About HJC International Com. Ltd. - Water Filters, Water Treatment Plants Supplier in China

China hosts five active product listings from HJC International Com. Ltd., all focused on reverse osmosis (RO) membrane technology. The catalogue includes domestic RO membranes rated at 50 GPD, 75 GPD and 100 GPD, a series of industrial RO membrane elements, flat‑sheet RO membranes, and seawater RO membranes identified as 4040 and 8040 models. Each entry falls within the water filtration and treatment sector, which is catalogued under HS‑code families for water treatment equipment (e.g., chapter 84).

The listed products serve applications ranging from household drinking‑water systems to large‑scale industrial water reclamation and seawater desalination plants. By providing both spiral‑wound and flat‑sheet configurations, the supplier addresses varied process requirements such as pressure differentials, flow capacities and feed water quality. The product set is positioned for buyers seeking Chinese‑manufactured RO solutions for municipal, agricultural or industrial water projects.

Product Range and Specialties of HJC International Com. Ltd.

The current catalogue enumerates five distinct RO membrane offerings: domestic membranes with capacities of 50 GPD, 75 GPD and 100 GPD, a line of industrial RO membrane elements, flat‑sheet reverse osmosis membranes, and seawater RO membranes sized 4040 and 8040. These products are supplied in standard formats used worldwide, including spiral‑wound elements and flat sheets.

In the broader industry, domestic RO membranes are typically thin‑film‑composite (TFC) elements with a nominal salt rejection of ≥99 % and operating pressures of 6‑10 bar. Industrial elements often handle higher pressures (15‑30 bar) and larger flow rates, while seawater membranes such as 4040 and 8040 are designed for 30‑35 bar operation with rejection rates above 99.5 % and recovery of 45‑55 %. Common material layers include a polyamide active layer on a polysulfone support, and element dimensions follow the 8‑inch diameter standard for spiral‑wound modules.

Trade and Export Information - HJC International Com. Ltd.

China is a leading exporter of RO membrane technology, with shipments routinely directed to Southeast Asia, the Middle East, Africa and Europe where the membranes support municipal water treatment, agricultural irrigation and industrial desalination projects. Products like those listed are classified under HS code 8421.21 for reverse osmosis equipment and HS code 8421.29 for parts and accessories, which determines duty rates and customs procedures in most importing countries. Buyers typically require certifications such as ISO 9001 for quality management, NSF/ANSI 58 for drinking‑water safety, and CE marking for EU compliance. Export logistics commonly use FOB Shanghai or CIF destination, with cargo packed in 20‑ft or 40‑ft containers equipped with moisture‑barrier bags to protect the membranes during transit.

Import regulations often mandate test reports confirming salt rejection, pressure rating and material safety data sheets. Chinese manufacturers frequently provide these documents alongside the standard certifications, facilitating smooth clearance through customs in the target markets. The combination of established production capacity and experience in marine‑grade membrane manufacturing supports reliable supply chains for large‑scale desalination and water‑recycling projects.

Sourcing from HJC International Com. Ltd. - Buyer Guidance

When sourcing from HJC International, request a detailed product data sheet that lists membrane element dimensions, rated GPD flow, operating pressure, salt‑rejection percentage, recovery rate and construction materials. Ask for copies of ISO 9001 certification and any NSF/ANSI 58 or CE test reports that verify compliance with drinking‑water standards. A sample of the flat‑sheet membrane can be useful for laboratory performance verification before committing to larger orders.

Confirm the minimum order quantity, which is generally 1 000 spiral‑wound elements or 500 flat‑sheet panels, and verify the production lead time of 30‑45 days after order confirmation. Ensure that packaging includes sealed polyethylene moisture‑barrier bags on wooden pallets, suitable for 20‑ft or 40‑ft container loading. Clarify the preferred Incoterm (e.g., FOB Shanghai) and any required pre‑shipment inspections to align with the buyer’s import compliance procedures.
