200 vs 202 Can Ends Explained: B2B Sourcing Guide
Get the end diameter wrong and your seamer will jam, or worse, you will get leaky double seams. Size 202 and size 200 ends look similar on a spec sheet, but they are not interchangeable. The 2.5 mm gap between them decides whether the lid fits your can body, your chuck tooling, and your filling line speed.
We focus on aluminum beverage cans and easy-open ends. Day to day, we help buyers match the right end diameter to their body profile, seamer chuck, and filling line. Here is what you need to know when choosing between size 200 and size 202 ends.
1.What is the primary physical difference when explaining 200 vs 202 can ends?
The number refers to the end shell diameter. Size 202 is 52.5 mm. Size 200 is 50.0 mm. That 2.5 mm gap is the whole story.
Size 202 is the default for standard 355 ml and 500 ml cans, plus sleek 330 ml and 355 ml bodies. Size 200 is built for slim 250 ml cans, the kind you see on energy drinks, cold brew coffee, and small functional tonics. The smaller neck uses less metal and gives the can a taller, narrower look on the shelf.
One mistake we see often: a brand orders 202 ends for a slim 250 ml body because "202 is the standard," then discovers the seamer chuck will not close properly. If you are not sure, send us the body neck drawing before you place the order.
2.How do material-saving lightweight profiles optimize bulk contracts for both sizes?
You can move from old-style B64 ends to CDL ends on either size. CDL uses roughly 10% less aluminum sheet without changing the neck dimensions or weakening the buckle.
That matters when you are buying metal indexed to the LME. A brewery or soft drink bottler running millions of 202 ends will feel the saving immediately. On size 200, CDL still has to hold the same carbonation pressure and axial load, so the gauge reduction is calibrated carefully.
3.200 vs 202 Technical Sourcing Reference & Compatibility Matrix
This table matches end size to body type, tab style, pressure rating, and the usual MOQ:
| Nominal Lid Sizing Profile | Physical Diameter Finish | Compatible Can Body Silhouettes | Available Tab Mechanisms | Laboratory Buckle Rating | Standard MOQ per SKU |
|---|---|---|---|---|---|
| Size 202 End Profile | 52.5 mm | Standard (355 ml / 500 ml) Sleek (330 ml / 355 ml) |
SOT (Stay-on-Tab), RPT (Ring Pull), Full Aperture (FA) | 90 – 102 PSI | 1 Full 40HQ Container Load |
| Size 200 End Profile | 50.0 mm | Slim Profiles (250 ml) | RPT (Ring Pull Tab), Specialized SOT Matrix | 85 – 90 PSI | 1 Full 40HQ Container Load |
*(Note: Our high-speed lines make aluminum beverage can ends and matching bodies. We run separate lines for non-beverage products like milk powder peel-off ends and tinplate easy open lids.)*
4.How do internal lacquer linings complement 200 and 202 ends across global trade borders?
The lining rules are the same for both sizes. What changes is the market. Russia, Ghana, and similar price-sensitive markets usually accept Epoxy-Phenolic linings because they cost less. North America and the EU require BPA-NI, or BPA Non-Intent, lacquers.
Acidic drinks and carbonation put electrochemical stress on the metal, especially around the rivet and score. Before you release a bulk order, ask for SGS migration reports and check that the plant holds ISO 9001 and FSSC 22000. Those two documents are the fastest way to confirm the lining will survive the shipment and pass customs.
5.Custom colors, laser logos, and under-tab QR codes
Standard container-load orders open up the tooling menu. You can order custom lid colors, custom tab colors, laser-etched logos on the tab, and hidden under-tab QR codes. Both size 200 and 202 ends can take these finishes.
The QR code sits under the SOT lever, so shoppers cannot see it until the can is open. After opening, they can scan it for loyalty points, lottery entries, or batch tracing. It is also a simple way to make gray-market copies harder to pass off.

Frequently Asked Questions
What is the primary physical difference when explaining 200 vs 202 can ends?
It is the diameter. Size 202 is 52.5 mm and fits standard and sleek cans. Size 200 is 50.0 mm and fits slim 250 ml cans.
Can beverage brands freely combine custom colors and tracking tools across both 200 and 202 end sizes?
Yes. You can mix lid colors, tab colors, laser-etched logos, and under-tab QR codes on both size 200 and size 202 ends.
Which aluminum can body silhouettes does each end size fit?
Size 202 fits standard 355 ml and 500 ml cans, plus sleek 330 ml and 355 ml cans. Size 200 fits slim 250 ml cans, common in energy drinks, cold brew coffee, and functional tonics.
How do lining compliance rules differ across export markets for 200 and 202 ends?
They do not differ by end size. Epoxy-Phenolic linings are accepted in price-sensitive markets like Russia and Ghana. North America and the EU require BPA-NI lacquers backed by independent SGS migration reports.
