White titanium dioxide rutile manufacturers

When sourcing Rutile TiO2, you must prioritize TiO2 content (typically ≥93%), *brightness (L)**, and tinting strength. For high-end applications, evaluate the surface treatment (Alumina, Silica, or Zirconium), as this determines the pigment's weather resistance and dispersibility in different mediums like plastics or coatings.

Different grades serve different purposes. Universal grades are versatile, but for outdoor coatings, you need high weatherability (silica-coated). For plastics and masterbatches, look for grades with low oil absorption and high melt flow compatibility to prevent processing issues.

Ensure the supplier provides a Certificate of Analysis (COA) for every batch. For exports to the EU, REACH registration is mandatory. If the TiO2 is used in food packaging or toys, it must comply with FDA (21 CFR) or EN71-3 standards. Always verify the ISO 591-1:2000 classification (usually R2 or R3 for Rutile).

Request a pre-shipment sample from the actual production lot. Use X-ray Fluorescence (XRF) to check purity and Particle Size Distribution (PSD) analysis; a narrow PSD ensures better opacity and gloss. Professional buyers often use third-party inspectors like SGS or Intertek to verify these metrics at the loading port.

The biggest risks include adulteration (mixing with Calcium Carbonate or Lithopone) and weight discrepancies. To mitigate this, only source from Verified Suppliers on Made-in-China.com and insist on Trade Assurance or Letter of Credit (L/C) payment terms to protect your capital.

TiO2 prices fluctuate based on ilmenite ore costs and environmental regulations. Negotiate based on volume-based tiered pricing and try to lock in a quarterly fixed price if you have stable demand. Always ask for FOB or CIF quotes to compare total landed costs effectively.

Standard packaging is 25kg multi-layer paper bags or 500kg/1000kg jumbo bags. Ensure the pallets are ISPM 15 heat-treated for international customs. Since TiO2 is a fine powder, moisture protection is critical; verify that the container uses desiccants and high-quality liners to prevent clumping during sea transit.

Be aware of Anti-Dumping Duties (ADD) that certain regions (like the EU or India) may impose on TiO2 originating from specific countries. Check your local Harmonized System (HS) Code (typically 3206.11) regulations to calculate accurate import tariffs before finalizing the contract.
