IMS product codes look like line noise — `B702TH24.5M`, `B682TCH26.5E`, `B702TFH24NT` — but every character is doing a job, and once you can read one you can tell at a glance whether a basket will fit your machine and what dose it's built for. This is the code structure in IMS's own terms, then every code in our database with a link to its verified spec.

## Reading a code, character by character

Take `B702TCH26E`:

## The series decide fitment — sizes don't

The single most useful thing the code tells you is the series, because IMS assigns series to *brands*, not to nominal portafilter sizes. A Gaggia and a Rancilio are both "58mm" machines, yet IMS puts Gaggia in B68 and Rancilio in B70. Buy by series, not by the number on your portafilter.

- **B70** — Ø70mm border. IMS lists this series for E61 and other 58/58.4mm-tamper machines — La Marzocco, Rancilio, Lelit, Rocket, ECM and the Breville Oracle.

- **B68** — Ø68mm border. IMS heads this series "CARIMALI, GAGGIA, LA CIMBALI" — this is the Gaggia series, not B70.

- **B64** — Ø64mm border, made "for tamper 57" — Lelit's LELIT57 machines.

- **B62.5** — Ø62.5mm border, Ø54mm body, Ø53mm tamper — the 54mm Breville/Sage format. Note the format is named after the body, not the tamper.

- **B60** — Ø60mm border, Ø52mm body — post-millennium La Pavoni levers.

## How we verify

The code structure above is quoted from IMS's own filter code guide; every basket's dimensions come from its IMS product page, read firsthand and dated on the entry. See [how we verify compatibility](https://espressofit.com/methodology/), or use the [parts finder](https://espressofit.com/finder/) to jump straight to the baskets confirmed to fit your machine.
