About Sichuan Hpm Co., Ltd. - Industrial Chemicals Supplier in China

Sichuan Hpm Co., Ltd. operates from Sichuan province in China and lists five active products in its catalogue. All five items are high‑purity elemental chemicals with a stated purity of 99.999 % (commonly referred to as 5N grade). The catalogue groups these materials under the broader categories of Chemicals & Allied Products and Industrial Chemicals, matching the supplier’s declared top categories. Each product is described by its chemical name - Selenium, Bismuth, Tellurium, Cadmium and Gallium - without additional specifications such as packaging size or HS codes. The supplier’s trust tier is listed as “harbor”, indicating a moderate level of verification within the platform’s rating system.

The product list focuses exclusively on metallic elements that are typically required in semiconductor manufacturing, alloy research and specialty medical applications. No further details on production capacity, certifications held or client references are provided in the supplied data. The catalogue’s five‑product count reflects a narrow but technically specific offering within the industrial chemicals market segment.

Product Range and Specialties of Sichuan Hpm Co., Ltd.

The five listed chemicals represent the 5N purity level that is standard for research‑grade and semiconductor‑grade materials. In the industry, 5N (99.999 %) is often the minimum accepted grade for high‑performance electronic components, while higher grades such as 6N (99.9999 %) are used for ultra‑pure applications. Typical specifications for these elements include limits on metallic and non‑metallic impurities, moisture content below 0.01 % and packaging in airtight, nitrogen‑purged containers to prevent oxidation. Buyers also expect a Certificate of Analysis (CoA) that details impurity profiles according to ASTM or ISO standards.

In the global market, high‑purity selenium, bismuth, tellurium, cadmium and gallium are sourced for uses such as photovoltaic cell production, thermoelectric devices, radiation shielding alloys and advanced solder alloys. Industry standards often reference ISO 9001 quality management, ISO 14001 environmental management and material‑specific ASTM methods (e.g., ASTM B595 for bismuth purity). While the supplier’s catalogue does not list certifications, these are the typical benchmarks buyers verify for comparable products.

Trade and Export Information - Sichuan Hpm Co., Ltd.

Exporters of high‑purity elemental chemicals from China commonly ship to North America, Western Europe and East Asia, where semiconductor fabs, research laboratories and specialty alloy manufacturers are concentrated. HS Chapter 26 (Mineral fuels, mineral oils and products of their distillation) and Chapter 28 (Inorganic chemicals) cover most of these elements, and customs authorities often request a detailed material safety data sheet (MSDS) and a certificate of conformity for each shipment. Standard Incoterms such as FOB or CIF are used, with containers or bulk drums selected based on the product’s sensitivity to moisture and oxidation.

Regulatory requirements for these metals include REACH registration for the European Union, the U.S. Toxic Substances Control Act (TSCA) for cadmium and other heavy metals, and RoHS compliance for end‑use in electronic equipment. Buyers typically request ISO‑based quality management certificates, third‑party analytical test reports (ICP‑MS or GD‑MS), and proof of compliance with local hazardous material handling rules. Chinese exporters often provide export licenses and customs declarations that reference the appropriate HS headings, facilitating smooth clearance in target markets.

Sourcing from Sichuan Hpm Co., Ltd. - Buyer Guidance

When sourcing from Sichuan Hpm Co., Ltd., buyers should ask for a recent Certificate of Analysis that lists the exact purity, impurity limits (e.g., Fe, Cu, Pb) and the analytical method used. A current Material Safety Data Sheet is essential for handling and transport, especially for cadmium, which is classified as a hazardous substance in many jurisdictions. Verify that the supplier can provide packaging that meets moisture‑barrier requirements, such as double‑sealed polyethylene bags or metal cans with nitrogen purge.

Typical minimum order quantities for 5N metals range from 0.5 kg to 5 kg, depending on the element and the buyer’s intended use. Lead times of 2‑4 weeks are common for laboratory‑grade batches, but larger bulk orders may require additional processing time. Prior to shipment, request a pre‑shipment inspection report or third‑party assay to confirm that the declared purity matches the actual product.

What purity levels does Sichuan Hpm Co., Ltd. offer for its elemental chemicals?

All five listed elements - Selenium, Bismuth, Tellurium, Cadmium and Gallium - are specified at 99.999 % purity, which corresponds to the 5N grade commonly required for semiconductor and research applications.

Are there any certifications listed for these products?

The supplied facts do not mention any certifications held by the supplier. Buyers should request copies of ISO 9001, ISO 14001 or other relevant quality certificates if they are required for the purchase.

Which documentation should be requested before placing an order?

Request a current Certificate of Analysis, a Material Safety Data Sheet, and any export permits or customs declarations that reference the appropriate HS chapter for inorganic chemicals.

What are the typical packaging methods for these high‑purity metals?

Industry practice is to ship in moisture‑proof, nitrogen‑purged containers such as sealed polyethylene bags, metal drums or airtight bottles to preserve the 5N purity during transit.

What are the common end‑use industries for these elements?

Selenium and tellurium are used in photovoltaic and thermoelectric devices, bismuth and gallium in specialty alloys and medical imaging, and cadmium in battery and radiation‑shielding applications.

Which markets does the supplier primarily export to?

While the facts do not list specific destinations, Chinese exporters of high‑purity metals typically serve North America, Europe and East Asian countries where semiconductor and advanced material manufacturing are concentrated.

What are the usual lead times and minimum order quantities?

Lead times of 2‑4 weeks are typical for laboratory‑grade quantities, with minimum orders generally ranging from 0.5 kg to 5 kg depending on the element and buyer specifications.

Are there any special import regulations for these products?

Importers should verify REACH registration for the EU, TSCA compliance for the United States, and RoHS restrictions for products destined for electronic equipment, as these regulations commonly apply to high‑purity metallic chemicals.
