Quality control
is one of the services most in demand by buyers in
China.
This is due to the lack of quality standards as
different qualities can often be found in the same
production batch.
The main causes are due to the high mobility of
personnel, many companies will exchange the staff
according to the needs of the moment so there is a
lack of skilled people.
The reduction of the profit in the production
activities in China pushes Chinese companies to look
for both sub-contractors and cheaper raw materials
hence poor quality.
Sometimes it happens that a production is damaged
due to unsuitable packaging, other times due to the
fact that materials are still wet or not dried and
packed with the consequent creation of mold during
transportation, other times heavy goods are loaded
on top of lighter goods with consequent damage to
the underlying commodity.
There are thousands of problems caused from very
elementary rules which factories do not follow
because they are not checked from a company like us.
Our experience tells us that there must be a very
vigilant Quality Control: The monitoring should be
carried at all times, during all phases of work and
not just at the beginning.
However, before undertaking business collaboration
it
would be advisable to make certain verifications in
regards to the furnisher.
Several factors can be learnt from a visit. Visiting
offices and production sites is important but it is
even more important to evaluate real potential as
well as good intentions.
More and more factories just disappear into thin
air; perhaps after having participated to the fairs,
having given competitive prices, after having
received a down payment. We will be present on the
place of production thus avoiding such problems.
In summary our services include:
Quality control of products
Packaging, storage, loading and transport
Monitoring compliance with regulatory requirements
Inform in advance about production problems and delays in delivery
Ensure that contractual obligations are met: specifications, packaging, marking and delivery
Identify problems before delivery

Factory Audit
An audit and evaluation performed according to the
standard factory SA 8000 and supplemented as
necessary by specific customer requirements.
All the important factors are taken into account
such as quality system procedures, production
capacity, the use of child labor, the staff
facilities, hygiene ... etc.
The audit allows you to evaluate a supplier from the
productive and socio-economic development.
Sampling
When possible a sample should be made even before
the conclusion of the contract in order to have a
clear idea of the level of quality and
specifications required.
The evaluation of the sample is the first step in
order to avoid future mistakes, misinterpretations
and misunderstandings with the supplier.
Pre-production Control
The inspection takes place in the initial part of
the production. Its purpose is ensuring that all
components and materials used are in accordance with
the sample and with the specifications laid down in
the contract in order to correct any problems before
production.
In this inspection we can also check the packaging
and, naturally, the quality of the material even if
it is not yet printed.
Control during production
The production is inspected when at least 25% of the
order has been completed.
More generally, inspection allows direct control of
the site to ensure that quality is maintained at
every stage of production and make sure they meet
the production time and delivery.
Final inspection sample
It is performed when at least 80% of the order is
produced or packaged.
The samples are chosen at random, according to AQL
sampling.
Inspection of loading
The inspector, making sure that the products are the
right ones, checks the quality and quantity of the
goods. In addition, prior to loading, this
inspection ensures that the products are related to
AQL sampling standards.
Subsequently the loading is supervised to ensure
that the container is in good conditions and that
the whole is loaded in accordance with the amount
specified in the P/O. Particular attention is paid
to the load sequence in order to avoid heavy items
damaging the lighter ones.
Inspections based on AQL (acceptable quality
levels)
Inspectors use the ISO 2859 tables (also known as
AQL tables) to measure acceptable levels of quality.
These tables are a U.S. standard with equivalents in
all organizations for national and international
standards (ANSI / ASQC Z1.4, ISO 2859, NF06-022, BS
6001, DIN 40080).
How to determine the sample size and the
acceptance number?
It establishes the type of inspection , locates the
production batch, and selects the AQL (usually
1.5%), in this way it will be possible to have the
sample to be examined and the number of acceptance
maximum of defective parts.
Example:
for a hypothetical inspection of a consignment of
5,000 units, with an acceptable quality level of
1.5%, Table B indicates that the sample must consist
of 200 units.
The number of corresponding acceptance is 8.
Therefore a maximum of 8 pieces may be defective.
What does it mean in practice?
If the number of defective units is greater than 8,
the batch must be discarded.
When the match is accepted, it is understood that
contains at most 1.5% of the faulty units (with a
risk of error of less than 5%).
What to do with the defective items, or
discarded?
Defective units identified during an inspection can
be discarded, repaired or replaced.
You can also choose to sell discarded lots at a
discounted price or ask for a discount hypothetical
percentage of defective items.
For a demonstration see Tables here.
