Quick answer: Talc is a soft magnesium silicate, Mg3Si4O10(OH)2, sold in grades defined by particle size, whiteness, purity and testing. Industrial grades for plastics, paint, paper and ceramics are the volume market. Cosmetic, pharmaceutical and food grades carry tighter limits on heavy metals, microbes and asbestos. The average US milled talc price was about US$330 per tonne in 2025. Fine, high-white and certified grades sell well above that figure.
What is talc powder?
Talc is a hydrated magnesium silicate and the softest mineral on the Mohs scale, at 1. Pure talc contains 31.7% MgO, 63.5% SiO2 and 4.8% water by weight. The crystals form thin plates, which give talc its slip, its barrier effect in plastics and coatings, and its oil-absorbing feel in cosmetics. Talc is chemically inert, water-repellent and stable at high temperatures.
No talc deposit is pure. Ores carry chlorite, dolomite, magnesite or other minerals in different amounts. These associated minerals change whiteness, hardness, chemistry and price, so the deposit and the mill decide the grade as much as the grinding does.
Talc powder grades by application
Every talc grade is built for a use. The table shows where each grade goes and what the buyer controls. Typical figures are common buyer targets, not universal standards. Your own trials and regulations set the final limits.
| Grade | Main uses | Typical particle size | Typical whiteness | Critical controls |
|---|---|---|---|---|
| Cosmetic | Body powder, face powder, eye shadow, pressed powders | Micronized, D50 about 5 to 15 µm, 325 mesh residue near zero | 90% and above | Asbestos testing, heavy metals, microbial limits, odour |
| Pharmaceutical | Tablet glidant, lubricant, excipient | Fine to micronized | High | USP, Ph. Eur. or JP monograph, including asbestos chapter |
| Food (E553b) | Anti-caking, rice polishing, chewing gum dusting | Fine | High | Food additive specification, heavy metals, asbestos-free |
| Plastics | Polypropylene car parts, polyethylene, nucleation, film anti-block | D50 about 1 to 15 µm by use | 80% to 95% by colour need | Top cut, aspect ratio, moisture, surface treatment |
| Paint and coatings | Extender in primers, wood coatings, road paint | D50 about 5 to 20 µm | 85% and above | Oil absorption, fineness of grind, top cut |
| Paper | Filler, coating pigment, pitch and stickies control | Fine | High brightness | Brightness, abrasion, particle shape |
| Ceramics | Wall tiles, sanitaryware, cordierite for catalytic converters | Ground to 200 to 325 mesh | Fired colour matters more than raw whiteness | Chemistry (MgO, CaO, Fe2O3), loss on ignition |
| Rubber | Filler, dusting and anti-tack agent | Ground | Moderate | Moisture, particle size, cost |
| Agriculture and feed | Carrier, anti-caking, seed coating | Ground | Moderate | Heavy metals, feed or crop rules |
A plastics grade with 88% whiteness and no microbial test is a sound industrial product. Sold into a cosmetic formula, the same powder becomes a compliance risk. Name the end use in every enquiry so the supplier quotes the right grade and documents.
Talc mesh to micron conversion chart
Suppliers quote talc in mesh, in microns or as a D50 or D97 value. Mesh counts the openings per linear inch of a sieve. Higher mesh means finer powder. Use this chart to compare offers written in different units.
| Mesh | Opening (microns) | Typical talc use |
|---|---|---|
| 100 | 150 | Coarse filler, rubber dusting |
| 200 | 75 | Ceramics, roofing, general industrial |
| 325 | 45 | Standard ground talc for paint, rubber, plastics |
| 400 | 38 | Finer paint and plastics grades |
| 600 | about 23 | Fine fillers, paper |
| 800 | about 18 | Fine plastics and coatings |
| 1250 | about 10 | Micronized cosmetic and performance plastics grades |
| 2500 | about 5 | Ultrafine grades, film, nucleation |
100 to 400 mesh follow ASTM E11 sieve openings. Above 400 mesh, the micron values follow common trade convention, because standard sieves stop near 20 µm and laser diffraction takes over.
Fine talc is sized by laser diffraction, not sieves. Two suppliers both calling a grade "1250 mesh" can deliver very different D50 and D97 values. Ask for the full particle size distribution, the instrument and the method on the certificate of analysis.
Talc specification sheet: what to ask for
A complete talc specification names each parameter, a limit and a test method. Use the list below to check any supplier data sheet or certificate of analysis.
| Parameter | Why the parameter matters | Typical buyer target |
|---|---|---|
| Talc content | Sets performance per tonne and the level of associated minerals. | Stated by XRD. Higher for cosmetic and plastics grades. |
| D50 and D97 (top cut) | D50 sets fineness. D97 controls specks, film defects and surface finish. | Agreed range with laser method named |
| Sieve residue | Catches coarse particles in ground grades. | 325 mesh residue at 1% or below for fine grades |
| Whiteness or brightness | Drives colour in cosmetics, paper and light plastics. | 85% to 95% by grade, with method (ISO brightness or L*a*b*) |
| Moisture | Affects flow, feeding and compounding. | 0.5% maximum is a common target |
| Loss on ignition | Flags carbonate content, key for ceramics. | Stated range per grade |
| Chemistry | MgO, SiO2, CaO, Fe2O3 and Al2O3 control fired colour and reactivity. | Full oxide analysis by XRF |
| Heavy metals | Lead, arsenic, cadmium and mercury limits apply to cosmetic, pharma and food grades. | Per the applicable monograph or regulation |
| Asbestos | The main safety and liability issue in talc trade. | "Not detected" by named methods (XRD plus PLM or TEM) |
| Microbial count | Required for cosmetic and pharma use. | Total aerobic count, yeast and mould, pathogen absence |
| Oil absorption | Sets binder demand in paint and powder feel in cosmetics. | Stated in g/100 g |
| Bulk density | Affects feeding, dust and how many tonnes fit in a container. | Loose and tapped values |
Asbestos testing and 2026 compliance
Talc and asbestos minerals sometimes form in the same geological settings. A lot from the wrong part of a deposit can carry trace asbestos fibres. For cosmetic, pharmaceutical and food buyers, asbestos data is the first document to check, not the last.
| Regulator or body | Position | Date |
|---|---|---|
| IARC (WHO) | Classified talc as "probably carcinogenic to humans" (Group 2A). The evaluation covered talc without asbestos. | July 2024 |
| US FDA | Proposed mandatory asbestos testing for talc in cosmetics under MoCRA, then withdrew the proposal after public comment. FDA still has to issue a new rule under MoCRA section 3505. | Proposed Dec 2024, withdrawn 28 Nov 2025 |
| USP | Revised Talc monograph with new chapter <901> Detection of Asbestos in Pharmaceutical Talc, using XRD and PLM. | Official 1 June 2026 |
| EU (ECHA RAC) | Recommended classifying talc as a Category 1B carcinogen (H350) and STOT RE 1 (H372). The European Commission decides whether to adopt. | RAC opinion 2025 |
| Great Britain (HSE) | Did not classify talc as a carcinogen. Agreed on lung toxicity from repeated inhalation. | Reported Jan 2026 |
How asbestos testing works
- XRD (X-ray diffraction) screens the mineral make-up of the powder. Fast, but limited at very low fibre levels.
- PLM (polarized light microscopy) identifies fibres by optical properties. Required with XRD under USP <901>.
- TEM (transmission electron microscopy) finds the smallest fibres. The most sensitive method and the most expensive.
An "asbestos-free" statement without a method, a detection limit, a laboratory name and a lot number carries little weight. For cosmetic or pharma talc, ask for a lot-linked report using XRD plus PLM at minimum, and TEM where your market or customer expects it.
Talc prices: what drives the cost per tonne
Talc has no exchange-traded benchmark. Prices are set lot by lot between buyer and seller. The best public reference is the USGS average milled talc price in the United States.

| Year | 2021 | 2022 | 2023 | 2024 | 2025 (est.) |
|---|---|---|---|---|---|
| US$ per tonne | 322 | 298 | 333 | 331 | 330 |

Six factors that move a talc quotation
Landed cost per tonne = FOB price + freight + insurance + duty + port and inland chargesExample: a US$260 FOB offer with US$95 freight lands at US$355 plus local costs. A US$300 CFR offer from a nearer port lands cheaper before duty. Always convert quotes to the same Incoterm and destination.
Natural talc (HS 2526.10 not crushed, HS 2526.20 crushed or powdered) enters the United States duty-free. Check your own country's tariff for HS 2526 before you compare origins.

Source: USGS Mineral Commodity Summaries 2026. Thousand tonnes. Some countries report steatite or unspecified talc minerals.
- Plastics lead demand. In the US, plastics took 36% of talc in 2025, paint 19%, ceramics 17%, paper 12%, roofing 8% and rubber 2%.
- Pakistan and China supply most US imports. In 2025, Pakistan supplied about 49% of US talc imports, China about 27% and Canada 20%. Much Pakistani talc is mined in Afghanistan and milled in Pakistan.
- Traditional uses are shrinking. Water-based paints, lower-talc ceramic bodies and chemical pitch control have cut talc use in paint, ceramics and paper.
- Compliance is reshaping cosmetic demand. IARC's 2024 classification, the EU classification process and litigation risk push cosmetic buyers toward fully documented, lot-tested talc.
How to buy talc powder: step by step
- Name the end use. Cosmetic, pharma, food, plastics, paint, paper, ceramics or rubber. The use decides the grade and documents.
- Set the specification. Particle size with method, whiteness with method, chemistry, moisture and any regulatory limits.
- Request a sample and lot CoA. Test the sample in your own process. A data sheet alone does not prove fit.
- Check asbestos and safety data. Lot-linked asbestos report, SDS and, for the EU, REACH status.
- Agree packing and Incoterm. Bags or jumbo bags, pallets, shrink wrap, FOB, CFR or CIF, named ports.
- Agree inspection. Pre-shipment sampling by an independent inspector and a named controlling laboratory.
- Start with a trial container. Confirm consistency before you commit to monthly volume.
- Lock change control. The supplier must notify you before any change of deposit, mill or treatment.

Frequently asked questions
What is the price of talc powder per tonne?
Talc has no exchange benchmark. The average US milled talc price was about US$330 per tonne in 2025, according to USGS. Coarse industrial grades sell below that average. Micronized, high-white, cosmetic and pharmaceutical grades sell well above. Freight is a large share of the delivered price, so compare offers on landed cost.
What are the main grades of talc?
The main grades are cosmetic, pharmaceutical, food, plastics, paint and coatings, paper, ceramics, rubber and agricultural talc. Each grade differs in particle size, whiteness, purity, chemistry and testing.
What is the difference between cosmetic and industrial talc?
Cosmetic talc is micronized, high-white and tested on each lot for asbestos, heavy metals and microbes. Industrial talc is specified for performance in plastics, paint, paper, ceramics or rubber and does not need cosmetic testing.
What does 325 mesh talc mean?
325 mesh refers to a sieve with 45 micron openings. A 325 mesh talc passes mostly through that sieve, with a stated residue limit. Finer grades are sized by laser diffraction and quoted as D50 and D97 values.
How do I know talc is asbestos-free?
Ask for a lot-linked test report naming the method, detection limit and laboratory. XRD plus PLM is the minimum under the revised USP talc monograph. TEM is the most sensitive method.
Is talc classified as a carcinogen?
IARC classified talc as probably carcinogenic to humans (Group 2A) in July 2024. In the EU, ECHA's risk committee recommended a Category 1B carcinogen classification in 2025, with the European Commission still to decide. Great Britain's HSE did not classify talc as a carcinogen.
Which countries produce the most talc?
India and China lead world production, with about 1.5 and 1.3 million tonnes in 2025. Brazil, the United States, Korea, France, South Africa and Turkey follow.
What is the HS code for talc?
Natural talc falls under HS 2526. HS 2526.10 covers talc that is not crushed or powdered, and HS 2526.20 covers crushed or powdered talc. Both enter the United States duty-free.
How much talc fits in a 20ft container?
A 20ft container usually holds about 18 to 25 tonnes of bagged talc, depending on bulk density, bag type and pallet use.
