Are you concerned about sourcing glassware from China due to reports of product recalls, potential toxins, and fake certifications? As a glassware manufacturer with over 15 years of global export experience, we understand your concerns. This uncertainty often stems from an information gap—not knowing the right questions to ask.
Yes, glassware from China is safe—but only if you choose a supplier who can proactively provide verifiable certifications, transparent material data, and a strict quality control process. In this article, we will show you, from a factory’s perspective, all the key elements a reliable partner should possess.
We have seen countless importers succeed, and they all have one thing in common: they partner with transparent, professional factories like us. This guide will show you how we ensure every glass food storage container, mug, and piece of cookware is absolutely safe, compliant, and reliable.
📌 What safety certifications should my supplier provide?
Many importers mistakenly believe “glass is just glass,” but as manufacturers, we know the difference. Poor-quality glass can contain high levels of lead or leach chemicals when heated. If your supplier cannot provide the correct certifications, your business faces enormous risks, including lawsuits, product recalls, and lost retail contracts.
✅ A professional supplier must be able to proactively provide you with FDA, LFGB, and DGCCRF certifications. At our factory, these are not “optional extras”; they are the foundation of our quality promise for every shipment.
We believe providing these certifications is the duty of any responsible factory. They are your passport to market access and the first line of defense in protecting our shared brand reputation. Below, we’ll break down what these certifications mean.
✅ The Core Safety Certifications We Provide
To ensure your products are compliant, we strictly adhere to the standards of major global markets. 食品医薬品局 1{#ref-1} is fundamental for our US exports, while LFGB 2{#ref-2} そして DGCCRF 3{#ref-3} represent stricter European standards. We are proud to meet all of these demanding requirements.
| 認証 | Region | What It Confirms | Applies To |
|---|---|---|---|
| 食品医薬品局 | アメリカ | Safe for food contact, no heavy metal or toxic substance migration | All our food-contact products |
| LFGB | Germany/EU | Stricter than FDA; checks color migration, odor, lead/cadmium levels | Our cookware, mugs, containers |
| DGCCRF | フランス | Ensures glass is safe under microwave, heat, and cold conditions | Our bakeware, jars, food storage |
🔍 How You Should Verify Our Certifications
We encourage all clients to verify our certification reports because transparency is the beginning of trust. A good factory will gladly assist you with verification and proactively provide all necessary information.
- We will provide PDF lab test reports issued within the last 12 months. We conduct tests regularly to ensure ongoing compliance.
- We ensure the product photos and batch numbers on the report match your order exactly.
- Our tests are conducted by internationally recognized agencies (like SGS, TÜV, BV) 4{#ref-4}, and the reports include a QR code or tracking number for your verification.
Remember: If a supplier only gives you a verbal promise of being “FDA approved” but cannot produce a traceable, original report, be very cautious.
📌 How do we ensure glassware is truly food-grade and free of lead, nickel, and cadmium?
“Lead-free” is a core concern for global consumers, and controlling for other heavy metals like nickel and cadmium is equally important. As a manufacturer, we know that simply claiming “non-toxic” is not enough. We must prove the absolute safety of our products with data, especially for cookware and drinkware that will be heated.
✅ To guarantee our products are truly food-grade and non-toxic, we conduct rigorous heavy metal testing (including for lead, nickel, and cadmium) on all raw materials and finished goods, ensuring they meet the world’s strictest standards like California’s Prop 65 5{#ref-5} and the EU’s REACH 6{#ref-6}.
We believe that presenting these detailed test reports to our clients is our unconditional responsibility. It’s a commitment not only to you but also to every end-user.
🔍 How to Read the Heavy Metal Reports We Provide
In the passing reports we provide, you will see that the test results for key heavy metals are far below the regulatory limits. We will clearly mark the key data for you and include the final “PASS” conclusion.
| Test Item | Our Promised Acceptable Result | 備考 |
|---|---|---|
| Lead (Pb) Content | < 0.01 mg/L | Near or below the detection limit, representing extreme safety |
| Cadmium (Cd) Content | < 0.005 mg/L | Meets and exceeds the mandatory LFGB/DGCCRF requirements |
| Prop 65 Compliance | PASS | Ensures our glass contains no known carcinogenic or teratogenic toxins |
👀 How to Conduct a Quick On-site Test
We welcome clients to conduct any form of spot check on our mass production goods. Our advice is that it’s impossible for an individual to tell by eye, and you should try to avoid unusually low-priced products. The most accurate proof is always the lab report we provide or a third-party test report.
📌 What quality control process should my supplier follow to ensure safety?
Certifications are just the entry ticket. We know that consistent, stable high quality comes from a comprehensive quality control (QC) process 7{#ref-7}。. This is the core of how we’ve earned the trust of our global clients.
✅ At our factory, we implement a strict, multi-stage QC process. From raw material intake to finished product shipment, quality is built into every single step. We firmly believe that quality is manufactured, not just inspected.
We are happy to show you our QC workflow and inspection reports, as they are a testament to our professionalism. A factory that cannot demonstrate its internal quality control processes cannot guarantee long-term, stable quality.
🏭 Our Quality Control Checklist: The Standard for a Top-Tier Partner
The following is the QC process we execute daily at our factory. We believe this is also the standard you should use to evaluate any potential supplier.
| QC Step | What We Check | When It’s Done |
|---|---|---|
| Raw Material Inspection (IQC) | Confirms high-borosilicate purity, eliminating heavy metals at the source | Before production begins |
| In-Process Inspection (IPQC) | Checks dimensions, clarity, and finish; rejects defects in real-time | During production |
| 落下テスト | Ensures structural durability for handling and shipping | Post-production batch check |
| Leak-Proof Test | Guarantees a 100% seal for containers with lids | Before packing |
| AQL Inspection | Conducts random sampling on mass orders to international standards | Before shipment |
Our Commitment: We insist on using high-quality 高ホウケイ酸ガラス 8{#ref-8}. Because it is stronger, safer, and more heat-resistant, it is the only choice for manufacturing first-class cooking pots, bakeware, and measuring cups.
📌 How do we protect your goods from breaking during shipment?
As your partner, our job isn’t finished when the product leaves the assembly line. We know that if your goods are damaged in transit, it results in a significant loss for you.
✅ To minimize the risk of breakage, we have developed a robust packaging and logistics strategy, validated by rigorous drop tests. Ensuring your cargo arrives safely is our responsibility.
We have handled the export of tens of thousands of glass bowls, jars, and cookware sets. Our extensive experience has taught us that an excellent packaging solution is key to controlling costs and protecting profits.
📦 The Packaging & Shipping Solutions We Provide
We offer layered, customizable packaging solutions—from the inner box to the master carton to the pallet—to withstand the rigors of international shipping.
| Protection Strategy | 説明 | Ideal For |
|---|---|---|
| Double-Wall Corrugated Boxes | Absorbs impact during transit; this is our standard configuration | All glass items |
| Individual Inner Boxes | Prevents items from making contact and rubbing, especially for retail | Mugs, measuring cups |
| EPS Foam or Molded Pulp Trays | Secures the product tightly in the box, providing optimal cushioning | Bakeware, food container sets |
| Shrink Wrap + Desiccant | Controls humidity to prevent mold or odors on accessories like bamboo lids | 竹蓋付きガラス瓶 |
| Carton Drop Test | Simulates real-world logistics impacts as a final validation before shipment | All export orders |
Our Extra Promise: We will customize and optimize the packaging solution based on your final shipping method—whether it’s LCL (Less than Container Load) 9{#ref-9}, FCL (Full Container Load), air, or sea freight. And our use of AQL Inspection 10{#ref-10} ensures final quality before your order ships.
