SuperBuy Freight Calculator: When to Choose Freight Over Parcel

If you are buying furniture, large quantities of clothing, or heavy accessories, freight is usually cheaper than parcel lines. The break-even point is typically around 15-20kg for sea freight and 10-15kg for air freight. Below those weights, parcel lines like EMS or DHL are more cost-effective. Freight is also the only practical option for items that exceed parcel line size limits, such as large suitcases or framed art. If your haul is borderline, use both calculators and compare the total.

To use the freight calculator, select freight mode in your warehouse. Enter the dimensions of your packed items. The calculator will show you the price per cubic meter. Because freight is slower, plan for a 3-6 week delivery window for sea freight and 2-4 weeks for air freight. If you need the items faster, parcel is better. The calculator also shows minimum volume requirements. If your items do not meet the minimum, you may need to add more items or switch to parcel.

Freight also has different customs rules. In some countries, freight shipments are more likely to be inspected. We recommend splitting very large hauls into two freight shipments to reduce risk. SuperBuy provides a consolidation service where they repack your items into freight-approved boxes. This consolidation can reduce your total volume by 20-30% by removing individual packaging and nesting items together. Always request consolidation for freight hauls.

Before you commit to freight, use the rehearsal shipping option. SuperBuy will measure your actual packed volume and update the calculator. This prevents the surprise charges that happen when buyers estimate their own dimensions incorrectly. For freight, even a small error in dimension estimation can change the cost by $50-100 because the price is tied to cubic meters, not just weight. Rehearsal shipping is the single best way to avoid freight billing surprises.
