How do I check whether a DHgate link is still the same batch?

Why

• Batch is a seller's word for a production run, and it is not printed anywhere you can read directly. What you can record are the markers that travel with a unit: the style code on the box label, the size tag inside the shoe, the code printed on a fragrance box, the serial on a device. Identical markers across two orders are the closest thing to a batch identity that a buyer can hold.
• Only photographs taken for you can be dated. A listing photograph can be reused for years, and a review photograph comes from somebody else's parcel. Ask for the marker and a coin or a ruler in the same frame, and keep the message thread, because that thread is the record a claim will read and the only one the seller cannot quietly replace.
• Price is a weak but real signal. A fall of a few per cent follows a coupon, a currency move or a quantity tier and means little. A fall of a fifth or more, with the same label and a different material named in the replies, usually marks a change of supplier rather than a discount, and the material check is the one that settles it.
• The marker that matters differs by category, and asking for the wrong one wastes the message. Footwear carries a style code and a size tag. Bags carry a date code stamped inside. Watches carry a caseback reference and a bracelet code. Fragrance carries a batch code that should appear on both the box and the bottle. A comparison run on the wrong field looks thorough and proves nothing.

When this answer flips

• The seller cannot photograph the marker because the unit is already boxed and sealed for dispatch, and offers the sealed carton with the label visible instead. That is weaker evidence rather than a refusal, and it moves the marker check from before dispatch to the unboxing on arrival, where you can photograph the same fields yourself.
• The markers match but the unit price has moved far enough to change the material. Ask for two photographs of the same panel, one under direct light and one in indirect daylight, and compare pore size and grain direction across a seam rather than trusting a code that is cheap to reprint on a new label.
• A second order is placed through a different storefront carrying the same label. Labels move between sellers along with surplus units, so matching text across two storefronts proves nothing on its own about who built the pair and on which line. What travels with the unit is the marker; what does not travel is the name above the door.

Three things to do next

1. Run the box label and SKU check against your order
2. Compare the current row against your earlier capture
3. Check which photo forms a claim will accept
