Your customer says a pint and means one of two volumes almost 100 ml apart. That is the single most expensive ambiguity in this size, and naming the system removes it.
The 3 Volumes People Call a Pint
| Name | Volume | Where your buyer uses it |
|---|---|---|
| US pint | 473.18 ml, 16 US fluid ounces. | United States and Canadian retail, and your mason jars. |
| Imperial pint | 568.26 ml, 20 imperial fluid ounces. | United Kingdom, for draught and bottled drinks. |
| 16 imperial fluid ounces | 454.61 ml. | Rarely a format, often a conversion mistake in your file. |
Why the Gap Reaches Your Label Claim
Your imperial pint holds nearly 100 ml more than your US one. A product filled to a US pint and sold as a pint in the UK under-delivers against what your customer expects.
That is a labelling exposure rather than a production annoyance. Write the volume in millilitres on your specification and let the pint stay a marketing word.
Where 473 ml Sits Against 500 ml
Your nearest metric neighbour is 500 ml, at 16.9 US fluid ounces. The two get swapped in conversation because the labels look similar, and your filler treats them as different jobs.
Pick on your fill volume rather than on the name. SGSBOTTLE lists both formats with brimful and nominal capacity for glass from 14 lines in Shandong and Xuzhou, so your comparison uses measured numbers.
473 ml and 500 ml are different jobs for your filler. SGSBOTTLE runs 14 lines in Shandong and Xuzhou.
What the Format Gives You in Tooling
Your 16 oz jar is one of the best-supported sizes in North America, so stock shapes exist and your launch can run without a mould.
That support extends to closures. Your lug and continuous thread finishes at this capacity are widely available, and SGSBOTTLE issues the finish designation with tolerances on the drawing for glass from the 14 lines in Shandong and Xuzhou.
What Your Jar Actually Holds
Your 16 oz jar holds more than 473 ml to the brim, because headspace has to exist for your closure, your product expansion and your filling method.
Ask for the brimful figure with your drawing. A hot-filled or vacuum-sealed jar needs that number to set your fill point, and the size on your carton does not supply it.
What Goes on Your Enquiry
Your fill in ml and oz with the ounce system named, your product and fill temperature, your closure, and your annual volume. SGSBOTTLE comes back with the stock formats, their brimful capacity and the finish each carries.
