Import Activated Bleaching Earth — Buy in wholesale FOB from Supplier in China

Shenzhen Aoheng Science & Technology Co., Ltd supplies an acid-activated bentonite clay engineered for decolorizing and purifying edible oils, biodiesel, and petroleum products. The material is an industrial-grade decolorizing earth with stated application across palm, soybean, sunflower, and mineral oil streams籍refining processes. The supplier indicates the product is available in various mesh sizes for filtration efficiency, though exact screen fractions are not listed in the source data. Its adsorption capacity targets color bodies, pigments, and broader contaminants rather than single-species removal.

The base material is acid-activated bentonite, a smectite clay treated with mineral acid to expand interlayer spaces and generate surface acidity. This activation protocol increases cation exchange capacity and creates Brønsted acid sites that bind polar pigments, phospholipid traces, and oxidation products. Standard industry practice treats raw bentonite with sulfuric or hydrochloric acid at elevated temperature, followed by washing, drying, and milling to specified particle distributions. Typical commercial grades achieve pH in the 2.5 to 4.5 range after activation, with free moisture content between 8 percent and 12 percent at point of packaging.

Buyers are primarily edible oil refiners, biodiesel producers, and lubricant manufacturers seeking to meet AOCS color specifications or similar regional standards. The supplier references ISO and SGS compliance in source material, though buyers should request current certificates of analysis for each batch. Packaging is not specified; standard export formats for Chinese-origin bleaching earth include 25 kg multiwall paper bags, 500 to 1,000 kg bulk bags, or loose bulk in container loads. Trade terms, MOQ, lead time, and precise incoterms must be confirmed directly with Shenzhen Aoheng Science & Technology Co., Ltd.

Shenzhen Aoheng Science & Technology Co., Ltd is registered at R912, B&h Plaza, 27 Nanhai Avenue, Shekou, Shenzhen 518067, in Guangdong Province, China. The supplier holds an imported tier designation and a harbor trust tier on the platform, with a response rate of 0.00 percent and an average response time of zero hours. These signals indicate limited or no recent engagement through platform messaging; buyers should treat direct contact as essential and should not rely on platform-only communication channels. No verified audit status, factory inspection report, or third-party certification details are present in the source profile.

The company positions itself as a provider of activated bleaching earth for industrial-scale refining operations, with product emphasis on acid-activated clay rather than natural or neutral earth variants. The listing does not state year of establishment, production capacity, number of employees, or specific client references. Buyers seeking supply continuity should request a company profile, business licence, and recent batch certificates of analysis before committing to trial orders. The supplier's location in Shenzhen provides proximity to Yantian and Shekou ports, which may offer logistical advantages for sea freight to Southeast Asian, Middle Eastern, and African markets.
