Shower glass

Safety is the paramount concern for shower glass. You must ensure the glass is tempered (toughened) and meets regional safety glazing standards. For the US market, look for SGCC (Safety Glazing Certification Council) certification and compliance with ANSI Z97.1. For the European market, CE marking and EN 12150-1 compliance are mandatory. These certifications guarantee that the glass, if broken, will shatter into small, blunt granular chunks rather than sharp shards, significantly reducing injury risks.

The choice depends on the enclosure design. For frameless shower doors, a thickness of 10mm (3/8") or 12mm (1/2") is required to provide structural stability and a premium feel. For framed or semi-frameless units, 6mm (1/4") or 8mm (5/16") is usually sufficient. Additionally, consider Low-Iron Glass (Ultra-Clear) to avoid the green tint found in standard clear glass, especially if the bathroom has white tiles, and prioritize Easy-Clean (Hydrophobic) coatings which reduce water spots and maintenance by up to 90%.

Precision is critical because tempered glass cannot be cut or drilled after the toughening process. You must provide the supplier with exact CAD drawings specifying hole locations for hinges and handles. Ensure all edges are polished (Flat Polish or C-shape) to prevent handling injuries. Furthermore, verify that the hardware (hinges, rollers, and brackets) is made of Stainless Steel 304 or Solid Brass to prevent corrosion in high-humidity environments.

Request the supplier to perform a Fragmentation Test, where a sample is broken to count the number of particles in a 50x50mm area (standard is usually >40 particles). To check for clarity and purity, ask about the Nickel Sulfide (NiS) inclusion rate; high-quality manufacturers use Heat Soak Testing (HST) to eliminate glass panes prone to spontaneous breakage, ensuring long-term reliability for the end-user.

The biggest risk is breakage during transit and unloading. You must mandate Professional Export Plywood Crating with shock-absorbing materials (like EPE foam) between each sheet. Avoid solid wood crates unless they are ISPM-15 fumigated. For large orders, specify End-cap Crates which allow for easier unloading via forklift. It is highly recommended to purchase All-Risk Marine Insurance to cover potential losses during sea freight.

Utilize the Secured Trading Service on Made-in-China.com to protect your payment until delivery is confirmed. When negotiating, request a Pre-shipment Inspection (PSI) by a third party (like SGS or Intertek) to verify the quantity, dimensions, and hole placements. For bulk orders, negotiate a progressive payment structure (e.g., 30% deposit, 70% against the Bill of Lading) to maintain leverage over quality control.

Before importing, check the HS Code (typically 7007.19) for glass products in your country. Be aware that some regions (like the EU or USA) may have anti-dumping duties or countervailing duties (CVD) on specific types of Chinese glass. Consult with a local customs broker to calculate the Total Landed Cost, including any protective tariffs, to ensure the economic feasibility of the import.

Always record a video of the container seal breaking and the entire unloading process. If damage is found, take high-resolution photos of the broken glass and the condition of the crates. Report the issue to the supplier and the insurance company within 7 days of arrival. A reputable supplier should offer a replacement policy or credit for glass that arrives broken or fails to meet the specified dimensional tolerances (usually ±2mm).
