double-walled glass cup

Introduction to Double-Walled Glass Cups

Double-walled glass cups are a modern innovation in drinkware, featuring two layers of glass with a vacuum-sealed air gap between them. This design provides superior thermal insulation, keeping hot beverages hot and cold drinks cold for extended periods without the outer surface becoming uncomfortable to touch. The cups are typically made from borosilicate glass, known for its high heat resistance and durability. Unlike single-walled glass, the double-wall construction prevents condensation on the exterior, ensuring a dry grip. These cups are widely used in homes, offices, cafés, and for specialty beverages like tea, coffee, and iced drinks. Their transparent design allows users to enjoy the visual appeal of their beverages, making them a popular choice for both functional and aesthetic purposes.

Purchasing Considerations for Double-Walled Glass Cups

When sourcing double-walled glass cups, buyers should evaluate material quality, insulation performance, and durability. Key factors include: ensuring the glass is borosilicate for thermal resistance, checking for a true vacuum seal, and verifying certifications like FDA or LFGB for food safety. Also, consider the cup’s weight, thickness, and whether it has a lid or handle. For bulk orders, request samples to test for breakage during shipping and assess the finish. Additionally, review the supplier’s production capacity, lead times, and after-sales support. Avoid suppliers with unclear return policies or low-quality control standards.

Product Pricing for Double-Walled Glass Cups

Pricing varies based on material, design, and order volume. Below is a general pricing table for reference.

Industry Standards for Double-Walled Glass Cups

Customs Data and Tariff Rates for Double-Walled Glass Cups

Customs classification for double-walled glass cups typically falls under HS code 7013.99 (glassware for table or kitchen purposes). Tariff rates vary by country: In the U.S., the duty rate is around 6% ad valorem under HTSUS 7013.99. In the EU, the rate is approximately 7% under CN code 7013.99. For China imports, tariffs are around 10% for finished goods. Additional duties may apply for anti-dumping measures. Importers should also consider value-added tax (VAT) in the EU (e.g., 20% in the UK) and sales tax in the U.S. (varies by state). Always verify current rates with customs brokers, as trade policies can change.

Why Choose Small and Medium-Sized Factories? Differences from Large Factories

Small and medium-sized factories (SMEs) offer several advantages for double-walled glass cup sourcing. They often provide more flexible customization options, lower minimum order quantities (MOQ), and faster response times. SMEs are also more willing to work with new buyers and offer competitive pricing for smaller batches. In contrast, large factories have higher production capacity, stricter quality control, and lower per-unit costs for massive orders. However, large factories may have rigid MOQs (e.g., 10,000 units) and slower communication due to bureaucracy. For buyers testing the market or needing unique designs, SMEs are ideal. For large-scale, standardized products, large factories are more cost-effective.
