This guide is written for international buyers using Chinese marketplaces, buying agents, or parcel forwarding warehouses. It focuses on practical order evidence, warehouse checks, route eligibility, customs clarity, and shipping approval decisions before a parcel leaves China.

Short answer

If a Taobao seller shipped the wrong size, do not approve international forwarding until the warehouse evidence is clear. Compare the selected variant, order screenshot, seller message, product label, warehouse photo, domestic return window, and shipping cost before deciding whether to exchange, return, discount, or ship anyway.

Use this checkpoint as a practical record. Save the listing URL, selected variant, seller answer, domestic tracking number, warehouse photo, packing request, route decision, and final declaration note in one folder before the parcel leaves China.

That record makes later review easier for the buyer, warehouse, carrier, or customs team, and it prevents small details from being reconstructed from memory after export.

Confirm the mistake with evidence

Start with the order screenshot and selected option. Then ask the warehouse for a clear photo of the size label, hangtag, packaging sticker, or model number. A visual size difference is not enough; the buyer needs evidence that matches the seller page and the order record.

Decide inside the domestic return window

The best time to fix a wrong size is before the parcel leaves China. If the seller accepts returns, ask the warehouse or buying agent about domestic return cost and timing. If the item is low value, a partial refund or resell decision may be more practical than a return.

When shipping anyway makes sense

Shipping anyway can be reasonable when the size difference is minor, the item is low value, the buyer accepts the risk, or the return cost is higher than the product value. Record the decision so later support questions do not reopen the same issue.

Avoid repeat size mistakes

Save the size chart, seller measurement, selected option, and warehouse label photo for each clothing order. For shoes, check EU, US, UK, CN, and insole length. For kids clothing, confirm whether the size is height-based or age-based.

Final recommendation

Treat wrong-size Taobao orders as an evidence and timing issue. Resolve the seller mistake before export whenever value, fit, or resale matters. Once the item leaves China, exchange and return options become slower, more expensive, and less reliable.

Final Shipping Checklist Before Approving Dispatch

Before you approve international shipping from your China warehouse, run through this quick checklist: verify the customs declaration matches your actual order values, confirm the shipping method aligns with your timeline and budget, check that fragile items have adequate padding visible in the inspection photos, and ensure the total parcel weight matches your expectations. A two-minute review at this stage prevents weeks of customs delays or damage claims after dispatch. For more details, see our guide on DDP vs DDU shipping.

If your parcel contains items from multiple sellers or platforms, double-check that everything has arrived before requesting consolidation. Missing items discovered after shipping approval cannot be added to an already-dispatched parcel, and you will pay full shipping rates for a separate follow-up shipment.
