About Haixu Abrasives Co., Ltd - Abrasives Supplier in China

Haixu Abrasives Co., Ltd is based in China and currently lists 29 active products. The catalogue focuses on two main categories: Abrasives and Sandstones & Sands. Products are grouped under HS code 2818.10 for various forms of white fused alumina and corundum, and HS code 2513.20 for natural garnet sand. The listed items include White Fused Alumina, White Corundum of multiple grades, synthetic corundum for polishing, and garnet sand for water‑jet cutting.

The abrasive line concentrates on high‑purity aluminum oxide, with declared Al2O3 contents of 98.5 % to 99.5 % depending on the grade. Items specify particle‑size ranges such as 0‑1 mm grit, 3‑5 mm corundum, and micro‑powder for precision lapping. Several products reference industry designations like JIS 8000 and use terms such as “White Fused Alumina” or “Synthetic White Fused Corundum.” The garnet sand entries describe natural almandine type with mesh 80 and a typical chemical composition of Fe2O3 25‑33 %, SiO2 34‑38 %, Al2O3 17‑22 %. All products are presented without explicit certifications, leaving verification to the buyer.

Product Range and Specialties of Haixu Abrasives Co., Ltd

The catalogue lists a suite of white fused alumina products, each identified with Al2O3 purity of at least 99 % and marketed for grinding, polishing, lapping and refractory applications. In the global abrasive market, fused alumina grades are commonly classified by purity (99 %, 99.5 % and 99.8 %) and particle size, with standard specifications such as ISO‑based quality control and hardness around 9 on the Mohs scale. Synthetic white corundum products labeled “JIS 8000” meet the Japanese Industrial Standard for fine polishing abrasives. Micro‑powder variants typically have particle diameters below 10 µm and are used for precision surface finishing. Bulk grades like the 24#‑240# sand‑blasting corundum are supplied in coarse size ranges for surface preparation.

The garnet sand entries fall under HS 2513.20 and describe natural almandine garnet with an 80 mesh size and a chemical makeup of Fe2O3 25‑33 %, SiO2 34‑38 % and Al2O3 17‑22 %. In the water‑jet cutting industry, such garnet is the preferred abrasive due to its high fracture toughness and consistent grain size. Typical industry specifications require a minimum crush strength of 350 MPa and a bulk density around 3.8 g/cm³. Buyers often request certification of mesh consistency and a chemical analysis report to confirm compliance with ISO 14001 environmental standards.

Trade and Export Information - Haixu Abrasives Co., Ltd

China is one of the world’s largest exporters of aluminum‑oxide abrasives and natural garnet sand, supplying markets in North America, Europe and Southeast Asia. HS chapter 28 (2818.10) covers fused alumina and corundum, while chapter 25 (2513.20) covers natural garnet, and both codes are routinely examined by customs for certificate of origin and compliance with safety regulations. Importers of these materials typically require ISO 9001 quality‑management certification, and for EU destinations CE marking or REACH compliance may be requested. Refractory‑grade alumina also often needs to meet ASTM C618 specifications for high‑temperature performance.

Export shipments from China are commonly packed in 25 kg polypropylene bags for fused alumina and in 20 kg or 25 kg bags for garnet sand, then consolidated into 20‑foot or 40‑foot containers. Standard Incoterms used are FOB Shanghai or CIF destination port, with freight forwarders handling moisture‑proof sealing to meet the typical moisture content limit of less than 0.5 % for alumina powders. Buyers should anticipate container loading plans that accommodate the weight limits of 22 t per 20‑foot container for these dense abrasives.

Sourcing from Haixu Abrasives Co., Ltd - Buyer Guidance

Prospective buyers should request a detailed product data sheet that includes Al2O3 purity, particle‑size distribution (sieve analysis), bulk density, moisture content and hardness values. For garnet sand, a chemical composition analysis, mesh‑size certification and crush strength report are standard documents. Asking for the supplier’s ISO 9001 certificate and, where applicable, REACH or CE compliance documents helps verify that the products meet international regulatory expectations.

Before confirming an order, verify the packaging specifications such as bag weight, inner liner material and labeling for hazard classification. Requesting a sample batch for laboratory testing is common practice, especially to confirm abrasive performance against industry standards like JIS 8000 or ASTM C618. Clarify the agreed Incoterm, lead time - typically 15‑30 days for stocked grades - and any special handling instructions for fragile micro‑powders.

What abrasive product families are listed by Haixu Abrasives?

The supplier lists products under HS 2818.10, including White Fused Alumina, White Corundum of several grades, synthetic corundum for polishing and grinding, and micro‑powder for lapping.

What purity levels are specified for the white fused alumina items?

All fused alumina entries state an aluminum‑oxide (Al2O3) content of at least 99 % with some grades reaching 99.5 % or 99.8 % purity.

Which HS codes apply to the garnet sand products?

Garnet sand items are classified under HS 2513.20, which covers natural garnet and other abrasive mineral sands.

What certifications are commonly required when importing these abrasives from China?

Buyers usually request an ISO 9001 quality‑management certificate, and for EU markets may also need CE marking or REACH compliance documentation.

What are typical applications for the white corundum grades?

White corundum is widely used for sand‑blasting, glass‑ceramic surface preparation, wear‑resistant flooring, and precision polishing in optics and semiconductor sectors.

How is garnet sand typically packaged for export?

Export packs commonly use 20 kg or 25 kg polypropylene bags that are moisture‑sealed and then palletized for container loading.

What is a common minimum order quantity for the fused alumina products?

Stocked fused alumina grades are often sold in multiples of 25 kg bags, with a practical MOQ of one 20‑foot container (approximately 800 bags) for bulk orders.

What lead time should a buyer expect for a standard order of these abrasives?

Lead times usually range from 15 to 30 days from order confirmation, depending on stock availability and the selected Incoterm.
