Titanium dioxide

Selecting the correct grade depends primarily on the crystal structure: Rutile or Anatase. Rutile TiO2 is preferred for outdoor coatings and plastics due to its superior weather resistance and high refractive index, which provides better UV protection. Anatase TiO2 is commonly used in paper, ceramics, and rubber because it is softer and less abrasive. For high-end applications, ensure the product has undergone inorganic and organic surface treatments (like Alumina or Silica coating) to improve dispersibility and gloss retention.

Buyers must evaluate the TiO2 content (typically ≥93% for Rutile), *brightness (L)**, and tinting strength. Crucial performance metrics include oil absorption value, which affects the viscosity of the final formulation, and particle size distribution; a narrow distribution ensures optimal opacity and hiding power. Always request a Certificate of Analysis (COA) to verify these parameters against your production requirements.

For international trade, compliance with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) is essential for the EU market. If the TiO2 is intended for food contact packaging or cosmetics, it must meet FDA (Food and Drug Administration) or E171 standards (though note regional bans in food). Ensure the manufacturer holds ISO 9001 for quality management and ISO 14001 for environmental management, as TiO2 production is chemically intensive.

The Chloride process generally produces TiO2 with a brighter, more neutral white tone and a narrower particle size distribution, making it ideal for high-performance coatings. The Sulfate process is more versatile, capable of producing both Anatase and Rutile grades, and is often more cost-effective for general-purpose applications. Buyers should choose based on whether their priority is extreme color consistency (Chloride) or economic feasibility (Sulfate).

The primary risks include quality inconsistency between batches and moisture damage during sea transit. To mitigate this, use Made-in-China.com's inspection services to verify the cargo before loading. Ensure the packaging consists of multi-layer moisture-proof bags (25kg paper-plastic bags or 1-ton jumbo bags) and that the container is inspected for leaks to prevent clumping or degradation of the powder.

Negotiation should focus on volume-based pricing tiers and payment security. For large orders, request a 15-20% discount compared to sample prices. Utilize Trade Assurance through Made-in-China.com to ensure funds are only released upon proof of shipment. Additionally, negotiate for fixed pricing contracts (3-6 months) to protect your business from the volatility of raw material costs (ilmenite ore).

While Titanium Dioxide is generally classified as non-hazardous for transport, you must provide a Material Safety Data Sheet (MSDS) and a Certification for Safe Transport of Chemical Goods. Ensure the supplier uses palletized shipping with shrink-wrap to prevent bag breakage. For shipping to specific regions, confirm the HS Code (typically 320611) to accurately calculate anti-dumping duties, which can significantly impact the total landed cost in markets like the EU or India.

Prioritize Audited Suppliers who have undergone on-site verification by third-party agencies like SGS or Intertek. Check their export history and production capacity to ensure they can handle bulk orders. A reliable supplier should be able to provide factory photos, production line videos, and a list of previous international clients to demonstrate their experience in the global chemical trade.
