Manufacture your product in China: from development to production
We turn an idea, reference or existing product into a manufacturing project: defining requirements, identifying the right manufacturer, coordinating samples and customisation, following production and managing quality, documentation and importing when required.

Your starting point
You do not need a fully developed product to begin
The process changes depending on the information you start from. We can work from a market reference or an initial specification and coordinate the stages required to reach a version suitable for production.
- 01
I have an idea
We start from functions, use, target market and available references to define what needs to be specified before looking for a manufacturing solution.
- 02
I have a reference product
We analyse what you want to keep, change or improve and look for manufacturing alternatives compatible with that objective.
- 03
I want to customise an existing product
We coordinate ODM or customisation options for the product, finishes, functions, accessories, packaging and branding, depending on what each manufacturing platform allows.
- 04
I already have a design, sample or specifications
We can move directly to manufacturer validation, quotation, samples, adjustments and production preparation.
Development model
OEM, ODM or customisation: not every project starts the same way
- 01
OEM
Manufacturing to your specifications
The product starts from requirements, design, specifications or developments defined for the project. The manufacturer produces according to the agreed scope.
- 02
ODM
Starting from an existing platform
A base already developed by the manufacturer is used and the available elements are customised: functions, finishes, accessories, packaging or branding, depending on the product.
- 03
Customisation / private label
Adapting an existing product
In simpler projects it may be enough to select an existing reference and customise commercial or presentation elements.
We do not push a particular model. The right option depends on the product, volume, budget, timeline and the level of differentiation you need.
From concept to factory
How we turn an idea into a manufacturable project
- 01
Brief and requirements
We define product, functions, known specifications, market, estimated volume, target cost, references and project constraints.
- 02
Manufacturing strategy
We determine whether it makes more sense to start from an existing product, an ODM platform or a more customised development.
- 03
Manufacturer selection
We identify manufacturers compatible with the product and the level of development required and compare capacity, terms and technical/commercial proposals.
See how we manage purchasing and manufacturers in China - 04
Samples and prototypes
We coordinate samples, prototypes or development versions and collect the adjustments needed before approving the product.
- 05
Moulds, manufacturing tools and production preparation
If the project requires moulds, manufacturing tools or other specific developments, we coordinate scope, cost, terms and validation before production.
- 06
Approval and production
With the reference approved, specifications, terms and relevant criteria are confirmed before production starts and is followed up.
- 07
Quality, documentation and importing
We coordinate the necessary inspections and reviews and, when it is part of the scope, documentation, freight, customs clearance and importing.
See product compliance and documentation

A sample is not a formality: it is the reference for production
One of the biggest risks when manufacturing a customised product is moving from an idea or quotation to a production order too soon. Samples turn expectations into a concrete reference before committing volume.
- 01Initial sample
- 02Customised sample
- 03Prototype
- 04Revised sample
- 05Approval or pre-production sample
Depending on the project some of these stages may apply, not necessarily all of them. The number of iterations depends on the product and on the distance between the first proposal and the expected result.
Does the product need its own moulds or manufacturing tools?
Some developments require moulds, manufacturing tools, specific parts or development costs before production. These items can represent a significant share of the initial investment and should be defined before committing to the project.
- Cost
- What exactly the amount covers and what payment terms are agreed.
- Ownership
- What the client and the factory agree regarding manufacturing tools developed for the project.
- Use
- Which products, references or projects those moulds or tools can be used for.
- Maintenance or replacement
- What responsibilities each party takes on where relevant.
Ownership and usage terms depend on the specific agreement with each manufacturer and should be reviewed before making any payment.

MOQ, unit cost and development cost are connected decisions
Manufacturing cost cannot be assessed per unit alone. Minimum quantity, samples, moulds and manufacturing tools, packaging, components, testing, freight and expected volume can significantly change a project's economics.
Upfront cost
- Samples
- Specific developments
- Moulds and manufacturing tools
- Testing where applicable
Recurring cost
- Manufacturing
- Packaging
- Inspection
- Logistics
- Importing
Define ownership before investing in development
Before funding moulds or manufacturing tools, it is worth agreeing in writing with the manufacturer who owns them, how they are identified, where they will be kept, permitted uses, maintenance, and return or transfer terms. Pre-existing factory elements are identified separately. A change of factory or subcontracting is subject to the applicable prior agreement.
Client
Specific development
Manufacturer
- Designs and documentation provided by the client
- Developments created specifically for the project
- Moulds and manufacturing tools
- Pre-existing factory components or platforms
- Packaging and graphic files
- Conditions for changing manufacturer if needed
The outcome depends on the actual agreement with the factory. Depending on the project, an NNN agreement may be considered with legal advice specialised in China; on its own it does not secure ownership or the return of the tools.
What was approved must be what reaches production
Once the sample or specification is approved, any later change can affect the product, price, lead time, documentation or quality. That is why it is important to keep a clear reference and control modifications during the project.
- 01Approved reference
- The validated sample or specification acts as the reference against which production is compared.
- 02Specifications and changes
- Changes agreed during the project are recorded so they are not lost between emails and conversations.
- 03Production follow-up
- We follow progress with the factory and the milestones agreed before shipment.
The destination market must be considered before manufacturing
A manufacturable product is not necessarily a product that can be sold in any market. Category, functions, materials, labelling, documentation and claims can change the applicable requirements.
That is why, where relevant, we coordinate the review of technical and documentary requirements during development and not only once the goods are already finished.
See product compliance and documentationRequirements depend on each product and market. EC HolaHome coordinates the process with manufacturers, laboratories and specialised professionals when necessary.

Already selected a factory?
There is no need to restart the project. We can join at its current stage and help you review terms, samples, specifications, development, production, quality, documentation or importing.
Review my projectFrequently asked questions about manufacturing a product in China
01Can I start if I only have an idea?
Yes, as long as we can define the need clearly enough to determine what kind of development and manufacturer the project requires. In some cases design or engineering specialists will also be needed.
02What is the difference between OEM and ODM?
Broadly speaking, OEM is used when manufacturing starts from specifications or developments defined for the project, while ODM starts from a platform or product previously developed by the manufacturer and allows certain levels of customisation. The actual scope depends on each factory and product.
03Do I need to make a mould?
Not necessarily. It depends on whether the product uses existing components and structures or needs specific parts. If moulds or manufacturing tools are required, their cost, ownership, use and terms must be defined before payment.
04How many samples are needed?
There is no universal number. It depends on product complexity, the level of customisation and the changes required to reach an approvable reference.
05Do you review certifications and requirements?
We coordinate the documentary review and the requirements applicable to the product and market together with manufacturers, laboratories and specialised professionals where relevant. EC HolaHome is not a laboratory or a certification body.
06Do you also manage importing?
Yes. When the full project is contracted we can coordinate freight, documentation, customs clearance and delivery. We can find a manufacturer or join the one you already work with.
