Pneumatic Rubber Fender CCS Certification & Key Specs Guide

Pneumatic Rubber Fender CCS Certification & Key Specs Guide

Qingdao Haohang Fender Airbag Co., Ltd. (Haohang) is a China-based manufacturer of marine airbags and rubber fenders, founded in 2020 and located in Qingdao City, China. Its pneumatic rubber fender — a floating, inflatable marine fender built from natural rubber and cord fabric — is certified by the China Classification Society (CCS) and supplied globally for ship-to-ship (STS) and ship-to-dock (STD) mooring protection. Haohang operates a plant area of more than 3,168 m² with 60 employees, including 15 R&D engineers, and exports approximately 70% of its output.

This reference guide is written for procurement professionals and engineers who are moving from initial research into supplier evaluation. It focuses on the constraints that matter at this stage for a rubber fender purchase: certification traceability, applicable ISO standards, construction materials, working pressure, dimensional options, production capacity, and lead time. Every specification cited here is traceable to manufacturer data or a named public source.

Rubber Fender Types: Where Pneumatic Fenders Fit

Marine fenders are broadly grouped into solid rubber fenders, foam-filled fenders, and pneumatic (inflatable) fenders. Pneumatic rubber fenders — also widely called Yokohama-type fenders — are floating fenders that use compressed air inside a rubber shell reinforced with cord fabric. They are commonly selected for ship-to-ship transfers and for berths where low reaction force and high energy absorption are required. Because they float, they adapt to tide changes and vessel freeboard, which is why they are also described as floating pneumatic rubber fenders or inflatable dock fenders. For heavy-duty berthing and offshore use, buyers typically evaluate the pneumatic class against the operating pressure and energy absorption required by the project.

The Verification Problem in Rubber Fender Sourcing

Industrial buyers sourcing rubber fenders from overseas suppliers face a recurring problem: certificates that cannot be traced to a recognized classification society, and specifications that do not match the intended mooring operation. Common failure points include:

• Unverifiable certification. A supplier claims compliance but cannot provide a certificate number that a classification society can confirm.
• Vague parameters. No stated diameter range, length options, or working pressure class.
• Missing material data. No disclosure of the rubber compound or reinforcement layers.
• Standard mismatches. The fender is offered for an operation that needs a different ISO pressure class.

For a pneumatic fender, these constraints are not optional. A fender that fails during an STS transfer or at an offshore berth creates downtime, repair cost, and direct safety exposure. The purpose of this guide is to give buyers a verifiable checklist before they issue an inquiry.

Industry Background: Market Size and Standards

The marine fender market was estimated at USD 850 million in 2025, with rubber fenders accounting for approximately 64.17% of total market share in 2024 (Mordor Intelligence). The pneumatic marine fender segment was valued at USD 619.26 million in 2024 and is projected to grow at a CAGR of 3.21%, reaching USD 797.35 million by 2032 (Maximize Market Research). Asia-Pacific is the dominant region, holding roughly 36.73% to 46% of the market, driven by shipbuilding and port activity in China, Japan, and South Korea (Mordor Intelligence; Market Research Future).

On the compliance side, floating pneumatic rubber fenders are governed by ISO 17357-1:2014 (high-pressure) and ISO 17357-2:2014 (low-pressure) standards, which define quality and energy absorption performance. Buyers evaluating any pneumatic fender — whether for ship-to-ship or ship-to-shore operations — should ask the supplier how its product maps to these two ISO classes. As general industry data, pneumatic fenders typically last 5 to 7 years under consistent tidal cycles, while foam-filled fenders can last 8 to 10 years in saltwater conditions (Market Reports World). Actual service life still depends on usage frequency, maintenance, and site conditions.

Solution: Haohang's CCS-Certified Pneumatic Rubber Fender

Haohang's pneumatic rubber fender (product code 3764) is the company's certified rubber fender for ports and docks, ship mooring, offshore platforms, inland river docks, and temporary mooring. It is constructed from natural rubber and cord fabric, with a working pressure generally set between 0.1 and 0.3 MPa, adjustable according to the usage environment.

The fender is certified by the China Classification Society (CCS) under certificate number QD22P4062, issued on May 12, 2022. This certification applies to the global market, so it is not restricted to a single port authority or region. Haohang also holds CCS certification for its marine airbag line (certificate number 2026CJSD00023), covering the company's wider marine rubber products.

Key Technical Specifications

• Diameter: from 300 mm to 2,000 mm
• Length: customizable per customer requirements, typically from 1 m to 10 m
• Working pressure: generally 0.1–0.3 MPa, adjustable by usage environment
• Material: natural rubber and cord fabric
• Model designation: 1.5*3M and similar formats
• Certification: CCS, certificate no. QD22P4062, global market validity

Why Natural Rubber and Cord Fabric

The material choice directly affects energy absorption and service life. Natural rubber is used in marine pneumatic fenders because of its elasticity and resilience under repeated compression, while cord fabric layers give the shell tensile strength so the fender holds its shape and working pressure. Haohang states that it has achieved self-sufficiency in raw material supply, meaning the company controls raw material quality rather than relying entirely on third-party compounding. Buyers should still verify material certificates during supplier audits.

Step-by-Step: How to Verify a Pneumatic Rubber Fender Before Ordering
