Before printing private-label press-on nail packaging, connect each retail pack to three separate records: the supplier's design reference, your own inventory SKU and, where required by your sales channel, its GTIN and barcode artwork. Confirm that mapping before approving cards or boxes. A barcode that scans can still identify the wrong product.
For a press-on nails wholesale order, this is the step between choosing designs and sending packaging files. It is especially useful when several styles share the same branded card: the logo stays the same, but the product information may not.
Start with the pack you will sell
Write down what the customer buys as one item. Identify the nail design, shape, length, confirmed size assortment, piece count and included accessories. A set of nails, a set with accessories and a multipack should not be casually combined in one order line.
Use the retail kit contents guide if those details are still open. You do not need a finished label to request a quote, but the supplier should be able to see which decisions remain unresolved.
The photograph above shows design samples on display cards. It illustrates the limited space around the nails; it is not an example of barcode-verified retail packaging.
Keep the supplier reference, SKU and GTIN separate
The supplier reference tells the supplier which design you mean. Keep the catalog filename and collection beside it, particularly when selecting from more than one workbook. Do not assume that a style code doubles as your retail barcode.
A SKU is your internal stock-keeping reference. A GTIN is a globally unique trade-item identifier. The barcode is the scannable symbol used to carry identification data. GS1 US explains the distinction between SKUs and GTINs, including why product variants need to be considered individually.
You can retain the supplier reference in your purchasing sheet while using a different SKU in your own inventory system. The important part is keeping the relationship visible. If staff need to open a chat history to learn which nail set belongs to a label, the record is not ready for packing.
Agree who provides the identifiers
For branded products, GS1 says the brand owner normally assigns the GTIN. That can be the business commissioning a private-label product, even when another company manufactures it. Confirm responsibility with your brand's GS1 organisation and trading partner before sending artwork.
Ask the retailer or marketplace which identifier and label format it requires. Keep its written requirement with the project. A request for a barcode position does not establish that your identifier, product listing or pack has been accepted.
SENAILGLOBAL reviews barcode and label requests as part of the packaging brief. Feasibility and scope need confirmation in the quote. Printing your card does not include an assumed GTIN licence, marketplace approval or fulfillment-preparation service.
If you are reselling an unchanged, already-branded product, do not replace its identifier merely to make it match your own SKU. Resolve the identification requirement with the brand owner or trading partner first.
Give separately handled variants their own rows
A shared design name is not enough to identify everything in a collection. A short version and a long version can look similar in a small photograph. Size options, different kit contents or a different saleable pack can also matter when staff pick an order.
List these versions separately in your working record, then confirm the applicable GTIN assignment rather than guessing from the artwork. Do not assume either that every packaging revision needs a new GTIN or that one number can cover the entire collection.
For a repeat order, record whether you are repeating the same retail item or changing it. A nail change, pack-content change and cosmetic artwork correction are different questions. Review the applicable identification rules before reusing the old print file.
This also makes quantities easier to check. Count the labels needed for each confirmed product version, not just the number of nail sets across the whole order. A correct total does not prove that each version has enough cards.
Send one label record per retail item
Use the following as a blank working record. It is a suggested purchasing aid, not a finished SENAILGLOBAL product specification or a sample customer order.
- Supplier catalog file, collection and design reference:
- Your product name and internal SKU:
- Shape, length, size assortment and confirmed pieces per pack:
- Included accessories and outer packaging:
- Target country, sales channel and written label requirement:
- GTIN, responsible brand owner and approved barcode artwork file, if required:
- Card or box artwork filename, language and revision:
- Quantity for this exact product and label version:
- Remaining questions, approval owner and approval date:
Keep the identifier as text when preparing a spreadsheet so a leading zero is not lost. Check the exported file as well as the working sheet. The number sent to the printer should match the approved product record, character for character.
The custom printed nail-card guide covers the separate artwork brief: material, dimensions, print versions and what stays visible once the nails are attached.
Check the data and the physical print separately
First, compare the approved product record with the number encoded in the barcode and the digits printed below it. Confirm the design reference, SKU, product description and intended pack. A successful scan of a different product's number is not an approval.
Next, review the printed sample on the actual assembled pack. Check the proposed position with the nails, sleeve, sticker, fold and closure in place. Keep these practical checks distinct from deciding who owns the number.
GS1 US's placement and printing guidance calls for suitable high-resolution artwork, appropriate contrast and clear margins around the symbol. It warns against cutting down barcode height or casually resizing artwork to fit a gap. Give the printer the required symbol and application details; do not invent one universal barcode size for every nail card.
Ask your trading partner what scan testing or verification evidence it requires, and agree who will arrange it. Keep that result with the exact print revision tested. A screenshot, a phone scan and approval of the nail design should not be substituted for whatever evidence the receiving channel actually requires.
Finally, check the pack-out instruction: which label goes with which nail set, how versions are separated and how the final quantities are reconciled. Use the packaging proof checklist for the remaining material, print and assembly checks.
Build the quote around the confirmed label scope
For SENAILGLOBAL, start with the current catalogs, then send your selected item references and quantities. Existing designs, new custom designs and packaging minimums are separate questions. Item prices vary by design and collection; packaging, accessories and freight are confirmed separately.
Include the label record above in your private-label inquiry. Tell us whether you have approved barcode artwork or are still confirming the channel's requirements. State whether you need a printed proof, an assembled pack for review, or a feasibility discussion before artwork starts. Packaging support accompanies nail orders; standalone label supply is not promised.
A nail sample and a packaging proof answer different questions. Request a design sample when you need to assess the nails, and describe any packaging-proof requirements separately. The useful outcome is a quote in which each design, quantity and packaging version can be traced to the same agreed record.
