What to Prepare Before Starting an OEM / ODM Project
Project Checklist · 11 min read · Published 2026-08-27 · Updated 2026-10-02
Prepare your product idea, ingredients, preferred format, target market, packaging and estimated quantity for an OEM / ODM discussion. A finished formula is not required to begin.

Use this checklist to prepare your first manufacturer discussion. For the development and production steps, explore OEM / ODM services.
What does a useful supplement project brief contain?
A useful supplement project brief is a short decision record: what the product is intended to be, who it is for, how it may be used, where it may be sold and what is still undecided. It is not a regulatory submission, a manufacturing record or a final RFQ. The first version should be clear enough to guide questions, but flexible enough to change after feasibility review.
For a U.S.-market dietary supplement, the relationship between product identity, contents, ingredients and the responsible business appears directly in the label framework. The FDA lists a statement of identity, net quantity, nutrition labeling, ingredient list, and the name and place of business of the manufacturer, packer or distributor among the required label statements. FDA's Dietary Supplement Labeling Guide is a useful reason to capture those decisions early, not a substitute for destination-specific regulatory advice.
The practical goal is simple: help the people reviewing the project distinguish a product decision from an unanswered question. An early brief can say “powder preferred, format not final” or “packaging reference supplied, component specification open.” That is more useful than presenting an incomplete preference as a confirmed requirement.
Before you begin: make four columns for every decision
Create one shared brief, spreadsheet or document. For each item, add one of four labels:
| Status | Meaning | Example |
|---|---|---|
| Fixed | A decision the brand does not expect to change without formal review. | The intended launch market is Canada. |
| Preferred | A direction the brand wants to explore, subject to feasibility. | A single-serve powder format is preferred. |
| Open question | A decision that needs technical, commercial or regulatory input. | The suitable package configuration is not selected. |
| unconfirmed | Information, evidence or a provider decision is unavailable. | No approved claim-support file is available. |
Step 1: Define the product direction and use occasion
By the end of this step, you should be able to describe the proposed product in one plain-language sentence. Include the audience you want to serve, the consumer routine you are designing for and the broad product direction. Do not write a health outcome as if it were already substantiated product copy.
For example: “A daily, adult-facing nutrition product intended for a morning routine, with a portable use experience.” This gives a reviewer a starting point without claiming efficacy, a dosage, an ingredient profile or a final format.
Add the following fields:
- Working product name or internal project code.
- Intended audience and use occasion.
- Product direction in neutral language.
- Existing brand positioning or reference products, marked as references rather than specifications.
- Decisions that are intentionally out of scope for this first conversation.
If a public claim, before-and-after message, testimonial or health benefit is part of the concept, flag it rather than polishing it into marketing copy. The FTC says objective health-product claims must have adequate substantiation before dissemination, and that the appropriate substantiation depends on the product and claim. FTC Health Products Compliance Guidance applies this discussion to U.S. advertising. It does not approve a claim for your product, and it does not replace advice for the market where you plan to sell.
Step 2: Describe the Format and Serving Size
By the end of this step, the brief should show how the consumer may receive the product, even if the final format remains open. Record whether the product may be swallowed, chewed, mixed, measured or used in another defined way. Add any preference about serving count, portability, taste, texture or preparation.
Do not assume that an ingredient list can move unchanged from one format to another. A format decision can affect the consumer experience, the amount that must fit into a serving, packaging choices and the questions a technical review needs to ask. To frame those choices without making a capability claim, use the supplement format selection guide and the VITHELO product format overview as decision references.
Useful brief entries include:
- Preferred and alternative formats.
- Intended serving experience and any sensory priorities.
- Whether the product needs to be portable, measured, mixed or consumed with water.
- Any packaging reference that affects the use experience.
- Known exclusions, such as formats the brand does not want considered.
Explain why you prefer a format: ease of use, serving size, taste or packaging. If you are undecided, ask the manufacturer to compare the options against your ingredients and target customer.
Step 3: Share Your Formula or Ingredient Requirements
By the end of this step, a reviewer should know whether you have a finished formula, a partial ingredient direction, a benchmark or no formula information yet. Attach the source file when you have permission to share it. If you do not, summarize only what you can support.
Capture each ingredient or formula instruction with its status. For example, “ingredient list supplied by brand, quantities pending review” is materially different from “final formula approved.” If you have evidence for a claim, identify the exact product or formula version it concerns. If you do not, use unconfirmed rather than importing support from a different product, ingredient, dose or format.
This distinction has a practical basis in the U.S. dietary-supplement CGMP framework. FDA guidance explains that a master manufacturing record for a unique formulation and batch size includes components, the identity and measure of dietary ingredients, packaging and a representative label. FDA's small entity CGMP compliance guide explains why formula, packaging and label decisions need to be recorded together for applicable US projects.
At this stage, collect:
- The current formula file, ingredient direction or benchmark product reference.
- Any known restrictions, exclusions or required ingredients, with their source.
- The intended serving expression, if known.
- The claim concept and its evidence status, not a marketing conclusion.
- Ownership and permission to share confidential material.
For a product intended outside the United States, identify the destination before treating any U.S. guidance as relevant. Local classification, ingredient, labelling, notification and advertising requirements may differ. Obtain destination-specific professional advice before making legal or market-access decisions.
Step 4: Describe Your Packaging
By the end of this step, the team should know what packaging direction exists and which parts are undecided. A reference image, target shelf context or pack-use requirement can be enough for an early conversation. It is not a finished artwork pack or evidence that a proposed configuration is feasible.
Record the pack type you prefer, the product count or net-content direction if known, any required language or market context, and whether the brand owns the artwork. Put components, print specifications, artwork approval and final label review in the open-question column until they have been confirmed for the selected route.
The U.S. FDA labeling guide is useful context here because label information and placement are defined parts of the U.S. dietary-supplement framework. It should not be used as a universal packaging checklist or as evidence that a label will be accepted in another market. Ask the appropriate destination reviewer which requirements apply.
Discuss minimum orders, pricing and production timing once your formula, packaging and quantity are clear. Read how packaging affects MOQ and lead time to prepare those questions.
Step 5: Name the Target Market and Approval Contacts
By the end of this step, the brief should identify the market you intend to enter, the sales-channel context and the people who can decide on brand, product, regulatory and commercial questions. “Global” is not enough context for an early compliance review. List each target country or region, then indicate whether it is fixed, preferred or still open.
For each market, note the proposed language, channel, launch sequence and the person responsible for approving product copy and artwork. Separate these facts from the evidence that may be needed to support a claim. In the United States, the FTC distinguishes its advertising oversight from FDA responsibilities for labeling, while emphasizing that health-product claims should be truthful, non-misleading and adequately substantiated. That guidance is not a checklist for every jurisdiction, but it supports the practical habit of assigning a claim owner before marketing material is released.
If your buyer requires a certificate or market-specific document, name it in the brief. Ask who will provide it and check that it covers the relevant production site and product.
Step 6: Prepare Questions for the Manufacturer
By the end of this step, your team should know whether it is seeking an exploratory feasibility conversation or a comparable commercial response. An initial brief asks what must be reviewed next. A formal RFQ needs more stable commercial and technical inputs so that assumptions can be compared.
Move to an RFQ only after the project direction, preferred format, formula position, packaging scope, market context and expected commercial basis are sufficiently defined for the purpose of the request. The dedicated supplement manufacturing RFQ guide provides the quote-request checklist. Do not ask this early-stage article to provide an MOQ, lead time or price estimate.
If you have not chosen between an available formula and custom development, compare private label and custom formulation. Use the sampling guide to prepare taste, texture and other sample criteria.
Your First Enquiry Checklist
Copy these fields into one shared brief. Mark each entry fixed, preferred or open; leave unanswered fields visible. The bracketed entries below are prompts to replace with your own project inputs, not example specifications or supplier commitments.
| Field | Your entry | Decision status |
|---|---|---|
| Product and use occasion | [One sentence describing the intended product and routine] | [Fixed / preferred / open] |
| Format | [Preferred format and acceptable alternative] | [Fixed / preferred / open] |
| Formula file | [Attached version / ingredient direction / none yet] | [Fixed / preferred / open] |
| Pack | [Type, count direction and artwork version, if known] | [Fixed / preferred / open] |
| Market | [Country, language and sales channel] | [Fixed / preferred / open] |
| Open decisions | [Question, responsible person and next review] | [Open until resolved] |
| Requested next step | [Feasibility discussion / clarification before RFQ] | [Agreed internally / open] |
Before a first OEM or ODM discussion, check that you can share the following without filling gaps by assumption:
- Working product direction, audience and use occasion.
- Preferred format and the consumer experience it should support.
- Formula status, source files and known restrictions.
- Packaging direction and what is not yet approved.
- Target market, language and sales-channel context.
- Claim concepts with evidence status, or unconfirmed where evidence is absent.
- Decision owners and the questions that still require review.
- A clear statement that commercial quantities, MOQ, cost, capacity, timing, certificates and documentation availability are not confirmed in this brief.

Example: a First Powder Supplement Brief
The following is a fictional planning example, not a VITHELO product or quotation. Copy the fields and replace the example entries with your requirements.
| Field | Example entry |
|---|---|
| Product and audience | A flavored powder for adult customers who prefer mixing a serving into a drink. |
| Formula starting point | No final formula. Ingredient shortlist to be supplied for review. |
| Serving experience | Single-serving stick pack; serving weight still to be reviewed. |
| Sample goals | Compare two flavor directions using the same mixing method. |
| Packaging | Stick packs in an outer carton; pack dimensions and carton count open. |
| Market and approvals | Intended market to be named; our team will appoint formula and artwork approvers. |
| Commercial planning | Initial quantity and target launch date to be supplied; request applicable minimums. |
| Next decision | Identify the inputs needed to prepare the first sample. |
This brief asks for development guidance. Once the formula, pack and quantity basis are clearer, use the supplement RFQ guide to request comparable commercial responses. Explore powder manufacturing for mixing and pack inputs.
Frequently asked questions
Do I need a final formula before contacting an OEM or ODM partner?
No. At VITHELO, you can choose from our existing formulas or ask us to develop a custom formula based on your requirements, target market and product positioning. Share your product idea, ingredient preferences or a reference product; we will help you choose the formula and format.
Do I need final packaging artwork?
No. Share your packaging idea, brand artwork or a reference image. We can help develop the packaging and label design; the final artwork and label requirements are checked for your target market before approval.
Should I include a target MOQ, price or launch date?
Yes. Include your estimated order quantity, target budget and launch date if you have them. We use these to assess suitable formula and packaging options, then confirm the quotation and schedule for the agreed specifications.
Can this checklist confirm regulatory compliance?
No. This is a project-preparation checklist, not legal or regulatory advice. It uses U.S. FDA and FTC materials only to illustrate why early product, label and claim inputs matter. Confirm the rules and approval path for each target market with qualified professionals.
Send Your Product Brief
Prepare a brief that separates what you know from what needs review. A concise product direction, format preference, formula status, packaging direction and market context are enough to start an informed conversation. Keep claims, commercial terms and capability assumptions evidence-bound until project-specific confirmation is available.
