Custom high-end bag hardware OEM & ODM one-stop solution provider

Is your bag hardware factory ISO 9001 certified?

2026-10-15

ISO 9001 Quality Management Certification

Yes. Carosung's factory has obtained ISO 9001 certification. Our quality management approach covers key manufacturing activities, from incoming material inspection and production monitoring to final inspection and packaging.

Standard operating procedures help maintain consistency across production stages, while inspection records and corrective actions support ongoing quality improvement.

Product Testing and Regulatory Requirements

For customers selling into markets with specific chemical and product safety requirements, we can discuss suitable materials, surface-finishing options, and testing arrangements according to the product specifications and applicable regulations.

Relevant requirements may include:

REACH: European Union requirements concerning chemicals, including applicable restrictions and Substances of Very High Concern (SVHC).

RoHS: Restrictions on certain hazardous substances in products within the directive's scope.

California Proposition 65: Requirements relating to exposures to listed chemicals, where applicable.

Carosung has previously arranged testing for other customers against relevant requirements and obtained passing reports for those projects. These reports apply to the products and test conditions covered by the respective reports; they should not be interpreted as blanket certification of every Carosung product.

Testing can be arranged for a specific product or project when required. The applicable test scope and documentation should be confirmed according to the material, finish, destination market, and customer's compliance requirements.

Material Documentation

Material certificates and supporting documentation may be available depending on the material supplier, grade, and purchase requirements. Specific documentation should be confirmed before order placement.

What makes Carosung different from other bag hardware suppliers?

Flexible Customization and Manufacturing Support

Carosung supports brands at different stages of product development, from selecting existing hardware to developing fully customized components. Our services can include design evaluation, mold development, material selection, surface finishing, logo application, quality inspection, and packaging.

For selected stock products, customization may involve surface finishing and laser-engraved logos, offering a practical option for customers who need shorter lead times. Fully customized projects receive a more comprehensive development process based on their structural complexity and production requirements.

Surface Finishing Options

We offer PVD coating and traditional electroplating options, together with other finishes where applicable. The appropriate process depends on the base material, product structure, desired appearance, wear requirements, corrosion resistance, production quantity, and budget.

PVD coating can be suitable for applications requiring a durable decorative surface, while traditional electroplating offers a broad range of metallic colors and finishes. Both processes require appropriate surface preparation and process control.

Precision and Quality Control

Our manufacturing capabilities include CNC machining, metal stamping, die-casting, and manual or automated polishing. Dimensional tolerances are determined according to the product design, manufacturing process, and functional requirements.

We also evaluate surface quality before finishing to identify visible defects that may affect the final appearance.

Brand Protection and Packaging

We can support confidential product development, customized logo application, and private-label packaging. Where required, confidentiality agreements can be arranged to help protect customer designs and project information.

Our goal is to provide coordinated manufacturing support, practical technical advice, and consistent quality management throughout the product development process.
