Rutile titanium manufacturers

When purchasing Rutile TiO2, you must prioritize TiO2 content (typically ≥93%), *brightness (L)**, and tinting strength. For coatings and plastics, the surface treatment (Alumina, Silica, or Zirconium) is critical as it determines weather resistance and dispersibility. Ensure the particle size distribution is narrow (average 0.2-0.3 microns) to guarantee optimal opacity and gloss in the final application.

You should request the oil absorption value (usually 16-22g/100g); a lower value generally indicates better flow in plastics. For outdoor paints, verify the durability grade—Rutile produced via the chloride process often offers superior UV resistance and color stability compared to the sulfate process. Always ask for a Technical Data Sheet (TDS) tailored to your specific industry use case.

Suppliers must provide ISO 591-1:2000 classification (typically R2 or R3 grade). For exports to Europe, REACH registration is mandatory. If the TiO2 is intended for food-contact packaging or cosmetics, ensure it meets FDA (US Food and Drug Administration) or EU 10/2011 regulations. A valid Material Safety Data Sheet (MSDS) is essential for international shipping and customs clearance.

Request a Certificate of Analysis (COA) for every batch. For large-scale B2B orders, it is highly recommended to engage a third-party inspection agency (like SGS or Intertek) to perform pre-shipment sampling and testing. This ensures the whiteness, purity, and moisture content align with the pre-approved gold sample.

The biggest risks are product adulteration (mixing with cheaper Anatase or fillers) and price volatility. Mitigate this by sourcing from verified manufacturers on Made-in-China.com who have passed on-site audits. Use Trade Assurance or Letters of Credit (L/C) to secure payments, ensuring funds are only released upon verification of shipping documents and quality compliance.

Rutile TiO2 is moisture-sensitive. Ensure the supplier uses multi-layer moisture-proof paper bags or 1000kg jumbo bags with inner plastic liners. For sea freight, specify palletized loading with shrink-wrap to prevent bag breakage and contamination. Ensure the container is dry and clean to avoid external odors or chemical cross-contamination during transit.

Chemical prices fluctuate with raw material (ilmenite ore) costs and environmental regulations. Negotiate based on volume-based pricing tiers; orders exceeding 20 tons (one 20GP container) usually trigger significant discounts. Confirm the production lead time (typically 7-15 days) and ensure the supplier provides a fixed-price window to protect against sudden market spikes during the contract period.

While Rutile TiO2 is generally classified as non-hazardous cargo, you must provide the Non-DG (Dangerous Goods) Certificate for air or sea freight to avoid delays. Ensure the HS Code (3206111000) is correctly declared to benefit from applicable trade agreements or tax rebates. Always clarify Incoterms (FOB vs. CIF) to define who bears the risk and cost of international insurance.
