24/410 Vs 28/410: Which Neck Finish
24/410 is a 24 mm neck with a 410 thread — the default for 250–500 ml bottles and most lotion pumps. 28/410 is 28 mm, used on 500–750 ml bottles with bigger pumps. A 28/410 pump will not fit a 24/410 bottle, and a 24/410 pump on a 24/415 neck threads on but leaks.
| 24/410 | 28/410 | |
|---|---|---|
| Neck diameter | 24 mm | 28 mm |
| Thread | 410 profile | 410 profile |
| Typical bottle | 250, 300, 500 ml | 500, 750 ml |
| Typical pump | 1.2–2.0 ml lotion | 2.0 ml+ heavy-duty |
| Wall needed | 0.55 mm at shoulder | 0.65 mm at shoulder |
| Where it fails | Using a 415 thread bottle | Under-thickness at the shoulder |

Why the Number Is Two Numbers
24 is the diameter in millimetres; 410 is the thread profile (T dimension 4 mm, E 1.0 mm). Two bottles can both be '24 mm' and still not interchange if the thread differs.
How to Confirm Before Ordering
Send the closure you intend to use, or a caliper reading of T, E and H. We test the pump on the bottle before quoting, rather than assuming the neck is standard.
What T, E and H Mean
T is thread height, E is thread pitch, H is the neck height to the sealing surface.
Compatibility, Packing and Tolerance
Closures That Fit
Send the neck finish and we match a closure from the same plant: disc-top and flip-top caps, lotion and foam pumps, mist sprayers and droppers. Closures are fitted and tested on the bottle before packing, which is where most leaks originate.
Packing and Freight
Carton quantity, carton dimensions and gross weight are quoted with the unit price. FOB Shantou is the default term; EXW and CIF are quoted on request. Payment is 30 % deposit, 70 % against the bill of lading.
Tolerance
Dimensions hold to ± 1.5 % and weight to ± 1 g against the approved drawing. Anything outside that range is remade, not discounted.
Decoration Options and What They Cost in MOQ
Silkscreen in one to four colours starts at 1,000 pcs and adds about five days; the plate is a one-off, which is why it does not repeat on a reorder. Labels are lower in unit cost for multi-colour artwork and allow short runs. Hot stamp, spray coat and metallising start at 3,000 pcs because the line set-up is heavier and the reject rate is higher.
Decoration also decides the recycling story. A paper label with a wash-off adhesive keeps a PET bottle in the PET stream; a full-body sleeve does not. If the pack carries a recyclability claim, the decoration is part of the claim, not a design detail.
Sampling and Approval
A sample from an existing mould takes 7 days and comes from the production tool, not a showroom piece. For a new shape, tooling takes 15–20 days before sampling. We ship the sample with the drawing it was made to, so the approval is against a number rather than a photograph.
If the formula contains alcohol, a high level of essential oil or a particulate, say so at sample stage — the compatibility test runs four weeks and it costs less to find a problem then than in a container.
How We Quote and Ship
Send capacity, neck, quantity and the closure you intend to use. We reply within one business day with unit price, packing data (pcs per carton, carton size, gross weight) and lead time — the packing data is what your freight forwarder needs, so it is quoted with the price rather than after.
Production is 25–35 days after sample approval on existing moulds, 15–20 days longer if a new mould is needed. Payment is 30 % deposit and 70 % against the bill of lading; FOB Shantou is the default term, EXW and CIF on request.
What We Do Not Do
We do not fill, formulate or design labels, and we do not hot-fill in standard PET above about 60 °C. We hold ISO 9001:2015 (PCC85724Q01277R1S), RoHS reports for PE and PET and an EU 10/2011 migration test — and we do not claim FDA, REACH or GRS certification we do not hold.
Frequently Asked
What does 24/410 mean?
24 mm neck diameter with a 410 thread profile; the 410 is not a diameter.
Will a 28/410 cap fit a 24/410 bottle?
No — 4 mm larger, it will not seal.
Can I use a 24/410 pump on a 500 ml bottle?
Yes if the wall is at least 0.55 mm at the shoulder.
What is 24/415?
Same diameter, different thread height. A 410 closure threads on and leaks — the most common mismatch.
How do I measure a neck?
Caliper T, E and H, or send a sample; a photo is not enough.
