Short answer: To reduce size, colour and model mix-ups, send the exact variant text, code and quantity with the product link, then repeat those details in your warehouse instructions. Ask whether photos of the received item and its markings are available, and resolve discrepancies before approving international shipment. Written confirmation and photos can reduce ambiguity, but do not guarantee the correct variant or product compatibility.

Why variant mix-ups can happen
A single product page can contain several colours, sizes, model revisions or plug options. The product link alone may not identify the combination you want. Save the selected option text and any variant code with the order, rather than relying on the main listing image. A general warehouse photo may also leave a small size label or model marking unreadable.
Take particular care when option names are only numbers, an order contains several variants, or the seller reports that a requested option is unavailable. Ask the seller to confirm the exact selection and to contact you before any substitution. If an option is unclear, resolve it before payment.
Orders that need variant checks written down
- Apparel. Size and colour, especially where the size label is inside the garment and invisible in a folded photo.
- Footwear. Record the seller's size option and check the item and box labels against it; a size label alone does not establish fit.
- Electronics. Record the model revision, plug type and stated voltage requirements; visible labels do not establish safe operation or compatibility.
- Accessories and spare parts. Confirm the required connector, thread or other dimensions when versions look similar.
- Multi-unit orders. List the required quantity for each size, colour or model separately so the total does not hide a variant mismatch.
A clear variant confirmation message
Before paying, send the seller the option name exactly as written on the listing, the variant code if one exists, and a plain description. For example, a shoe order might specify "size 42, black, two pairs"; an appliance order might specify its model and plug option. Ask for a written confirmation that matches your selection, and retain it with the order record.
If the reply acknowledges the message without identifying the selected option, ask the seller to repeat the variant and quantity in text. Keep any agreed change in the same record. This makes later comparison clearer, but does not determine return eligibility or guarantee how a dispute will be resolved.
What the inspection note should say
Give the warehouse a list of observable details rather than a general "check the item" request. Confirm which checks and photos are available, whether there are extra charges, and any limits before relying on them:
- A close-up of the size or model marking on the received item, where accessible.
- The visible colour and packaging label; lighting and screens can affect colour appearance.
- The visible unit count for each requested variant, with any sealed or inaccessible contents noted.
- A photo of the plug or connector where accessible; compatibility or functional testing requires separate confirmation.
- Any visible mismatch or suspected substitution, raised for review before repacking or international shipment.
Use the current warehouse address and recipient details shown in your CNCartGo account. Storage is free for the first 100 days from the date the order is marked "Received". Days 101–200 cost USD 0.10 per parcel per day, with a maximum of 200 days in total. After 200 days, the parcel is treated as automatically destroyed and is no longer available for recovery or shipment. Check the storage days shown in your order while resolving a discrepancy; storage time does not extend a seller's return or exchange window.
When repacking helps and when it hurts
Repacking can change parcel volume and protection, but cannot correct the wrong variant. Resolve visible discrepancies before asking for packaging to be removed. Keep relevant labels, photos and original packaging while the seller or support reviews the issue, because these may be needed for a return or exchange request. Availability, cost and eligibility still depend on the order and applicable terms.
Check variants before consolidation
Consolidation combines selected parcels into an international shipment, so decide which items are ready before requesting it. If one variant is unresolved, ask whether to hold that parcel or proceed with the others, and confirm the resulting costs and shipping plan. Compare quotes for the actual parcel options: consolidation does not guarantee a saving, and the final weight, dimensions and route restrictions matter.
Costs, transit and what else to expect
For CNCartGo buying-agent orders, the service fee is currently 6–15% of the product order value. The first payment covers products, seller-to-warehouse delivery and the service fee. International freight is separate: it is confirmed after warehouse receipt and parcel measurement, using the actual or volumetric weight applicable to the selected route, and paid before dispatch. Check any requested inspection, repacking or storage charges as well. Delivery estimates depend on the available route, destination and current conditions; use the quote shown for your shipment rather than a fixed transit promise.
Four habits for clearer variant checks
- Record the listing option, variant code where available, plain description and quantity; ask the seller to confirm them.
- List each variant and its quantity separately, even when several variants share one order.
- Request the specific markings or photos you need and confirm the inspection scope and any charges.
- Compare the received-item information with the order, and ask about unreadable labels or unresolved differences before approving shipment.
The aim is a traceable record of the selected variant and the checks actually completed. Keep seller confirmations, order details and relevant arrival photos together, and raise discrepancies while the goods are still at the warehouse.
