One Formula, Several Markets: Four Checking Lines for a Cross-Market Launch

Decide which rule set applies before you check anything

A formula that can be sold in one market is not thereby sellable in another. The first step is to list the destinations one by one and, for each, identify the framework the product will be judged under: an ordinary food category, a supplement category with its own rules, or a regulated health product; which authority administers it; and whether something must happen before sale.

This step gets skipped more often than any other. The usual pattern is to build the product on one market's assumptions and then walk it through the others one at a time. The formula often survives, but the labelling and paperwork are rebuilt from scratch, at a far higher cost than checking each market at the start.

Separate two kinds of difference before you cost anything:

• Rule differences — a material is permitted in one market and not in another, or the limits differ. These flow into the formula.
• Enforcement differences — the material and the limits are fine, but the label format, the claim wording or the entry paperwork differ. These usually do not touch the formula.

Deciding which kind of difference you are looking at tells you where the cost lands.

Line one: which materials are permitted

For each market, check each material in turn:

• Whether the material is permitted at all for this kind of product there, and whether permission is limited to a particular category.
• The conditions of use — restricted to a food category, a particular population, or a particular form?
• The limits — maximum level or maximum daily intake, and the basis on which the figure is calculated.
• Specification and quality requirements, plus the excipients and processing aids: capsule shells, carriers, lubricants and coatings all enter the same check.

The three markets treat this line differently in structure. In the United States, dietary supplements sit inside their own current good manufacturing practice regime, with the records a manufacturer must keep set out in the federal regulation — see 21 CFR Part 111 — while permitted materials and conditions of use sit in the surrounding provisions of the same title; check the current text rather than a summary or a supplier's list. In the EU, materials are treated as food ingredients and food supplements under the general food law framework. In Thailand, food supplements are handled by the Thai Food and Drug Administration, and materials have to fall within what has been notified or accepted for that purpose, some through ASEAN-level notifications; the Thai FDA's English site is where to confirm the current position.

One detail is easy to miss: the same material can be treated differently across formats and positioning, so check "material × format × audience" as the smallest unit.

Line two: daily intake limits and the claims attached to them

A material that is permitted is not permitted at any dose or with any wording attached.

Keep three levels apart:

1. The amount added in the formula — what goes into the batch.
2. The content in the finished product — what is there after blending and processing. Add and finished content are not the same number wherever blending uniformity or processing losses differ.
3. The labelled amount and the suggested serving — what a consumer can actually take.

The three have to be connected before you can say whether the daily intake of a component sits inside a market's limit. The calculation basis also differs, so ask each framework what it counts: per unit of the ingredient as supplied, per unit of the active, or per consumer per day.

Claims are a separate dimension, and each market handles them in its own way. The EU has a specific framework for nutrition and health claims, with conditions and authorised wording published by the Commission — see the nutrition and health claims page. In the US, claims fall into categories whose conditions and substantiation differ, and the labelling provisions sit in the same federal title as the manufacturing rules. In Thailand, claims have to be consistent with what has been notified or registered for the product. Permission in one market says nothing about another.

A higher content is not a better product. Where a market sets a ceiling, a formula above it cannot be sold there in that category. Within the permitted range, consistency of the finished product matters more than adding more.

Line three: labelling language, format and mandatory particulars

This is usually the layer that needs the most rework. Check, market by market:

• Mandatory particulars — product name, ingredient list, net quantity, producer information, date of minimum durability, storage conditions, the nutrition declaration, and any licence or registration number the market expects. The set differs by market and so does the wording.
• The nutrition declaration — which values appear, how a serving is defined, and the rounding and exemption rules.
• Claim-related particulars — nutrient content claims, health claims, suitability notes, warnings.
• Language, format and traceability — language, legibility, type size, placement, lot number, date of manufacture and traceability coding.

This layer changes packaging, not the formula: the usual pattern is one production run of content, then per-market artwork and packing.

For the EU, the particulars and the nutrition declaration follow the food information to consumers rules summarised on the Commission's legislation page; read the current text for your product type rather than reusing another market's template. In the US, expect the supplement labelling format, including the prescribed nutrition-facts panel. In Thailand, expect Thai-language labelling and the particulars required for the notified or registered product, confirmed with the Thai FDA.

Line four: registration, notification, import and entry paperwork

This line usually governs the schedule. Confirm, per market:

• What has to happen before sale — a notification, a registration, a licence or a label review, and whether the brand or a designated party is the applicant.
• Who is responsible for which document — an overseas manufacturer, an overseas contract party, a local importer, a local registrant.
• Import requirements — certificates of origin, free-sale certificates, ingredient safety dossiers, the form a test report must take, and the qualifications the importer must hold.
• Validity and format — how long documents remain valid, what must be resubmitted after a change, and whether submissions must be in the local language or a prescribed form.

None of this can be solved by adjusting the formula. It needs its own schedule, it is frequently the critical path, and it is better confirmed at project start than after the formula is signed off.

What can be shared, and what needs a market version

Shared across markets — the main formula and process route, provided materials are permitted and within limits everywhere; the production test items and methods, which can be bundled into one submission; and supplier documentation and incoming material records, provided the material itself is acceptable in each market.

Produced per market — the label and leaflet, with language, layout and claim wording; packaging artwork, with each market's printing and marking rules; the entry paperwork for that market; and part of the stability data, because storage and transport conditions differ.

Before commissioning a market version, find out where the difference sits. A difference at the labelling layer costs artwork and paperwork time; a difference at the formula layer costs new samples, new testing and possibly a new notification. Misjudging that estimate is what makes a project schedule collapse.

Fix the findings in a table you can reuse

When the checks are done, produce one table with a row per market. At minimum it should carry:

• The product category in that market and the source you relied on for it.
• Each material, with its permitted status, its limit and the basis on which the limit is calculated.
• The claim categories permitted and the evidence each requires.
• The list of mandatory label particulars.
• The entry paperwork, the responsible party and the expected lead time.
• The split between shared items and market versions, and anything to be re-verified.

Add the origin market's own requirements — the product's filing or registration category, the licence conditions the factory holds, and the national standards that apply to production and records — as a further column, because they constrain what the factory can do in every other market.

The value of the table is what happens next: adding a fifth market becomes a new column rather than a fresh exercise, and when a supplier or a formula changes, it is obvious which cells to reopen.

To discuss a specific project, use the OEM/ODM project enquiry form with the target markets, the format and the expected on-shelf date. The applicable requirements and any market-entry conclusion come from the current rules in each destination market and from a project-specific assessment.

If the project is still taking shape, the OEM/ODM project brief is where to write the markets down, choosing between softgel, tablet and powder settles the format, and verifying a manufacturer's certificates covers whether the factory's scope reaches the project.
