Private Label Lash Specification Sheet: Free Template
A private label lash specification sheet turns a product idea into one controlled document that a supplier can quote, sample, approve, produce, and repeat. Instead of relying on product links or scattered messages, it records exactly which lash fibers, curls, diameters, lengths, tray components, packaging files, and approval references belong to each SKU.
This guide explains the fields that matter, where different lash formats need different specifications, and how to build a copyable template for a first order or reorder. It is written for lash brand owners, wholesale buyers, educators, and salon teams preparing a supplier brief.
Quick Answer
A useful private label lash specification sheet has five layers: document control, a master SKU matrix, product construction, tray and packaging details, and approval/change-control records. Give every revision a unique number and date. Connect every SKU to an approved sample or other agreed evidence, but do not treat the sheet as a substitute for a quotation, purchase order, quality inspection, safety documentation, or legal review. Supplier terminology and capabilities vary, so the current written agreement for your exact project controls.
What a Private Label Lash Specification Sheet Does
A specification sheet is the product's controlled description. It gives the buyer and supplier one place to check what is being discussed before a quote is accepted. It can also reduce avoidable ambiguity when a sample is revised, a purchase order is raised, or a successful SKU is reordered months later.
The sheet should answer questions that a product title cannot. “0.07 CC mixed tray” does not state the material terminology, finish, length range, row count, row sequence, strip behavior, backing card, case, label position, barcode, or approved artwork revision. A complete record makes those details visible.
This is different from choosing a sourcing model. If you are still deciding how much development you need, compare white label vs private label lashes and review the separate OEM vs ODM lash guide. Use the specification sheet after the intended deliverables are clear.
Spec Sheet vs Quote, PO, Artwork, and QC Record
No single file should be asked to do every job. Link the specification to the commercial and quality documents that control the order, while keeping their responsibilities distinct.
| Document | Primary Job | Typical Contents | What It Does Not Prove by Itself |
|---|---|---|---|
| Specification sheet | Define the intended product and revision | SKU fields, construction, components, approved references, change rules | Price, availability, compliance, safety, or conformity of delivered goods |
| Quotation | State the supplier's commercial offer | Price, MOQ logic, setup charges, lead-time basis, shipping terms, validity | That every product detail is correctly understood |
| Purchase order | Authorize a defined order | SKU, quantity, price, delivery details, referenced specification revision | That artwork and physical references are current unless linked |
| Artwork pack | Control printable graphics | Dielines, fonts, colors, barcode data, filenames, proof approvals | Product construction or market compliance |
| Inspection record | Record what was checked in a lot | Sample plan, observations, counts, photos, disposition | Universal quality or performance beyond the checks performed |
Use the same specification ID and revision on the quotation, purchase order, approval form, and inspection record. That small habit makes it much easier to identify which instructions were actually accepted.
Start With Document Control
Place a control block at the top of the file. Include the brand or legal buyer name, project name, supplier, document owner, specification ID, revision number, issue date, status, and approval names or roles. Use clear statuses such as Draft, Submitted for Quote, Submitted for Sample, Approved for Production, Superseded, and Archived.
Never overwrite the only approved copy. When a field changes, create a new revision and record the reason. A simple change log should show the revision, date, affected SKU or section, change summary, person requesting it, supplier acknowledgment, sample requirement, and final approval.
Control filenames too. A name such as lash-spec-final-new-2 will become confusing; a structured filename such as Brand_ProductFamily_SPEC_Rev03_2026-09-10 is easier to trace. Store approved files in one shared location with read-only archived revisions where practical.
Define the Project, Intended User, and Claims
Begin the product brief with its intended user and use. State whether the product is for trained professional application, salon retail, education, or at-home cluster use. Do not place professional extension adhesive fields into a lash tray template or treat a DIY kit like an individual-extension tray; these categories can have different instructions, documents, risks, and market requirements.
List the target product family, visual result, expected assortment, sales markets, packaging languages, and channels. Mark marketing claims as “proposed” until supporting evidence and appropriate review are complete. Terms such as cruelty-free, vegan, hypoallergenic, medical-grade, non-irritating, sustainable, fixed retention, or a guaranteed wear time should not enter approved packaging merely because they appear in a competitor listing.
Material names also need definition. “Mink,” “silk,” and “cashmere” may be catalog or finish terms rather than literal material declarations. Review what lash extensions are made of, then ask the supplier to state what its terms mean and what evidence supports any composition claim.
Build One Master SKU Matrix
The SKU matrix is the index for the entire project. Give every sellable combination a unique buyer SKU, even if several combinations share one tray case or artwork family. This prevents a mixed tray, single-length tray, curl, diameter, or fan dimension from being hidden inside a product nickname.
| Buyer SKU | Product Family | Diameter / Dimension | Curl | Length Plan | Rows / Units | Pack Code | Status |
|---|---|---|---|---|---|---|---|
| VL-003-CC-MIX | Handmade volume tray | 0.03 mm | CC | Mixed; row sequence listed separately | 16 rows | CASE-A / CARD-02 | Sample revision |
| PF-5D-D-12 | Premade fans | 5D; fiber diameter specified below | D | 12 mm single length | Quantity and row layout specified below | CASE-B / CARD-07 | Draft |
| CL-D-CAT-01 | DIY lash clusters | Cluster width and band fields below | Supplier-defined code plus approved reference | Mapped assortment by unit count | Cluster count by length | KIT-C / TRAY-04 | Concept |
These rows are structural examples, not recommended assortments or supplier offers. Build your own matrix from verified options and a current quotation. The mixed vs single-length tray guide can help you decide whether a compact mixed assortment or deeper single-length inventory suits the launch.
Record the Core Lash Tray Specifications
After the matrix, create a detailed product block for each family. Record the supplier's fiber or material description, color, finish, diameter, curl code, individual or mixed length, row count, row-by-row length sequence, and any measurement method that the parties have agreed to use.
Do not assume that the same named curl looks identical across suppliers or product families. Connect the written code to a labeled sample and comparison images taken in a repeatable position. Use the eyelash extension curl guide, diameter guide, and length chart to build informed questions, not to replace the supplier's actual product specification.
For mixed trays, state every row in order. “8–15 mm mixed” is incomplete if the buyer expects two rows of popular lengths or a particular progression. For single-length trays, confirm whether all rows use the same labeled length and how row labels appear.
Add Fields for Each Lash Format
Keep a shared core, then add format-specific fields. A single generic template can hide the construction details that matter most.
| Product Format | Additional Fields to Define | Reference to Approve | Common Ambiguity to Remove |
|---|---|---|---|
| Classic or handmade volume tray | Fiber count presentation, finish, taper description, strip tack, spacing, foil or paper backing | Labeled tray sample and pickup evaluation | Whether a marketing finish name describes appearance or material |
| Premade fan | D count, fiber diameter, fan width or spread convention, stem/base profile, bonding method, fans per unit | Approved fan sample plus agreed viewing method | What “narrow,” “wide,” “pointy,” or “short stem” means |
| DIY cluster or kit | Cluster width, band profile, fibers per cluster if controlled, length assortment, units per length, tray map, included tools or liquids | Complete assembled product and component list | Whether quoted quantity means clusters, rows, trays, or full kits |
| Liquid or professional adhesive | Use a separate formula-controlled brief covering exact identity, fill, container, label, instructions, lot coding, shelf-life basis, storage, SDS and required market documentation | Current formula and packaging approvals, not a lash tray sample | Treating a product name or old SDS as proof for the received formula |
For premade products, review heat-bonded vs glue-bonded premade fans before writing a bonding-method field. For finish language, the matte vs glossy lash guide explains why the visible result and supplier terminology should be verified rather than assumed.
Specify the Strip, Tray, and Unit Packaging
A lash specification continues beyond the fibers. Record strip width, color, backing type, tab shape, adhesive behavior expected during approved pickup testing, row spacing, printing, and placement on the backing card. State tray dimensions, material, color, closure, row capacity, and how the tray sits inside the case.
Give each packaging component its own code: tray, case, backing card, insert, seal, label, length sticker, barcode label, and shipping carton. Reference the correct artwork filename and revision for every component. The custom lash packaging checklist covers dielines, print proofs, barcodes, finishes, and label review in more depth.
Packaging statements depend on the intended sales market. Confirm required identity, responsible business information, quantity, warnings, instructions, language, traceability, disposal marks, and other applicable details with qualified advisers. Supplier approval or a visually correct proof does not establish legal compliance.
Connect Samples, Photos, and Approval Evidence
Write the sample ID, date received, supplier batch or lot when available, and decision beside each affected SKU. Keep labeled photos under consistent lighting and angles. If a physical golden sample becomes the production reference, identify who retains it, how it is sealed or labeled, and how long it remains available.
A stock sample can screen a product family, while a custom sample or complete packaging proof may be needed to approve the final private-label configuration. The wholesale lash sample testing guide provides a step-by-step evaluation record.
Record the limits of every approval. Approving curl appearance does not automatically approve strip tack, packaging color, barcode data, or a future material substitution. A photo can support a decision, but it may not show dimensions, handling, or finish accurately enough to replace a physical sample.
Define Acceptance Criteria Without Guessing Tolerances
Replace “premium quality” with observable checks: correct SKU and label data, row count, length sequence, visible curl consistency against the agreed reference, tray assembly, case condition, fan count or cluster assortment, base appearance, print placement, and absence of obvious contamination or damage.
Do not invent a universal tolerance, test method, or AQL. Agree in writing on what will be measured, how, under which conditions, on how many units, and what happens when a result is outside the accepted range. A tolerance copied from another product or factory may be unsuitable for your materials, equipment, market, or risk profile.
Keep receiving inspection separate from the product definition. When goods arrive, use the bulk lash order inspection checklist to confirm identities, carton counts, sample selection, observable attributes, evidence, and disposition against the approved revision.
Control Changes, Substitutions, and Reorders
Add one direct rule: no change to an approved feature or component without documented buyer review. Cover fibers, finish, curl, strips, backing cards, trays, cases, printers, label data, and production method where these affect the agreed product. The supplier should identify a proposed change, affected SKUs, reason, timing, existing inventory, and whether a new sample is available.
A reorder should reference the last approved specification rather than “same as before.” Compare the new quote, SKU matrix, quantities, artwork revisions, shipping details, and any change notices with the archived order. If an approved component is unavailable, decide whether to resample, accept a documented change, or pause the SKU.
Maintain a retained sample or clear reference set when practical, but state its limitations and storage conditions. Aging, handling, photography, and environmental exposure can change how a reference looks or behaves.
Move From Spec to Quote, Sample, PO, and Reorder
- Create the draft: define the project, product families, SKU matrix, component codes, and open questions.
- Run a supplier feasibility review: ask the supplier to mark each field confirmed, unavailable, proposed alternative, or requiring clarification.
- Request a matched quotation: require the quote to reference the specification revision and show how MOQ is counted across products, packaging, and SKUs.
- Sample in stages: evaluate relevant stock samples, custom product samples, printed proofs, or an assembled approval sample as the project requires.
- Close every open field: update the specification, change log, artwork register, and approval record. Archive superseded files.
- Issue the purchase order: reference the approved specification and list every SKU, quantity, price, and accepted commercial term.
- Inspect and release: compare the received lot with the current reference using the agreed inspection plan.
- Reorder under change control: confirm revision, current quote, component availability, and any proposed change before repeating production.
MOQ, fees, availability, lead times, shipping terms, and production timing can change. Treat a public product page as research and a current written quote for the exact project as the commercial reference. To compare cost beyond the unit price, use the lash tray cost-per-set guide.

Common Specification Sheet Mistakes
- Using one vague product name: separate every sellable curl, diameter, length mix, fan dimension, or kit assortment into a controlled SKU.
- Letting chats become the master record: transfer accepted decisions into the dated revision and obtain acknowledgment.
- Approving packaging before the product: close the lash construction and assortment early enough to keep labels and barcodes accurate.
- Copying another brand's claims: require evidence and appropriate market review for your own product and wording.
- Writing subjective acceptance terms: define what “matte,” “wide,” “easy pickup,” or “consistent” will be compared against.
- Assuming the quote includes every component: match unit price, setup charges, packaging, freight basis, and MOQ logic to the same revision.
- Skipping change control on reorders: ask for written notice before an approved material, component, process, or file changes.
- Treating the sheet as proof: specifications state intent; sampling, documentation, inspection, and applicable review provide separate evidence.
Build a Product Brief With BOBOLASH
BOBOLASH's current wholesale and private-label page describes manufacturing, wholesale, and branded packaging options. Use it as an introduction, then request a current written quotation for your product family, SKU mix, packaging, destination, and approval needs.
Different products reveal why one generic specification is not enough. A handmade-volume brief can begin with the live 0.03mm Volume Lash Extensions and 0.07mm Volume Lash Extensions pages as catalog references, while a premade-fan brief needs fields like fan dimension, base profile, and bonding method. Verify current options and availability rather than copying a listing into an approved specification.
When your draft matrix and questions are ready, contact BOBOLASH and attach the revision you want reviewed. Ask the team to identify confirmed options, alternatives, open fields, sample stages, MOQ rules, and current commercial terms in writing.
Private Label Lash Specification Sheet FAQs
What is a private label lash specification sheet?
It is a revision-controlled document that defines the intended lash product, SKUs, construction, tray components, packaging references, approval evidence, acceptance criteria, and change rules. It helps a buyer and supplier discuss the same version during quotation, sampling, production, and reorder.
Is a lash specification sheet the same as a purchase order?
No. The specification defines the product, while the purchase order authorizes a particular commercial order. The PO should identify the exact approved specification revision as well as SKUs, quantities, price, delivery details, and other accepted terms.
Do I need a separate sheet for every lash SKU?
Use one master matrix for all SKUs and detailed blocks for fields that differ. Several SKUs can share approved components, but every sellable combination should have a unique identifier and an unambiguous curl, diameter or dimension, length plan, row or unit count, and packaging code.
Should I put MOQ and lead time in the specification?
Cross-reference them, but keep the current quotation as the commercial source. Record how MOQ is counted and which quote applies. MOQ, fees, availability, and lead-time assumptions may change with the SKU mix, packaging, quantity, timing, and destination.
How do I specify lash curl or finish?
Record the supplier's code and description, then connect them to an approved labeled sample and an agreed comparison method. Names alone are not enough because curl and finish terminology may vary among suppliers and product families.
Can an approved sample replace written specifications?
No. A sample may be the best reference for appearance or handling, but it can omit identity, dimensions, row sequences, component codes, artwork revisions, claims, and change rules. Use the physical reference and written specification together, with clear approval limits.
Does a specification sheet guarantee product quality or compliance?
No. It states the intended requirements. Supplier review, supporting documents, appropriate legal or regulatory assessment, controlled samples, production controls, and inspection address different questions. The applicable requirements depend on the product and sales market.
Final Checklist Before You Send the Sheet
Before submitting the document, confirm that every SKU is unique, every mixed tray has a row sequence, every product family has format-specific fields, every packaging component points to the correct artwork, every proposed claim has a review status, and every sample approval states exactly what it covers. Add a revision number, close or clearly label open questions, and ask the supplier to acknowledge the same version.
A well-built private label lash specification sheet does not make sourcing risk disappear. It makes the decisions visible, comparable, and easier to repeat—and gives the buyer, supplier, artwork team, and inspector a shared reference for the next step.
