NDA For Product Manufacturers: What To Include

Sharing your product design with a manufacturer can feel exciting and uncomfortable at the same time. You need quotes, feedback and maybe a prototype, but you also don't want your idea, drawings or supplier list passed around without control.

A well drafted NDA can give you a clear set of rules before you send CAD files, samples, specifications or tooling details to a factory. It won't solve every IP issue on its own, but it can make your position much stronger if something goes wrong.

If you're looking for an NDA for a manufacturer in the UK, the key is to make it practical for the way manufacturing actually works. That means thinking about samples, subcontractors, overseas factories, production runs and who owns improvements made along the way.

Do You Need An NDA Before Speaking To A Manufacturer?

Yes, you should usually put an NDA in place before you share confidential designs, prototypes, specifications or commercial information with a manufacturer.

An NDA, also called a confidentiality agreement, is a contract that tells the manufacturer what information is confidential, what they can use it for, and what they must not do with it. For product businesses, this can cover both technical information and business information, such as:

• CAD drawings, sketches, measurements and a clear product specification schedule.
• Prototype photos, videos, test results and sample units.
• Manufacturing methods, materials, formulations and component sources.
• Target pricing, margins, launch dates and customer information.
• Tooling designs, moulds, jigs and production processes.

Without a written agreement, you may still have some protection under the common law of confidence and the Trade Secrets (Enforcement, etc.) Regulations 2018. But in practice, it's much harder to prove what was confidential, what the factory was allowed to do with it, and what happens if they disclose it to someone else.

An NDA is especially helpful at the early discussion stage, when you may not yet have a manufacturing agreement, product supply agreement or purchase order in place. It sets the ground rules before the commercial relationship becomes more detailed.

For example, Mia is developing a reusable kitchen product and wants quotes from three factories. Before she sends her CAD files and prototype photos, she asks each factory to sign a one-way NDA. That way, each factory can review the product only for quoting, prototyping and discussing possible production with Mia, not for making a similar product for another customer.

What Should A Manufacturing Confidentiality Agreement Cover?

A manufacturing confidentiality agreement should clearly cover the information you're sharing, the limited purpose for using it, and the practical restrictions the manufacturer must follow.

A vague NDA that simply says confidential information must be kept secret may not go far enough for product development. You want the agreement to match the reality of manufacturing discussions, where files might be sent to engineers, sourcing staff, tooling makers and quality control teams.

A strong manufacturer NDA will usually deal with:

• The parties: Name your business correctly, including the company name and company number if you trade through a company registered at Companies House.
• The purpose: Limit the manufacturer's use of your information to assessing, quoting, prototyping or manufacturing your product for your business.
• What is confidential: Include written, oral, visual, physical and electronic information, not just documents marked confidential.
• Non-use: Stop the manufacturer from using your information to make competing products or help another customer.
• Non-disclosure: Stop the manufacturer from sharing information except with approved people who need to know.
• Security: Require reasonable steps to protect your files, samples and product details from unauthorised access.
• Return or destruction: Set out what happens to files, samples, drawings and copies if discussions end.
• Duration: State how long confidentiality lasts. Trade secrets may need protection for as long as they remain secret.

You should also think about whether the NDA is one-way or mutual. If only you're sharing confidential information, a one-way NDA is usually enough. If the manufacturer is sharing its own confidential pricing models, production methods or supplier details, a mutual NDA may be fairer.

The agreement should also say which law applies. If your business is based in England or Wales, you may want English law and the courts of England and Wales to apply. If the manufacturer is overseas, this becomes more sensitive, because enforcing the agreement abroad may involve local rules and practical costs.

How Do You Protect Prototypes, Samples And Tooling?

You protect prototypes, samples and tooling by treating them as confidential property and spelling out exactly what the manufacturer can and can't do with them.

This is where many basic NDAs fall short. Product manufacturers don't just receive information. They may receive physical samples, access to testing units, 3D printed prototypes, packaging mock-ups, mould designs, dies or jigs. If your NDA only talks about documents, you may leave gaps.

Prototypes And Samples

Your NDA should say that prototypes, samples and physical product units are confidential, even if they don't have confidential labels on them. It should also restrict reverse engineering, copying, photographing, measuring or testing them except for the agreed purpose.

For example, if you send a sample unit so the factory can estimate the tooling cost, they shouldn't be allowed to pull it apart and use the design for a different client or their own product range.

Tooling, Moulds And Production Assets

Tooling can be one of the most valuable parts of your manufacturing setup. If you pay for a mould, die or jig, your documents should say who owns it, who can use it, where it will be stored and what happens when the relationship ends.

Say Noah pays a factory GBP 4,500 to create a mould for a silicone pet product. The NDA and later manufacturing agreement say the mould can only be used to manufacture Noah's products, the factory can't use it for other customers, and the mould must be returned or transferred to another factory if Noah changes suppliers. That gives Noah a much clearer position than simply paying the invoice and hoping the factory does the right thing.

Your NDA can also require the manufacturer to label and separate your samples or tooling from other customers' materials. For higher-value products, you might also ask for an inventory of samples and production assets held by the factory.

What If The Factory Uses Subcontractors Or Is Overseas?

If the factory uses subcontractors or is overseas, your NDA should control who can access your information and make the manufacturer responsible for those people.

Manufacturing often involves more than one business. A factory might outsource tooling, packaging, electronics assembly, finishing, testing or logistics. That can be perfectly normal, but you don't want your design moving through a supply chain without rules.

Your NDA should say the manufacturer can't disclose your confidential information to subcontractors, affiliates or agents unless:

• You have approved the disclosure in writing, or the NDA clearly permits it for defined production activities.
• The recipient genuinely needs the information for the agreed purpose.
• The recipient is bound by confidentiality obligations at least as strict as the NDA.
• The manufacturer remains responsible for any breach by that recipient.

For overseas factories, you should also think about language, governing law, and how realistic enforcement would be. An English law NDA is useful, but if the manufacturer and its assets are overseas, you may need local advice or extra controls, such as staged disclosure, watermarked files, limited access to full specifications, import and export controls, or separating critical components between suppliers.

You should also check whether you're sharing personal data. For example, if you send customer details, staff contact lists or order data to a manufacturer or fulfilment partner, UK GDPR and the Data Protection Act 2018 may apply. In that case, you may need data processing terms as well as confidentiality terms, especially if the overseas recipient will process personal data outside the UK.

A practical approach is to only share what the manufacturer genuinely needs at each stage. For an initial quote, they may not need your full supplier list, exact launch plan or full customer data.

Can An NDA Protect Your Product Idea And IP?

An NDA can help protect your confidential product idea, but it doesn't replace proper intellectual property protection.

In the UK, different parts of your product may be protected in different ways. Copyright under the Copyright, Designs and Patents Act 1988 can protect original drawings, written materials and certain creative works. Design rights may protect the shape or appearance of a product. Patents can protect some inventions, but only if they meet the legal tests, including novelty and inventive step. Trade marks protect your brand name or logo.

The UK Intellectual Property Office handles applications for patents, registered designs and trade marks. If your product may be patentable, be especially careful about disclosure. Publicly disclosing an invention before filing a patent application can damage your ability to get patent protection. Sharing under a properly drafted NDA can help preserve confidentiality, but you should get IP advice early if patent protection is on the table.

Your NDA should also deal with improvements and feedback. Manufacturers often suggest changes to materials, dimensions, packaging or assembly. That can be valuable, but it can also create confusion about who owns the updated design.

Consider clauses that say:

• Your existing designs, specifications and IP remain yours.
• The manufacturer receives no licence except the limited right to use your information for the agreed purpose.
• Any improvements, modifications or derivative designs created from your confidential information belong to you, or are assigned to you where legally possible.
• The manufacturer won't register trade marks, designs, domain names or other rights that are similar to your product or brand.

If the manufacturer is contributing significant design work, the position may be more complicated. In that case, you may need a product development agreement, manufacturing agreement or supplier agreement as well as an NDA, so ownership, fees and responsibilities are clear.

NDA For Manufacturer Template: What To Include

A template can be a helpful starting point, but a lawyer should tailor it before you use it with a manufacturer, especially if you're sharing prototypes, tooling or overseas production details.

Here is a practical fill-in outline for a product development NDA in the UK. This isn't a finished legal document, but it shows the main clauses to think about.

1. Parties: Insert your correct legal name and the manufacturer's correct legal name, including company numbers and addresses where available.
2. Background: Briefly describe the product discussion, such as quoting, prototyping, tooling, sampling or manufacturing.
3. Purpose: State the only reason the manufacturer can use your confidential information.
4. Confidential information: Cover designs, CAD files, samples, prototypes, tooling details, specifications, pricing, supplier details and business plans.
5. Physical materials: Say prototypes, samples, moulds, dies, jigs and product units remain your property unless agreed otherwise.
6. Non-use obligations: Stop the manufacturer from copying, reverse engineering, producing or commercialising your product outside the agreed purpose.
7. Non-disclosure obligations: Restrict disclosure to staff, contractors and subcontractors who need access and are bound by confidentiality.
8. Subcontractors: Require your approval or clear conditions before your information is shared down the supply chain.
9. IP ownership: Confirm your existing IP stays with you and deal with improvements or modifications.
10. Security and access: Require sensible protection of electronic files, drawings, samples and tooling.
11. Return or destruction: Set out what must happen to your information and materials when discussions end or you ask for them back.
12. Duration: Choose a period that suits the information. Some commercial information may expire, but trade secrets may need ongoing protection.
13. Exclusions: Carve out information that's already public, already known by the recipient, or lawfully received from someone else.
14. Remedies: Say you can seek urgent protection if confidentiality is breached, as money alone may not fix misuse of a product design.
15. Governing law: Choose the law and forum for disputes, taking extra care for overseas manufacturers.

Once the NDA is signed, don't treat it as a filing exercise. Keep a record of what you share, when you share it and with whom. Watermark files, label confidential documents and use version control for design changes. These habits make it easier to prove what happened if there's a dispute later.

Key Takeaways

• Use an NDA before you send designs, prototypes, samples, CAD files or tooling details to a manufacturer.
• Your NDA should cover physical items as well as documents, including samples, moulds, jigs and product units.
• Subcontractors matter. If a factory may outsource work, make sure your NDA controls onward disclosure and makes the factory responsible.
• An NDA helps protect confidentiality, but patents, registered designs, copyright and trade marks may need separate IP protection.
• For overseas manufacturing, think about staged disclosure, governing law, local enforceability and practical controls over your files and samples.
• Templates often miss manufacturing-specific details, so have your NDA tailored to your product and supply chain before you rely on it.
