Glass jars for a 124,740-jar order, checked against the buyer’s approved samples before shipment
A food manufacturer in Morocco bought 350 g glass jars from a maker in China. It first tested pre-production samples on its own production line and approved them in writing. Sinospect kept those samples as the physical reference, measured nine production jars against them and arranged a 500-jar inspection of the two containers, 124,740 jars, which passed on 23 September 2026.
Send your specification or quotationSinospect’s role
The buyer ordered directly from the maker on FOB terms. Sinospect received the maker’s pre-production samples on 22 July and sent them to the buyer for its line trial, kept three as the reference once the buyer had approved them, measured nine jars from mass production and organised the inspection at the maker’s warehouse.
What was supplied or controlled
350 g glass jars in two orders of 62,370 jars each, packed on pallets for two containers: 124,740 jars, checked for weight and wall thickness against the approved samples.
The recorded sequence
Approve the samples
The buyer tests pre-production jars on its own line and approves them in writing on 10 September.
Measure the production
Nine mass-production jars weighed and gauged at seven points against the three retained samples.
Inspect before shipment
500 jars sampled from 124,740 at the maker’s warehouse on 23 September: passed.
Checks before shipment
On 15 September Sinospect weighed the three retained samples and nine jars from mass production, and measured each wall at seven points (four on the body, then the base, the shoulder and the heel) with an ultrasonic thickness gauge. The production jars weighed 285.0 to 290.4 g, on average 1.6 % lighter than the approved samples (289.4 to 292.2 g). Both sets ran above the 270 ± 13 g on the maker’s drawing, meaning more glass rather than less; the buyer had made the approved samples, not the drawing, the reference. Every wall reading cleared the drawing’s minimum for its position, the thinnest at 2.39 mm on the body against 1.3 mm required. The buyer still wanted the packed goods checked. At AQL general inspection level II, a lot of 124,740 calls for a sample of 500 jars; the maker offered 200 in one day, and the buyer held to 500.
The evidence
The buyer’s written approval of the samples after its line trial, dated 10 September 2026; the three retained samples; the measurement sheet with the weight and seven wall readings of each of twelve jars; and photographs of the measurements.
Recorded result
The inspection of 23 September at the maker’s warehouse passed. The buyer, which books its own freight on FOB terms, had a recorded result for both containers before they left the maker.
What this means for your order
An approved sample is only a reference if someone keeps it and measures against it. Agree which samples are the reference, which dimensions are checked and how many pieces are inspected before production finishes. Send the product drawing and your sample requirements, and we will set the comparison points for your order.
