A Chinese seller’s goods on Wildberries do not sit in Russia. They wait at a collection warehouse inside China and fly out against a specific order. The warehouse you pick sets both the delivery time and the rate — and that rate lands in the cost of every shipment, including the ones the buyer never collects.
The rate has two parts
Wildberries does not charge “per kilo” or “per parcel” but by both at once: a price for the weight plus a fixed price per order. Weight is rounded up to 100 grams. The formula in the official file reads: actual weight plus piece cost.
Take the Guangzhou warehouse on WB Standard: 58 ¥ per kilo and 2 ¥ per order on the light tier. A 270-gram parcel is billed as 300 grams: 58 × 0.3 + 2 = 19.4 ¥. The same parcel at 3,050 grams falls into the heavy tier — 43 ¥ per kilo and 8 ¥ per order: 43 × 3.1 + 8 = 141.3 ¥.
Two weight tiers
There are only two tiers: 0.1 to 0.3 kg and 0.4 to 20 kg. The difference is not cosmetic. On the light tier the kilo costs more but the per-order fee is almost nominal; on the heavy tier it is the other way round. For an item weighing about three hundred grams it pays to run both: sometimes trimming the packaging to stay in the light tier wins.
Four service types
- WB Express — the fastest at 10 days and the dearest: 89–122 ¥ per kilo.
- WB Plus — 6 to 13 days, 48–89 ¥ per kilo.
- WB Standard — 15 to 30 days, 58 ¥ on the light tier and 43 ¥ on the heavy one.
- WB Super Economy — the same rates as Standard, but the warehouses are spread wider across the country.
Size limits matter more than they look
Every warehouse has its own limit: the sum of three sides and the longest side. Most often that is 200 cm for the sum and 115 or 120 cm for a side, while the Hong Kong warehouses allow 90 and 60 cm. On top of that there is a general ceiling: 20 kg per piece and 100 Wh for anything with a battery. A parcel that fails on size will not travel, and finding that out at the warehouse costs more than checking beforehand.
Why look this up on our site
Wildberries publishes the rates as a single PDF whose name changes every time: 0726.pdf, 0826.pdf and so on. Links to the earlier files are collected nowhere, and the file itself is sometimes rewritten at the same address. We fetch it daily, parse it into a table, keep every past snapshot and show what changed at each warehouse against the previous version. We also sanity-check the data: if a rate or a size limit falls outside a reasonable range, we see it and do not publish it silently.
