FAQs About Wholesale Storage Boxes

We’ve gathered the most commonly asked questions for your convenience. However, if you have any further inquiries, please don’t hesitate to reach out to us.

What packaging options are available for storage boxes?2025-06-30T06:12:09+00:00

We offer several packaging solutions to protect and efficiently ship your storage boxes, including:

  • Bulk Packaging: Boxes stacked and wrapped on pallets for cost-effective shipping. This is the most commonly chose packaging method by our clients with the lowest cost.

  • Individual Packaging: Each box packed separately in protective film or cartons for retail or e-commerce sales. You can sell them directly without the trouble of repackaging.

  • Custom Packaging: Branded cartons, labels, inserts, or special protective materials tailored to your requirements.

  • Eco-Friendly Options: Sustainable packaging materials available upon request.

Please note that the latter three methods may incur some additional costs.

Different packaging specifications are usually listed on the product detail page. If you need other options or custom packaging, please contact us for assistance.

What is your payment term?2025-06-30T03:26:23+00:00

We offer flexible payment terms and several secure methods for your convenience.

Payment Methods:

  • Wire Transfer (T/T)

  • PayPal

  • Western Union

Payment Terms:

  • Mold payment: 50% deposit upfront, 40% upon T1 sample approval, and the remaining 10% after final approval.

  • Product payment: 30% deposit upfront, with the remaining 70% due before product shipment.

How long is the sample lead time?2025-06-30T04:34:30+00:00

The lead time for samples can vary depending on your specific project. Here’s a general idea:

  • Standard parts or existing molds:
    If your part matches something we already produce, samples usually take about 3 to 7 days, depending on stock and shipping times.

  • Custom molded or machined parts:
    For new designs that require custom molds or mechanical processing, it usually takes 2 to 5 weeks to produce samples. This period includes the time for mold fabrication, preparatory work, and making minor adjustments according to your requirements.

  • 3D-printed prototypes:
    If you need to obtain the prototype product quickly, we also offer 3D printing services in metal or plastic materials. These samples can usually be completed within 3 to 5 days, depending on factors such as size, material, and surface treatment requirements.

  • Special finishes or testing:
    Surface treatments like anodizing, black oxidize, painting, etc.(click here to see our options), or specific functional tests might add a bit more time.

Once we know your part details, we’ll confirm the timeline and keep you posted throughout the process. Feel free to share your drawings or ideas so we can give you a more precise estimate!

Can I get samples for testing?2025-06-30T04:35:35+00:00

Yes, absolutely. At KingStar, we understand how important it is to check the quality and fit of your parts before moving into mass production.

In most cases, we can provide samples in small quantities — usually between 1 and 10 pieces (for 3D printing, CNC machining), or 10 to 100 pieces (for injection molding) depending on your part’s size, complexity, and production method.

We offer several options for making samples:

  • 3D Printing (Metal or Plastic): Great for fast prototypes or design validation, usually ready in just a few days. We usually provide 1-3 pcs as samples.

  • Trial Runs from Injection Molding: For plastic parts requiring high accuracy or specific materials, we can run small batches (usually 10-100 pcs) using soft or production tooling.

  • CNC Machining: Ideal for metal or plastic parts needing precise tolerances or certain material properties before committing to tooling. For machining, we usually provide 1-5 pcs as samples.

However, this is not fixed. If you need more samples than we usually provide, we are open to negotiate, and if your project requires special finishes, surface treatments, or functional testing, we’re happy to include those in the sampling process as well.

Let us know your part details, and we’ll advise the best way to produce your samples quickly and cost-effectively.

Can KingStar help me turn an idea into a product?2025-06-30T02:36:55+00:00

Before I provide my design/drawing/sketch, are you willing to sign a NNN or NDA to protect my intellectual property?2025-06-30T02:29:16+00:00

Absolutely — protecting our customers’ intellectual property is one of our highest priorities. We fully understand the sensitivity and value of proprietary designs, drawings, or any confidential information you share with us.

We are willing and ready to sign either a standard NDA (Non-Disclosure Agreement) or a more comprehensive NNN Agreement (Non-Disclosure, Non-Use, Non-Circumvention) upon request.

Once an NDA or NNN agreement is in place, we guarantee:

  • Strict confidentiality: All technical data, drawings, specifications, and communications remain strictly confidential and are used only for your project.

  • Non-use commitment: We will not use your designs or proprietary information for any purpose other than producing your parts or providing requested services.

  • Non-circumvention: We will not share your contacts, suppliers, or project details with third parties or attempt to bypass you in any commercial dealings.

  • Secure data handling: We maintain secure systems and protocols to store and manage confidential documents safely.

Our team works with clients from industries like automotive, aerospace, medical devices, consumer products, and many others — all of which require the highest levels of confidentiality and trust.

Please feel free to discuss any specific confidentiality needs with us, and we’ll make sure proper agreements are in place before reviewing your designs.

How are your storage boxes tested for durability?2025-06-30T05:23:41+00:00

At KingStar Mold, we ensure all storage boxes undergo rigorous durability testing to meet both internal quality benchmarks and international standards. Common tests include:

  • Drop Testing: Simulates impacts from falls or handling to assess resistance to cracks or breaks, following standards like ASTM D5276.

  • Load Testing: Verifies stackability and weight-bearing capacity under sustained pressure, complying with ISO 8611.

  • Environmental Testing: Evaluates performance under temperature, humidity, and chemical exposure to ensure boxes maintain integrity in different conditions, based on ISO 16750 or similar protocols.

  • Material Hardness and Impact Resistance: Using tests such as Rockwell or Izod impact tests to confirm material strength and toughness.

These tests guarantee that our storage boxes perform reliably in real-world applications, providing long-term durability for industrial, commercial, and home uses. You can also check for details on our quality management page.

What is the cost of your storage boxes?2025-06-30T05:34:40+00:00

For ready-made storage boxes, prices typically range from a few dollars per piece for simple designs using common materials, up to several tens of dollars for complex designs with premium materials. Large volume orders usually benefit from lower per-unit prices thanks to economies of scale.

For custom storage boxes, the cost depends on multiple factors, including:

  • Material costs

  • Tooling costs (mold material, machining complexity, lifespan)

  • Labor and overhead

  • Post-processing (surface finish, printing, assembly)

  • Order quantity

The unit cost can be roughly calculated by:

Unit Cost = Total Cost (tooling + material + labor + overhead + post-processing) Ă· Total Production Quantity

This means that as production volume increases, the cost per unit decreases.

What is the lead time for custom storage boxes?2025-06-30T04:49:25+00:00

The lead time for custom storage boxes depends on your specific design, order quantity, and any special finishing requirements. Generally, you can expect:

  • Standard designs with minor customizations (like color, logo printing): about 2–4 weeks after order confirmation.

  • Fully custom molds or unique designs: typically 4–6 weeks for tooling and sampling, followed by 2–3 weeks for mass production once samples are approved.

Are your storage boxes stackable?2025-06-30T04:48:18+00:00

It depends on whether you’re buying our ready-made products or looking for a custom design:

  • For ready-made storage boxes:
    Many of our standard boxes are indeed stackable. Usually, you can tell right away because “stackable” is often included in the product title.

If you’re browsing our catalog, look for labels like stackable, nestable, or interlocking lids.

  • For custom storage boxes:
    Yes — we can absolutely help you design custom stackable storage boxes to fit your specific needs. Common stackable features we can incorporate include:

    • Interlocking lids to keep stacks stable

    • Reinforced corners or ribbing for extra strength

    • Anti-slip bases to prevent shifting

    • Nesting designs to save space when empty

    • Specific load-bearing capacities for stacked storage

If stackability is important for your application, just let us know your requirements, and we’ll help you choose the right solution or design a custom box that stacks safely and efficiently.
