10 Key Questions to Ask Your Glass Bottle Manufacturer Before Ordering

Choosing the right glass bottle manufacturer is one of the most critical decisions for brands in the spirits, beverage, cosmetics, and pharmaceutical industries. The right partner ensures product integrity, brand consistency, supply chain reliability, and market appeal.

Before you place an order, asking strategic questions can help you avoid costly mistakes, align expectations, and build a productive long-term partnership. Here are the 10 essential questions to ask any potential glass bottle supplier.

1. What types of glass do you specialize in, and which is best for my product?

Glass composition matters. Ask whether they work with soda-lime glass, borosilicate glass, or lead-free crystal glass. For premium spirits like whiskey or vodka, flint glass or crystal-white glass is often preferred for clarity and brilliance. Ensure the material is food-grade, non-reactive, and aligns with your brand's quality standards.

2. Do you offer custom design and mold development?

If you need a unique bottle shape, embossed logo, or custom color, verify the manufacturer's in-house design and mold-making capabilities. Key follow-ups:

• What is the cost and timeline for mold development?

• What are the MOQs for custom designs?

• Can you assist with 3D prototyping or sample revisions?

3. What is your minimum order quantity (MOQ)?

MOQs vary widely. Whether you're a craft distillery or an established brand, confirm the minimum order for both standard and custom bottles. Some suppliers offer lower MOQs for stock designs, which can be advantageous for startups.

4. What is your typical lead time from order to delivery?

Understanding the timeline is crucial for inventory and launch planning. Ask for a breakdown:

• Production time

• Quality inspection and packing

• Shipping and customs clearance (if importing)

• Possible seasonal delays

5. Can I get physical samples before full production?

Always request samples to assess quality firsthand. Evaluate the glass clarity, thickness, finish, and overall aesthetics. This step helps prevent mismatches between expectations and the final product.

6. What quality control systems do you have in place?

A reliable manufacturer follows strict QC protocols. Inquire about:

• In-process inspections and defect tracking

• Compliance with international standards (FDA, ISO, etc.)

• Willingness to share quality certifications or inspection reports

• Average defect rate and how they handle rejections

7. Do you provide turnkey packaging solutions?

Some manufacturers offer end-to-end services, including:

• Caps, closures, and corks

• Labeling and silk-screen printing

• Secondary packaging (boxes, cartons)
  This can simplify sourcing and ensure component compatibility.

8. What is included in your pricing?

Request a detailed quotation covering:

• Per-unit cost based on volume

• Mold/tooling charges (if applicable)

• Packaging and palletizing fees

• Shipping terms (FOB, CIF, etc.) and insurance

• Payment terms and discounts for repeat orders

9. How do you handle shipping and logistics?

If you're importing, logistics matter. Ask:

• Which shipping methods do you offer (sea, air, land)?

• Do you handle export documentation and customs?

• Can you provide door-to-door delivery service?

• What is your policy for shipping damage or loss?

10. Can you share references or case studies from similar clients?

A credible supplier should provide examples of past projects, especially within your industry. Ask for client testimonials, portfolio images, or case studies related to whiskey, vodka, cosmetics, or other relevant sectors.

Why These Questions Are Important

Asking these questions helps you evaluate not just the product, but the supplier’s expertise, reliability, and alignment with your brand vision. The right glass bottle manufacturer becomes an extension of your brand—delivering quality, consistency, and value from production to shelf.
