Price Comparison and Value-Based Sourcing

While pricing is a key factor, focusing solely on unit cost can lead to hidden expenses related to defects, delays, or rework. Instead, adopt a total cost of ownership (TCO) approach when comparing suppliers.

Understanding Price Variations Across Suppliers

Camper window prices typically range from $25 to $120 per unit, depending on:

• Material type (acrylic vs. tempered glass)
• Frame construction (aluminum, PVC, or composite)
• Sealing technology (double gaskets, EPDM rubber)
• Customization level (size, shape, opening mechanism)
• Order volume and packaging requirements

For example:

• Ningbo Homful may quote $45/unit for standard sliding windows at 1,000 units, leveraging economies of scale.
• Shenzhen Tianya Tongxing might charge $65/unit for similar specs but includes UV-coated glass and enhanced weather stripping—adding value for premium RV models.
• Longkou Yongan could offer $32/unit, appealing for budget-conscious buyers, but additional costs may arise from higher rejection rates or extended shipping timelines.

The takeaway? Lower initial quotes don’t always translate to savings. Factor in:

• Quality failure rates
• Warranty coverage
• Shipping and import duties
• Support for returns or replacements
