confirmed specifications, approved samples, inspection criteria, and agreed commercial terms.

Quality Concerns and Claims

If a customer identifies a potential quality issue, we recommend submitting clear photographs or videos, the affected quantity, the relevant order number, and available batch or packaging information.

Our team can review the information against the agreed specifications, approved samples, and available production or inspection records. Additional samples or testing may be requested when necessary to determine the cause.

Resolution and Corrective Actions

If a quality issue attributable to manufacturing is confirmed, the appropriate corrective action will be discussed according to the circumstances and the applicable agreement.

Possible solutions may include replacement, rework, a credit, or another mutually agreed arrangement. Responsibility, scope, and associated costs are determined based on the confirmed findings and contractual terms.

Response and Communication

Customers can contact their sales representative to report quality concerns and provide supporting evidence. Our team will review the information and communicate the next steps.

Response targets, claim submission deadlines, and resolution arrangements should be confirmed in the relevant order terms or after-sales policy.

Our objective is to address confirmed quality concerns professionally, support customers after delivery, and use the findings to improve future production.

Metal bag hardware requires suitable packaging to protect its surface finish and prevent damage during handling and transportation. Carosung selects packaging according to the product, finish, order quantity, and shipping requirements.

Individual and Inner Packaging

Depending on the product, packaging options may include:

• Individual OPP bags or other suitable protective packaging.
• Separators or compartments to reduce contact between metal components.
• Protective foam, trays, or cushioning materials.
• Customized printed bags or retail gift boxes.

For mirror-polished or delicate finishes, suitable separation between individual pieces helps reduce the risk of scratches caused by metal-on-metal contact.

Outer Cartons and Transportation Protection

Finished products are packed in suitable export cartons. Carton strength, internal cushioning, and packing arrangements are selected according to product weight, quantity, stacking requirements, and shipping conditions.

For fragile or sensitive components, additional protective materials may be used where necessary.

Moisture and Corrosion Protection

For products that may be vulnerable to moisture-related corrosion, suitable protective packaging can be considered based on the material, finish, transportation route, and storage conditions.

Additional measures may include moisture barriers, desiccants, or corrosion-inhibiting materials where appropriate. These measures can reduce certain risks but cannot eliminate all possible corrosion under every transportation or storage condition.

Shipping Options

Air freight, express courier, and sea freight can be considered according to the order quantity, destination, budget, and delivery schedule.

Packaging specifications and shipping arrangements can be confirmed before production is completed.

Once the order is confirmed, Carosung coordinates production planning, material preparation, manufacturing, quality inspection, packing, and shipment.

1. Order Confirmation and Production Planning

The order specifications, quantities, approved drawings, surface finishes, packaging requirements, and delivery schedule are reviewed before production begins.

Where applicable, production documents and material requirements are prepared to guide the manufacturing process.

2. Material Preparation and Inspection

Materials and components are sourced according to the confirmed specifications. Incoming inspection and supporting documentation are handled according to the material, supplier records, and project requirements.

3. Manufacturing and Surface Finishing

Depending on the product, manufacturing may involve die-casting, stamping, CNC machining, polishing, assembly, PVD coating, electroplating, or other finishing processes.

The specific sequence depends on the product structure and the selected manufacturing and finishing methods.

4. Quality Inspection

In-process checks are carried out at relevant manufacturing stages. Final inspection may cover dimensions, appearance, color, assembly, and functionality according to the agreed specifications.

Additional tests or third-party inspections can be arranged where required and agreed for the project.

5. Packing and Shipment

Finished products are packed according to the confirmed packaging requirements. Shipping documents, such as commercial invoices and packing lists, are prepared as applicable.

Shipment arrangements and tracking information are provided according to the agreed logistics service.

Customers can confirm the expected production milestones and communication arrangements with our team when placing the order.

Sample development time depends on the product design, manufacturing process, material, surface finish, and whether new tooling is required.

Stock Hardware with Custom Logos

For selected in-stock products requiring laser-engraved logos, samples can generally be prepared in 5–7 days, subject to stock availability and customization requirements.

Customized Products Using Existing Tooling

For customized products that can be manufactured using existing tooling, sample development generally takes around 20–25 days, depending on the product and finishing requirements.

Products Requiring New Molds

For products requiring new mold development, the sample development process generally takes around 30–35 days. This includes the relevant tooling, trial production, and sample finishing stages, subject to the project's complexity.

Complex mechanisms or special finishing requirements may require additional time.

Design Review and Prototype Evaluation

Technical drawings or 3D CAD models may be prepared during the initial development stage, depending on the information provided and the project's complexity.

Where useful, a preliminary prototype may be considered to assess dimensions or appearance before final metal tooling is produced. Prototype methods and timing are confirmed separately.

Sample Delivery

The times above refer to sample preparation and development, not international shipping. Courier transit time should be added when calculating the date the sample will arrive at the customer's location.

A project-specific schedule can be provided once the design, material, finish, and tooling requirements are confirmed.

Yes. Customers can develop and evaluate samples before deciding whether to proceed with mass production.

Stock Samples

For selected in-stock products, samples with laser-engraved logos can generally be prepared in 5–7 days, depending on stock availability, logo requirements, and the finishing process.

Customized Samples

For customized products, sample development time varies according to the material, structure, manufacturing method, surface finish, and whether new tooling is required.

Where a new mold is needed, mold development and trial production will affect the sample schedule.

Sample Evaluation

Samples allow customers to review dimensions, appearance, logo placement, color, assembly, and functionality before mass production.

Additional testing can be discussed when the product has specific mechanical, coating, or compliance requirements.

Sample and Tooling Costs

Sample charges and tooling costs depend on the project. Any credit or refund of these charges against a future bulk order must be confirmed in the quotation or commercial agreement.

Sample approval does not automatically require a bulk order unless otherwise agreed. Customers can use the sample evaluation stage to determine whether the product meets their requirements before making a production commitment.

Starting a project with Carosung involves a series of steps designed to clarify requirements, assess manufacturability, and confirm the product before mass production.

Step 1: Share Your Requirements

Customers can provide reference images, sketches, technical drawings, 3D CAD files, existing samples, or a description of the intended product.

Helpful information includes:

Product dimensions and functional requirements.

Preferred material and surface finish.

Logo application requirements.

Estimated order quantity.

Target budget and delivery schedule.

Packaging and destination market requirements, where applicable.

Step 2: Technical Review

Our team reviews the available information and assesses the design's manufacturing feasibility. Where necessary, we may request additional dimensions, clarify the intended function, or recommend design adjustments.

The time needed for this stage depends on the completeness of the information and the complexity of the project.

Step 3: Quotation and Sample Development

Once the requirements are sufficiently clear, we provide a quotation covering applicable tooling costs, sample charges, unit prices, estimated lead times, and other agreed requirements.

Samples are developed according to the product type and project scope. For new designs, tooling may be required before a finished metal sample can be produced.

Step 4: Sample Approval and Order Confirmation

Customers review the sample and confirm the required appearance, dimensions, function, and other agreed specifications.

Mass production proceeds after the relevant sample approval, order confirmation, and agreed payment arrangements.

Step 5: Production and Shipment

During production, quality inspections are conducted according to the agreed requirements. Finished products are packed and shipped using the selected logistics arrangements.

Shipping terms, such as FOB, CIF, or DDP, can be discussed according to the destination, order requirements, and agreed commercial conditions.
