Who Owns the Formula in Third-Party Manufacturing: IP and NDA Guide

Who owns the formula depends on where it came from. A formula you supply is yours, a manufacturer's ready or private-label formula stays theirs and is licensed to you for your brand, and a co-developed formula belongs to whoever your written agreement says it does. If the paper is silent, you are relying on assumptions, and assumptions are what end badly.

This guide walks through the three cases, what to put in an NDA, what to demand in writing before you share anything, and what you can realistically carry to another manufacturer later. It is general information, not legal advice. Ownership and confidentiality rules differ by country, so check current rules with your legal adviser before you sign. The wider process is covered in the complete guide to third-party cosmetic manufacturing in India.

Case 1: you supply the formula

If you bring a formula you developed, bought from a formulator, or inherited from a previous maker, the formula is yours. The manufacturer's job is to make it, not to learn from it.

That sounds simple, but three details decide whether it holds in practice:

• Proof of origin. Keep dated records showing where the formula came from: the formulator's invoice, the email that delivered it, the version history. If a dispute arises, "I own it" needs a paper trail.
• Your formulator's terms. If a freelance chemist wrote the formula, check that you were assigned the rights and not just given a copy. A formula you cannot legally pass on is not really yours.
• Manufacturer adjustments. Plants often need to tweak a formula to suit their equipment, such as mixing order, temperatures or a swapped emulsifier grade. Decide in advance who owns those process changes. A common and fair position is that the formula stays yours while the plant's general know-how stays theirs.

Case 2: you buy a ready or private-label formula

A ready formula is a base the manufacturer developed and already makes for several brands. You are buying finished product with your label on it, not buying the recipe. The formula remains the manufacturer's property, and you receive the right to sell products made from it under your brand.

That has clear consequences. You normally cannot demand the full formula, and you cannot assume exclusivity. Other brands may sell something very close to yours. If differentiation matters, there are three honest routes: ask for light customisation (fragrance, colour, a few actives), negotiate paid exclusivity for a defined period or territory, or move to a custom formula. The difference between these models is laid out in private label vs white label vs OEM vs ODM.

What you should still ask for in writing: the full ingredient list for labelling, the right to keep buying the same formula without silent changes, and notice before any ingredient is altered or discontinued.

Case 3: the formula is co-developed

This is where most disputes start. You bring a brief and some direction, the manufacturer's chemists bring the technical work, and several rounds later there is a formula nobody clearly owns. Do not leave this to goodwill.

Settle these questions before development starts:

1. Who owns the final formula, and does that change if you stop buying?
2. If the manufacturer owns it, are you licensed to make it elsewhere, and under what conditions?
3. If you own it, can the manufacturer reuse its base technology or its general method in other products?
4. Who owns the development data: trial batches, stability results, test reports?
5. What happens to the formula if either side closes or is acquired?

Custom development is usually charged separately from production. If you pay for development in full, that is a strong argument for ownership or a long exclusive licence. Put the reasoning in the agreement, not just the conclusion. The typical clauses are covered in key terms in a cosmetics contract manufacturing agreement.

Getting the NDA right

An NDA protects what you disclose before and during the project. A weak one is a form with a signature. A useful one is specific.

• Define what counts as confidential. Formulas, ingredient lists, supplier names, launch dates, product concepts, artwork, volumes and pricing. Mark documents "confidential" as well, because clarity helps later.
• Limit who sees it. The agreement should bind the manufacturer's staff, consultants and any subcontractor who touches your project, not only the company name on the letterhead.
• Restrict use, not just disclosure. The manufacturer must not use your information for any purpose other than making your product. This is the clause people forget.
• Set a duration. Formulas can stay secret for years, so a short expiry is a poor fit. Many NDAs run for a fixed period but keep trade secrets protected as long as they remain secret. Ask your adviser what suits your country.
• Cover return and destruction. When the relationship ends, your files, samples and trial records should be returned or destroyed, with confirmation.
• Name the governing law and the place disputes are settled. An NDA you cannot realistically enforce protects less than it appears to.

An NDA does not stop a manufacturer from making a similar product from its own general knowledge. Ask directly how the plant separates one client's work from another's: who has access to your files, how formulas are stored, and whether batch sheets for your product are visible to production staff who do not need them.

Exclusivity and non-compete: ask, and expect to give something

Exclusivity means the manufacturer will not make the same or a near-identical product for anyone else. A manufacturer weighing a 500-unit order will rarely give this free. Common trade-offs include a minimum annual volume, a development fee, or a time limit.

Define it narrowly. "No identical formula for another brand in this category for two years" is workable. "No similar products ever" is not, and a reasonable plant will refuse it. Remember the reverse direction too: a clause that stops you buying a similar product elsewhere can trap you.

Protecting your brand name, artwork and packaging design

The formula is only one asset. Your name, logo, label artwork, packaging design and any custom moulds or tooling are separate and often more valuable to a brand.

• Register your trademark in your own name in the markets you sell in before you share the name widely. Do not let the manufacturer or a designer register it on your behalf.
• Get a written assignment from any freelance designer for logo and label artwork.
• State that artwork files and approved print proofs belong to you and may be used only for your orders.
• For custom bottles, tubes or moulds, record who paid for the tooling, who owns it, where it is stored, and what happens to it if you leave. Packaging responsibilities are broken down in who sources what in third-party manufacturing.

What you can and cannot take to another manufacturer

This is the practical test of everything above.

• You can take: a formula you own, your brand name, your artwork, your customer list, and the specifications and test results you paid for and own under the agreement.
• You cannot take: a ready formula the manufacturer owns, its internal batch records and process know-how, or anything the agreement marks as theirs.
• It depends: co-developed formulas, development data, and tooling. These follow the paper, so make the paper clear on day one.

Even when you own the formula, moving it takes work, because a recipe on paper does not reproduce itself on different equipment. The mechanics are in switching manufacturers and technology transfer. Ask now whether the manufacturer will hand over the full formula with percentages on request, and in what time frame, because some will only release it under certain conditions.

A written checklist before you disclose anything

• Signed NDA covering use restrictions, staff and subcontractors.
• A clear statement of which of the three cases applies to each product.
• Ownership of development data, trial batches and test reports.
• Exclusivity terms, if any, with scope, duration and volume conditions.
• Rules on formula changes, with your approval required.
• Return or destruction of your materials at the end.
• Ownership and storage of artwork, packaging designs and tooling.
• What you can take with you if the relationship ends.

Harrods Health offers both ready formulas and custom formulation, and whichever route you take, ask for the ownership position in writing before work starts. Details on both routes are on the ready-to-market and custom formulation pages. Whoever you work with, a manufacturer that answers these questions plainly and early is showing you how it will behave when something goes wrong. One that dodges them is a warning worth noting among the red flags when vetting contract manufacturers.
