Company Profile

Xuzhou Jianmei Glass Products Co., Ltd.

Xuzhou Jianmei Glass Products Co., Ltd. is a specialized borosilicate glass manufacturer with deep technical expertise in high-temperature glass forming, precision annealing, and automated quality control. Strategically located in Xuzhou, Jiangsu Province — a region with over 50 years of concentrated glass manufacturing heritage — our factory leverages local raw material supply chains, skilled workforce, and established logistics infrastructure to deliver high-quality glassware at competitive export prices.

Our manufacturing facility is a vertically integrated operation. Incoming borosilicate glass tubing and rods are inspected for dimensional tolerance, chemical composition, and thermal expansion coefficient before entering production. Automated forming lines shape the glass at temperatures exceeding 1,200°C, followed by precisely controlled annealing lehrs that eliminate internal stress. Post-forming, every unit passes through 100% visual inspection under standardized lighting, dimensional verification, thermal shock testing (-20°C to 200°C cycling), and leak-proof validation. Finished products are decorated using in-house screen printing, laser engraving, or decal transfer lines, then packed according to buyer specifications.

We hold a comprehensive certification portfolio: FDA 21 CFR for the U.S. market, LFGB §§ 30+31 and EU 1935/2004 for Europe, CPSIA for children's product compliance, RoHS for hazardous substance restriction, and CIQ for China export quality assurance. Our factory is BSCI audited and we welcome third-party inspection by SGS, Bureau Veritas, or Intertek.

With daily output of 100,000+ pieces across multiple parallel production lines, we are structured to handle large-volume export orders while maintaining flexibility for custom projects. Our Gold Member status on Made-in-China.com reflects our long-term commitment to transparent, trustworthy international trade.

Ethical & Sustainable Manufacturing

Our factory has successfully passed the BSCI (Business Social Compliance Initiative) audit, demonstrating our commitment to ethical manufacturing practices. BSCI certification covers fair wages, safe working conditions, reasonable working hours, prohibition of child labor and forced labor, and environmental responsibility. For European and North American buyers with corporate social responsibility (CSR) requirements, our BSCI compliance provides the necessary assurance that your supply chain meets international ethical standards.

In-Process Quality Control (IPQC)

Glass forming: Dimensional checks at regular intervals throughout each production shift
Annealing: Temperature curve monitoring to ensure proper stress relief in the glass
Lid assembly: Clip tension testing and gasket seating verification on statistically sampled units
Printing/decoration: Color accuracy measured against Pantone references; adhesion tested via cross-hatch tape test

Prototype Sampling

Mass Production

Pre-Shipment Inspection

First-article samples are produced for your evaluation and testing

Upon final sample sign-off, production begins with ongoing quality control and inspection

Final random sampling inspection (AQL 2.5 / 4.0 standard) before container loading

Trade Terms

Global sourcing only works when logistics are predictable. A great product stuck in customs or delayed at port is no product at all. At Jianmei, we've built our logistics around one promise: your shipment arrives when we say it will, in the condition we guaranteed.

Location Matters: Xuzhou sits at the crossroads of eastern China's transportation network. Within a day's trucking, we reach Shanghai, Ningbo, and Lianyungang — three of China's busiest container ports, offering frequent sailings to every major destination worldwide. This geographic flexibility means we can route your shipment through the port with the best combination of schedule, rate, and transit time.

The Right Shipment, The Right Way: Large-volume container order? FCL sea freight gives you the lowest per-unit cost. Smaller trial run? LCL consolidation keeps things economical without tying up capital in excess inventory. Urgent seasonal restock? Air freight gets products on shelf within 10 days. European buyer wanting a middle ground? The China-Europe Railway Express delivers in about two weeks at half the cost of air. We'll recommend the optimal mode, but the choice is always yours.

We Keep You Informed: From the moment your order enters production, you'll know where things stand. Production progress. Packaging completion. Container booking confirmation. Vessel departure. Estimated arrival. We communicate proactively because surprises in logistics are never good surprises.

If Something Goes Wrong: Despite everyone's best efforts, transit damage occasionally happens. When it does, we don't hide behind fine print. We respond quickly — providing photo documentation, facilitating inspection, coordinating replacements. Our track record of low damage rates (thanks to engineered packaging) means these situations are rare, but our response when they occur defines the quality of our partnership.

Mixed Orders Welcome: Building a product line? You don't need to fill a container with one SKU. Combine rectangular, round, and square lunch boxes. Mix capacities. Add water bottles or storage jars to the same shipment. One container. One set of documents. One arrival. Your product assortment, delivered together, ready for distribution.
