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

China‑based Zhengzhou Haixu Abrasives Co., Ltd. lists 169 active products across its catalogue. The listings include a variety of abrasive minerals and compounds such as white fused alumina (HS 2818.12), brown fused alumina (HS 2818.10), chromite sand and concentrate (HS 2610.00), natural almandine garnet sand for water‑jet cutting (HS 2513.20), green silicon carbide (HS 2849.20), coated abrasives on polyester backing (HS 6805.10) and aluminum powder (HS 7603.20). Each entry specifies the material composition, for example brown fused alumina with Al2O3 purity between 92‑96 % or chromite sand with 46 % Cr2O3. The catalogue also mentions specialty items such as ceramic sand for glass blasting and lapping white corundum micropowder, although no HS code is supplied for those particular lines.

The product list reflects a focus on industrial abrasive applications, including sandblasting, grinding, polishing and metalcasting. Items such as 30/60 mesh garnet abrasive (HS 2513.20) target water‑filter media, while various grain‑size specifications of white and brown fused alumina (2‑5 mm, 25‑55 mesh) serve sandblasting and refractory uses. The inclusion of silicon carbide (SiC) grades with minimum 98.5 % purity expands the range into high‑hardness cutting and grinding tools. Overall, the catalogue spans both synthetic and natural abrasive minerals, each tied to a specific HS‑code family that defines customs treatment.

Product Range and Specialties of Zhengzhou Haixu Abrasives Co., Ltd.

The catalogue groups products by material family: fused alumina (white and brown), chromite sand, garnet, silicon carbide and aluminum powder. Within the fused alumina segment, typical industry grades range from ICUMSA‑like purity 99 %+ for polishing grades to 92‑96 % for general sandblasting, with particle sizes expressed in mesh or millimetres. Garnet abrasives are commonly supplied at 30‑60 mesh for filtration media and at finer grades for water‑jet cutting, while silicon carbide grades above 98 % SiC are used where high hardness (Mohs 9‑9.5) is required. Chromite sand used in foundries is usually specified by Cr2O3 content (around 46 %) and low silica to meet metal‑casting standards. Aluminum powder (WA grade) typically meets a minimum 99.7 % Al content and is shipped in bulk drums or 25 kg bags. These specifications align with standard industry data sheets and allow buyers to match performance requirements.

Trade and Export Information - Zhengzhou Haixu Abrasives Co., Ltd.

Abrasive minerals from China are exported primarily to automotive, metal‑fabrication, construction and electronics manufacturers in Southeast Asia, the Middle East and Europe. The HS‑code families represented (2818, 2610, 2513, 2849, 6805, 7603) trigger standard customs duties and often require a Certificate of Origin and an ISO 9001 quality‑management certificate, which buyers typically request before shipment. For chromite sand and silica‑based abrasives, environmental compliance such as REACH registration and MSDS documentation are common prerequisites. Shipping is usually performed in 20‑ft or 40‑ft containers, with bulk powders packed in sealed drums and granular abrasives in multi‑layered polypropylene bags. Common Incoterms are FOB Zhengzhou or CIF destination port, allowing buyers to arrange inland transport and customs clearance.

Sourcing from Zhengzhou Haixu Abrasives Co., Ltd. - Buyer Guidance

When sourcing from Zhengzhou Haixu, buyers should request the latest Material Safety Data Sheet (MSDS) and a third‑party test report confirming purity, particle‑size distribution and hardness for each abrasive grade. For fused alumina, a grain‑size analysis (mesh or mm) and a loss‑on‑ignition (LOI) value help verify the claimed specifications. Verify that the supplier can provide ISO 9001 certification or equivalent quality‑system documentation, and confirm the packaging format (e.g., 25 kg bags for bulk alumina, 1 ton drums for silicon carbide). Clarify the minimum order quantity, lead time and whether the shipment will be under FOB or CIF terms, and ensure that the HS code on the commercial invoice matches the product description.

What abrasive grades does Zhengzhou Haixu list in its catalogue?

The catalogue includes white fused alumina (≥99 % Al2O3, HS 2818.12), brown fused alumina (92‑96 % Al2O3, HS 2818.10), natural almandine garnet sand (97‑98 % purity, HS 2513.20), green silicon carbide (≥98.5 % SiC, HS 2849.20), and chromite sand with 46 % Cr2O3 (HS 2610.00).

Are there specific particle‑size specifications for the sandblasting products?

Yes. The sandblasting products are described by mesh ranges such as 25‑55 mesh for brown fused alumina and 2‑5 mm for white fused alumina, as well as 30/60 mesh for garnet sand used in water‑filter media. These sizes are standard industry metrics for abrasive flow control.

What documentation should a buyer request before placing an order?

Buyers should ask for an up‑to‑date MSDS, a third‑party purity and particle‑size test report, the supplier’s ISO 9001 or equivalent quality‑management certificate, and a Certificate of Origin matching the HS code. These documents are routinely required for customs clearance and quality verification.

Which HS codes are associated with the listed products?

The main HS codes are 2818.10 for brown fused alumina, 2818.12 for white fused alumina, 2610.00 for chromite sand and concentrate, 2513.20 for natural garnet sand, 2849.20 for green silicon carbide, 6805.10 for coated abrasives, and 7603.20 for aluminum powder. Each code determines the tariff treatment and required paperwork.

What are typical incoterms used for shipping these abrasives from China?

Exporters from China commonly offer FOB from the Zhengzhou port area or CIF to the buyer’s destination port. The choice influences who arranges inland transport, insurance and freight charges.

What are the usual packaging formats for bulk abrasive orders?

Bulk fused alumina and silicon carbide are typically packed in sealed 25 kg polypropylene bags or 1‑ton steel drums, while garnet and chromite sands are often loaded in multi‑layered bulk bags (up to 1 ton) inside a 20‑ft or 40‑ft container. Proper sealing prevents moisture ingress and contamination.

Is a minimum order quantity (MOQ) specified for these products?

While the catalogue does not list a fixed MOQ, buyers generally encounter MOQs ranging from 10 tons for bulk alumina powders to 5 tons for coated abrasives, depending on the product and packaging. The supplier can confirm exact quantities during quotation.

What lead times are typical for these abrasive products?

Lead times for standard grades such as white or brown fused alumina are usually 15‑30 days from order confirmation, whereas specialty silicon carbide or coated abrasive orders may require 30‑45 days due to additional processing or quality checks.
