About Hengshui Runli Rubber Plastic New Material Technology Co. Ltd. - Rubber Items Supplier in China

Based in China, Hengshui Runli Rubber Plastic New Material Technology Co. Ltd. currently lists eight distinct products in its catalogue. The listed items fall under the top categories of Rubber Items, Agriculture Nets, Blankets, and Conveyor Systems & Parts. Products include a Water Expansion Rubber Water Stop Belt, a Black Bidirectional Geogrid Plastic Net, and a GCL Natural Sodium Bentonite Waterproof Blanket which is recorded under HS code 2508.10. Additional rubber sealing solutions comprise a Steel Edge Rubber Water Stop, a Water Expansion Stop Ring, a Rubber Sealing Strip, a Rubber Water Stop Joint, and a Rubber Water Stop Belt. The bentonite blanket combines natural sodium bentonite with a geotextile encapsulation, while the other items are manufactured from rubber or plastic compounds.

Rubber water stop products are typically used in concrete joint construction to prevent water ingress and leakage. Geogrid plastic nets are employed in soil reinforcement and erosion control for agricultural and civil engineering projects. GCL blankets serve as impermeable layers in landfill liners and underground water barriers, leveraging the swelling properties of sodium bentonite. The catalogue does not provide individual HS codes for the rubber items, which are generally classified under HS Chapter 40 for rubber articles. These eight products represent the supplier’s current active offering and are positioned for export from China to markets that require engineered sealing and containment solutions.

Product Range and Specialties of Hengshui Runli Rubber Plastic New Material Technology Co. Ltd.

The catalogue features water stop belts and joints made from vulcanized rubber, a bidirectional geogrid net of high‑density polyethylene, and a geosynthetic clay liner (GCL) that incorporates natural sodium bentonite. In the industry, rubber water stop belts are often specified with a durometer of 60 - 70 Shore A and tensile strength exceeding 10 MPa to withstand concrete pressure. Geogrid nets used for soil reinforcement are commonly produced with tensile strengths of 200 - 500 kN m‑1 and aperture sizes ranging from 10 mm to 30 mm. Standard GCL products contain at least 80 % bentonite by weight, achieve a water permeability of less than 1 × 10⁻⁸ cm s⁻¹, and are supplied in rolls of 1 m width and lengths up to 500 m. Typical packaging for rubber water stop components includes wooden crates or bulk pallets, while GCL and geogrid are wound on paper or plastic cores for container loading.

Steel‑edge water stops integrate a steel reinforcement strip within the rubber profile to improve edge stability during installation. Such composite seals are frequently tested according to ASTM D4485 for water stop performance and ISO 1348 for dimensional tolerances. Buyers often request product data sheets that list dimensions, hardness, and chemical resistance to oils and alkalis.

Trade and Export Information - Hengshui Runli Rubber Plastic New Material Technology Co. Ltd.

China is a major exporter of rubber sealing products and geosynthetic materials, supplying construction and infrastructure projects across Asia, the Middle East, Africa, and Eastern Europe. The GCL blanket listed under HS code 2508.10 falls within the mineral products chapter, which is subject to customs duties and may require a phytosanitary certificate when shipped to certain jurisdictions. Rubber water stop items are classified under HS Chapter 40 (rubber articles) and typically require compliance with ISO 9001 quality management and, where applicable, CE marking for the European market. Importing buyers usually request test reports such as ASTM D4485 water tightness, ISO 14001 environmental compliance, and tensile test certificates. Standard logistics involve loading the rolled geosynthetics and bundled rubber components into 20‑ft or 40‑ft containers, with common Incoterms being FOB Shanghai or CIF destination port.

Customs clearance for GCL may involve verification of bentonite content and moisture level below 5 % to meet specification standards. Shipping lines often require that rolls be secured on pallets with shrink‑wrap to prevent damage during transit.

Sourcing from Hengshui Runli Rubber Plastic New Material Technology Co. Ltd. - Buyer Guidance

When sourcing from this supplier, buyers should request detailed product data sheets that specify durometer, tensile strength, dimensions, and material composition for each rubber water stop item. For the GCL blanket, a laboratory analysis confirming sodium bentonite content, permeability rating, and moisture percentage should be obtained. Standard certifications to ask for include ISO 9001, ISO 14001, and any relevant ASTM test reports such as D4485 for water stop performance. Samples of the geogrid net and GCL can be requested on a small roll (e.g., 5 m) to verify aperture size, tensile behavior, and bentonite activation. Buyers should also confirm packaging details, container loading plans, and the applicable Incoterm before finalizing the order.

Verification of the HS code alignment and export documentation (commercial invoice, packing list, certificate of origin) helps avoid customs delays, especially for the HS 2508.10 GCL which may be subject to import restrictions in certain countries.
