Import Bentonite — Buy in wholesale FOB from Supplier in China

Zhejiang Huate Group supplies bentonite mined as natural smectite clay with montmorillonite as its dominant mineral phase, offered in sodium or calcium variants depending on end-use requirements. The material demonstrates exceptional swelling capacity and high absorption, with low grit content and consistent mesh sizing that suits industrial processing in drilling fluids, foundry sand binding, iron ore pelletizing, and environmental sealing. Available formats include bulk bags and loose bulk shipments, with trade terms referenced as FOB for international buyers.

The sodium grade typically exhibits superior swelling index and thixotropic behaviour in aqueous suspension, making it the preferred choice for oil and gas drilling muds where viscosity control and wall-cake formation are critical. Calcium bentonite, by contrast, finds stronger demand in foundry applications where green compressive strength and dry sand durability matter more than extreme swelling. Both grades respond to standard beneficiation processes such as drying, milling, and classification to achieve the particle size distribution required by API 13A for drilling-grade material or by individual foundry customers for AFS grain fineness targets. The geological origin in Chinese deposits generally yields a grey to greenish-grey colour, though colour is not itself a quality determinant.

Buyers span oilfield service companies, iron ore pellet plants, non-ferrous foundries, geosynthetic clay liner installers, and civil engineering contractors requiring waterproofing barriers. When engaging Zhejiang Huate Group, confirm the specific cationic type being quoted, the swelling volume in millilitres per two grams, and the methylene blue index as a proxy for montmorillonite content. Also verify whether the offered material has been tested to API 13A Section 9 or OCMA DFCP-4 standards, and whether the supplier provides certificates of analysis with each bulk lot.

Zhejiang Huate Group lists its address at No.441 Lin'tian Road, Lin'an, Hangzhou, 311300, China, placing the operation within Zhejiang Province in eastern China. The supplier holds a harbor trust tier on the platform, though its response rate currently registers at 0.00% with no recorded average response hours. This profile contains no disclosed years in operation, factory size, employee count, revenue figure, or named clientele, so any such claim would be fabrication. The listing focuses on bentonite as its principal export commodity, positioning the company as a mine-to-market clay supplier.

A buyer should treat the low response signal as a material risk factor and plan to follow up through multiple channels before relying on this source for time-sensitive procurement. The absence of quoted MOQ, exact lead time, or certification copies in the source data means these must be negotiated and documented directly. The supplier's location in Hangzhou suggests access to Ningbo or Shanghai port infrastructure for containerised or bulk vessel export, though the specific loading port should be confirmed. No secondary product lines are mentioned in the available profile.
