About Nanhao Rubber Industry Co., Ltd. - Rubber Products Supplier in China

Nanhao Rubber Industry Co., Ltd. is based in China; the supplier lists eleven active product types in its catalogue. The catalogue includes O‑ring & rubber seal, V‑belt, Conveyer belt, Rubber wheel & caster, Rubber hose, Air hose, Fuel hose, Seal strip, Bridge rubber bearing, Road and Rubber dam. Each entry falls under the broader rubber products HS chapter 40, which covers rubber and plastics articles. The supplier is classified as an imported tier with a harbor trust tier, indicating it operates through third‑party logistics for overseas buyers.

The product list shows a focus on sealing and conveyance solutions made from standard rubber compounds such as NBR, EPDM and natural rubber. Items such as bridge rubber bearings and rubber dams suggest applications in civil engineering and infrastructure projects, while the hose range targets automotive, industrial and pneumatic systems. No specific certifications are stated in the provided data, so buyers should verify compliance with relevant standards during procurement. The catalogue’s breadth across seals, belts and bearing components reflects a typical Chinese rubber manufacturer’s product portfolio.

Product Range and Specialties of Nanhao Rubber Industry Co., Ltd.

The catalogue covers eleven rubber‑based items. O‑rings and rubber seals are commonly produced in durometer ranges from Shore A 45 to 90, using NBR for oil resistance or EPDM for weather resistance. V‑belts are offered in standard A, B, C and D profiles, with fabric or steel reinforcement and tensile strengths of 150‑250 MPa. Conveyer belts typically use PVC or PU compounds with a tensile strength of 30‑80 MPa and thicknesses from 2 mm to 20 mm. Rubber wheels and casters often feature a polyurethane tread over a rubber core, sized from 50 mm to 300 mm in diameter. Hoses are supplied in standard diameters (10 mm‑200 mm) with reinforcement layers; fuel hoses frequently meet SAE 3 or 4 specifications, while air hoses conform to ISO 4422 pressure ratings up to 12 bar. Seal strips are cut to custom lengths and widths, bridge rubber bearings are fabricated in sizes up to 2 m × 2 m with shear modulus around 1.5 MPa, and rubber dams are molded for flood‑control or ponding applications.

Industry practice for these categories includes offering material data sheets, hardness (Shore A) values, temperature limits (‑40 °C to +120 °C for most NBR products), and compliance with standards such as ISO 9001 for quality management. Buyers typically request information on compound formulation, reinforcement type and dimensional tolerances before finalising orders.

Trade and Export Information - Nanhao Rubber Industry Co., Ltd.

China is a leading exporter of rubber products under HS chapter 40, with major shipments to Southeast Asia, Europe and North America. Automotive manufacturers in Germany, the United Kingdom and the United States frequently import O‑rings, hoses and V‑belts for assembly lines, while construction firms in the Middle East source bridge bearings and rubber dams for infrastructure projects. Typical import documentation includes a commercial invoice, packing list, certificate of origin and, where required, a material safety data sheet (MSDS). Common certifications requested by overseas buyers are ISO 9001, ISO 14001 and, for food‑contact hoses, FDA 21 CFR 184.1665 compliance. Logistics for these items usually involve 20‑ft or 40‑ft containers, with packed bundles of belts or hoses on pallets, and hazardous‑material labeling for fuel hoses meeting UN 1950 regulations.

Customs authorities in many importing countries may inspect rubber products for compliance with REACH (EU) or TSCA (USA) chemical restrictions. Exporters from China often use FOB or CIF Incoterms, with freight forwarding firms arranging container loading and marine transport. Seasonal demand peaks for conveyor belts and rubber hoses align with automotive production cycles in Q2‑Q3, influencing lead‑time negotiations.

Sourcing from Nanhao Rubber Industry Co., Ltd. - Buyer Guidance

Buyers should request a product data sheet that lists the rubber compound, hardness (Shore A), temperature range, reinforcement type and dimensional tolerances for each item. For hoses, confirm the applicable standard (e.g., SAE 3, ISO 4422) and request pressure‑test reports or burst‑strength certificates. Seal strips and O‑rings typically require dimensional drawings and a hardness verification report before bulk orders. When sourcing bridge rubber bearings or rubber dams, ask for load‑capacity calculations, shear‑modulus values and any applicable civil‑engineering certification. Samples of the exact compound are advisable to verify compatibility with the buyer’s equipment, and third‑party laboratory test reports (e.g., ASTM D2000 for hose material) should be obtained prior to shipment.

Verification of ISO 9001 or ISO 14001 certification, if claimed, can be done through the certifying body’s online directory. Buyers should also ensure that packaging meets ISO 1161 (for hose reels) or ISO 1183 (for bulk rubber) standards, and that containers are sealed with tamper‑evident tape. Confirm lead times, minimum order quantities (often expressed in metric tonnes or pallet counts) and the Incoterm to be used before finalising the purchase agreement.

What types of rubber compounds does Nanhao offer for O‑rings and seals?

The catalogue does not specify compounds, but typical Chinese rubber suppliers provide NBR for oil resistance, EPDM for weather resistance and silicone for high‑temperature applications. Buyers should request the exact compound and hardness (Shore A) data.

Are V‑belts supplied in standard A, B, C, D profiles?

While the catalogue lists V‑belts generically, industry practice is to offer the four standard profiles with fabric or steel reinforcement. Ask for the belt length, width and tensile strength ratings.

What standards apply to the fuel hoses?

Fuel hoses are normally manufactured to SAE 3 or SAE 4 specifications, which define minimum burst pressure (≈ 500 psi) and material compatibility with gasoline or diesel. Request the SAE standard reference and a pressure‑test report.

Can I obtain material safety data sheets for the rubber dam products?

MSDS are standard for rubber products used in civil applications. Request the sheet to verify compliance with REACH or TSCA chemical limits.

What packaging is used for bulk rubber hoses?

Bulk hoses are typically coiled and packed on wooden pallets, wrapped in stretch film, and loaded in 20‑ft or 40‑ft containers. Verify that the packaging meets ISO 1183 for bulk rubber handling.

Which HS code family covers the listed products?

All listed items fall under HS Chapter 40 (Rubber and articles thereof), with sub‑headings such as 4015 for O‑rings, 4009 for conveyor belts, and 4016 for hoses.

What certifications should I request before purchasing?

Commonly required certifications include ISO 9001 for quality management, ISO 14001 for environmental management, and product‑specific standards such as SAE for fuel hoses or ASTM D2000 for hose material. Verify these certificates with the issuing body.

What are typical lead times for these rubber products?

Lead times vary by product size and order volume; standard rubber hose orders from China often require 30‑45 days, while custom‑molded bridge bearings may need 60‑90 days. Confirm the supplier’s production schedule for each item.
