Guides for sourcing 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. 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. 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. 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. 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. 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. 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. 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. 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. 9 min read Three regimes, three different jobs. Which one applies depends less on the product than on the market you are entering. 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. 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. 7 min read

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 market compliance matrix compares five destinations, 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 guides are written by the factory side of Slow Duo, a dual-motor wellness range supplied wholesale and OEM only — which is the perspective they take, and the one thing a buyer should discount them for.
