Diatomite
Diatomite from Qingdao Chuanyi Diatomite Co., Ltd is a natural amorphous silica product derived from fossilized diatom shells, with SiO2 content ranging from 80% to 95%. The material is processed into fine powder with controlled particle size distribution, suitable for filtration, insulation, and agricultural uses. It is categorized into food grade, technical grade, and industrial grade, each with distinct purity and application parameters.
The product is manufactured in Shandong Province using raw materials from domestic diatomite mines. Processing includes washing, drying, and milling without calcination for food-grade variants. The material is non-toxic, chemically inert, and has a bulk density of 0.3 to 0.5 g/cm³. It is designed for consistent performance in liquid filtration systems and as a thermal insulator in construction materials. The listing does not specify whether the material is treated for low dust or anti-caking properties.
This diatomite is purchased by manufacturers in water treatment, oil refining, and food processing industries, particularly in Asia and North America. It is packaged in 25kg woven polypropylene bags or bulk containers. Trade terms are typically FOB Qingdao, with payment via T/T or L/C. MOQ is not stated but is negotiable for bulk orders. Buyers should request grade-specific test reports to confirm suitability for their application, especially if used in regulated sectors.

Sourcing Diatomite from Qingdao Chuanyi Diatomite Co., Ltd - China Import Guide
Before ordering diatomite from Qingdao Chuanyi Diatomite Co., Ltd, verify the exact grade and SiO2 content per batch via a recent certificate of analysis. Confirm whether the material is calcined or uncalcined, and request heavy metal and microbial test results if used in food or agricultural applications. Do not accept product without lab documentation, even if labeled as food grade.
Logistics are typically FOB Qingdao, with standard transit times of 20 to 35 days to global ports. Incoterms must be clearly defined in writing, and payment is usually via T/T or L/C. Lead time is not stated; request a production schedule and packing date. Confirm packaging type - woven bags or bulk containers - and whether moisture barriers are used. Ensure the supplier provides export customs clearance documentation.
Quality checks should include sampling from multiple bags, testing for moisture, particle size, and insoluble residue. Request a pre-shipment inspection report from a third-party lab such as SGS or Intertek. Retain samples for post-arrival testing, especially for regulated applications. Documentation must include a batch-specific certificate of analysis, packing list, and material safety data sheet. Inspect containers for moisture damage upon arrival.
