The signature page
The packing menu, priced, with the arithmetic
Superbuy sells eleven things you can do to a parcel before it flies. Each one has a published price. Almost nobody reads the list as a list, which is how people end up paying twenty five yuan for corner protectors on a box of t-shirts and nothing at all on a box of ceramics.
The page below does two things. It prints the menu grouped by what the money actually buys, and it gives you a calculator that runs the same rules the prices are written in, so you can see the bill for your own parcel before you tick anything.
What the packing lines cost on your parcel
Type the billed weight and the number of items, tick what you are thinking of buying, and the bill updates. The per-kilogram lines have caps, and the priority line has a tier, so the total is rarely what you would guess by adding the headline prices.
If you also type the rate your shipping line charges per kilogram, the volume lines get a second answer: how many cubic centimetres they have to remove before they pay for themselves. We do not fill that rate in for you, because it is different for every destination and every line, and a number we invented would be worse than a blank box.
The calculator runs the published prices and nothing else. It does not know your route, your destination or what the carrier will bill. Prices read 2026-10-10 from the Parcel Value-added Service section of the help centre.
The eleven lines, and what each one is for
Grouped by what you are buying rather than alphabetically, because the groups are the decision. Only the first group can pay for itself; everything below it is insurance, convenience or presentation, and should be judged that way.
Every price, turnaround time and applicability note here is quoted from the agent’s own help centre articles, read 2026-10-10. Where an article gives a cap as well as a rate, both are printed.
Why only two of these can ever pay for themselves
Flattening a shoe box and vacuum packing textiles both do the same thing: they remove volume. Volume is billed at one kilogram per 6,000 cubic centimetres, so removing volume removes billed weight, so there is a rate at which the service is free.
Nothing else on the menu touches the bill. Corner protectors, foam filling, a wooden crate and moisture bags all make the parcel safer, and two of them make it slightly larger. The honest way to think about those is as an excess you are choosing to pay on a claim you hope not to make.
The packing video is in a third category again. It buys evidence. Five yuan is cheap for evidence if you are shipping something worth arguing about, and pointless if you are not.
The one service that changes how you are billed
Buried in the Shipping Expert article is a billing rule that is worth more than most of the packing menu. Superbuy states that parcels handled by a Shipping Expert use refund for excess and no supplementary payment for shortage, instead of the usual rule where you get a refund if the carrier charges less and a bill if it charges more.
It also states the service saves roughly 60 yuan on an economy small parcel and roughly 300 yuan on a standard express parcel, on its own historical order data, and commits to compensation up to 2,000 yuan per parcel if goods it processed are damaged in transit. Processing takes one to three working days.
Those are the agent’s own numbers and we have not tested them. What is checkable is the billing rule, and the billing rule is the part that is unusual in this market.
Buying protection, or buying insurance
Four of the packing lines exist to stop things breaking. Superbuy also sells a product that pays you if they break anyway, and the two are almost never compared, because they live on different pages.
SuperCare Plus launched in August 2026 and comes in two halves: a Value Preserver for total loss and a Safety Protector for damage. Either costs RMB 20 per parcel while the declared value is RMB 1,000 or less, and 2% of the declared value above that, with the flat fee as a floor. A declared value of RMB 200 works out at RMB 4 under the 2% rate, so the RMB 20 minimum applies instead.
Put next to the packing menu it reframes the question. Twenty five yuan of corner protectors reduces the chance of a claim. Twenty yuan of Safety Protector pays out when the claim happens. On a parcel worth a few hundred yuan those are close enough in price that the honest answer is usually both or neither, decided by whether the contents are replaceable rather than by what they cost.
| What you are buying | Price | What it actually does |
|---|---|---|
| Corner protectors | CN¥5 per kg, capped at 25 | Lowers the odds of crush damage. Pays nothing if damage happens anyway. |
| EPE loose filling | CN¥3 per kg, capped at 15 | Same, for impact rather than crush. Adds a little volume. |
| Wooden case | CN¥250 | Near-elimination of transit damage for heavy or high-value goods. Costs more than most parcels are worth. |
| Parcel Safety Protector | RMB 20, or 2% above RMB 1,000 declared | Pays out on damage in transit. Does nothing to prevent it. |
| Parcel Value Preserver | RMB 20, or 2% above RMB 1,000 declared | Pays out on total loss, which no amount of packing can prevent. |
| Delay | Not purchasable | Superbuy states there is no compensation for delay at all, because the mainstream couriers publish no delay standard. |
Packing prices from the Parcel Value-added Service section; SuperCare Plus rates and the delay statement from the insurance and compensation section of the help centre, both read 2026-10-10. The compensation clock starts when the parcel leaves the warehouse. Claims are paid to the account balance after customer service verifies them, and the agent lists force majeure, missing proof and a missed deadline as exclusions.
