When a factory quotes '25-35 days' for OEM jewelry, that number hides a lot. A simple polished silver band with no stones is a different product than a pavé-set sterling silver statement ring with 60 melee stones, and the lead time between them doubles. If you plan your launch calendar against the optimistic end of the range, you will be late. Here is how the timelines actually break down by product, and where the MOQ and tier pricing land.

Lead time by product type

The numbers below cover a repeat order with approved CAD and wax proof. A first order adds 7-15 days for the design and sampling gates. Reorders of the same tooling skip CAD and wax, so the timeline collapses to production only.

Product type	Reorder lead time	First-order lead time	Typical MOQ
Plain bands / signet rings	15-20 days	25-30 days	50-100 pcs
Sterling solitaire rings (1 stone)	20-25 days	30-38 days	50 pcs
Pavé / multi-stone rings	30-45 days	45-60 days	30-50 pcs
Stud earrings (pair, 1 stone each)	20-25 days	30-38 days	100-200 pairs
Drop / dangle earrings	25-35 days	35-45 days	100 pairs
Chains (cable, rope, snake)	30-45 days	40-55 days	100-300 pcs
Pendants (1 stone, bail included)	20-25 days	30-38 days	100 pcs
Bracelets (chain + charm)	25-35 days	35-45 days	100 pcs

MOQ bands and how to negotiate them

MOQ is not a wall; it is the smallest batch that makes a worthwhile run for the workshop. A factory that quotes 100 pieces per style usually means it wants 100 pieces of that design to justify the setup, the casting tree, and the QC passes. You can almost always bring that down in one of three ways:

Blended MOQ. Ask for 50 pieces per style across 8 styles, totalling 400 pieces. The workshop still gets a worthwhile run, and you get a test range.
Shared tooling. Use a common shank, chain or bail and vary only the top element. Tooling cost drops and MOQ flexibility rises.
Phased order. Place 50 pieces now with an agreed reorder price, and commit to 150 more within 60 days. The factory prices the first batch as if it were the full run.

What you should not do is push MOQ below the point where the factory cannot recover its setup cost. A 20-piece custom ring order will be priced like a sample, because for the factory it is one. You will pay $25-$40 per piece instead of $8-$12. The discount curve flattens above about 300 pieces, which is where most wholesale buyers land.

Tier pricing in practice

Tier pricing is not just a volume discount; it reflects how the factory recovers fixed costs. Setup (CAD, tooling, first article) is fixed per style. Unit cost then drops as volume absorbs it, because casting trees pack more pieces per burn-out and bench time per piece falls.

50-100 pieces: near-sample pricing. You pay for the design and a short run.
200-500 pieces: standard wholesale. Unit cost typically 15-25% below the 100-piece price.
1,000-3,000 pieces: production pricing. Unit cost another 10-15% lower, and the factory prioritizes your slot.
5,000+ pieces: contract pricing. Worth negotiating annual terms, standing stock, and dedicated tooling.

Ask the factory to show you the price ladder in writing rather than negotiating each order fresh. A published tier sheet means your reorders are predictable, and it prevents the quiet price drift that happens when you renegotiate from scratch every season.

Logo, packaging and private-label extras

The 'OEM' part of private label adds time that buyers forget to budget. Engraving your logo inside a ring shank is quick (1-2 days), but custom laser-engraved pouches, printed cards, custom boxes with foil stamping, and hangtags each add 7-14 days because they run through a separate packaging supplier. If your launch depends on branded packaging, order the packaging stock 30 days before the jewelry ships so it is ready to pack on arrival.

Rush orders are available at most factories, usually at a 25-50% premium and a 30-40% timeline cut. They are useful for a trade show deadline but not a sustainable operating model, because rush slots displace other production and QC corners get cut. Plan the launch calendar against the normal timeline and keep rush as insurance.

One variable buyers forget to budget is the approval round-trip. Every time a CAD revision or a wax proof needs to be shipped, reviewed and approved by you, that adds 3-7 days: a day to courier the sample, a day or two for your team to look at it, and a day to relay the comments back. Two approval rounds on a 30-day project can stretch it to 40. The fix is to review proofs within 48 hours and to batch your comments into one reply rather than sending them piecemeal.

What to put in the OEM PO

A clean OEM purchase order names: style number, approved CAD revision, metal and weight tolerance, stone specs and setting type, finish and plating thickness, logo placement and size, packaging, tier price, delivery date, and the reorder price for the next batch. That one document prevents 90% of the disputes that arise on private-label work. We include a template on our OEM & ODM page so first-time brands can send a PO that reads like a seasoned buyer wrote it.
