Silica fume
Silica fume offered by Xiamen Yu Lin Trade Co., Ltd is an amorphous silica powder (SiO2) produced as a by‑product of ferrosilicon and silicon metal manufacturing. The material typically contains more than 85 % SiO2 by weight and is available in both densified and undensified forms, with a median particle size around 0.15 µm. It is shipped in bulk bags or mega‑bags, allowing large‑scale deliveries for construction projects.
Typical industry specifications include a specific surface area exceeding 20 000 m² kg‑1, bulk density of roughly 600 kg m‑3 for the densified product (about 300 kg m‑3 for the undensified version) and moisture content kept below 1 %. These properties give the fume its high pozzolanic activity, which is essential for high‑performance concrete, bridge decks, marine structures and industrial flooring where durability and low permeability are required.
Buyers are generally concrete producers, precast manufacturers and contractors engaged in infrastructure projects. The product is commonly supplied in bulk bags up to one tonne or in larger mega‑bags, and trade terms such as incoterms and payment conditions should be negotiated directly with Xiamen Yu Lin Trade Co., Ltd before finalising any purchase.

Silica fume (microsilica) is a highly reactive pozzolanic material widely used as a concrete additive to achieve exceptional compressive strength and durability in high-performance construction projects. This ultra-fine amorphous silica powder with SiO2 content typically above 85% is essential in bridges, marine structures, and industrial floors where chloride resistance and reduced permeability are critical. Sourced primarily from ferrosilicon and silicon metal production, it is available in densified or undensified form and traded globally in bulk bags or mega bags for import/export supply chains.

Sourcing Silica fume from Xiamen Yu Lin Trade Co., Ltd - China Import Guide
Confirm the SiO2 content, specific surface area and moisture level by obtaining a recent certificate of analysis before placing an order. Ensure the grade (densified or undensified) matches the performance requirements of your concrete mix design.
Discuss shipping arrangements early: agree on the appropriate incoterm, verify the loading capacity for bulk bags or mega‑bags, and ask the supplier about typical lead‑time from order confirmation to vessel departure. Clarify payment terms such as letter of credit or advance payment to avoid surprises.
Arrange for an independent inspection at the loading port or request pre‑shipment laboratory test reports. Secure the material safety data sheet, certificate of analysis and any relevant customs documentation to satisfy Chinese export regulations and the import requirements of your destination country.
