4. Dimensional Weight and Shipping Strategy
Shipping cost is the most critical factor affecting profitability in hardware:
Dimensional Weight Formula
Formula: (Length × Width × Height in cm) / 5000 = DIM Weight (kg)
Carriers charge based on whichever is greater: actual weight or dimensional weight.
Shipping Optimization
- Box size optimization: Use the smallest appropriate box for each product group
- Combined shipping: Bundle multiple items in one package to reduce per-unit cost
- Regional carrier agreements: Negotiate special rates for high-volume regions
- Free shipping threshold: Set minimum cart value to increase average order (e.g., free shipping over $50)
- Heavy item surcharge: Clearly state separate shipping charges for paint cans, cement, etc.
5. Product Listing and Content
Technical information directly impacts conversion rates for hardware products:
- Specifications table: Dimensions, material, weight, power (Watts), RPM
- Compatibility info: "Compatible drill bit set for X brand drill" cross-references
- Usage videos: Short demonstrations showing how the product is used
- Comparison tables: Side-by-side model comparisons
- Professional photos: White background + in-use environment photography
- Barcode and brand info: GS1 barcode, brand logo, CE/UL markings
6. Marketplace Strategies
