OEM, contract manufacturing and private label
The simplest difference is who owns the formula.
Private label starts from an existing product direction held by the manufacturer. You adapt it, put your brand on it, and the underlying formulation knowledge stays with the maker. It is the fastest route to market and the lowest development cost.
OEM and contract manufacturing start from your specification. You bring a formula, a specification sheet or a reference product, and the manufacturer produces against it. You carry the formulation, and usually the intellectual property with it.
Custom development starts with your brief and creates a new formula. Agree formula ownership in writing before development begins.
If you do not already have a formula or specification, private label or custom development is usually the better starting point.
What a workable specification contains
The single most common reason an OEM enquiry stalls is an incomplete specification. A brief that can be quoted and produced against generally covers:
- Full ingredient list with percentages, including the composition of compound ingredients such as coated seeds, candied fruit or preserves.
- INS numbers for every additive, particularly colours, humectants and preservatives. This applies inside compound ingredients too, which is where it is most often missed.
- Sensory targets: sweetness level, flavour intensity, piece size, texture and colour, described in a way someone can reproduce.
- Physical and shelf-life parameters: moisture, water activity if known, required shelf life and the storage conditions it must hold under.
- Allergen position, including whether tree nuts and sesame are acceptable and what cross-contact statement your market requires.
- Pack format and primary packaging material, with barrier requirements if the destination is humid.
- Destination market, which determines labelling, permitted additives and documentation.
If you hold some of this and not the rest, that is normal and workable. The gaps simply become part of the development conversation rather than a surprise at production.
Where reference products help
A physical sample of the product you want matched is worth more than several pages of description. Flavour language is subjective, and "lightly sweet, fennel-forward, not sticky" means different things to different people.
Send the reference with its pack and label intact where possible. The label carries the ingredient declaration, and the pack tells us about barrier and format decisions the original maker took. Both shorten the path to a first sample considerably.
How runs are quoted
MOQ, price and lead time depend on the product, pack, quantity and destination. We quote them after reviewing the brief, so both pilot and large production runs can be considered.
The sequence is simple: brief, feasibility review, samples, feedback, specification and formal quote. Product samples are free; you cover shipping.
Facility, certifications and documentation
Production runs from our own facility at Palwal, Haryana, in the Delhi NCR region, under FSSAI licence 10821014000051 held by Kabir Foods Pvt Ltd. Superseeds Marketing LLP is the marketing entity, with its registered office in Netaji Subhash Place, New Delhi. Both are Wellubia group companies, so product development and production sit under one roof rather than across a contracted relationship.
Certifications held are FSSAI, GMP, HACCP, Halal, ISO 22000, FSSC 22000, ZED and AYUSH. Which of these matters depends on your destination, and certificate scope and validity are shared against the specific brief rather than as a generic attachment. FSSC 22000 is the one most frequently specified by international retail buyers; Halal is a hard requirement across much of the export market.
Wellubia products are supplied to buyers in more than ten countries, and destination-market documentation is prepared for your market before shipment rather than assembled afterwards.
From pilot to production
A pilot blend may behave differently at production scale. Heavier seeds can settle while lighter coated pieces rise. Piece size, coating or blending method may need adjustment before the full run.
Raw materials may also vary slightly in colour, size and moisture at larger volumes. Set acceptable tolerance ranges in the specification.
Ask early whether what you are piloting can actually be run at your target volume. If the honest answer is that something will need to change, it is better to know while a recipe is still open.
Quality control and batch documentation
Agree what will be checked and recorded for every batch. This may include moisture, fill weight, flavour and appearance against the approved reference, foreign-matter checks and seal integrity.
Set measurable tolerances for colour, piece size, moisture and sweetness. Also agree what happens if a batch falls outside those limits.
Change control
Document every change after the specification is locked. Ingredient, supplier, packaging or process changes can affect the product, shelf life, allergens or label.
Require written notice for every specification change and your approval for any change that affects the label.
Intellectual property and confidentiality
Where you bring a formula, it remains yours. Where a formula is developed for your brief, ownership should be agreed in writing before development begins. This is straightforward to settle early and unpleasant to argue about once a product is selling, so raise it in the first commercial exchange rather than treating it as a legal formality for later.
Frequently asked questions
What is the difference between OEM and private label?
OEM and contract manufacturing start from a specification or formula the buyer owns. Private label starts from an existing product direction held by the manufacturer, which the buyer adapts and brands. OEM gives the buyer formulation ownership; private label gives faster time to market.
Do I need a complete formula to start an OEM conversation?
No, but the more complete the specification the faster it moves. Gaps become part of the development conversation. A physical reference product with its original label is often more useful than a partial written specification.
Who owns a formula developed by Wellubia for our brief?
That is a commercial matter to agree in writing before development starts. Where a buyer supplies an existing formula, it remains the buyer's.
What is the minimum order for a contract manufacturing run?
There is no fixed minimum. Quantity, pack and lead time are quoted against the specific brief, so pilot volumes and container-scale orders are both worth discussing.
Where is production located?
At our own facility in Palwal, Haryana, within the Delhi NCR region, under FSSAI licence 10821014000051.
Which certifications are held?
FSSAI, GMP, HACCP, Halal, ISO 22000, FSSC 22000, ZED and AYUSH. Scope and validity documentation are shared against the destination brief.
Will the pilot recipe be the production recipe?
Not always. Blends can segregate differently at scale, with heavier seeds settling and lighter coated pieces rising. Piece size, coating or blending method may need adjusting, so ask at the outset whether what you are piloting can be run at your target volume.
What batch documentation is provided?
Parameters checked and recorded per batch typically include moisture, weight and fill accuracy, sensory conformance against an agreed reference, foreign-matter checks and seal integrity. Retention of samples and access to testing are agreed as part of the specification.
How are specification changes handled?
No change to a locked specification without written notification, and no change affecting the label without the buyer's explicit approval. Ingredient substitutions and packaging material changes can affect shelf life or invalidate a label declaration, so they are documented rather than absorbed quietly.
