Lash Supplier Change Notice: 7 Critical Reorder Checks

Lash Supplier Change Notice Buyer Summary

A lash supplier change notice should identify the affected SKU, previous approved reference, proposed change, reason, effective batch, expected impact, and required quote, sample, proof, or buyer re-approval before the reorder enters production.

Supplier Product Change Notice Buyer Summary

A supplier product change notice should identify the affected lash SKU, previous approved reference, proposed change, reason, effective batch, expected impact, and required quote, sample, proof, or buyer re-approval before the reorder enters production.

Direct Answer

A lash supplier change notice should reach the buyer before implementing any material, specification, process, packaging, label, or source change that could alter the approved product or its reorder traceability. The notice should identify the affected SKU, previous approved reference, proposed change, reason, effective batch, expected impact, and whether a new sample, quote, proof, or buyer approval is required.

A repeat purchase order is not permission to silently change the product. Reorders normally depend on the buyer receiving the same controlled specification, or receiving enough information to approve a documented change before production.

Supplier Change Notice vs Buyer Change Request

These are different controls:

• A buyer change request starts when the buyer asks to change a curl, quantity, packaging design, destination, or other order field.
• A supplier product change notice starts when the supplier proposes or must disclose a change to material, process, equipment, source, specification, packaging, label, or production location.

The buyer should not learn about a supplier-originated change from the finished batch or carton label.

Changes That Should Trigger a Notice

Change category	Example in a lash reorder	Typical buyer action
Product specification	Curl calibration, thickness tolerance, length map, finish	Review impact and retest when product performance may change
Material or component	Fiber, strip, adhesive base, tray, paper card, box material	Compare against approved reference and assess sample need
Production process	New forming, cutting, curing, strip-setting, or inspection method	Request evidence or a validation sample when output can change
Packaging or artwork	Tray card, logo position, unit box, barcode, carton mark	Review a new proof before printing or packing
Supplier or source	New material source, subcontractor, packaging vendor, or production site	Review traceability and quality risk
Administrative record	Contact name or internal document format with no product impact	Record update; product re-approval may not be necessary

What a Useful Change Notice Contains

A usable supplier change notification should include:

1. affected product and SKU;
2. previous approved sample, specification, and packaging version;
3. precise description of the old and new condition;
4. reason for the change;
5. affected material, process, source, label, or document;
6. expected effect on performance, appearance, packaging, lead time, price, or traceability;
7. first proposed production batch and effective date;
8. available comparison evidence;
9. recommended validation path;
10. named supplier owner and buyer approval status.

The general quality-system principle is simple: changes should be controlled, dated, authorized, and traceable. The ISO auditing guidance on digital processes and change control supports that documentation logic. It is referenced as a general process principle, not as a claim that a lash order is governed by a specific ISO certification.

Change Impact and Approval Matrix

Impact level	Example	Quote update	Sample or proof	Buyer approval
Administrative only	Contact or internal form layout	Usually no	No	Record acknowledgement
Commercial only	Price, MOQ, lead time, or shipping scope	Yes	Usually no	Yes before PO revision
Packaging or label	Box material, logo position, barcode, carton mark	Maybe	New proof	Yes before printing
Product performance	Fiber, curl, thickness, strip, finish, length map	Maybe	Retest or new sample	Yes before production
Source or process risk	New vendor, process, equipment, or production site	Maybe	Risk-based comparison	Yes before affected batch

This matrix is a starting point. The buyer and supplier should decide based on the actual effect, not only the supplier's label for the change.

When a New Sample Is Necessary

Retest when the change can affect curl retention, thickness, softness, finish, strip release, lash removal, mapping, tray alignment, or other buyer-approved performance. A sample is also useful when the new source or process does not have enough comparable production history.

Use the LASHMAITRE sample process to define what is tested and what approval code becomes the new reference.

When a New Packaging Proof Is Necessary

Require a new proof when the change touches the tray card, box dieline, paper stock, finish, logo position, text, barcode, carton mark, label size, or print method. The proof should show a version number and replace, not merely sit beside, the old production reference.

For private label orders, the private label lash extension page shows why packaging proofs and production files must stay tied to the approved SKU.

Do Not Approve the Reorder Until the Effective Batch Is Clear

The change notice should state whether the next reorder uses the old condition, the new condition, or a transition lot. Record the first affected batch ID and confirm how old and new inventory will be separated. If a supplier cannot identify the effective batch, the buyer cannot reliably inspect or investigate the change later.

Lash Supplier Change Notice FAQ

Which supplier changes require buyer notification?

Notify the buyer about changes that may affect product specification, performance, appearance, packaging, labels, traceability, price, lead time, or the approved production source.

Does every supplier change require a new lash sample?

No. Administrative changes may only need a record update. Product, material, process, or source changes should be assessed for retesting based on their possible effect.

Can the supplier implement a packaging change before approval?

Not when the packaging is part of the approved private label scope. The buyer should review the revised proof and its commercial or timing impact before production.

What should happen to the old approved sample?

Keep its reference in the change record. Mark whether it remains valid, is superseded, or applies only to earlier batches.

How should a change be handled during an active reorder?

Place the affected scope on hold, identify the effective batch, assess quote and schedule impact, complete required sample or proof review, and obtain documented approval before continuing.

Control the Change Before the Reorder

Use the MOQ 50 planning page when a limited validation batch is the safest way to test a proposed change.

Review the LASHMAITRE lash quality-control process and ask the supplier to reference the affected SKU, previous approved sample, proposed change, effective batch, and validation plan before authorizing the reorder.

Send the supplier notice, affected SKU, previous approval code, and proposed validation plan through the wholesale lash inquiry page when a documented review is needed before the next production batch.
