Sourcing guides for a wellness device range

12 working guides for the questions a procurement team asks before it shortlists anybody: how to choose a manufacturer, what a minimum order quantity actually covers, where lead time really goes, and what water-resistance ratings mean. Written from the factory side, with the commercial terms published rather than withheld.

Choosing a supplier

Not a list of factories. A shortlisting method — five stages, each with the evidence to ask for and the answer that should end the conversation. Answers Which of three candidates can actually produce the evidence you asked for, and which is answering a different question. 9 min read A walkthrough you can complete before lunch, ordered so that what you see first tells you most — including the one question no report can answer. Answers What to look at, in what order, in the single day you have on site — and the one thing no document can tell you. 8 min read The most quoted number in wholesale QC, and the most misunderstood. What it promises, what it does not, and how to read a plan before you sign it. Answers Whether a lot passes, and what the accept number in your purchase order actually commits the factory to. 7 min read Three labels, one decision: how much of the product is already decided. Everything downstream — tooling cost, minimum, lead time, exclusivity — follows from that. Answers Which route puts your name on the product for the least tooling, and what each one leaves you owning. 8 min read

Commercial terms

Minimums are not arbitrary and they are not a negotiating position. Understanding what one covers is the fastest route to a smaller first order. Answers What the 300-unit minimum covers, what carries a minimum of its own, and how mixed models count. 8 min read Production is usually a minority of the elapsed time in a first order. The rest is decisions, and most of them are yours. Answers Which weeks are production and which are waiting for you to approve artwork, deposit or a sample. 8 min read Most held shipments are not rejected products — they are missing documents. What each market wants, what it accepts as evidence, and which heading sets the rate. Answers Which documents each border asks for, and what duty attaches once they have cleared. 13 min read The third minimum in a quotation is usually the one nobody discussed, and it is frequently the one that decides your first order quantity. Answers What a printed box commits you to in units and in days, and what can wait for the reorder. 7 min read

Materials & compliance

Most suppliers say "high-grade silicone". Almost none can tell you what that means. Here is what to specify, and what to ask to find out. Answers What “body-safe” can be evidenced as, and what the material certificate measures rather than promises. 9 min read Three regimes, three different jobs. Which one applies depends less on the product than on the market you are entering. Answers Which of the three regimes applies to your market, where they overlap, and which report answers which. 8 min read The numbers look like a ladder. They are not — each is its own test, and the difference matters for both marketing copy and warranty. Answers What the rating on your listing may claim, and the one claim it must not make. 7 min read Same number, different world. A decibel figure without distance and speed attached is not a specification — it is material for a marketing claim. Answers Why two decibel figures for the same unit disagree, and which of them is comparable to another model. 7 min read

Where to start, by what you already have

These sourcing guides are ordered by decision, not by date. Twelve guides read in the order they were written is a reading list; read in the order your situation demands, they are a decision path. If you have a product and no factory, the sequence is how to choose a manufacturer, then the audit checklist before you book a flight, then AQL 2.5 once a purchase order exists. Three documents, one shortlist.

If you have a factory and no range, the constraint is commercial rather than technical: OEM, ODM or private label decides how much of the product you actually own, and the MOQ arithmetic decides what a first order costs to place. Neither question is answered by a better sample.

If the range exists and the problem is the border, read the three regimes compared against the table itself rather than one after the other — the matrix is the table, the guide is the argument about which column will hold you up. Whichever situation you are in, the wholesale terms and the range itself are the two pages the rest of this cluster is describing.

If you would rather have the data than the argument

The reference layer sits next door: the documents a shipment carries lists every document a shipment carries, the destination comparison sets five markets side by side, and the MOQ and lead-time table works four volumes through the published terms.

For the commercial terms themselves see wholesale and OEM and private label; for the engineering behind every claim see technology and compliance.

These sourcing guides are written by the factory side of the Slow Duo dual-motor wholesale range, supplied wholesale, OEM and ODM only — which is the perspective they take, and the one thing a buyer should discount them for.

Where to start, and in what order

I have never bought from a factory — how to source a vibrator?

How to source a vibrator runs in the order the decisions arrive: shortlist a manufacturer, audit what you cannot see, agree the specification, then agree the terms. The guides are ordered that way rather than alphabetically, because reading them out of order costs a buyer a season.

Start here: how to choose a vibrator manufacturer
Are these procurement guides, or marketing with a contents page?

Procurement guides. Each one states the decision it serves, the evidence to ask for, and the number that changes the answer — including the cases where the honest answer is that we are the wrong supplier.

The tables and checklists these guides cite
Which guide do I read if the specification is already agreed?

Then skip to terms: MOQ, lead time and import compliance are the three that decide whether an agreed specification can actually be landed at the cost you modelled.
