About Shanghai xuanyi chemical - Chemical Supplier in China

Shanghai xuanyi chemical is based in China and currently lists six active products in its catalogue. The product portfolio includes the antioxidant butylated hydroxytoluene (BHT), the inorganic oxidizer potassium monopersulfate, and four specific antioxidant grades labelled Antioxidant10, Antioxidant215, Antioxidant225 and Antioxidant1076. Each entry is recorded under the supplier’s chemical catalogue without additional sub‑categories. The listing reflects a focus on specialty chemicals used in food preservation, polymer stabilization and industrial cleaning applications. The supplier’s tier is classified as imported with a harbor trust rating, indicating it operates through established trade channels into overseas markets.

The six chemicals cover both organic and inorganic categories commonly referenced in HS Chapter 29 for organic chemicals and Chapter 28 for inorganic chemicals. BHT is a phenolic antioxidant frequently supplied in powder form with typical purity levels above 99 %. Potassium monopersulfate is an oxygen‑rich oxidizing agent often supplied as a granular or crystalline solid with purity around 95‑98 %. The four antioxidant grades are identified by internal numbers and are generally marketed for specific performance criteria such as low‑temperature stability or high‑temperature resistance. No further company‑specific details such as founding year or production capacity are provided in the source data.

Product Range and Specialties of Shanghai xuanyi chemical

The catalogue lists BHT, potassium monopersulfate and four numbered antioxidant products. In the broader chemical industry, BHT is supplied in grades ranging from technical (≈96 % purity) to pharmaceutical (≥99 % purity) and is evaluated against specifications such as ICUMSA color and peroxide value. Potassium monopersulfate is typically offered in standard (≥95 % purity) and high‑purity (≥98 % purity) grades, with specifications for active oxygen content and moisture. Antioxidant grades such as Antioxidant10, 215, 225 and 1076 are usually distinguished by their thermal stability, oil‑solubility and polymer compatibility, and buyers often request data sheets that list parameters like flash point, cloud point and oxidative induction time. The supplier’s product list aligns with these common classifications, providing a base for buyers to match required specifications.

Industry practice for these chemical categories includes providing a Certificate of Analysis (COA), Material Safety Data Sheet (MSDS) and, where applicable, compliance documents for food‑contact (e.g., FDA GRAS) or industrial standards (e.g., REACH registration). Buyers typically compare the listed grades against their own formulation requirements, focusing on purity, moisture content and allowed impurity limits.

Trade and Export Information - Shanghai xuanyi chemical

China is a major exporter of both organic antioxidants and inorganic oxidizers, with shipments frequently directed to Southeast Asia, Europe and North America. Export logistics for powdered or granular chemicals often use 25 kg drums, 1 ton IBCs or bulk 20 ft containers, depending on order volume. Common HS code families for the listed items are 2915 for phenolic antioxidants like BHT and 2844 for inorganic peroxy compounds such as potassium monopersulfate. Import regulations usually require a COA, MSDS and, for food‑related uses, compliance with local food‑safety standards. Buyers should also be aware of customs duties that may apply under the respective HS chapters and any anti‑dumping duties that can affect Chinese chemical imports.

Typical buyers of these chemicals include food processors seeking lipid‑stabilization, polymer manufacturers requiring thermal stabilizers, and water‑treatment firms using strong oxidizers. While the supplier’s specific target markets are not listed, exporters from China often serve distributors and OEMs in the United States, the European Union, Japan and the Middle East. Standard Incoterms such as CIF or FOB are used, with containerized freight being the most cost‑effective for bulk orders.

Sourcing from Shanghai xuanyi chemical - Buyer Guidance

When sourcing from Shanghai xuanyi chemical, request a recent COA for each product to verify purity, moisture and any residual solvents. An up‑to‑date MSDS should be obtained to assess handling, storage and transport requirements, especially for the oxidizing agent potassium monopersulfate which may have specific segregation rules. Buyers should confirm whether the antioxidant grades meet any relevant regulatory lists (e.g., EU food‑additive register or US FDA GRAS) if the intended use is food‑related.

What chemical products does Shanghai xuanyi chemical list in its catalogue?

The catalogue contains six items: BHT (butylated hydroxytoluene), potassium monopersulfate, and four antioxidant products identified as Antioxidant10, Antioxidant215, Antioxidant225 and Antioxidant1076.

In what forms are BHT and potassium monopersulfate typically supplied?

BHT is usually supplied as a fine powder or granules, while potassium monopersulfate is offered as granular or crystalline solid, both packaged in 25 kg drums, 1 ton IBCs or bulk containers.

Which documents should a buyer request before purchasing?

Buyers should request a Certificate of Analysis, a Material Safety Data Sheet, and, where applicable, compliance certificates such as FDA GRAS or REACH registration for the specific product.

What are common purity specifications for the listed antioxidants?

Industry standards often require BHT purity of 99 % or higher and antioxidant grades with purity between 95 % and 99 %, depending on the intended application.

What shipping terms are commonly used for these chemicals from China?

Exporters typically use Incoterms like FOB Shanghai or CIF destination port; containerized freight in 20‑ft or 40‑ft containers is standard for bulk shipments.
