Crushed glass

Selecting crushed glass depends heavily on the intended use. For construction and landscaping, prioritize tumbled or recycled glass with smooth edges to ensure safety. For sandblasting and surface preparation, focus on angularity and hardness (Mohs scale 6-7) to ensure efficient coating removal. If purchasing for terrazzo flooring or resin crafts, verify color consistency and UV resistance to prevent fading over time. Always specify the mesh size (e.g., 1-3mm, 3-6mm) to ensure the grit meets your technical requirements.

B2B buyers should ensure the product is free from organic contaminants, hazardous heavy metals (like Lead or Cadmium), and sharp debris. Request a Material Safety Data Sheet (MSDS) to confirm chemical stability. For filtration purposes, ensure the glass meets ANSI/NSF Standard 61 for drinking water system components. If the glass is intended for export to the EU, verify REACH compliance to ensure no restricted chemical substances are present.

To optimize costs, calculate the Total Cost of Ownership (TCO), including the unit price, heavy-load shipping surcharges, and customs duties. Crushed glass is a high-weight, low-value commodity, so bulk discounts (typically 20-40% for 20ft containers) are essential. Consider sourcing from suppliers on Made-in-China.com who offer flexible packaging options, such as 25kg bags versus 1.5-ton jumbo bags, to reduce local handling and labor costs.

For water filtration, the Effective Size (D10) and Uniformity Coefficient are critical to prevent clogging. For abrasive blasting, the moisture content must be <0.5% to prevent clumping in the blast pot. Ensure the supplier provides a Sieve Analysis Report to guarantee that the particle size distribution aligns with your machinery's specifications.

The biggest risks include moisture contamination during sea transit and discrepancies in particle size. To mitigate this, insist on moisture-proof lining in jumbo bags and request a Pre-Shipment Inspection (PSI). Using Made-in-China.com's Secured Trading services can help protect your payment until the quality is verified by a third-party inspector.

Since crushed glass is extremely heavy, freight costs can often exceed the product value. Negotiate FOB (Free On Board) terms to maintain control over your shipping line and avoid hidden 'arrival fees' common in CIF terms. Ensure the supplier is experienced in weight-optimized container loading to maximize the 20ft container weight limit (usually 21-27 tons depending on the route).

Always verify if the supplier is an Audited Supplier on Made-in-China.com, which confirms their manufacturing capabilities and business legitimacy. For first-time orders, use Letter of Credit (L/C) or Escrow-based payments to ensure the supplier only receives funds after providing the Bill of Lading and Quality Certificate.

Check for anti-dumping duties on glass products in your specific country, as some regions impose high tariffs on processed glass from overseas. Ensure the supplier provides a Certificate of Origin to help you benefit from any applicable Free Trade Agreements (FTAs), which can significantly reduce or eliminate import tariffs.
