Titanium dioxide
二氧化钛 / 钛白粉
Titanium dioxide is the most-traded white pigment globally and the single largest pigment line for paint, plastic, paper, and ink applications. Chinese capacity is dominated by Lomon Billions, Henan Billions, and Cnano, with sulphate-process plants in Sichuan and Anhui and chloride-process capacity expanding in Yunnan. The chloride-process grade commands a premium over sulphate for high-durability paint and engineering plastic applications. The 2021 IARC Group 2B classification on inhalable TiO2 has driven labelling changes globally, with REACH harmonised classification under CLP, OSHA HCS in the US, and AICIS notification in Australia. US imports do not carry Section 301 at the bulk-pigment level. This cluster aggregates CAS 13463-67-7 across the regulatory matrix, the substance-level CAS page, and the titanium-dioxide hub with grade selection, packaging economics, and the failure modes that catch first-time buyers.
Glossary
Terms you will meet on this lane
-
REACH, Registration, Evaluation, Authorisation and Restriction of Chemicals
EU chemical regulation requiring importers and manufacturers to register every substance manufactured or imported into the EU above 1 tonne per year. Registration is identity-based and dossier-based, not inventory-lookup-based, which makes it stricter than TSCA in the US.
-
TSCA, Toxic Substances Control Act
US federal law that gives the EPA authority to track and restrict the manufacture, import, processing, distribution, and disposal of industrial chemicals.
-
AICIS, Australian Industrial Chemicals Introduction Scheme
Australian regulatory scheme for industrial chemicals. Replaced NICNAS in July 2020. Categorises chemical introductions by risk and assigns annual reporting obligations to importers and manufacturers.
-
K-REACH, K-REACH
South Korean Act on the Registration and Evaluation of Chemicals, the Korean equivalent of EU REACH. Requires registration of substances manufactured in or imported into Korea above 1 tonne per year. Administered by the Ministry of Environment through NIER. Includes phase-in registration tiers, joint submission requirements, and a designated 'Only Representative' mechanism for non-Korean manufacturers.
-
IECSC, Inventory of Existing Chemical Substances in China
The Chinese national chemical inventory listing substances legally manufactured, imported, used, or sold in China before 2003. A substance not on IECSC requires a New Chemical Substance Notification (NCSN) under MEE Order 12 before it can be manufactured or imported into China. Functionally similar to TSCA in the US and REACH in the EU but with distinct procedural requirements.
-
SDS, Safety Data Sheet
The 16-section document that communicates the hazards, handling, storage, and emergency response information for a chemical product. Required at destination customs for any classified hazardous chemical and at the buyer's site for worker safety. SDS is the GHS-aligned successor to the older MSDS format.
-
COA, Certificate of Analysis
A document issued by the manufacturer (or by an accredited third-party lab) certifying that a specific batch of a chemical or material meets the agreed specification. Lists tested parameters, results, the test methods used, and a batch number that ties back to production.
-
HS Code, Harmonized System Code
A six-digit international product classification code used by customs authorities worldwide to identify goods, assess duties, and apply trade controls. Countries extend the six-digit base with additional digits for tariff and statistical purposes (10-digit HTS in the US, 8-digit CN code in the EU, 10-digit AHECC in Australia).
-
FOB, Free On Board
Incoterm under which the seller delivers the goods on board the vessel at the named port of shipment. Risk and cost transfer to the buyer once the cargo crosses the ship's rail. The buyer arranges and pays for sea freight, marine insurance, and all destination-side costs.
-
CIF, Cost, Insurance, and Freight
Incoterm under which the seller is responsible for the cost of the goods, marine insurance, and sea freight to the named destination port. Risk transfers from seller to buyer when the goods are loaded on board at the origin port, but cost responsibility extends to destination port arrival.

Sourzi operator note
Chloride-versus-sulphate process is the loadbearing distinction at the spec stage. Once the cargo is in the drum, the lab cannot tell the buyer which process line produced it.
