A buyer in Manchester narrowed a 40-supplier shortlist down to two: one quote was 18% lower but the company had no visible workshop, the other was more expensive but sent a video of the soldering line. She picked the cheaper one — and her order arrived in a factory's standard polybag with a different maker's mark. The supplier was a trader. This is not a mistake; it is a category error. Factories and traders are different tools, and the right choice depends on what you are buying.

What a factory actually is (and is not)

A real factory owns the benches, the plating line and the QC room. It can change a design on the bench in 48 hours, it controls plating thickness, and it carries its own maker's mark. Its weak spot: it usually only makes one product type (silver casting, or platinum setting, or stone cutting). It will not happily mix categories. The verify a moissanite supplier is a real factory checklist applies to any category.

What a trader actually does

A trader (or trading company) is a reseller that aggregates from 5–30 small workshops. Its strengths: one PO across silver, brass, stones and packaging; faster response; lower MOQ on mixed baskets. Its weaknesses: no price transparency, no control over plating, and zero design agility. A trader's "custom" job usually means asking a factory you could have found yourself. Our note on auditing a Chinese jewelry factory on first order walks the walk-through.

Match the supplier type to the buy

Use a factory when: (1) you need 500+ pieces of a single design, (2) plating or alloy is a selling point, (3) you want a private maker's mark, or (4) you expect design iterations. Use a trader when: (1) you are filling a 20-SKU test basket at 20 pieces each, (2) you need packaging and small accessories bundled, or (3) your lead time is 14 days and you cannot risk a factory minimum. See MOQ negotiation for small buyers and wholesale catalog SKU structure.

Pricing: what the gap actually is

A trader usually marks up 8–15% over factory price. That sounds high, but when you add the cost of flying to two cities, booking two hotel weeks, and handling three separate shipping files, a trader on a small basket often wins on total landed cost. On a 5,000-piece reorder, the same trader costs you USD 3,000–5,000 of avoidable margin. The rule of thumb: first test basket through a trader, reorders direct to a factory once you know the SKU sells.

Red flags on both sides

A factory that refuses a live video walk-through, quotes "1,000 designs on hand" (factories run 20–100 active SKUs), or cannot produce a plating spec sheet. A trader that refuses to name the actual factory, sends identical prices to every customer, or pushes you into DDP shipping they cannot actually support (see insured parcel shipping from China).

What the contract should say either way

Whichever type you pick, the PO should name the actual manufacturer on the invoice (not just the trading company), state the alloy and plating spec, and include a remake or credit clause for defects above 3%. The jewellery manufacturing reference lists the standard process steps — casting, setting, polishing, plating — and you can use that list as the walk-through checklist.

One more signal: a factory will quote you a lead time in days and hold it. A trader will quote in weeks and slip. If the first order slips by more than 5 days without a written reason, treat that as a forecast of every future order.

FAQ

Can I use the same supplier for both test orders and reorders?

Yes, but expect to renegotiate. A trader who wins your first USD 3,000 order will often give way on margin when you place a USD 15,000 reorder — or you will move direct to the factory they were already using.

How do I tell a factory from a trader on Alibaba?

Ask for a video of the workshop right now, not a pre-shot film. Ask how many benches are in the soldering room. Ask which of the listed designs were made in-house last week. A trader will deflect.

Are trading companies always worse quality?

No. A good trader runs QC on top of the factory QC. A bad factory with bad in-house QC can be worse than a trader who inspects. Judge on the sample, not the business card.

Should I sign an exclusivity agreement with a factory?

Only if you are buying 30%+ of their output. Otherwise exclusivity locks you in without real protection — they can still sell the same design to your competitor.

HOLYCOME operates as a hybrid: owned silver and stone-setting workshops for core lines, plus a vetted factory network for extended SKUs. Ask for the current production walk-through and a sample so you can see the maker's mark and plating finish before ordering.
