Titanium dioxide industrial grade

Buyers must distinguish between Anatase and Rutile types. Rutile TiO2 is preferred for outdoor applications due to its superior UV resistance and weatherability, while Anatase is often used in paper and indoor coatings for its bluer undertone. Key metrics include TiO2 content (typically ≥93% for Rutile), oil absorption value (which affects paint viscosity), and particle size distribution to ensure optimal opacity and tinting strength.

Suppliers should provide ISO 591-1:2000 classification reports. For exports to the EU, REACH registration is mandatory. If the TiO2 is intended for food-contact packaging or toys, it must comply with FDA 21 CFR or EN71-3 standards. Always request a current Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch to verify the absence of heavy metal contaminants.

Industrial TiO2 undergoes inorganic and organic surface treatments (e.g., Alumina, Silica, or Zirconia coating). Silica-coated grades offer higher durability for exterior paints, while Alumina-treated grades improve dispersibility in plastics and inks. Understanding the specific coating is crucial for ensuring chemical compatibility with your base resins or solvents.

Prices are heavily influenced by the cost of ilmenite ore and sulfuric acid/chlorine process energy consumption. To optimize costs, consider bulk purchasing (20ft FCL) to reduce per-ton logistics expenses. Buyers should monitor environmental regulation shifts in China, as production halts in major hubs like Sichuan or Shandong can lead to sudden supply shortages and price spikes.

TiO2 is sensitive to moisture and compression. Ensure the supplier uses multi-layer moisture-proof paper bags or ton bags with PE liners. During sea freight, ensure the container is dry to prevent caking, which renders the powder unusable in automated feeding systems. Always verify the palletization and shrink-wrapping quality to prevent bag breakage during transit.

Utilize Made-in-China.com's Secured Trading services to protect your payments. Before full payment, hire a third-party inspector (like SGS or Intertek) to conduct pre-shipment sampling directly from the warehouse. This prevents the 'bait and switch' risk where the sample quality exceeds the bulk delivery quality.

Negotiate based on annual volume commitments rather than spot orders to secure priority allocation during peak seasons. Request a price adjustment formula linked to raw material indexes if you are signing a long-term contract. For new partnerships, start with a trial order of 1-5 tons to test the material's integration into your production line before scaling to full containers.

Confirm the HS Code (typically 320611) to determine import duties in your country. Since TiO2 is a heavy, dense powder, freight weight limits are reached before volume limits; ensure your logistics provider is experienced in handling heavy-load containers. Always clarify Incoterms—while FOB gives you control over freight, CIF may be more convenient if the supplier has high-volume contracts with shipping lines.
