Buy & Import Silica fume from Tianjin Xuchuang Trading Co., Ltd. - Wholesale Supply

Tianjin Xuchuang Trading Co., Ltd. supplies industrial‑grade silica fume produced as an amorphous silicon dioxide (SiO₂) by‑product of silicon metal manufacturing. The material contains silicon dioxide in excess of 85 % by weight and is supplied in bulk or 25 kg paper‑bag packaging. Particle size distribution is centred below 0.2 µm, giving a high specific surface area that drives pozzolanic activity. Typical industry specifications list a bulk density of about 2.2 g cm⁻³ and moisture content below 1 %. Silica fume of this grade is commonly used to replace 5‑15 % of cement in high‑strength concrete mixes. Its fine particles fill voids in the cement matrix, improving compressive strength and resistance to chloride ingress. Construction chemical manufacturers and precast concrete producers in China and abroad source the product under FOB or CIF terms. Orders can be placed in bulk quantities, with packaging chosen to suit project logistics. The supplier’s harbour trust tier indicates verification of export capability, although response metrics are currently unavailable. Buyers should confirm exact MOQ, lead time and payment conditions directly with the supplier before contracting.

Frequently Asked Questions About Silica fume from Tianjin Xuchuang Trading Co., Ltd.
The supplier specifies that the SiO₂ content exceeds 85 % by weight. Buyers should request a certificate of analysis to verify the exact percentage for each batch.

Sourcing Silica fume from Tianjin Xuchuang Trading Co., Ltd. - China Import Guide

Before placing an order with Tianjin Xuchuang Trading Co., Ltd., importers should verify the supplier’s harbour‑level trust tier and request up‑to‑date certificates of analysis for silica fume. Confirm that the SiO₂ content, particle size distribution and moisture levels meet the project specifications, and ask for a sample if possible. Because the platform data show no recorded response activity, establishing a direct communication channel and clarifying minimum order quantities is essential.

Tianjin’s port facilities serve as the primary loading point for bulk or bagged shipments, so buyers should confirm the exact port of discharge and the preferred incoterm, whether FOB or CIF. Lead‑time estimates are not disclosed in the listing; request a production schedule and shipping timeline to align with project milestones. Payment terms are typically negotiated on a letter‑of‑credit basis, but the importer must agree on the specific conditions with the supplier.

Because silica fume is a fine powder, proper storage and handling are critical to maintain its pozzolanic activity. Importers should arrange for third‑party inspection at the loading port and obtain a certificate of compliance covering moisture, loss on ignition and pH. Documentation such as the material safety data sheet, test reports and the supplier’s ISO/SGS certificates should be reviewed before customs clearance to avoid delays.
