What Usually Goes Wrong for Marketplace Sellers

Four failures we see more often than a bad product.

A listing gets blocked before it gets sold

In Germany, France and Spain a marketplace listing is blocked without a packaging registration in that country. It is a registration, not a certificate, and it has to exist before you list — not after your first sale.

Cartons and labels are practical blockers, not legal ones

Marketplaces reject cartons that break their weight and size limits, and units without a scannable barcode label. Nothing is wrong with the product. It just never reaches the shelf.

The paperwork changes with the marketplace, not the product

An EU listing asks for the CE declaration, an EU Authorised Representative named on the listing and instructions for use in the marketplace language. Great Britain asks for UKCA and a UK Responsible Person instead. The US route is different again.

A stock-out costs you the rank you paid for

Your first order has to cover launch and the first restock. If the reorder has to restart development, the listing loses the position you paid to build.

What We Do About Each One

Four controls, all of them things we already run for other sellers.

01

Packed the way your inbound plan expects

Carton specification applied to your SKUs, barcode and FNSKU labels applied at the factory, and mixed-SKU cartons where your inbound plan needs them. Tell us at quotation stage so it is built into the order rather than added afterwards.

02

The document pack your marketplace actually asks for

CE or UKCA declaration by destination, packaging registration for DE / FR / ES, EU Authorised Representative and UK Responsible Person details, instructions for use in the marketplace language, MSDS, and a substantiation file for your listing wording.

03

A restock that does not restart development

Once your specification is approved we hold it. Mass production runs 7–15 days on 5 automated lines at 2M+ units a month, so a reorder is a production slot rather than a new project.

04

Start below the custom minimum

Put your artwork on a stock specification from 500 boxes. Move to 5,000 boxes with your own printed boxes, inserts and display units once the SKU has validated — the approved specification carries over.

Your Route

Most sellers start at the top and move down once the SKU proves itself.

Where most sellers start
Private label on a stock specification

Your artwork on an existing strip and pack, from 500 boxes. The fastest way to get a listing live with your own brand on it.

Once the SKU validates
Custom packaging

Printed boxes, inserts and counter display units, from 5,000 boxes. Tooling and artwork set-up need volume to spread across.

If you would rather not brand at all
Wholesale

Our stock range at tiered wholesale prices, mixed-SKU orders welcome. See the wholesale page for how that route works.

Not sure which one you are? Read the OEM and private label process, or compare the two routes on wholesale nasal strips. Supplying a pharmacy chain, buying as a distributor, or launching your own brand? Each buyer type has its own route under solutions.

The Pack for Your Marketplace

Four marketplaces, four genuinely different lists. Pick yours and request the matching set.

Two of the registrations named there are public and you can check them without asking us: the MHRA entry for Great Britain and our EUDAMED record as manufacturer. The United States is the exception — FDA publishes no public database for cosmetic facility registrations, so there we give you the FEI number and send the submission confirmation on request.

In Their Words

Send Us the Marketplace, Not Just the Product

Which marketplace, which country, which SKUs and roughly how many. That is enough for us to tell you the MOQ, the documents and the realistic route to a live listing.

Amazon and Marketplace FAQs

What sellers ask before a first private label order.

Can you apply barcode and FNSKU labels for me?
Yes. Send the FNSKU or EAN and we apply the labels at the factory and pack to the carton specification your inbound plan requires. It is an order-level option, so raise it at quotation stage rather than after production has started.
Do I really need a packaging registration before I list in Germany?
For Germany, France and Spain, yes — marketplace listings are blocked without a packaging registration in that country. It is a registration rather than a certificate, and it has to be in place before the listing goes live. The resource library lists what we hold for each of the three markets.
Is CE enough for Amazon UK?
No. Great Britain requires the UKCA declaration and a UK Responsible Person; CE is not accepted there, and Northern Ireland follows its own arrangement. Our UKCA declarations are issued per SKU rather than per company, and Class I devices have no notified body and no certificate — only the manufacturer declaration.
What does Amazon US need?
The cosmetic route under MoCRA: FDA cosmetic facility registration with the FEI number, a US agent, and MSDS. There is no CE in the US route. FDA publishes no public database for cosmetic facility registrations, so we give you the FEI number and send the submission confirmation on request.
Can I split a first order across several SKUs?
Yes. Mixed-SKU orders are welcome on both the wholesale and private label routes, and that is how most sellers test a range before committing to one SKU at 5,000 boxes.
How quickly can I restock?
Mass production runs 7–15 days after sample approval, and because your approved specification is held, a reorder is a production slot rather than a new development cycle. Transit then depends on the mode you choose — sea, air or express.
