Building the Perfect Haul: Weight Distribution Strategy

Shipping lines use tiered pricing: the first kilogram costs the most, and each additional 500g costs less per unit. This means a 3.1kg haul can cost almost the same as a 3.9kg haul because they are in the same tier. Strategic haul building means hitting the sweet spot at the top of each tier without crossing into the next expensive bracket.

Weight distribution also affects volumetric pricing. A haul with one heavy item and many light items will have worse volumetric efficiency than a haul with items of similar density. Our kakobuy spreadsheet 2026 includes a density calculator that warns you about inefficient mixes.

For EMS and most tax-free lines, the key tiers are: 0-1kg, 1-2kg, 2-3kg, 3-5kg, 5-10kg, and 10-20kg. The 3-5kg tier offers the best value per kg for most users. Target 4.5-4.9kg to maximize what you get for your money. For SAL and sea mail, larger hauls are more efficient per kg, so consider 8-12kg as your target.

The batch finder in our spreadsheet automatically suggests which items to combine to hit optimal tier weights. It considers item weight, packaging overhead, and your preferred shipping line.

Dense items like shoes, watches, and electronics help offset volumetric weight from bulky items like jackets and bags. A haul with 2 pairs of shoes (dense) + 3 hoodies (bulky) + 4 T-shirts (medium) usually has better volumetric efficiency than the same items rearranged differently. Place the densest items in the center of the package and bulky items around them.
