You agreed on price on a call, sent a 30% deposit, and the factory shipped. The rings arrived in the correct alloy but the stones are 0.2 mm smaller than the sample, the karat stamp sits crooked, and the supplier says "that is normal for this line." There is no document to point at, because your "order" was three chat screenshots. A first wholesale jewelry order only protects you when it is written, specific, and signed by both sides before the deposit leaves.

Why a PO is the only document that holds up

Chinese jewelry factories run on proforma invoices, not on the long legal contracts used in Western B2B. The proforma invoice plus your countersigned purchase order is the enforceable pair. In a dispute, escrow platforms and Chinese courts read those two documents and the chat records attached to them — they do not infer "industry standard." Every spec you care about must be on the PO, because anything omitted defaults to the factory's interpretation. Before you send the first PO, make sure the supplier itself passed the basic vetting in how to audit a Chinese jewelry factory; a clean PO sent to a trader is still a lost order.

The 11 line items every PO must carry

SKU and design reference — your internal SKU plus the factory's mould or design number. Both. One without the other leads to the wrong mould being opened.
Material and alloy — "925 sterling silver," not "silver." Include the stamp that must appear: 925, manufacturer's trademark, and any origin mark required for your market. This is the FTC 16 CFR Part 23 stamp requirement in writing.
Stone spec per piece — type (moissanite, cubic zirconia, natural gemstone), shape, carat weight range, colour and clarity grade, and whether a certificate accompanies it. For moissanite lines, see GRA vs IGI vs GIA paper.
Finish and plating — rhodium, 14K gold flash, PVD, with a thickness target in microns where the factory will commit. Nickel-release test reference for EU lines (EN 1811).
Size and quantity breakdown — ring sizes 6-9 in even splits, earring pairs as pairs (not pieces), bracelet lengths. Write the size chart on the PO, do not attach it verbally.
Unit price and currency — FOB port, USD, with the FX rate locked at order date.
Packaging — polybag, hang tag artwork version, pouch or box reference. Tie to your private-label tag and box system.
Lead time and delivery date — production days plus shipping days, with a calendar date, not "end of month."
Payment schedule — deposit percent, balance trigger (pre-shipment inspection report, or copy of bill of lading). Match to the structure in TT vs escrow vs LC.
Inspection and rejection clause — third-party QC right, acceptable defect rate (1-2% is standard), and who pays for rework or replacement.
Spare pieces — ask for 2-3% extras at no charge for QC samples and replacements; this is normal in jewelry.

The clauses small buyers forget

Three short sentences prevent most disputes. First, "golden sample signed by both parties governs; bulk production must match within agreed tolerances." Second, "any substitution of stone, alloy or plating requires written approval before production." Third, "factory retains 10% of balance until pre-shipment inspection passes." These cost the factory nothing to accept. A supplier that pushes back on any of them is telling you, in writing, that they intend to substitute — move on. For the minimums side, your PO should also lock the reorder price ladder discussed in MOQ negotiation for small buyers.

What the golden-sample step actually costs

Before the bulk deposit, pay for a pre-production sample (often USD 30-80 per SKU, sometimes credited to the bulk order). Photograph it against a ruler, a colour card and a 10x loupe, sign two copies, and keep one. That signed sample is the reference the inspector compares the bulk against. Without it, a "slightly smaller stone" dispute has no baseline. Budget the sample, the third-party inspection (USD 150-250 per order) and the PO drafting itself into the launch cost: roughly USD 400-600 on a USD 5,000 first order. It is cheaper than one rejected shipment.

FAQ

Does a WeChat voice message count as an order agreement?

No, in practice. Escrow platforms and Chinese dispute channels rely on written documents and dated screenshots. A verbal agreement on a call is not enforceable; convert every call decision into a short written follow-up message and ask for "please confirm."

Who drafts the PO — us or the supplier?

You. Send your own PO template with the 11 items above; the supplier issues the matching proforma invoice. Never accept a proforma invoice that omits a spec you negotiated — renegotiate in writing before deposit.

What is a realistic defect tolerance to write in?

1-2% of pieces on visible finish and stone security, zero tolerance on karat stamp errors and stone mis-description. Anything above 2% should trigger rework or discount on the affected SKU.

Should we hold back balance for a first order?

Yes. A 30% deposit and 70% against pre-shipment inspection report is standard for first orders. Release balance only after the QC agent sends dated photos and a pass report.

HOLYCOME works from buyer-side PO templates: we countersign your spec sheet, run signed golden samples, and accept pre-shipment third-party inspection before balance release. Ask for our PO template and sample cost sheet for your first order.
