Hardshell Suitcase

Material Composition Assumptions

This assessment covers hardshell suitcases with typical carry-on dimensions and an average weight of 3 kilograms. The primary shell consists of polycarbonate plastic comprising approximately 1,800 grams or 60% of the total weight. Alternative shell materials include polypropylene or ABS plastic at similar proportions. Synthetic rubber wheels account for roughly 300 grams or 10% of the product weight. Aluminum tubing used for the telescoping handle and frame structure represents about 450 grams or 15% of the total mass. Interior fabric lining made from nylon or polyester contributes approximately 240 grams or 8% of the weight. Plastic zippers and metal locking mechanisms comprise the remaining 210 grams or 7% of the suitcase components.

Manufacturing Geography

The majority of global hardshell suitcase production occurs in China, specifically concentrated in the Baigou region which accounts for more than 70% of worldwide manufacturing capacity. Chinese factories benefit from established supply chains for plastic pellets, aluminum extrusion, and component assembly operations. The country’s grid intensity of 554 grams of carbon dioxide per kilowatt-hour significantly influences the carbon footprint of energy-intensive manufacturing processes. Production facilities in this region have developed specialized expertise in injection molding techniques required for hardshell construction and maintain integrated operations that reduce transportation costs between component suppliers.

Mexico	458 gCO2/kWh	39	-7%

Provenance Override Guidance

1. Provide detailed material composition data including the specific types and quantities of plastic resins, recycled content percentages, and alternative shell materials used in production.

2. Submit factory-specific energy consumption records showing actual electricity usage per unit manufactured, including any renewable energy procurement or on-site generation capabilities.

3. Document transportation logistics with specific shipping distances, modes of transport, and packaging specifications from raw material suppliers through final distribution points.

4. Supply component sourcing information detailing the origin and manufacturing methods for wheels, zippers, handles, and locking mechanisms used in assembly.

5. Provide end-of-life planning documentation including recycling programs, material separation protocols, or take-back initiatives implemented by the manufacturer.

Methodology Notes

• The CCI score represents cradle-to-gate emissions covering raw material extraction through factory completion but excludes consumer use phase and transportation during travel.

• Scope 3 emissions dominate the carbon footprint due to upstream plastic production processes that require significant energy inputs for polymerization and pellet formation.

• The functional unit assumes a standard carry-on hardshell suitcase with typical durability expectations of 5-7 years under normal usage patterns.

• Manufacturing emissions include energy-intensive injection molding processes, component assembly operations, and quality testing procedures performed at production facilities.

• Data gaps exist around specific recycling rates for hardshell suitcases and the carbon benefits of using recycled plastic content in new production cycles.

• The assessment excludes consumer transportation to purchase locations, packaging materials beyond basic protective wrapping, and retail storage emissions.
