The Food OEM Manufacturing Process: 6 Steps From Concept to Shelf
Updated: Oct 13
The food OEM process typically runs in eight steps: set the brief, choose the recipe, taste and sign off samples, design the packaging and labels, run production, check quality and traceability, deliver, then launch and reorder. Knowing the sequence lets a first-time brand prepare the right information at each stage.
First-time brand owners usually start with flavour and packaging. What decides how smoothly a product reaches the shelf is everything in between: who supplies the recipe, how samples are approved, what the label must say and how the goods travel. See the whole process and every conversation with a manufacturer becomes sharper.
Couverture by Multizen runs its own factory in Tsuen Wan, Hong Kong, and has more than 30 years of food manufacturing experience. What follows is general industry practice, with notes on how we handle each step.
We take the eight steps in order, then compare buyer types and finish with a short glossary.
Step 1: Set the Brief and Your Goals
What happens at this stage
Every OEM project starts with a clear brief. The brand explains what the product is, who it is for, where it will be sold and what customers should remember. The more specific the brief, the closer the first samples will be to what you have in mind.
A first meeting usually covers the product category, the target retail price range, sales channels, expected volume and launch timing. None of it needs to be final; a clear direction is enough to begin.
What to prepare before your first meeting
Product idea: chocolate, cookies, palmiers or mooncakes, plus any reference products or flavour direction
Target customer: age group and occasion, whether for self-purchase, gifting or souvenirs
Sales channels: your own shops, online store, supermarkets, hotels or corporate orders
Expected volume: a rough figure for the first batch, and whether you plan to reorder
Launch timing: the festival, opening or event you are working towards
Brand assets: logo, brand colours, typefaces and any existing packaging
Ingredient requirements: any preferred chocolate or ingredients, and allergens to avoid
Markets: Hong Kong only, or also the Mainland or overseas
Who does what
The brand brings the idea, the target customer and the commercial picture. The factory recommends suitable formats and explains the sequence. At Couverture, minimum order quantities are flexible and can be discussed around each brand's situation.
If you are still comparing manufacturers, our guide to choosing a food OEM manufacturing partner sets out the three keys to look for.
Documents from this step
The brief is typically written up as a short requirements summary, the basis for the quotation and first samples. For an unannounced product, both sides may sign a non-disclosure agreement first.
Step 2: Choose the Recipe and Develop Samples
Existing recipe or new development
The first big decision is whether to start from one of the factory's existing recipes or develop a new one. An existing recipe is already proven in production; the brand adjusts flavour, shape or decoration and adds its own packaging. New development builds a recipe around the brief, which suits brands that want a signature product.
Neither route is better in itself. To launch soon and test the market, an existing recipe is the natural start; if a distinctive flavour is central to your brand, development is worth it. Couverture's recipes have earned Monde Selection 2026 gold, so many brands taste our current range first and decide from there. For the basics of chocolate manufacturing, read our beginner's guide to chocolate OEM manufacturing, or see our chocolate OEM service.
OEM and ODM explained
Producing to a recipe developed around the brand's requirements is OEM. Selling the factory's existing recipe or design under your own name is usually called ODM. The two often combine, with an existing recipe adjusted to the brief. Couverture offers both.
How samples are made
Once the direction is agreed, the factory produces samples, the reference for full production, so the brand can check taste, texture, shape and colour. If the product will carry a logo, such as printed cookies or chocolate gold coins, the sampling stage also tests how sharp the artwork looks and how well the colours reproduce.
Expect more than one round: the first sets direction, later rounds refine it. There is no fixed count; it depends on the product.
What the brand provides
Flavour direction and reference products
Logo and artwork files, if the product itself will be printed
Any special ingredient requirements
Allergens that must be avoided
Keeping it moving
After each tasting, put your feedback in writing. "Slightly less sweet" or "a crisper outer layer" is far easier to act on than "make it taste better". Keep the same people on your tasting panel so feedback stays consistent.
Step 3: Taste, Refine and Sign Off
How to taste accurately
Tasting is about more than flavour. Judge the sample as it will be sold: in its intended packaging, after realistic storage, with people who represent your customers. A hotel might ask its pastry team to taste; a retail brand might ask its frontline staff.
What to assess
Flavour and texture: does it fit the positioning, and are sweetness, aroma and mouthfeel in balance?
Appearance: are the shape, colour and any printed artwork clear and consistent?
Size and format: does it suit the packaging design and the retail price?
Keeping quality: does it hold its condition under the expected storage and delivery conditions?
Cost: after any recipe changes, does the quotation still support your pricing?
Sign-off
When the brand is happy with the final round, it formally approves the sample. With the recipe specification, it becomes the production standard for every future batch.
Check every detail once more before you sign off. Changing the recipe after approval usually means a new sample round, so this is the step to take your time over.
Documents from this step
Typically the approved sample record, the product specification and a formal quotation.
Step 4: Packaging Design, Artwork Approval and Labelling
Packaging design
Packaging is the first thing your customer touches. Brands can supply their own design or use Couverture's end-to-end service, which runs from recipe development and production to packaging design.
Good packaging balances fit in the box, protection in transit and display. A retail product must be recognised at a glance; a corporate gift must feel right when opened.
Choosing packaging materials
Chocolate needs protection from heat and moisture; cookies and palmiers need a good moisture seal to stay crisp. Gift boxes can be paper, tins or drawer-style designs. Decide display and gifting needs first, then materials and finishes.
Artwork approval and colour proofing
The brand checks wording, logo position, colours and proportions, and printed items are proofed so the finished colour matches the design.
Have one person consolidate comments and confirm the final version in writing.
What the label must show
Prepacked food sold in Hong Kong generally has to meet local food labelling law. The information commonly required includes:
The name of the food
A list of ingredients, with allergens declared
A "best before" or "use by" date
Any special storage conditions or instructions for use
The net quantity
The name and address of the manufacturer or packer
Nutrition labelling, unless the product is exempt
Couverture labels its products bilingually in English and Chinese. For exact requirements, always refer to the latest guidance from the Centre for Food Safety. If the product will be sold on the Mainland or overseas, the label also needs to be checked against local rules there.
The M Mark label
Couverture takes part in the M Mark Quality Label Sharing Programme. Where a product is eligible, whether to carry the M Mark can be discussed during packaging design, giving customers an easy way to recognise quality.
Step 5: Pre-Production Checks and the Production Run
What to confirm before production
Before the production run, both sides typically go through one final check:
The recipe and specification match the approved sample
All packaging materials are in place, and print colours have been proofed
Label content has been approved
Quantities, batch split and delivery addresses are clear
It ensures the line starts on the right version.
The basic production stages
Raw materials are inspected on arrival and only released to production once they pass. Production then follows the approved recipe and process: mixing, shaping and baking for cookies, for example, or tempering, moulding and cooling for chocolate.
Couverture produces in its own factory in Tsuen Wan. The factory is certified to FSSC 22000 Version 6 by SGS, with a scope covering the manufacturing of bakery products (mooncakes, cookies, shortcakes and frozen cakes), the manufacturing of plain and mixed chocolate confectionery, and the repacking of chocolate confectionery.
Checking the first batch
It is good practice to compare the first batch against the approved sample before releasing the full shipment. Set out any acceptance criteria of your own before production.
Step 6: Quality Checks, Batch Records and SAP Traceability
Quality checks on the line
Quality control runs from incoming materials through key production points to finished goods and packaging. In general, a food safety management system analyses hazards at each stage, sets critical control points and defines how each is monitored and recorded.
Why batch records matter
Every batch number links to its raw materials, production date, process records and inspection results, so any batch can be looked into quickly.
SAP full-batch traceability
Couverture tracks every batch through SAP, from raw materials to finished goods, giving buyers a documented origin for every product.
Quality documents you can request
In general, brands can request the following for their records or a retailer's review:
A copy of the food safety certificate, checking the certified scope it lists
A product specification sheet covering ingredients, allergens and storage conditions
A batch record summary for checking by batch later on
What the certification means
FSSC 22000 is built on ISO 22000:2018 and ISO/TS 22002-1:2009, plus additional scheme requirements, and is recognised by the Global Food Safety Initiative (GFSI). Couverture's certificate is valid from August 2026 to August 2029, with regular surveillance audits throughout.
As General Manager Pat Cheng puts it: "Attaining the FSSC 22000 certification is a monumental milestone for Multizen Asia Limited. This achievement reflects the dedication of our entire team to upholding the highest benchmarks of food safety, strict quality control, and operational excellence."
Step 7: Packing, Temperature-Controlled Delivery and Logistics
Packing and cartons
Finished goods are packed in the approved packaging and cartons, usually marked with product name, batch number and quantity for easy stock control.
Temperature-controlled delivery
Chocolate is sensitive to temperature, and cookies and palmiers need to stay dry and crisp. Couverture offers temperature-controlled delivery, so products arrive at your warehouse or shop in the condition they left the factory. Tell the factory how goods will be stored on arrival.
Delivery arrangements
The brand provides delivery addresses, receiving hours and a contact person. List multiple shops, hotels or venues before production. If corporate gifts go directly to recipients, raise it early.
Shipping to the Mainland: CEPA
Under the Mainland and Hong Kong Closer Economic Partnership Arrangement (CEPA), food made in Hong Kong can enter the Mainland tariff-free. Typically, products must meet the rules of origin with the right certification and comply with Mainland labelling and import requirements. If you plan to sell on the Mainland, mention it in Step 1, so the recipe and label are planned for it from the start.
Step 8: Launch and Repeat Orders
Launch planning checklist
Check quantities, batch numbers and best-before dates on arrival
Plan display and stock space for shops, online orders or events
Prepare product photography, descriptions and price tags
Brief frontline staff on flavours, ingredients and allergen information
Hold back stock for replenishment
Track sales data to guide your reorder
Forecasting and reordering
After launch, your sales data is the best guide. Track each flavour by channel, then agree reorder quantities.
With everything already approved, reorders mainly confirm quantities, batches and delivery. A new pack or flavour simply revisits the relevant steps.
Planning for peak seasons
Chinese New Year, Mid-Autumn and Christmas are peak seasons for food gifts, and both production slots and packaging materials are in high demand. If a new product is meant to launch for a festival, we recommend enquiring at least two months ahead, leaving room for tasting, design and approvals.
For mooncakes and other seasonal products, review as soon as the season ends: best flavour, fastest-selling box, strongest channel.
Growing the range step by step
A common approach is to start with one product and extend flavours or ranges as the market responds, for example moving from chocolate into cookie or palmier gift boxes. Couverture makes chocolate, cookies, palmiers and mooncakes in the same factory, so brands can grow their range with a single manufacturing partner.
Retail Brands, Corporate Gifts and Hotels: How the Process Differs
The eight steps apply to every buyer, but the emphasis shifts.
Retail brands
The priorities are batch-to-batch consistency, shelf presence and fully compliant labels. Retailers typically ask for barcodes, and frequent reorders make forecasting key.
For example, a new online chocolate brand might test the market with a few existing flavours in its own packaging, then develop a signature flavour.
Corporate gift buyers
Corporate buyers work towards a fixed date such as an anniversary or year-end dinner. The focus is logo presentation, printed on cookies or chocolate gold coins, with boxes in corporate colours. Orders are often one-off with many delivery addresses, so confirm design and quantity early.
For example, a listed company ordering anniversary gift boxes might choose logo-printed cookies alongside Chocolate Neapolitans, and list the number of recipients and delivery addresses in Step 1.
Hotels and F&B groups
Five-star hotels and premium F&B groups want products in their own style, for welcome amenities, petits fours or hotel shop gift boxes. Pastry teams usually join the tasting.
One hotel may need two kinds of product: retail gift boxes sold under the hotel's name, which need full retail labelling, and products for internal hospitality, where consistent portions and reliable supply matter most. It helps to set these out separately in Step 1.
Overseas importers
Check the destination's label language, ingredient and import rules, and documents such as a certificate of origin. Name target markets in Step 1.
