Third-Party Manufacturing Process: From Brief to Bulk, Stage by Stage

Third-party manufacturing runs in about ten stages from your first brief to a shipped bulk order, and the stage where most brands lose weeks is not production but the waiting between approvals, artwork and packaging delivery. For a ready formula, samples typically reach you in 5 to 7 days; for a custom formula, 2 to 4 weeks; and production usually takes 15 to 25 working days after formula and packaging approval.

Below is the whole path, stage by stage, with what you hand over and what the manufacturer hands back. It is the practical companion to the complete guide to third-party cosmetic manufacturing in India. The timelines quoted are those Harrods Health works to; other manufacturers differ, so confirm yours in writing.

Stage 1: The brief

You provide: product type, target customer, positioning, preferred format (cream, serum, shampoo, balm, mist), fragrance direction, key ingredients you want or want to avoid, target markets, first-order quantity and a rough launch window.

Manufacturer provides: a response on feasibility, whether a ready formula fits or a custom one is needed, and the minimum order. At Harrods Health the minimum is 500 units per product.

A one-page brief beats a long chat thread. Brands that skip this step tend to discover mid-project that they wanted a different texture or a different market.

Stage 2: Choosing ready formula or custom formulation

A ready (private label) formula is already developed and tested by the manufacturer, so it is faster and has a lower entry cost, but you license it rather than own it. A custom formula is built to your brief and is slower and costlier to start. The formula ownership guide explains why this choice has consequences for years, and private label vs white label vs OEM vs ODM sets out the models.

Stage 3: Quote and commercial terms

You provide: quantities, pack preferences, delivery location, and whether you need export documents.

Manufacturer provides: a written quote with validity period, MOQ, payment terms and the lead time. Read it line by line using the quote guide, because freight, tests and artwork are often excluded.

Stage 4: Samples

You provide: your shipping details and honest feedback against the brief.

Manufacturer provides: ready-formula samples, which for qualified brands are free and dispatched in 5 to 7 days at Harrods Health, or custom-formula samples, which take longer, typically 2 to 4 weeks.

Test the sample like a customer would. Use it for a full week, leave it in a warm room, refrigerate part of it, and compare against your reference product. Write feedback as specifics (too thin, fragrance fades after an hour, pump dribbles) rather than general reactions. Each revision round adds time, so batch your comments into one list.

Stage 5: Stability, compatibility and safety checks

These run in parallel with sample refinement and must finish before bulk goes ahead. See the stability and safety testing guide for who commissions each test. Agree early which reports you expect to receive.

Stage 6: Packaging and artwork

You provide: final artwork files, label copy, barcodes, batch-code format, and any claims. Make sure ingredient lists, net quantity and mandatory label details are correct for your target market and check current rules with your regulatory adviser.

Manufacturer provides: dielines or label templates, packaging component options, sourcing if you have asked them to supply packaging, and a proof for your approval. The packaging guide sets out who sources what, and the stock vs custom packaging article explains why custom components can have their own minimums and lead times.

Packaging is the stage with the longest quiet gaps. Custom bottles, printed cartons and tubes are rarely ready at the same moment as the formula, so start ordering them while the sample is still being refined, not after it is approved.

Stage 7: Pre-production approvals

You provide: written sign-off on the formula sample, the packaging proof and the final specification.

Manufacturer provides: a final specification sheet, a confirmed production slot and a pre-production sample or pilot batch if one has been agreed.

Production lead time starts counting from approval of both formula and packaging, not from the date you paid the deposit. Many schedule arguments start with that misunderstanding, so ask the manufacturer to state in writing what the clock is attached to.

Stage 8: Bulk production

Once formula and packaging are approved bulk production typically takes 15 to 25 working days at Harrods Health. Within that window the manufacturer manufactures the bulk, fills, labels, cartons and packs your order.

You provide: a prompt answer to any query, because a stalled question about a barcode or a carton count can hold the line.

Manufacturer provides: progress updates and batch records. If you want to understand what should be in them, the quality system guide lists them.

Stage 9: Quality control and release

Before dispatch, the finished batch should be checked against the agreed specification and released against a Certificate of Analysis. Ask for the COA, a photo or video of the finished goods, and retained samples held under your batch code. If anything is out of specification, you want the manufacturer's corrective action in writing before the goods leave the factory.

Stage 10: Dispatch and documents

You provide: consignee details, shipping mode, and any importer documents your destination requires.

Manufacturer provides: packing list, invoice, and for export orders the COA and MSDS. Harrods Health ships to 30+ countries and handles export documentation. Freight, duties and import clearance are often outside the quote, so decide who owns them before you reach this stage. The fulfilment and export page describes the options.

Where the time actually goes

The manufacturer's published timelines are the easy part. The delays that stretch a project from a few months into a much longer one usually come from your side of the table or from the supply chain:

• Late or revised artwork. Changing a claim or ingredient list after proof approval restarts printing. Lock the label text before you request a proof.
• Packaging lead time. Custom components may take longer than the formula, and imported ones can be slower still. Order them in parallel with sampling.
• Slow approvals. A sample that sits for a fortnight without feedback means production capacity is given to someone else. Set a deadline for your own decisions.
• Scope changes mid-project. Changing fragrance, colour, size or pack after sample approval triggers new samples and may need new stability checks.
• Payment timing. Production slots are usually confirmed against the agreed advance, so a late payment moves the slot.
• Documentation gaps. Export orders stall when the importer asks for a document nobody planned. Ask your importer for the list before the order is placed.

A working checklist to keep the project moving

1. Send a one-page brief, then ask for the manufacturer's timeline in writing.
2. Collect all feedback in one list per sample round.
3. Finalise label copy before the packaging proof, not after.
4. Order custom packaging as soon as the format is fixed.
5. Agree who holds the schedule: one named contact on each side.
6. Confirm in writing what starts the production clock.
7. Plan the reorder from day one. The MOQ and reorder guide covers forecasting after the first batch.

If you are choosing a partner

A manufacturer that can describe each of these stages without hesitation is usually one that runs them well. The vetting checklist helps you check that, and the how we work page shows how Harrods Health arranges the same stages. For a conversation about your own product, use the contact page.
