Rowbuy after-sales pairs: sorting each problem by when it shows up
Five pairs for when something is wrong. Rowbuy's returns article is short, and almost everything in it depends on one question: did you see the problem before the parcel left China, or after it reached you?
Caught in QC versus discovered after delivery
Caught in QC
Wrong or damaged item visible in the warehouse photos. Raise it before shipping.
QC review in your accountDiscovered after delivery
Lost or damaged in transit, found at home. Goes to support, with photos and the order number.
Support, after deliverySwap costapproving photos quickly and turning a seller problem into a carrier claim with a longer, less certain timeline.
Rowbuy's returns article has two paragraphs and they map onto this pair exactly. The first says a wrong or damaged item seen in QC should be raised before shipping, and that Rowbuy will then try to sort out a fix with the seller, "where possible". The second covers trouble found after delivery: support wants the order number and photos, and offers help with a claim. It adds that refund timelines depend on the seller and the carrier.
Notice who is on the other side in each case. Before shipping it is the seller, who is still a short courier ride away. After delivery it is a carrier, possibly two, across a border. Keep the unboxing photos, the outer box and the label until you have checked every item. A claim without them is hard to make.
A note on the other returns page: Rowbuy's footer also links a "Returns and Refunds" blog page with a 30-day retail policy written for a flag shop. It does not describe agent orders, and the help article above is the one that fits.

Return and replacement
Return
The seller takes the piece back and refunds it, on a schedule the seller sets.
Raised from QC reviewReplacement
The seller sends a corrected item, which arrives, is Stored and photographed again.
Raised from QC reviewSwap costasking for a replacement on an item whose storage clock is nearly out, or a return when the seller has no stock left.
Rowbuy offers to help arrange either, with the words "where possible" attached. Nothing in its pages promises one or the other, and the seller decides. That makes the choice yours to state clearly when you raise the concern.
Pick a return when the listing itself was wrong (photos that do not match the product) or when stock on the product page was already low; one frame on our shelves showed only five in stock. Pick a replacement when the listing was right and your copy was faulty. Either way, the domestic courier leg back to the seller may cost something, and Rowbuy does not publish who pays it. Ask before agreeing.

Restricted on one line and prohibited everywhere
Restricted
Allowed on some lines or to some countries only: batteries, liquids, flammables, perfume.
Help: "Customs, duties & prohibited items"Prohibited
Not forwarded or shipped at all: weapons, meat, cash and gold, live animals and plants, and more.
Help: "Prohibited & restricted items"Swap costbuying a battery-powered gadget for a country where no line carries it, then paying to store it until it is disposed of.
Rowbuy's customs article frames the first group: some items cannot ship internationally "depending on the line and destination", and when a parcel holds something your chosen line will not take, Rowbuy says it will flag it so you can pick an alternative. Its long prohibited list frames the second group, and it is broad: it covers perfume and alcohol, batteries and power banks, aerosols, powders, medicines without approval and many medical devices.
Perfume shows how blurry the edge is. It sits in the dangerous-goods list, then gets its own paragraph saying to choose sea freight where available and that some routes allow domestic forwarding only. Watches carry a button cell. Before buying anything with a battery, liquid or powder, ask support whether any line accepts it for your destination. Separately, Rowbuy's own pages list counterfeit and IP-infringing goods as items that cannot be bought or shipped through it.

Import duty and shipping fee
Import duty and tax
Set by your country's customs. Paid by you, the buyer.
Help: customs articleShipping fee
Set by the line you choose. Paid to Rowbuy after QC.
Estimator and parcel screenSwap costtreating the freight bill as the last payment, then refusing a parcel that arrives with a duty demand.
Rowbuy's customs article is plain on who decides: the amount comes from your own country's customs, not from Rowbuy, and paying it falls to the buyer. The freight payment never includes them, and no page we read offers to pre-pay duty.
So the full cost of an order has four parts, not three: goods, service fee, freight, and whatever your customs charge on arrival. The fourth depends on your country's rules and the value declared for the parcel, and we do not try to predict it here. Put a margin in the budget, and if your country collects duty through the courier, keep that money ready on delivery day rather than letting the parcel sit.

Tax-friendly line and guaranteed outcome
Tax-friendly line
A line Rowbuy describes as designed to reduce customs friction.
Help: customs article, second sentenceGuaranteed outcome
Something Rowbuy explicitly does not offer: "we can't guarantee any specific outcome."
Same sentence, second halfSwap costpicking a line for its label and treating a duty bill as Rowbuy's mistake.
The phrase comes from the same customs article: "Tax-friendly lines are designed to reduce customs friction, but we can't guarantee any specific outcome." In the line data we replayed on October 22, none of the three lines carried that label in English, and the estimator showed only internal Chinese line names, which we do not repeat.
Read "tax-friendly" as a hope about paperwork, not as a promise about your bill. If the difference matters to you, ask support which line it means for your country and what it changes. Get the answer in writing, in the support thread.
