Why you should confirm the data before relabeling, rather than shipping the goods first
Relabeling looks like it's just "tearing off the old label and sticking on your own," but in the actual operations of a China fulfillment warehouse, it is the step most prone to errors and rework. The reason is simple: warehouse operators are dealing with boxes of goods, and they can only rely on the written data you provide to determine "which box, which item, which label to apply." If the data itself is ambiguous, the risk of mislabeling transfers directly to your inventory and orders.
This article is intended for those who purchase from multiple suppliers in China and need to complete relabeling at a China warehouse before shipping toUnited Kingdomand overseas brands, importers, and e-commerce sellers in other markets, this article provides a relabeling data handover checklist. It does not involve any tax or compliance conclusions; it only addresses one search intent: before relabeling, exactly what data do I need to hand over to the China fulfillment warehouse?
Step 1: Establish a one-to-one correspondence between SKUs and physical items
Relabeling errors are, in the vast majority of cases, rooted in unclear SKU mapping. You need to first fill in the following columns in your own system before handing them over to the warehouse:
- Supplier SKU / Factory item number：The number printed on the outer carton or inner packaging by the supplier when shipping.
- Your internal SKU: The number you want to ultimately use in the inventory and order system.
- Product name and specifications: Color, size, capacity, version, etc., used for manual verification.
- Quantity: List the quantity that should arrive at the warehouse for this shipment by SKU.
- Corresponding new label files: Which label image or which barcode data segment each SKU corresponds to.
If the same supplier item number corresponds to multiple internal SKUs (for example, the same style in different colors), you must split them into multiple rows in the table and specify whether the distinguishing factor is color, size, or a certain field on the packaging. Do not use vague descriptions like "same style"; the warehouse cannot make a judgment based on that.
Step 2: Clarify the Handling Rules for Old Labels
How to handle old labels must be clearly stated in the relabeling instructions. There are three common situations:
| Old label situation | Suggested resolution | Information we need you to confirm |
|---|---|---|
| The old label contains a supplier barcode, which will conflict with the new label | Cover or remove the old label | Is covering allowed, and can it still be scanned after covering |
| The old label contains price or promotional information | Must be removed or covered | Is residual adhesive residue allowed |
| The old label is a neutral label and does not affect scanning | Can be kept, just affix the new label on top | New label placement position |
If the old label is printed directly on the packaging (e.g., printed on a color box) and cannot be removed, you must specify in advance whether to "cover it" or "accept the old information being visible." Only you can make this kind of decision; the warehouse will not decide for you.
Step 3: Content of the New Label and Barcode Position
The new label data must be specific enough to be actionable, and must include at least:
- Barcode type and content: For example, EAN, UPC, or a custom barcode, along with the corresponding numeric string.
- Label size: Length and width, to avoid the warehouse printing at default dimensions and the label not fitting or covering up information.
- Placement position: Whether it goes on the outer carton, inner box, or the product itself; front, side, or bottom.
- Orientation requirements: Whether the barcode must be horizontal and whether rotation is allowed.
- Whether covering other text is allowed：For example, whether it may cover the ingredient list or instructional text.
For label files, it's recommended to provide printable vector files or high-resolution images, along with an "SKU—label file" reference table. If the same SKU uses different labels in different batches, distinguish them by batch — do not mix them up.
Step 4: Overlay Rules and Spot-Check Requirements
Relabeling isn't done just because the label is applied — you need to define acceptance criteria:
- Coverage Rules：Whether the new label must completely cover the old barcode; whether the old barcode is allowed to be partially visible.
- Spot-Check Ratio：For example, spot-check by carton or by SKU; the specific ratio is up to you based on risk.
- Photo Requirements：Whether photos must be taken after relabeling for record-keeping, and whether to shoot a full view or a close-up of the barcode.
- Handling of Non-Compliant Items: When misapplied labels, crooked labels, or unscannable barcodes are found, should they be reworked or isolated separately?
Once these requirements are written into the instructions, the warehouse can execute to the same standard, rather than each operator interpreting them differently. Basic quality inspection and photography are standard capabilities of China fulfillment warehouses, and the archived photos after relabeling can be merged into the same record-keeping process. For details, please refer to China Warehouse Fulfillment Services work instructions.
Step 5: Exception Handling Process
Common exceptions during relabeling and recommended ways to handle them:
- Physical items do not match the SKU list: Isolate this batch first, take photos and report back, wait for your confirmation before proceeding—do not make assumptions on your own.
- Label file missing or unable to print: Pause relabeling for this SKU; other SKUs can continue.
- Old labels cannot be removed and cannot be covered over: Isolate the entire batch; you decide whether to repackage or return.
- Quantity less than expected: Relabel according to the actual received quantity, and note the discrepancy in the records.
Writing exception handling as a process is more effective than assigning blame after the fact. You can run a small-batch trial on your first collaboration, and once data handover and acceptance standards are running smoothly, then scale up the batch size.
Relabeling Data Handover Checklist (Ready to Copy and Use)
- Supplier item number and internal SKU cross-reference table (including specifications and quantities)
- New label files and barcode content corresponding to each SKU
- Label size, placement position, and orientation requirements
- Old label handling rules (cover / remove / keep)
- Cover-up rules and whether old barcodes may remain exposed
- Sampling ratio and photo requirements
- Rework or quarantine rules for non-conforming products
- Exception feedback contact and response method
If relabeling is done well, subsequent picking, packing, and international shipping will all go smoothly; if done poorly, problems will only surface on the order side. Confirming the data upfront is the lowest-cost approach. If you'd like to discuss your relabeling scenario, you can reach us via Contact Us Explain the SKU structure and labeling requirements.
Reminder on Customs Clearance and Taxes
After relabeling is completed, when the goods are shipped to the destination country, the following may be involved:customs clearanceand taxes. Customs and tax authorities in different countries or regions have their own regulations for imported goods, and these may be adjusted at any time. We recommend that you directly check the latest official requirements published by the destination country's customs or tax authority, or consult a locally licensed professional, to obtain accurate information applicable to your specific situation. This article does not provide any conclusions regarding tax or customs clearance operations.
