Material Selection Risk Overlooking the durability and weight differences among materials like ABS, Polycarbonate, and Aluminum often leads to customer dissatisfaction and increased returns, so carefully evaluate the trade-offs between toughness and lightness.
Specification and Product Type Alignment Insist on matching the luggage size (20, 24, 28 inch) with the intended use, such as carry-on or checked baggage, while also clarifying the product type—whether it's a suitcase, trolley, or duffel—to ensure it fits your target market's travel habits.
Industry Norms on Wheel Systems In practice, most suppliers favor spinner casters for maneuverability, but understanding the differences between spinner, double wheels, built-in, and external casters will help you negotiate the best balance between mobility and durability.
Hardness and Cost Impact The choice between soft, medium soft, partial hard, and hardside luggage can account for up to 30% of total cost variations; selecting the appropriate hardness level directly affects manufacturing complexity and retail pricing strategy.
