About Shandong Wensheng Glass Co., Ltd. - Insulated & Laminated Glass Supplier in China

Shandong Wensheng Glass Co., Ltd. is based in Shandong province, China and currently lists five distinct glass products in its catalogue. The supplier’s active product count of 5 covers two primary categories - insulated glass and laminated glass - which fall under HS Chapter 70 (flat glass, HS code 7002). The catalogue includes clear laminated glass in thicknesses of 6.38 mm, 8.38 mm and a generic clear laminated entry, as well as a 12 mm clear toughened glass and a separate insulated glass unit. Each product is described by its nominal thickness and treatment, reflecting standard safety‑glass specifications used in construction and automotive glazing. The supplier’s classification as an imported, harbor‑tier provider indicates that it is positioned for overseas buyers seeking Chinese‑origin glass solutions.

The product list shows a focus on clear, high‑transparency glass types that are commonly required for façade systems, curtain walls, and interior partitions. The 12 mm toughened glass meets typical safety standards such as EN 12150 for tempered glass, while the laminated items correspond to EN 12600 impact testing for safety glazing. Insulated glass units are generally assembled with two glass panes separated by a spacer and sealed with desiccant, targeting thermal performance metrics like U‑values below 1.2 W/m²·K. No additional certifications are stated in the supplied data, so buyers should verify compliance with relevant European or North American standards before purchase.

Product Range and Specialties of Shandong Wensheng Glass Co., Ltd.

The catalogue offers clear laminated glass in two specific thicknesses - 6.38 mm and 8.38 mm - plus a generic clear laminated entry, a 12 mm clear toughened sheet, and an insulated glass unit. In the glass industry, laminated glass is typically produced with a polyvinyl butyral (PVB) interlayer of 0.38 mm to 0.76 mm, delivering acoustic damping and post‑breakage safety. Toughened glass of 12 mm thickness is standard for high‑impact applications and is usually tested to a minimum surface compression of 720 MPa according to ASTM C1048. Insulated glass units (IGUs) are assembled with two panes ranging from 4 mm to 6 mm each, separated by a spacer bar, and sealed to achieve overall panel thicknesses between 20 mm and 30 mm. Buyers commonly request performance data such as U‑value, solar heat gain coefficient (SHGC), and visible light transmittance (VLT) for IGUs.

Industry practice for clear glass includes low‑iron (IC 71) grades that achieve a light transmission of 90 % or higher, while safety‑glass standards often require compliance with EN 12600 impact resistance or ASTM C1172 for laminated glass. Typical HS sub‑heading for such flat glass products is 7002.31 (flat glass, laminated) and 7002.30 (tempered). The supplier’s product set aligns with these classifications, allowing buyers to map the items to standard customs codes and quality expectations.

Trade and Export Information - Shandong Wensheng Glass Co., Ltd.

Chinese glass manufacturers export primarily to the EU, United States, Middle East, and Southeast Asian construction markets, where demand for energy‑efficient façade glazing is strong. The HS Chapter 70 code family (7002) is routinely inspected by customs for compliance with safety markings, CE conformity for EU markets, and ASTM references for North America. Commonly required certifications include CE marking under the Construction Products Regulation (CPR), ISO 9001 quality management, and product‑specific test reports such as EN 12600 for laminated safety glass or EN 12150 for tempered glass. Export logistics typically involve palletizing sheets on wooden frames, loading them in 20‑ft or 40‑ft containers with protective edge boards, and using Incoterms like FOB or CIF to the destination port.

Shandong’s glass sector benefits from established port facilities in Qingdao and Lianyungang, enabling efficient containerized shipments. Buyers should confirm that the supplier can provide the required phytosanitary or customs documentation for glass, although such goods are generally exempt from quarantine inspections. Requesting a pre‑shipment inspection report (PSIR) from a recognized third‑party agency can mitigate risk in high‑value glass orders.

Sourcing from Shandong Wensheng Glass Co., Ltd. - Buyer Guidance

When sourcing laminated or toughened glass from this supplier, request detailed product data sheets that list glass thickness, interlayer type (for laminated), tempering specifications, and performance metrics such as impact resistance, U‑value, and acoustic rating. Ask for third‑party test certificates that reference EN 12600 (laminated) or EN 12150 (tempered) and any CE conformity assessment reports relevant to the target market. Verify the HS code declared for each shipment matches the product description (e.g., 7002.31 for laminated glass) to avoid customs delays.

Confirm packaging details - sheets are usually wrapped in protective film, placed on edge‑protected pallets, and loaded in climate‑controlled containers to prevent breakage. Minimum order quantities for custom thicknesses can range from one pallet (approximately 8 m²) to larger bulk orders; lead times for specialized IGU assemblies are typically 4‑6 weeks after final artwork approval. Ensure that the supplier can supply a sample panel for dimensional and optical verification before committing to full production.

What thickness options are listed for laminated glass?

The catalogue lists clear laminated glass with nominal thicknesses of 6.38 mm and 8.38 mm, plus a generic clear laminated entry without a specific thickness disclosed.

Which safety standards apply to the 12 mm toughened glass?

The 12 mm clear toughened glass is expected to meet EN 12150 (tempered glass) or ASTM C1048, which define minimum surface compression and impact resistance for safety glazing.

What HS codes are typically used for these glass products?

Flat glass items fall under HS Chapter 70, with laminated glass usually classified under 7002.31 and tempered glass under 7002.30; insulated glass units are also covered by 7002.31 when the panes are laminated.

What certifications should a buyer request from a Chinese glass exporter?

Buyers should request CE conformity certificates for EU markets, ISO 9001 quality management certification, and specific test reports such as EN 12600 for laminated glass or EN 12150 for tempered glass.

How is insulated glass typically packaged for export?

Insulated glass units are commonly palletized with edge protection, wrapped in anti‑scrap film, and loaded into 20‑ft or 40‑ft containers with moisture‑absorbing desiccant packs to preserve seal integrity.

What typical lead time is expected for custom laminated glass?

Custom laminated glass orders generally require 4‑6 weeks from final artwork approval, depending on interlayer material availability and production scheduling.

Are there specific import requirements for glass in the EU?

EU importers must ensure CE marking under the Construction Products Regulation, provide a Declaration of Performance, and present test reports confirming compliance with EN 12600 or EN 12150, as applicable.

What documentation is needed for customs clearance of glass shipments?

Customs clearance typically requires a commercial invoice, packing list, the correct HS code declaration, and any applicable safety or CE certificates; a pre‑shipment inspection report can further streamline clearance.
