Import Bht — Buy in Bulk from Supplier in China

BHT (Butylated Hydroxytoluene, CAS 128-37-0) is a synthetic phenolic antioxidant supplied by Shanghai xuanyi chemical from their location in Shanghai's Jinshan district. The product offered has a melting point of 69.0-70.0 degrees Celsius, which sits within the narrow range indicative of high-purity material suitable for food-grade and technical applications. It is packaged in kraft paper outer layers with a plastic woven bag incorporating an inner plastic lining, providing moisture and contamination barriers during storage and transport. The declared net weight is 25 kg per bag, a standard industrial unit for antioxidant distribution to compounders and formulators.

The chemical structure of BHT features a 2,6-di-tert-butyl-4-methylphenol configuration, functioning as a primary antioxidant through hydrogen donation to interrupt free radical chain reactions. Typical industrial grades range from technical grade (approximately 99.0% purity) to food/pharmaceutical grade (99.5% minimum, often exceeding 99.8% with specified impurity limits). The supplier's description references use in food preservation, cosmetics, and pharmaceuticals, implying food-grade availability, though buyers should explicitly confirm which grade is offered and whether it meets FCC, USP, or EP monograph requirements. Common residual solvents, heavy metals, and phenolic impurity specifications should be requested.

Primary applications span polymer stabilisation (polyethylene, polypropylene, rubber), food and feed preservation (fat-containing products, cereals, packaging materials), cosmetic formulations (oils, waxes), and industrial lubricants. The compound's effectiveness depends on solubility compatibility with the substrate, processing temperature stability, and regulatory acceptance in the target market. Buyers should confirm with Shanghai xuanyi chemical: the exact purity grade and corresponding certification, whether batch-specific certificates of analysis are provided, the manufacturing method (Friedel-Crafts alkylation of p-cresol with isobutylene is standard), and any restrictions on food-contact or pharmaceutical use in destination markets.

Shanghai xuanyi chemical operates from No. 675 Yuanjing Road, Room 2315, Shanghai 201325, China. The address places them in Shanghai's Jinshan district, an area with significant chemical industry presence. The supplier holds an imported tier and harbor trust tier designation, suggesting some form of cross-border trading authorisation or import-export licence. Their response rate shows 0.00 percent with zero average response hours, indicating that platform-mediated communication has not yet generated measurable engagement. No information is provided about year of establishment, registered capital, warehouse facilities, or quality management system certification.

The supplier's product description positions BHT across food, cosmetic, pharmaceutical, and industrial sectors, though the specific grades and certifications available are not detailed in the source material. The description contains references to ISO and FDA certification and flexible MOQ options, but these claims should be treated as unverified marketing statements requiring independent confirmation. Buyers should request copies of current ISO 9001 and any food safety management system certificates, together with FDA facility registration details if US market supply is intended. The lack of response history suggests direct outreach through alternative channels may be necessary to establish trading terms and verify operational capacity.
