About Nanjing Herui International Co., Ltd. - Industrial Supplies Supplier in China

China hosts the supplier Nanjing Herui International Co., Ltd., which currently lists five distinct products in its catalogue. The active product count of five includes magnetic materials, segment magnets, a general pigment offering, mill scale, and iron‑oxide red pigment. Each product is classified under the broader industrial supplies segment, with the company also appearing in the titanium‑dioxide category in the platform hierarchy. The catalogue does not provide HS codes, so classification must be inferred from standard trade data for similar goods. The supplier is recorded as an imported tier with a harbor trust rating, indicating it operates through Chinese export channels.

The listed items represent typical industrial inputs: magnetic materials are raw or semi‑finished ferromagnetic compounds; segment magnets are pre‑shaped magnet sections used in assemblies; the pigment entry aligns with inorganic colourants such as iron‑oxide red; mill scale is a by‑product of steel rolling; and iron‑oxide red itself is a widely used red pigment in coatings. No additional company history, employee numbers, or revenue figures are supplied, and the description relies solely on the provided product names and category tags.

Product Range and Specialties of Nanjing Herui International Co., Ltd.

The catalogue shows five product types: magnetic materials, segment magnets, a generic pigment, mill scale, and iron‑oxide red. In the magnetic materials market, suppliers typically offer ferrite, neodymium‑iron‑boron (NdFeB), and samarium‑cobalt grades, with common specifications such as coercivity (Hc) between 800‑1200 kA/m for ferrite and energy product (BHmax) of 30‑45 MGOe for NdFeB. Segment magnets are usually supplied in standard lengths from 10 mm to 200 mm, thicknesses of 2‑10 mm, and surface finishes that meet ISO 9001 dimensional tolerance of ±0.1 mm. Pigments listed under industrial supplies often include iron‑oxide red with purity of 95‑99 % and particle size distribution of 5‑10 µm, while titanium‑dioxide grades (not listed but related) are commonly supplied as rutile with an ICUMSA 45 whiteness index. Mill scale is a ferrous by‑product containing 90‑95 % FeO/Fe₂O₃, used as a feedstock for steel recycling or as a filler in cement, typically packaged in bulk bags of 1 tonne.

Trade and Export Information - Nanjing Herui International Co., Ltd.

China’s export infrastructure for industrial supplies such as magnets, pigments, and steel by‑products is well‑established, with major ports in Shanghai, Ningbo and Tianjin handling containerized and bulk shipments. Buyers in Southeast Asia, the European Union and North America regularly import magnetic components for automotive and electronics assemblies, while pigments and iron‑oxide red are sourced for paints, coatings and plastics. Standard packaging includes antimagnetic polyethylene bags for magnet sections, 200 L steel drums or 25 kg polyethylene bags for pigments, and bulk bags for mill scale. Common Incoterms are FOB Shanghai or CIF Europe, and customs documentation normally requires a commercial invoice, packing list, and a certificate of origin. Buyers frequently request ISO 9001 quality system certificates, REACH registration for pigments, and MSDS for all chemical‑based products, though the supplier’s own certifications are not listed in the provided facts.

Sourcing from Nanjing Herui International Co., Ltd. - Buyer Guidance

When sourcing from this supplier, buyers should obtain a detailed product data sheet that specifies magnetic coercivity, energy product, or pigment purity and particle size as applicable. Requesting third‑party test reports - such as ASTM B443 for magnetic flux density or ISO 14040 for pigment colour‑fastness - helps verify compliance with industry standards. Buyers should also ask for REACH registration evidence for pigment items, an MSDS for mill scale, and a COA for iron‑oxide red to confirm iron content and colour specifications. Verifying packaging details (e.g., drum linings, bulk‑bag moisture content) and confirming lead times - typically 2‑4 weeks for pigments and 1‑3 weeks for magnet sections - will reduce supply‑chain risk.

What types of magnetic materials are listed in the supplier’s catalogue?

The catalogue mentions magnetic materials without further detail; typical Chinese exporters provide ferrite, NdFeB and samarium‑cobalt alloys, each with standard grades such as ferrite Hc 800‑1200 kA/m or NdFeB BHmax 30‑45 MGOe.

What dimensions are common for the segment magnets offered?

Segment magnets are usually supplied in lengths from 10 mm to 200 mm and thicknesses of 2‑10 mm, with dimensional tolerances of ±0.1 mm as per ISO 9001‑based specifications.

What purity level can a buyer expect for the iron‑oxide red pigment?

Iron‑oxide red pigments from industrial suppliers typically have a Fe₂O₃ purity of 95‑99 % and a particle size range of 5‑10 µm; buyers should request a certificate of analysis to confirm these figures.

How is mill scale generally packaged for export?

Mill scale is commonly packed in 1‑tonne bulk polypropylene bags or in 20‑ft containers with moisture‑control liners to prevent oxidation during transit.

Which certifications are usually required for pigments and magnetic products from China?

Buyers normally request ISO 9001 quality system certification, REACH registration for pigments, and an MSDS for all chemical‑based items; magnetic products may also be checked against IEC 60404 safety standards.

What documentation should a buyer request before placing an order?

Typical pre‑order documentation includes a commercial invoice, packing list, certificate of origin, product data sheet, COA for pigments, and, where relevant, test reports such as ASTM B443 for magnets.

What are typical lead times and minimum order quantities for these products?

Lead times are generally 2‑4 weeks for pigment batches and 1‑3 weeks for segment magnets; minimum order quantities often start at 500 kg for pigments and 100 pieces for magnet sections, though exact figures depend on the supplier’s production schedule.

Which global regions most frequently import the listed product categories?

The main import markets for Chinese industrial supplies include the European Union for pigments and iron‑oxide red, the United States and Canada for magnetic components, and Southeast Asian countries for mill scale used in steel recycling.
