Each crate had a unique "series" of items. Items in each crate were classified as Rare, Very Rare, Import, Exotic, and Black Market.
They could've been unlocked with keys, which were available for sale in the "Manage Inventory" and "Crate Unlock" menus. Unlocking a crate revealed a random exclusive item. There was also a chance of acquiring a certified or painted variant of said item.
Alternatively crates could've also been opened using decryptors.
The following table shows an example of drop percentage when a new crate was released.
|5%||Phaseout||PCC, Turbo, Nitro, Overdrive|
Within a "category", crates had equal drop odds. So Velocity and Accelerator effectively dropped 5% of the time, while PCC dropped 1.25% of the time (as it shared with 3 others).
Crates could've also been traded with other players.
- Rare Item: 55%
- Very Rare Item: 28%
- Import Item: 12%
- Exotic Item: 4%
- Black Market Item: 1%
- Chance of receiving Painted attribute: 25%
- Chance of receiving Certified attribute: 25%
The Crate system used a three-step process. When you opened a Crate with a Key or Decryptor, the system first determined what rarity level to choose from -- Rare, Very Rare, Import, Exotic or Black Market -- based on the percentages listed above. Next, the system determined which item within that rarity group was dropped. If you received an Import-level Customization Item from the Impact Crate, for example, each of the three Import items in the Impact Crate had an equal chance of dropping. Finally, the system determined if the item would've dropped with Painted and/or Certified attributes.
NOTE: These drop rates had been the same since the Crates and Keys system launched in September 2016. Every Crate and Crate Series in Rocket League were subject to these rates, whether it was the retired Champions Series Crates or the Crate that was released this summer.

All four Champion crates were officially retired on July 5, 2017.
Black Market items
Items listed here had a 1% chance of being found in crates, they could not have been obtained via Trading.
- Main article: Decal
Black Market decals are unique in that they were once shown in the preview as an Octane battle-car partially covered by a purple hexagon-motif fabric. These decals were dubbed "Mystery Universal Decal" in the preview, which means that the Black Market decals are applicable to all Battle-Cars. Since the Patch v1.41, they can be previewed normally and are no longer dubbed “Mystery Universal Decal”.
