  1. What is an 'AUDITED' Glass Plant, and how can it be of benefit to me??


  2. At GLASSPLANT CONFIDENTIAL we know the difficulties western Food & Beverage manufacturers face when trying to determine which plants in Asia would be the most suitable to manufacture their bottles and jars. We attempt to make that process as smooth as possible by providing a one-stop shop that will save you many hours of non-productive searching and investigation. We achieve this in many ways by:
    1. Providing a comprehensive 'Directory of Glass-Plants and Traders' based in China, Taiwan, Asia and the Middle East, and accumulating as much information as possible on these plants so as to provide the best possible matchup with the types of containers your manufacturing plant requires.
    2. Providing a large range of technical documents and quality-related information on the GPC website that will provide you with the tools to help make informed decisions when selecting glass-plants or traders as your potential suppliers.
    3. Undertaking AUDITS of selected plants to assess their quality systems, and their ability to manufacture the different styles of glass containers filled by western food & beverage manufacturers.


    GLASSPLANT CONFIDENTIAL has been auditing glass-manufacturing plants throughout Asia and the Middle East through its sister company Glass Identification Services, since 1998. Many plants have been audited multiple times. The Auditing process provides valuable information on the abilities of a plant to manufacture certain styles of containers. More importantly, auditors are well versed in international BEST PRACTICE principles, and are therefore able to identify areas within the glass-manufacturing plants that require improvement or modification when manufacturing ware for Western customers.

    In most instances, the improvements needed by the Asian glass-plants will simply be the requirement to introduce additional and more stringent testing procedures, to ensure the ware is manufactured to Western standards. For glass-plants that have been AUDITED by GPC, a 'SUMMARY OF OPERATIONS' report is available that provides western customers with a detailed overview of the plants operations. PLUS, as a bonus, GPC has included a "LIST OF ADDITIONAL QUALITY REQUIREMENTS" for the audited plant. This list is provided in a separate section at the end of the 'Summary of Operations' report, and can simply be removed and provided to the Glass Manufacturing Plant as part of any manufacturing agreement. The 'List of Additional Quality Requirements' will be a valuable tool to ensuring the plant produces the best possible quality for your chosen container.

  3. Tell me more about the "List of Additional Quality Requirements" that GPC has included at the back of its 'Summary of Operations' Reports.


  4. A number of the Glass-Plants listed in the 'Directory of Glass Manufacturers & Traders' have been 'AUDITED' by GLASSPLANT CONFIDENTIAL. This means they have been visited by GPC, and a comprehensive audit of their facilities has been undertaken. Where such audits have been undertaken, GPC has produced a "Summary of Operations" report that provides a detailed 'overview' of the plant, and more importantly, provides a 'List of Additional Quality Requirements' that will need to be in place at the Plant when manufacturing ware for western customers. The 'List of Additional Quality Requirements' is provided in a separate section at the end of the "Summary of Operations" reports, so that it can be easily removed or copied, and provided to the Glass-Plant to form part of any manufacturing contract.

    The 'List of Additional Quality Requirements' will vary from plant-to-plant, and has already been discussed with the Plants at the time of auditing. Therefore there will be no surprises when YOU, as a western purchaser, hand over the 'List' when completing a purchase agreement. The 'List' will be an IMPORTANT contributor to the final quality of the glass containers being manufactured for you. It will also assist you in being more knowledgeable about the glass-manufacturing process in the eyes of the Asian manufacturer.

    For those businesses serious about QUALITY and serious about getting the most from the glass-plant they choose to work with, it is strongly recommended they take advantage of the "Summary of Operations" reports if available for their chosen plant. 'VIP' and 'Silver' members will have access to a number of free "Summary of Operations" reports as part of their annual membership. Additional reports will be available at significantly discounted rates for 'VIP' and 'Silver' members.

    New "Summary of Operations" reports will be added to the Directory regularly, as new plants are audited, and existing plants upgrade their status to "Audited Plant".




  5. How do I know which Glass Plants are 'AUDITED' plants??

  6. Plants that have been audited by GLASSPLANT CONFIDENTIAL will be easy to find in the 'DIRECTORY of GLASS MANUFACTURERS and TRADERS'. They will have a prominent "AUDITED PLANT" banner attached to their Directory Listing, with a link that will allow you to access their 'Summary of Operations' report.




  7. Should I choose an 'Audited Glass Plant' over one that has not been audited??


  8. GLASSPLANT CONFIDENTIAL is here to help YOU find the BEST plant possible to manufacture your glass containers. You will need to weigh up the 'pro's & con's' of each plant that is capable of manufacturing your vessels. However different companies will have different priorities. Some will be driven by price, others might prefer a plant that can manufacture low quantities in a given production-run. Colours, palletising options, and many more considerations may influence your final decision. There is no 'one-plant-fits-all' formula. The GPC Website will allow you to select a number of potential suppliers, and these can be narrowed down once you determine which of those best suits your purchasing requirements.

    If any of your selected glass-plants are not 'Audited' plants, it does not mean that they are not capable of manufacturing your glass vessels. Given the large number of plants throughout Asia, it is simply not practical to audit them all. However each year GPC will continue to audit a range of plants that have the potential to manufacture ware for Western companies, and these will be added to the website on an ongoing basis. Some of these plants will already be exporting to Western countries.

    So - What advantages do the AUDITED PLANTS have? Firstly, the Audited Plants have been visited by GPC auditors - some multiple times - and their quality systems and procedures have been scrutinised. This means that:
    1. The plants operations have been audited and documented. Quality systems have been compared to some of the leading glass-manufacturers internationally. A summary-report has been taken from the comprehensive audit report - this is called the "Summary of Operations", and is available to all members of the GPC Website. This document provides an overview of the plants operations, and will provide you with 'inside' knowledge not available from other sources - a 'confidential' insight into the workings of the plant, and an important tool when assessing potential suppliers!
    2. A detailed report summarising areas where procedures and quality checks fall short of those required to manufacture glass containers for Western Customers is also provided. These additional requirements are clearly itemised into an 'easy-to-print' document referred to as the "List of Additional Quality Requirements". The glass-plant will readily understand these additional quality-requirements, and will have no problems implementing them when manufacturing your glass containers. The "List of Additional Quality Requirements" forms part of the "Summary of Operations" report, and is an essential aid for those serious about quality.
    3. If you choose to have your glass containers manufactured at one of the Audited Plants, the above information will allow you to enter into a manufacturing agreement with confidence! You will know the additional quality procedures the glass-plant must put in place to manufacture your ware, and you will appear more knowledgeable in the eyes of the plant.




  9. The Plant I have chosen to manufacture my glass-containers has not been Audited. How can I be sure that they will produce my ware to Western Quality Standards??


  10. One of the great advantages of the GLASSPLANT CONFIDENTIAL team is that they fully understand the Asian and Middle-Eastern glass-manufacturing environments. In China and Asia in particular, it is not uncommon for glass-plants to have two or even three levels of quality!! You do not want your glass containers manufactured at the lowest level!!

    Therefore, as a member of the GPC Website, you should take advantage of the many 'Specifications' and 'Quality' documents and articles that are available! These will provide you with valuable information that you can pass on to your 'non-audited' plant, and request that they manufacture ware to those quality requirements. Whilst the precise quality-procedures of the non-audited plant might be unknown, you will have more confidence in your decision (and more confidence in the glass-plant) if you know they are manufacturing your glass containers to the GPC Specifications. As a minimum, you should print off the following documents, and pass them to your glass-manufacturer as YOUR required quality standards:

    • Specifications for Bottles & Jars - PART 1
    • Specifications for Bottles & Jars - PART 2
    • Specifications for Bottles & Jars - PART 3


    Note: For convenience, the above documents are available as a single easy-to-read document titled "Specifications for Bottles & Jars - PART 4". Click HERE to view the Specification Documents.

    GPC Members should also read the 'Quality' documents and articles available on the website, as many of these will highlight general issues that might occur with Asian-manufactured glass. If you have any concerns, make a note of any issues you think might be relevant to the manufacture of your glass vessels, and ask your manufacturer about these. If they are aware of your concerns, they will make an effort to address them. You can also contact the GPC 'Help-Hotline' if you have any technical queries (available to VIP and Silver Members).

    Many companies prefer to have a representative at the glass-plant when their vessels are being manufactured. They may arrange for their own quality representative to be present, or engage the services of GLASSPLANT CONFIDENTIAL to monitor the production on their behalf. Alternatively, the company may request GPC undertake an Audit of the plant prior to commencement of production. Further information on GPC Auditing and Monitoring services can be found HERE.




  11. My Company has been sourcing glass containers from Asia for some time. Is it too late to have our supplier audited?


  12. GLASSPLANT CONFIDENTIAL regularly undertakes Auditing and Monitoring exercises on behalf of Food and Beverage manufacturers. Many audits have been undertaken in plants that western companies have been sourcing from for some time. Such exercises may be requested for a range of reasons:
    • The overall quality of the glass vessels has reduced over time, or a significant quality issue occurred that required the company to take action to ensure it was not repeated.
    • The company has a brand new vessel which is being manufactured for the first time. They wish to ensure all required quality procedures are in place to ensure the vessels are manufactured to the required quality standards
    • Glass vessels have been manufactured to acceptable quality standards, however the company wants to ensure ongoing quality is maintained by undertaking periodic audits at the glass manufacturing facility.


    To request further information or pricing for an Audit or Monitoring exercise, please submit your request on the GPC form 'AUDITING and MONITORING Services'.
