Superbuy Spread WikiSuperbuy shipping to the US | Estimate your parcel
Make one budget for the whole shipment. Save the destination, packed dimensions and date alongside each quote so you can rerun it when the parcel changes.
Build the subtotal from the order
Include the selected items, delivery to the warehouse in China, and any paid checks or packing services. Save the receipts in CNY. Convert them to USD for comparison with the freight and expected arrival charges, using the same conversion basis throughout your estimate.
Use the dimensions of the packed box
Compare routes with the same weight and dimensions. For example, 36 × 26 × 18 cm gives 16,848 cm³. With an illustrative divisor of 6,000 cm³/kg, that is about 2.81 kg of dimensional weight. A 1.8 kg box can therefore be priced above its scale weight. Use the route’s own divisor, weight rule and rounding when checking your quote.
Ask what the ZIP code quote includes
Compare routes to the actual delivery ZIP code, and check the final carrier and any surcharge for the address. Add international freight, optional coverage and any applicable duties, taxes or handling fees. Confirm with the carrier which import charges it collects up front and which could arrive later. Check the current CBP guidance before you rely on an estimate.
Check the contents before buying
Use the carrier and Superbuy restrictions for the exact product and route. Superbuy’s calculator lists perfume as prohibited for shipping. Keep your invoice and use accurate product descriptions and values for any customs information the service requests.
