Glass Factory Sample Ordering Process: Guide to Sample Shipping Costs, Lead Times, and Mold Fees
Ordering glassware from China doesn't have to be complicated. This guide provides real-world costs, timeline expectations, and mold fee structures so you can plan your glass sourcing with confidence.
Published on XUZHOU TROY | News & Insights
Ordering glassware from Chinese factories can feel like navigating a maze—especially when it comes to samples. What are the real costs? How long will it take? Are mold fees refundable? For international buyers, these questions often remain frustratingly opaque.
At XUZHOU TROY, we believe transparency builds trust. This guide provides a clear, straightforward breakdown of the sample ordering process, shipping costs, production lead times, and mold fee structures so you can plan your procurement with confidence.
Whether you’re a brand launching a new product line, a retailer sourcing custom jars, or a distributor testing quality before bulk orders, this guide covers everything you need to know about ordering glass samples from China.
Part 1: Understanding the Sample Request Process
Step 1: Initial Inquiry and Specification Confirmation
The process begins when you contact the factory with your requirements. To ensure accurate sampling, prepare the following information:
| Information Needed | Why It Matters |
|---|---|
| Product category | Bottle, jar, vial, or other glassware type |
| Capacity/Volume | Determines glass weight and dimensions |
| Neck finish/Thread | Regular mouth (70mm), wide mouth (86mm), or custom threads |
| Material type | Soda-lime, borosilicate, or amber glass |
| Color requirements | Clear, amber, cobalt blue, custom tinting |
| Surface decoration | Embossed logo, debossed logo, silk-screen printing, frosting |
| Estimated order quantity | Affects mold investment recommendations |
Pro Tip: The more detailed your specifications, the faster and more accurate your sample will be. Providing reference images or existing product dimensions helps eliminate misunderstandings.
Step 2: Sample Production or Selection
Two paths exist for sample acquisition:
Option A – Stock Sample (No Mold Fee) :
- If your required design matches an existing product, the factory can send stock samples
- Typically available immediately or within 3-7 days
- No mold fee required
- Recommended for initial quality assessment or when using standard designs
Option B – Custom Sample (Mold Required) :
- Required when your design differs from existing tooling
- Custom molds must be manufactured before sample production
- Cost structure: One-time mold fee (typically owner retained) + sample production cost
- Recommended for custom branding, unique shapes, or proprietary designs
Step 3: Sample Approval and Bulk Production
Once samples are produced and shipped, you’ll typically receive:
- Physical samples for quality inspection
- Dimensional measurement reports
- Photos and video of production process
- Material certifications (upon request)
After sample approval, you can proceed to place bulk orders. If changes are needed, we work with you to revise the sample before mass production begins.
Part 2: Mold Fee Structure – What to Expect
When Are Mold Fees Required?
Mold fees apply when:
- Your design requires new or custom molds not already in the factory’s inventory
- You request proprietary tooling for your exclusive use
- You require specific modifications to existing designs (e.g., custom neck finish, unique embossing)
Standard Mold Fee Ranges
| Glassware Type | Tooling Complexity | Typical Mold Fee Range (USD) |
|---|---|---|
| Simple bottle (standard shape) | Low | $1,000 – $1,500 |
| Moderate bottle (custom shape) | Medium | $1,500 – $3,000 |
| Complex jar (multi-part mold) | High | $3,000 – $5,000+ |
| Special neck finish (non-standard) | High | $2,000 – $4,000+ |
| Embossing/debossing inserts (logo) | Medium | $500 – $1,500 additional |
Note: Prices vary by factory and region. This guide is based on market average for mid-range suppliers in the Yangtze Delta region.
Mold Ownership and Retention
Standard Practice : Mold fees are typically a one-time investment paid by the buyer. Key terms to clarify:
- Ownership: The buyer retains full ownership rights (keep receipts/invoices as proof)
- Exclusivity: When you pay for the mold, the factory should not use it for other clients without your permission
- Storage: Factories usually store molds for 3-5 years; longer storage may incur fees
- Transfers: If you need the mold shipped to another factory, it’s possible at your shipping expense
Mold Fee Refund Policies
| Scenario | Refund Status |
|---|---|
| Sample fails to meet specifications | Typically full refund or remake at factory expense |
| You change your mind after mold completion | Usually non-refundable (mold is already manufactured) |
| Bulk order placed (minimum quantity met) | Many factories deduct mold fees from bulk order cost (depends on order size) |
| You cancel before mold production starts | Usually full refund (check terms) |
| Mold defect due to factory error | Full refund or replacement at factory expense |
Critical Question to Ask: “Is the mold fee amortized into bulk order pricing if we place a sufficiently large order?”
Hidden Costs to Anticipate
- Modification fees: Changes after mold completion can be costly (typically $300-800 per modification)
- Maintenance fees: Molds require periodic maintenance in high-volume production (often included in unit pricing, but confirm)
- Replacement charges: If mold is lost or damaged, replacement costs may apply (usually at fault party’s expense)
Part 3: Sample Lead Times – How Long Will It Take?
Timing is critical for product launches. Here’s a realistic timeline breakdown:
Stock Samples (No Customization)
| Step | Time Required |
|---|---|
| Inquiry response | 1-2 business days |
| Sample availability check | 1 business day |
| Logistics preparation | 1-3 business days |
| Total: Sample-ready | 2-5 business days |
| Transit time (shipping) | 3-7 days (express) or 10-15 days (standard) |
Custom Samples (New Mold Required)
| Step | Time Required |
|---|---|
| Design confirmation | 2-5 business days |
| Mold design & engineering | 5-10 business days |
| Mold manufacturing | 15-30 business days |
| Trial sampling (first run) | 3-5 business days |
| Sample inspection & adjustment | 2-5 business days |
| Total: Sample-ready | 25-50 business days |
Note: Complex designs or multi-cavity molds may extend timelines to 40-60 business days.
Factors That Affect Lead Times
| Factor | Impact |
|---|---|
| Mold complexity | More complex molds require longer engineering time |
| Factory workload | Peak seasons (before Chinese New Year, September-October) extend timelines |
| Design changes | Each change adds 3-10 days |
| Material availability | Colored glass or borosilicate may have longer lead times |
| Quality testing requirements | Extensive testing (food safety certifications) adds 5-10 days |
Peak Season Planning
Chinese New Year: Factories typically close for 1-3 weeks (late January to mid-February). Plan sample requests at least 6-8 weeks before this period.
Mid-Year Rush: September-October sees high demand due to Western holiday ordering. Lead times may extend by 1-2 weeks.
Part 4: Sample Shipping Costs – A Transparent Breakdown
International shipping costs depend on weight, dimensions, destination, and speed. Here’s a realistic estimate:
Shipping Cost Ranges
| Destination | Sample Weight | Express Shipping (3-7 days) | Standard Shipping (10-15 days) |
|---|---|---|---|
| North America | Under 2 kg | $35 – $55 | $20 – $35 |
| North America | 5-10 kg | $70 – $120 | $45 – $70 |
| Europe | Under 2 kg | $40 – $60 | $25 – $40 |
| Europe | 5-10 kg | $80 – $130 | $50 – $80 |
| Asia-Pacific | Under 2 kg | $25 – $40 | $15 – $25 |
| Asia-Pacific | 5-10 kg | $50 – $80 | $30 – $50 |
Based on 2026 average courier rates (DHL, FedEx, UPS, EMS). Prices subject to fuel surcharges.
How Shipping Costs Are Calculated
Two factors determine shipping cost:
- Actual weight: Physical weight of the package
- Volumetric weight: L x W x H (cm) ÷ 5000 (for express couriers)
Example: A 10 cm × 10 cm × 10 cm box:
- Actual weight: 1 kg
- Volumetric weight: 1000 ÷ 5000 = 0.2 kg
- Charged weight: Higher of the two = 1 kg
Pro Tip: For lightweight but bulky samples (like large jars), volumetric weight may exceed actual weight. Pack efficiently to minimize dimensional charges.
Who Pays for Shipping?
Standard Practice:
- Sample cost: Buyer pays (often non-refundable, unless applied to bulk order)
- Shipping cost: Buyer pays (factory can arrange shipping at cost)
- Customs duties: Buyer’s responsibility (typically samples under $50 value are duty-free, but verify your country’s regulations)
Negotiable Items
- Many factories offer free shipping for samples if you place a bulk order within a specified period
- Some factories will deduct sample costs from the first bulk order if you meet minimum quantities
- Express shipping is often faster and more trackable, but standard shipping may be acceptable for non-urgent samples
Part 5: What You’re Actually Paying For
Understanding the costs ensures no surprises. Here’s the breakdown:
Sample Cost Components
| Cost Element | Description | Typical Range |

Part 6: Top Tips for Smooth Sample Ordering
1. Prepare a Clear Sample Brief
Provide these essentials:
- Product sketches, photos, or CAD files with dimensions
- Target neck finish specifications (regular/wide mouth)
- Wall thickness requirements
- Glass type and color
- Volume/capacity requirement
2. Communicate About Mold Investment
- Ask: “Is this mold standard or custom for our design?”
- Ask: “What’s the expected mold lifespan (typical shot count)?”
- Clarify: “If mold transfer is needed later, what’s the process and cost?”
- Get it in writing: Ensure mold ownership terms are included in quotations
3. Plan Ahead for Seasonal Delays
- Submit sample requests at least 3 months before required delivery
- Allow extra time during Chinese New Year (late Jan – mid-Feb)
- Account for your own internal approval processes (discuss with your team)
4. Factor in Testing and Certification
- If you need food-grade compliance, budget $200-500 for testing
- Request material certificates from the factory (usually provided if requested)
- Allow 5-10 days for third-party certification if required by your market
5. Build a Relationship with Your Supplier
The best sample processes come from strong communication:
