China shopping-agent shipping calculator for United States

Agents charge by chargeable weight — the greater of your parcel's actual weight and its volumetric weight (length × width × height ÷ a divisor such as 5000 or 6000). Most lines use a first-weight price plus a continued-weight rate per additional step, and the price varies by destination, line and item category.

There is no single per-kg price. Many lines charge a higher first-weight amount, then add a per-kg or smaller billing-step rate; volumetric weight can also replace actual weight for bulky parcels. Enter the destination, weight and dimensions in the calculator to compare the usable lines for that parcel.

Volumetric weight estimates how much space a parcel takes rather than how heavy it is, calculated from its dimensions divided by a carrier divisor. When a light parcel is bulky, the volumetric weight can exceed the actual weight and becomes the chargeable weight you pay for.

It depends on your weight, dimensions, item category and destination. Shopwaver ranks the usable lines from Mulebuy, Oopbuy, Litbuy, Kakobuy, Hipobuy, USFans, Sugargoo and Hoobuy for your parcel so you can see which is lowest, using rates aggregated from public data with an update time.

Each line has weight and size limits, and some carriers only accept parcels above or below a threshold. Lines that can't carry your parcel are hidden so the comparison only shows options you could actually use.
