What goes wrong in a jewelry shipment
These are the defects that pass a factory's quick glance and reach your customer instead.
Stones that fall out before the first wear
Loose prongs and weak glue survive packing and shipping — then fail in the box. A loupe check catches them at the factory.
Plating that rubs off in transit
Thin coating and poor adhesion don't show in the factory's photos. They show up as one-star reviews.
Clasps that fail in the customer's hands
A lobster clasp that opens under a light pull turns a necklace into a return request.
Wrong or missing metal stamps
A 925 mark that isn't there — or shouldn't be — creates customs trouble and platform takedowns.
Mixed styles and short quantities
Multi-SKU jewelry orders get packed wrong more often than any factory admits on the phone.
Compliance holds at the border
Lead, cadmium and nickel limits apply to jewelry in the US and EU. "The factory said it's fine" is not documentation.
What a jewelry inspection covers
Every point below is checked against your spec sheet, approved sample and tolerances.
Workmanship & finish
Scratches, pitting, dents, tool marks, polish lines, solder marks, glue residue and sharp edges or points.
Stones & settings
Missing or loose stones, prong alignment, stone position and count against the spec sheet.
Clasps & closures
Lobster, spring ring, toggle and magnetic clasps opened and closed repeatedly to confirm they hold and release correctly.
Chains & links
Link soldering, kinks and twists, plus a pull check at the force you specify.
Plating & coating
Color match to your approved sample, tape-adhesion checks and rub tests on coated and printed surfaces.
Marks & labels
Metal stamps, logo engraving, country-of-origin marks, care labels and required warning labels.
Size & weight
Caliper measurements and unit weight on a scale, read against your tolerances.
Packaging & assortment
Pouches, boxes, hang tags, polybags, a barcode scan on every unit and the style mix per PO.
Checks that go beyond looking
Visual review catches appearance problems. These on-site checks catch the functional ones.
100%barcode scan — every unit scanned and matched to the PO, not just the sample.
76·61·46cmmaster-carton drop heights by weight bracket, so crushed corners don't reach your customer.
Per-specNpull force on chains, clasps and earring posts — measured at the force written in your spec.
Tape & rubadhesion and abrasion checks on plating, coating and printed surfaces before they ship.
Your spec sheet is the checklist.
Send your drawings, approved sample photos and tolerances. The inspector works through them point by point, and you get a pass, fail or hold with photo evidence.
Sampling that matches the value of the goods
Sample sizes come from ANSI/ASQC Z1.4 (ISO 2859-1). Special tests — pull, adhesion, carton drop — run on a smaller S-level sample. For high-value lots, a 100% full inspection checks every single piece. See the ANSI sampling tables for the exact quantities.
Level II
Default sampling
General inspection level II decides how many pieces are pulled from your lot size.
0 / 2.5 / 4.0
Acceptance limits
Critical, major and minor AQL values most jewelry buyers write into the booking.
100%
Optional full check
Every unit examined piece by piece when the order value or risk calls for it.
Lot size → pieces checked
281 – 500 pieces50
501 – 1,200 pieces80
1,201 – 3,200 pieces125
3,201 – 10,000 pieces200
What the numbers mean
A 5,000-piece order doesn't get 5,000 checks — it gets 200, drawn at random from packed cartons across the whole lot. If the defects in those 200 stay under your AQL, the lot passes. If they don't, you find out at the factory, not at your warehouse.
Sampling or checking every piece?
Most jewelry orders run on AQL sampling. Some shouldn't. Here is the honest split.
AQL sampling fits when
The order is a standard production run and you need a statistically sound answer in one man-day.
Cost
One man-day covers most lots — the cheapest reliable checkpoint.
Speed
Result the same day, report in 24 hours, shipment barely pauses.
Best for
Fashion jewelry runs, repeat styles, orders under roughly ten thousand pieces.
100% full inspection fits when
Every single unit is opened and examined. It costs more, and sometimes it is simply the right call.
Value
High unit value — fine-jewelry lines where one bad piece costs more than the check.
History
The last shipment failed, or the supplier is new and unproven.
Best for
Small valuable lots, reworked goods, and orders going straight to retail shelves.
How defects get classified
Every finding lands in one of three tiers, so the report tells you what actually matters. Details in our defect classification guide.
Critical · AQL 0
Sharp points or edges that can cut skin, a children's item missing a required warning, anything that fails a legal safety requirement.
Major · AQL 2.5
Missing stones, a clasp that doesn't hold, peeling plating, wrong metal stamp, a closure that won't close.
Minor · AQL 4.0
Slight polish marks or small color variation only visible at close range under inspection lighting.
Lead, cadmium and nickel are not visual checks
The rules that hit jewelry hardest are chemical, and no eyeball at the factory can settle them.
US · CPSIA
Lead and cadmium limits apply to children's jewelry sold in the United States — the strictest end of the market.
California · Prop 65
Adult jewelry sold into California carries heavy-metal exposure requirements and settlement history behind them.
EU · REACH / EN 1811
Nickel release is restricted for anything that touches skin — posts, clasps, chains and watch backs included.
On site we verify markings and declarations, then draw and seal samples for the chemical tests. The lab work runs through our laboratory testing coordination, so the shipment decision rests on documents, not promises.
Jewelry and accessories we inspect
Same discipline, adjusted checklist — each category carries its own failure points.
Fashion jewelry
Necklaces, earrings, bracelets, rings, brooches, pendants and matched sets.
Children's jewelry
Small-part hazards, sharp points, warning labels and CPSIA-related checks move to the front of the list.

A report your team can act on
Not a defect list that says "generally okay" — a document you can forward to the factory as-is.
Photo evidence
Every defect photographed at the inspection table, close enough to see the problem.
Classified counts
Findings split into critical, major and minor, against the AQL you booked.
Quantities & barcodes
Inspected versus passed quantities, barcode scan results and packaging status.
Clear recommendation
Pass, fail or hold against your criteria. The final shipment decision is always yours — the report gives you the evidence to make it.
If the goods fail, you still have options
A failed report is not the end of the order. It is the moment you still control what happens next.
Rework at the factory
Hand the report to the factory as-is — every defect is photographed and classified, so there is nothing to argue about.
Re-inspect only what was fixed
The follow-up visit checks the reworked quantity against the original findings, not the whole lot again.
Release part of the order
Passed styles or cartons can ship on schedule while the problem units stay behind. The report separates them cleanly.
How a recheck is scoped and when release makes sense: 100% full inspection after a failed FRI.
When buyers book a jewelry inspection
Four situations where one man-day at the factory is cheaper than the alternative.
First order, new supplier
Verify the factory can hold sample quality across a whole production run before you commit the balance.
Repeat order after a slip
The last shipment had loose stones or worn plating. This one gets checked before it leaves.
Before the balance payment
The inspection result lands in your inbox before the remaining 70% goes out the door.
Before a retail or FBA deadline
A failed batch found at your warehouse costs weeks. Found at the factory, it costs a rework.
What to send us before booking
Four things. The better these are, the sharper the inspection.
Spec sheet with tolerances
Measurements, weights, materials, plating color references — whatever the factory agreed to hit.
Approved sample photos
The inspector compares production pieces against what you signed off, not against memory.
Packing list & carton count
Total cartons decide how sampling is spread across the lot, and what "fully packed" means on the day.
Barcode, label & warning files
Every scannable code and every required mark, so "wrong label" is a fact, not an opinion.
What a jewelry inspection costs
No public rate card, because the honest answer depends on your lot. Here is exactly how the price is built.
Priced per man-day
Most jewelry inspections finish in one man-day. Large lots, many SKUs or a 100% check take more — the quote says so upfront.
No travel fees
Inspector travel inside covered regions is included, not billed back to you.
No weekend surcharges
A Saturday at the factory costs the same as a Tuesday.
Quote from your spec
Send the lot size, style count and test requirements to inquiry@utsinspection.com — the quote comes back with the exact scope in writing.
Where we inspect
Thirteen provinces in China and thirteen countries across Asia. The jewelry clusters in Guangdong, Zhejiang, Fujian and Shandong all sit inside the standard 48-hour coverage.
An accredited inspection body, not a freelancer platform
The certificate on the left is the real document. The registration number on it is CNAS IB0642.
ISO/IEC 17020 since 2016
CNAS-accredited as an inspection body — the standard written for companies that inspect for a living.
ISO 9001:2015
A certified quality management system behind every booking, report and escalation.
Full-time inspectors
University-degree engineers employed by UTS, with GPS check-in at every factory visit — not contractors hired by the day.
Brands that buy third-party quality control
Fashion, retail and consumer brands across the US and Europe book inspections with UTS.

Questions buyers ask before booking
How much does a jewelry inspection cost?
Pricing is per man-day and depends on your lot size, the number of styles and the tests you need. There are no travel fees and no weekend surcharges. Send your spec to inquiry@utsinspection.com and the quote comes back with the exact scope in writing.
How fast can an inspector reach the factory?
Within 48 hours of booking, across 13 provinces in China. We also cover 13 countries in Asia for orders outside China.
When do I get the result and the report?
You hear the result — pass, fail or hold — the same day, before the inspector leaves the site. The full PDF report with photos follows within 24 hours.
What happens if the goods fail?
The report documents every failure with photos and classified counts, and the release decision stays with you. Most buyers ask the factory to rework the affected units, then book a re-inspection on the reworked quantity.
Do you test gold or silver purity?
On site we verify stamps, markings, weight and workmanship. Chemical composition — purity, lead, cadmium, nickel release — is a laboratory job. We draw and seal the samples on site and coordinate the lab test so the result is documented.
How many pieces do you check?
Sampling follows ANSI/ASQC Z1.4 (ISO 2859-1), default General Level II, with Critical 0, Major 2.5 and Minor 4.0 acceptance limits. For high-value lots you can book a 100% full inspection where every piece is examined.
Can you check barcodes and packaging for retail or Amazon?
Yes. Every unit gets a barcode scan, and we check hang tags, polybags, pouches, boxes, the style assortment per PO and run a carton drop test matched to the carton weight.
What do you need from me to book?
Your PO details, a spec sheet with tolerances, approved sample photos, the packing list and carton count, and your barcode and label files. Scope and price are confirmed in writing before the visit.
Send your spec. Get a quote and an inspection date.
Email the PO and spec sheet, or call the team directly. You can also book straight through the order portal.
