformity to EN 13162 (EU) or ASTM C578 (US). Typical buyer requirements include ISO 9001 quality‑management certification, third‑party test reports (e.g., SGS, Intertek) and compliance with local building‑code fire‑rating standards. Products are usually palletised, wrapped in moisture‑proof film and loaded into 20‑ft or 40‑ft containers, with common Incoterms such as FOB Chinese ports or CIF to destination ports. Chinese export policy for refractory materials emphasizes consistent product dimensions, moisture control (<0.5 %) and proper labeling of HS codes to facilitate smooth customs clearance.
Sourcing from Laizhou Mingfa Thermal Insulation Material Co., Ltd - Buyer Guidance
When sourcing calcium silicate boards, buyers should request a detailed data sheet that lists thermal conductivity, compressive strength, density, moisture content and fire‑rating. Copies of ISO 9001 and any applicable EN 13162 or ASTM C578 test certificates should be confirmed before order finalisation. It is advisable to obtain a physical sample - often a 600 mm × 600 mm × 20 mm panel - to verify dimensional tolerances and material performance in‑house. Verify that the HS code on the commercial invoice matches the product description and that packaging meets the buyer’s moisture‑protection requirements. Typical minimum orders are one 20‑ft container (≈10‑12 m³) with lead times of 30‑45 days, so early confirmation of specifications helps avoid delays.
Frequently Asked Questions About Laizhou Mingfa Thermal Insulation Material Co., Ltd
What types of calcium silicate insulation products does the company offer?
The catalogue lists ten products, including panels for new‑energy battery protection, 1000 °C steel furnace panels, graphite‑enhanced boards, fire‑proof waterproof sheets, non‑asbestos construction boards, kiln insulation, furnace back insulation, and ladle‑lining boards. All items are calcium silicate board materials and fall under HS codes 6806‑6815.
Which HS codes are used for the calcium silicate boards?
The products are assigned HS codes 6808.00, 6810.99, 6806.90, 6810.19, 6903.90 and 6815.99, covering general calcium silicate boards, refractory plates and related ceramic items.
What standard specifications should buyers verify for these boards?
Buyers typically check thermal conductivity (0.09‑0.12 W/m·K), compressive strength (5‑15 MPa), bulk density (0.30‑0.50 g/cm³), moisture content (<0.5 %) and fire‑rating (EN 13501‑1 A1). Test reports should reference these parameters.
Are any certifications required for importing calcium silicate insulation from China?
While the supplier’s specific certificates are not listed, importers usually request ISO 9001 quality‑management certification and compliance with EN 13162 or ASTM C578 for calcium silicate boards. Buyers should ask the supplier to provide copies of these documents.
What packaging and shipping formats are typical for these products?
Boards are normally palletised, wrapped in moisture‑proof film and loaded into 20‑ft or 40‑ft containers. Common export terms include FOB Chinese ports or CIF to the destination, with each container holding roughly 10‑12 m³ of product.
How can a buyer obtain a sample before placing a full order?
Buyers can request a sample panel - commonly 600 mm × 600 mm × 20 mm - accompanied by a material data sheet and test report. Samples are shipped under a small‑parcel term such as DAP or DPU, and the supplier usually confirms availability within a few business days.
What is the typical lead time and minimum order quantity?
For most calcium silicate board lines, lead time ranges from 30 to 45 days after order confirmation, and the minimum order is often set at one 20‑ft container, roughly 10 cubic metres of product.
Which industries most commonly import these calcium silicate boards?
Major importers are the metallurgy, glass‑making, cement‑kiln, petrochemical and non‑ferrous metal sectors, which use the boards for furnace linings, kilns and high‑temperature thermal protection.
