Pigments · CAS 13463-67-7 · From China
You order a grade name — R-996, R-902, A-100 — but a grade name is only a target spec. What decides what actually lands in your factory is the one thing you can't read off the bag: the process route. True chloride-process rutile, or sulphate anatase dressed up to hit a premium number? We fix the crystal form and process route to your application, prove whiteness and hiding power on a retained sample, then load the container.

Why Titanium Dioxide Buying Is Different
Most buyers open with a grade name — "give me R-996," or "R-902 will do," or "the cheap A-100." It's useful shorthand, but a grade name is just a published target spec. What actually determines the pigment in the bag is two things you can't see on the label: the crystal form — rutile or anatase — and the process route — chloride or sulphate. A sulphate-process anatase can be dressed to nearly match a premium datasheet's TiO2% and whiteness on paper, then chalk and yellow within a season once it's on an exterior wall, because anatase is simply the wrong crystal for UV. No "R-996 equivalent" line on a quotation protects you from that — the certificate can be true and the pigment still wrong for your job.
So this page is built around the one distinction that decides everything: the process-route and crystal-form matrix below, which sends you to the right family of titanium dioxide, and the retained-sample checks that prove the whiteness and hiding power on your own product before any container is booked.
Rutile · Anatase · Chloride · Sulphate
Three families cover almost every job. Read across: hiding power, outdoor durability, whiteness, relative cost, the applications each family is built for, and the equivalent-to grade channel that name is known by. Match your end use to a family first — the grade number is second.
| Family (crystal · process) | Hiding power & tint | Outdoor durability | Whiteness & undertone | Relative cost | Best-fit applications | Equivalent-to channel |
|---|---|---|---|---|---|---|
| Rutile · Chloride the premium route |
Highest top opacity & tint strength |
Excellent — holds colour & gloss outdoors for years | Neutral, clean blue-white undertone | Highest | Exterior architectural & masonry paint, automotive & industrial coatings, top-tier plastic masterbatch | Equivalent-to R-996-class chloride rutile channel |
| Rutile · Sulphate the workhorse route |
High strong, slightly below chloride |
Good with the right coating — mid-tier exterior, all interior | Bright white, marginally warmer undertone | Mid | Interior & general architectural paint, emulsion paint, mid-tier plastics, printing ink, sealants | Equivalent-to R-902-class sulphate rutile channel |
| Anatase · Sulphate indoor / economy route |
Moderate lower tint strength |
Indoor only chalks & yellows under UV | Soft bluish brightness | Lowest | Interior flat paint, paper, rubber, ceramics & enamels, welding electrodes, indoor plastics | Anatase A-100-class channel |
"Equivalent-to" means matched to the published spec class a grade name is known for — crystal form, process route, TiO2% and surface treatment — not the branded product itself. The golden rule: never put anatase where the sun hits it.
Tell us the end use — we'll name the familySee The Actual Product
The Material
Bright rutile or anatase TiO₂ — the process route behind the grade, verified.
How It Ships
Palletised 25 kg laminated bags from live stock.
In Use
Opacity and whiteness for coatings, plastics and paper.
Lock The White, Lot After Lot
"Looks white" is not a spec. Two lots of genuine TiO2 can still differ enough to ruin a colour match in your paint or masterbatch. We pin the white to a physical reference and a measured number, then hold every future lot to it.
Sign a reference sample
The approved lot from your first shipment becomes the retained master. Both sides keep a sealed, dated portion.
Match under one light
Every new lot is compared to the master under a single controlled light source (D65), not window light or "it looks fine."
Measure the ΔE
A colorimeter puts a number on the colour difference. The ΔE is recorded on the COA and held under the ceiling you set.
Third-party ISO 591 + hiding power
Before shipment, an independent lab classifies the TiO2 to ISO 591 and measures hiding power & tint strength.
Load only when it matches
Any lot outside your ΔE ceiling or the wrong ISO 591 type is rejected before it leaves the plant — not discovered at your port.
Dry From Plant To Port
TiO2 is hygroscopic. Absorbed moisture cakes the powder, and a caked bag disperses unevenly in your mill or extruder — dropping your hiding power even when the titanium dioxide inside is completely genuine. Three layers keep it dry across a long ocean leg to a humid destination.
25 kg laminated woven PP or paper-plastic composite bags with an inner PE liner, heat-sealed rather than left stitch-open.
The failure it stops
Single-wall stitched bags breathe humid air straight into the powder.
Palletised, corner-boarded and stretch-wrapped so bags don't slump, abrade or split against each other in transit.
The failure it stops
Loose floor-loaded bags chafe, tear and spill white powder across the container floor.
Desiccant bags plus a container liner for long, humid routes; cargo loaded away from the doors where condensation collects.
The failure it stops
"Container rain" dripping onto pallets after weeks at sea, caking the top bags solid.
Packing spec is agreed in writing before production, and a third-party pre-shipment inspection can confirm bag counts, seals and loading before the balance payment.
Get moisture-proof, inspected TiO2Reading The Quotes
Two quotes for "TiO2, 25 kg bags, R-996" can sit far apart and both be honest — because "R-996" is a target, not a single product. The process route sets the floor: chloride-process rutile carries a higher, steadier cost base than sulphate, and rutile of any route sits above anatase. When a quote lands well under the market for chloride rutile, the usual explanation isn't a better factory — it's sulphate rutile, an anatase blend, or filler quietly extended into the bag.
We quote against your locked crystal form and process route, name the factory, and put measured TiO2%, whiteness and ΔE on the COA — so you're comparing the same pigment, not the same grade number.

Process route
Chloride vs sulphate. Chloride-process rutile is the more expensive, more consistent product; sulphate is cheaper — and a different pigment, not a discount on the same one.
Crystal form & TiO2 content
Rutile sits above anatase, and a high assay (≥93–94% TiO2) sits above extended grades. Pay for the assay you actually need, and no less.
Surface treatment
The Al2O3 / SiO2 and organic coating that tunes durability, dispersion and weatherability costs money. A "universal" treated grade sits above an untreated one.
Filler extension
The cheapest "TiO2" is cut with calcium carbonate or blanc fixe to lower the assay — a bargain per ton that costs more per unit of hiding power.
What We Ship
Every lot ships with a certificate of analysis carrying the measured values — TiO2 content, whiteness and the ΔE against your retained reference — plus the production date on the bags. Independent third-party inspection, including ISO 591 classification and a hiding-power test, is available before the balance payment on any order.
You don't have to fill a container with one pigment. A trial order of titanium dioxide from 1 ton rides alongside iron oxide pigments and other colourants in the same box — one container, one set of documents, one bill of lading to your port, whether that's in Central Asia, South America, Europe, the Middle East, Africa or Southeast Asia.

Straight Answers
Anything exposed to sunlight or weather — exterior paint, road-marking, durable masterbatch — needs rutile, and chloride-process rutile is the most durable. Indoor flat paint, paper, rubber, ceramics and welding electrodes can use anatase, which is cheaper and perfectly fine there. The one rule you can't break: never put anatase outdoors, because it chalks and yellows under UV. Tell us the end use and we point you to the right crystal form before we talk grades.
Yes. Chloride-process rutile has the highest tint strength, the cleanest blue-white undertone and the best outdoor durability — it's the premium coatings choice. Sulphate-process rutile is a strong mid-tier for interior and general use, and the sulphate route is also how anatase is made. The problem is that the same "R-996" written on a bag can hide either route, so we fix the process route in the contract spec, not just the grade number.
We pin the white to a retained reference sample, match every lot against it under a single controlled light source, and put a measured ΔE on the COA held under a ceiling you set. On top of that, an independent third-party lab can classify the titanium dioxide to ISO 591 and measure hiding power and tint strength before your balance payment — so the numbers are confirmed while the goods are still in China, not after they land.
We supply to the equivalent-to spec class those grade names are known for — for example an equivalent-to R-996-class chloride rutile channel — matched on crystal form, process route, TiO2 content and surface treatment. We do not relabel or pass off a branded manufacturer's product; you get a pigment built to that published specification and proven on your own sample. If you send the datasheet or grade name, we tell you honestly which family it belongs to and quote the matching material.
Trial orders start from 1 ton. Titanium dioxide consolidates with iron oxide pigments and other chemicals in one container, under one set of documents, so a first order can be a mixed pallet-load that lets you validate the grade and the supply chain before committing to volume. Common grades are usually produced within 7–15 days of order confirmation; ocean transit depends on your route and is confirmed with the quote.
