Import Barite — Buy in Bulk from Supplier in Hong Kong

Sinofrica Chemical Limited supplies barite (barytes), a barium sulfate mineral with the chemical formula BaSO4, from its Hong Kong base. The material is offered as ground fine powder for drilling mud weighting applications, and in fragment form for radiation shielding gravity wall construction. The standard packaging configuration is 25 kg or 50 lb net multi-wall paper bags, with bulk option of 1000 kg or 2000 lb supersacks. The specific gravity of drilling-grade barite typically falls between 4.1 and 4.3, though buyers should confirm the exact figure with Sinofrica Chemical Limited for this lot.

Barite for industrial use is classified by API (American Petroleum Institute) specifications or by chemical purity for non-drilling applications. API-grade barite must pass particle size distribution tests, with 97% minimum passing a 74-micron sieve and 90% minimum passing a 44-micron sieve. The material is chemically inert, insoluble in water, and resistant to acids and alkalis. Colour ranges from white to off-white or grey, depending on purity and trace mineral content. For paint, rubber and paper filler applications, brightness and low silica content are critical quality parameters. Barite ore is processed by crushing, washing, jigging and flotation to achieve the required specifications.

The primary buyers for this barite are oilfield service companies requiring drilling mud weighting agents, construction firms specialising in radiation shielding for medical and nuclear facilities, and manufacturers of paints, plastics and rubber goods. The 25 kg bag format suits smaller industrial users and distributors, while supersacks serve bulk consumers directly. Hong Kong's status as a free port with established logistics infrastructure supports re-export to Southeast Asian manufacturing centres and mainland China drilling operations. Buyers should verify Sinofrica Chemical Limited's current stock position, exact BaSO4 content, and whether the material is API-certified or general industrial grade before committing to shipment.

Sinofrica Chemical Limited operates from Flat/Room 502, Arion Commercial Centre, 2-12 Queen's Road West, Hong Kong 518000. The company's registered address places it in the Sheung Wan district, a long-established commercial and trading hub. Its supplier tier is classified as 'imported', indicating it sources material rather than manufacturing directly, and its trust tier is 'harbor', which is a baseline verification level. The response rate is recorded at 0.00% with zero average response hours, so buyers should not expect rapid email replies and should plan to follow up by telephone or through alternative channels.

The company profile does not state founding year, employee count, annual turnover, factory ownership, or named clients. No certifications such as ISO, API or REACH are mentioned in the available data. Sinofrica Chemical Limited appears to function as a trading entity focused on barite and potentially other industrial minerals, positioned to serve buyers seeking barium sulfate products through Hong Kong's port and logistics network. The listing provides basic product and packaging information but lacks detailed quality documentation or technical datasheets. Buyers should conduct standard due diligence including requesting material safety data sheets, certificates of analysis, and samples before placing substantial orders.
