Minerals & Industrial Materials
Industrial buyers and project owners sourcing silica sand, quartz and other mineral inputs against chemistry, sizing, licence and logistics requirements.
Typical requirement
- Volume
- Trial lot through long-term bulk programme
- Key parameters
- SiO₂, Fe₂O₃, moisture and particle-size distribution
- Evidence
- Representative COA plus documentary due diligence
- Shipment
- Bulk, jumbo bag or container depending on grade
- Commercial status
- Subject to source, allocation and export confirmation
Sector context
Sourcing for minerals & industrial materials
A mineral offer is only meaningful when chemistry, particle size, test method, source, annual availability and legal documentation refer to the same material and operating route.
We structure buyer requirements, coordinate documentary review and sampling, and align logistics with loading-point and destination constraints before commercial discussions are treated as firm.
Documents supplied by counterparties are passed through for verification by the relevant professional or authority. Tanah Raya does not present third-party permits, reserves or export approvals as its own.

Buying criteria
What decides acceptance in this sector
These are the parameters we build a specification around, because they are the ones that determine whether a lot is usable.
- 01
Chemistry on a stated method
SiO₂, Fe₂O₃, moisture and other required parameters tied to representative sampling.
- 02
Sizing and processing route
Washed, dried, screened or milled presentation aligned to the buyer's process.
- 03
Legal and documentary route
Source, licence, allocation and export-document status reviewed before contracting.
- 04
Logistics feasibility
Mine-to-port movement, loading point, draft and shipment size assessed with the specification.
Failure modes
Where sourcing goes wrong here
Screening is built around these, because they are the problems that actually recur in this sector.
Certificate not representative of the offered lot
Sampling provenance and test date are checked before a result is relied on.
Volume detached from logistics
Annual figures are tested against production, stockpiling and port capacity.
Third-party approval presented as ownership
Document issuer, holder, validity and relevance are recorded without overstating Tanah Raya's role.
Commodities we source for this sector
Other sectors
Healthcare Infrastructure & Major Projects
Project owners, hospital operators and appointed contractors coordinating construction packages and medical-equipment procurement against an approved scope and RAB.
Edible Oils & Agricultural Commodities
Importers, distributors and food manufacturers sourcing bulk palm, sunflower, soybean and related oils on programme volumes and documented commercial terms.
Energy & Biomass
Power generation, industrial steam and process heat operations buying solid biomass fuel against calorific value, moisture and ash parameters.
Horticulture & Growing Media
Professional growers, substrate manufacturers and garden distribution buying coir-based growing media against EC, pH and expansion parameters.
Manufacturing & Industrial Inputs
Production businesses buying raw material to a defined input specification, where an out-of-spec lot stops a line rather than merely disappointing.
Food & Beverage
Food manufacturers and ingredient buyers sourcing agricultural commodities where documentation, hygiene and traceability requirements are strict.
Water & Air Filtration
Activated carbon producers and filtration manufacturers buying coconut shell charcoal as feedstock against fixed carbon and ash parameters.
