Barometer tools: parcel forecast and bulk calculator
Three small tools built on this site's own data. The forecast replays real Whalebuy estimator quotes taken on October 24, 2026; the bulk calculator does the volumetric arithmetic for any box; the storage clock works out the free-storage, extension and return dates from one status date.
Parcel forecast by reading and country
Pick a destination and one of the four parcel profiles that stand in for our weather shelves. The tool lists up to four of the lowest carriable lines the estimator returned, with the weight each line charged and the transit time it gave. It is a snapshot: freight prices change, so use it to compare shapes and seasons, then run your real parcel through the official estimator, which you can Run the Whalebuy estimator at any time without an account.

Bulk calculator for any box
Enter the packed carton’s three sides in centimetres and its scale weight in kilograms. This calculator shows divisors 8,000, 6,000 and 5,000 and rounds up to 100 g as the saved estimator results did. A volumetric result above the scale weight identifies a possible size penalty. A smaller carton may reduce it, but only compare prices after checking the actual route’s divisor, restrictions and packing needs.

Storage clock for seasonal orders
Weather buying often means buying early. Enter the warehouse status date and the clock applies the published storage and return periods shown here: 90 free storage days, extension requests from day 60, a six-month ceiling with extensions at CNY 10 per product per month, and a 120-hour return window if that date is also the stocked-in date. Check the actual status and time in your account: a received date and a stocked-in date may differ, and this date-only tool cannot settle an hour-specific deadline. A desired arrival date is a planning prompt, not a delivery promise. See status terms before choosing the input.

How the numbers were gathered
On October 24, 2026 we sent forty requests to Whalebuy's public estimator: ten countries times four box profiles, with no product category selected. For each we kept the lines marked as carriable and sorted them by the dollar price shown. Lines the estimator listed but refused, for size or capacity reasons, are left out. The United States loose winter box is the extreme case: only UPS-based lines remained, and their express versions charged it at 8.5 to 12 kg.
The storage and return rules come from Whalebuy's storage article, its value-added services list and its return and exchange rules. The stage times in the shelf pages come from its order processing and domestic delivery articles. None of this is official advice; it is our arithmetic on their published numbers, and the official pages win where they differ.
