About Qinhuangdao Silide Ceramic Technology Co., Ltd - Dental Equipments & Materials Supplier in China

Qinhuangdao Silide Ceramic Technology Co., Ltd operates from Qinhuangdao, China and currently lists five distinct dental zirconia products. All items fall under the HS‑code 9021.21 family for ceramic dental articles, except the HT block which is classified under HS‑code 6909.11 for other ceramic articles. The catalogue includes the KingCH 3D ProMax Dental Zirconia Block (98 × 14 mm), three multilayer or standard zirconia blocks (ST‑ML, ST‑C, ST), and a high‑temperature (HT) zirconia block. Each product is described by its material composition, ranging from yttria‑stabilized zirconia (Y‑TZP) to multilayer zirconia ceramics with Y₂O₃ stabilizer. The supplier’s listed top category is Dental Equipments & Materials, indicating a focus on prosthetic and restorative dental components.

The five products are all zirconia blocks intended for CAD/CAM milling in dental laboratories. Materials are specified as Y‑TZP or multilayer ZrO₂ with yttria stabilizer, which are typical for achieving translucency and high flexural strength in crowns and bridges. Dimensions are provided for the 3D ProMax block, while the other blocks follow standard industry sizes compatible with most milling units. The inclusion of both standard and high‑temperature grades reflects the range of translucency and strength requirements across restorative workflows. These blocks are part of the global supply chain for dental prosthetics that demand precise micro‑structure and biocompatibility.

Product Range and Specialties of Qinhuangdao Silide Ceramic Technology Co., Ltd

The catalogue presents five zirconia block types, each identified by a distinct product name and material formulation. Four blocks (3D ProMax, ST‑ML, ST‑C, ST) are recorded under HS‑code 9021.21 and are composed of yttria‑stabilized zirconia, either as a single‑layer 3Y‑TZP or as multilayer ceramics that combine varying yttria contents to modify translucency. The fifth block (HT) falls under HS‑code 6909.11 and is described as a high‑temperature Y‑TZP ceramic, often used where additional thermal stability is required during sintering.

In the dental zirconia market, common grades include 3Y‑TZP (≈3 % yttria) for high strength, 4Y‑TZP for balanced strength and translucency, and 5Y‑TZP (≈5 % yttria) for maximum translucency. Typical specifications cite flexural strength above 900 MPa, hardness around 1200 HV, and grain sizes below 0.5 µm after sintering. Multilayer blocks are engineered with graded translucency layers to mimic natural tooth anatomy. Buyers usually expect dimensions that fit standard milling trays (e.g., 12 × 12 × 12 mm to 100 × 14 mm) and a sintering temperature range of 1450‑1550 °C. The supplier’s product list aligns with these industry standards, offering both standard and high‑temperature options for diverse clinical requirements.

Trade and Export Information - Qinhuangdao Silide Ceramic Technology Co., Ltd

China is a major exporter of dental zirconia, with the majority of shipments destined for North America, the European Union, and the Middle East. HS‑code 9021.21 covers "Ceramic articles for dental or medical uses," which commonly require conformity to ISO 13485 quality management and CE marking for EU markets. The HT block classified under HS‑code 6909.11 is treated as a general ceramic article, still subject to material safety data sheets and, for medical use, FDA 510(k) clearance when entering the United States. Export logistics typically involve 20‑ft containers holding 1,200‑1,500 blocks, packed in sealed, moisture‑controlled foam boxes to prevent chipping. Incoterms such as FOB Qinhuangdao or CIF Shanghai are frequently used, with buyers arranging customs clearance under the relevant dental device tariff headings.

Sourcing from Qinhuangdao Silide Ceramic Technology Co., Ltd - Buyer Guidance

When sourcing zirconia blocks from this supplier, request the latest material test report confirming yttria content, grain size, flexural strength, and translucency measurements (e.g., spectrophotometer L*a*b* values). Ask for copies of ISO 13485 certification and any CE or FDA documentation that the supplier has obtained for the specific block grades. Verify that the dimensions and tolerances match your CAD/CAM system’s requirements, and consider ordering a pilot sample to assess milling behavior and final shade matching. Typical minimum order quantities for ceramic blocks range from one pallet (approximately 300‑400 blocks) to a full container, with lead times of four to six weeks after sample approval. Ensure packaging specifications include double‑wall cardboard cartons with internal foam inserts and moisture‑absorbing desiccants to maintain material integrity during sea transit.

What material composition is used in the KingCH 3D ProMax Dental Zirconia Block?

The block is made of yttria‑stabilized zirconia (Y‑TZP) with a multilayer structure of ZrO₂ and Y₂O₃, classified under HS‑code 9021.21.

Which HS‑code applies to the KingCH Dental Zirconia Block HT?

The HT block is listed under HS‑code 6909.11, covering other ceramic articles.

What typical mechanical properties should I expect from these zirconia blocks?

Dental zirconia blocks of this type usually exhibit flexural strength above 900 MPa, Vickers hardness around 1200 HV, and grain sizes under 0.5 µm after sintering.

Are any certifications required for importing these zirconia blocks?

Buyers normally request ISO 13485 quality management certification, CE marking for EU imports, and FDA 510(k) clearance for U.S. entry, although such documents must be verified with the supplier.

What is a common minimum order quantity for these blocks?

Typical MOQ is one pallet, roughly 300‑400 blocks, though larger orders are often shipped in 20‑ft containers.

How are the blocks packaged for export?

Blocks are packed in sealed foam‑lined cartons with moisture‑absorbing desiccants, then placed in double‑wall shipping boxes suitable for container loading.

What lead time should I plan for after confirming a sample?

Lead times generally range from four to six weeks from sample approval to shipment, depending on production scheduling and container availability.
