Product information on this site
Pages describe what we develop and manufacture. Figures such as minimum order quantities, production capacity and lead times are indicative and are confirmed in a written quotation for your specific project — the page is not the offer.
Photographs may show packaging produced for other clients, marked as client packing. Those brands are not affiliated with us and the images are shown only to illustrate capability.
Quotations
A quotation is valid for the period stated on it. Prices depend on formula, fill volume, packaging and order quantity, and are only fixed once these are agreed in writing.
Samples
Development samples are made to the brief you provide. Sample lead time and any sample charge are stated before work begins. Samples are for evaluation and are not for resale.
Intellectual property
The text, layout and images on this site belong to us or are used with permission. You may reference our pages and quote short passages with attribution. You may not republish the site wholesale or present our content as your own.
Formula ownership on client projects is set out in the project agreement, not on this page. Where a project is agreed as exclusive, that exclusivity is written into the contract before development starts.
What we do not promise
We do not guarantee that a formula will pass regulatory review in your market, that a packaging supplier will hold a given lead time, or that a product will achieve a particular commercial result. We do commit to testing what we claim and to telling you what we actually measured.
Limitation of liability
This site is provided as information. To the extent permitted by law, we are not liable for losses arising from reliance on the site alone. Liability for goods supplied is governed by the contract under which they are supplied.
Governing law
These terms are governed by the laws of the People’s Republic of China. Disputes are subject to the courts of Zhongshan, Guangdong.
