Portpro Duct Co. Ltd. supplies natural quartz composed of silicon dioxide (SiO2) sourced in Thailand. The material is offered with purity levels ranging from 99.5 % to 99.999 % as stated in the supplier’s specification. Available physical forms include lump, grain and powder, and the typical export packaging is 25 kg paper bags or 1 tonne jumbo bags. The supplier’s address is 41/14 Nangkana Chum Phae, Khon Kaen 40130, Thailand, and it is listed under the harbor trust tier.
In the broader market quartz of similar purity is classified into semiconductor, optical and industrial grades, with the highest grades demanding impurity levels below 0.001 %. Typical powder grades are milled to particle sizes between 10 µm and 200 µm, which matches the requirements for thin‑film solar cells and precision optics. Bulk density for dry quartz is commonly about 2.65 g/cm³, a figure that influences container loading calculations. The supplier notes that quartz is non‑conductive, heat‑resistant and chemically inert, properties that underpin its use across electronics and glass manufacturing.
Primary buyers include manufacturers of semiconductors, solar photovoltaic modules and advanced glass for architectural applications. Importers should confirm the minimum order quantity, preferred incoterm and any required certifications directly with Portpro Duct Co. Ltd. before placing a contract. Because response statistics show a 0 % reply rate, it is advisable to use a verified third‑party agent or request a formal quotation to ensure communication reliability.

Portpro Duct Co. Ltd. is located at 41/14 Nangkana Chum Phae, Khon Kaen 40130, Thailand. It is listed with a harbor trust tier on the platform, indicating a mid‑level verification status. The supplier’s response metrics show a 0 % reply rate and no recorded average response time, suggesting limited direct communication. Its current catalogue lists natural quartz (SiO2) with purity specifications and packaging options.
The profile does not disclose minimum order quantities, price lists, or specific certifications such as ISO or CE, so buyers must request these details explicitly. Portpro Duct Co. Ltd. focuses on bulk export of quartz for industrial applications rather than retail distribution. Prospective importers are encouraged to verify the supplier’s export licences and to obtain a sample for laboratory analysis before committing to large volumes.
High purity Silicon Dioxide (SiO2) quartz is a critical industrial mineral sourced globally for applications in electronics, semiconductors, solar PV, and advanced glass manufacturing. Available in lump, grain, and powder forms with purity levels from 99.5% to 99.999% for high-tech use. Quartz for semiconductor and fiber optic applications commands premium pricing due to stringent purity requirements. Widely traded internationally with major origins including Brazil, Norway, USA, and India, typically packed in 25kg bags or 1MT jumbo bags for export.

Before placing an order, the importer should verify the quartz purity, particle size and form against the supplier’s certificate of analysis, and confirm that the packaging meets the handling requirements of the destination facility. It is also prudent to request a small trial shipment or sample to test compatibility with the intended manufacturing process. Because the supplier’s response rate is recorded as zero, using a third‑party verification service can reduce the risk of miscommunication.
Logistics for bulk quartz from Thailand typically involve sea freight in 20‑ft or 40‑ft containers, with loading plans based on the standard bulk density of 2.65 g/cm³. Lead times are not disclosed by the supplier, so the buyer should ask for an estimated production and shipping schedule before finalising the contract. Common incoterms such as FOB Laem Chabang or CIF Bangkok should be negotiated, and payment terms often range from 30 % advance to balance on sight‑letter of credit.
Quality assurance normally includes an independent laboratory test for impurity levels, moisture content and particle size distribution, accompanied by a Certificate of Analysis and, where required, compliance with ISO 9001 quality management. Importers are advised to appoint a pre‑shipment inspection
