You can get AADC rates for pieces that are not in AADC trays
Myth: You can only get an AADC rate (or Machinable AADC rate) when pieces are in an AADC tray of 150 pieces or more.FACT: A 3-Digit Origin tray can also get an AADC or Machinable AADC rate

Quick Service Guide 240b: Standard Mail Machinable Letters
3-Digit Origin/Entry
Trays: Optional, trays may be prepared for each origin 3-digit tray; one less-than-full tray permitted.
Labels: For Line 1, use L002, Column A, for destination facility. For Line 2, use "STD LTR 3D MACH."
Rate: Machinable AADC
DMM 243.5.4.1
Instead of preparing overflow trays, mailers may include pieces in the mixed AADC trays. Pieces placed in a mixed AADC tray in lieu of an AADC overflow tray are eligible for the AADC rate.
5.4 Machinable Rate Application
Machinable letters are subject only to AADC and mixed AADC rates.
DMM 243.5.4
5.4.1 AADC Rate
The AADC rate applies to qualifying letter-size machinable pieces (see 201.1.0, Physical Standards for Machinable Letters and Cards) placed in origin/entry 3-digit trays, to quantities of 150 or more pieces prepared in AADC trays for a single AADC, and to pieces placed in mixed AADC trays in lieu of overflow AADC trays.
DMM 243.5.4.1 tells you there are three ways to get the Machinable AADC rates:
1. A 3 digit origin tray
2. A 150-piece AADC tray
3. A MAADC tray in lieu of an Overflow AADC tray.

DMM 243.7.3
c. Groups of fewer than 150 pieces in origin/entry 3-digit/scheme trays and groups of 150 or more pieces in AADC trays qualify for the AADC rate. Pieces placed in mixed AADC trays under 245.7.5 in lieu of AADC overflow trays also are eligible for AADC rates (see 245.7.5).
Once again, there are three ways to get the AADC rates:
3 Digit Origin tray with fewer than 150 pieces
AADC tray of 150 or more pieces
Mixed AADC tray in lieu of an AADC overflow tray.

3-Digit/Scheme
Trays: Required, at least 150 pieces to same 3-digit/scheme destination; only one overflow tray permitted per destination.
Optional: One less-than-full tray may be prepared for any remaining pieces for each 3-digit/scheme of SCF serving post office where mail is verified.Barcoded Labels: For Line 1, use L002, Column B, for destination facility.
Rate: 3-Digit or AADC
AADC rate for any 3-digit/scheme tray for the origin SCF area containing fewer than 150 pieces.
Nonmachinable Standard Class Letters
DMM 243.5.5.3
5.5.3 ADC Rate
The ADC rate applies to letter-size pieces subject to the nonmachinable rates (see 5.5) placed in 3-digit origin/entry trays and to pieces prepared in quantities of 150 or more for an ADC and presented in ADC trays under 245.5.0.
Quick Service Guide 240a: Standard Mail Nonmachinable Letters
Optional: Tray may be prepared for any remaining bundles for each origin 3-digit ZIP Code prefix.
Rate: Nonmachinable 3-Digit or Nonmachinable ADC
Nonmachinable ADC rate for pieces placed in 3-digit origin/entry tray.
First Class Automation Letters

3-Digit/Scheme1
Trays: Required, 150 pieces to same 3-digit/scheme destination; bundling not permitted; only one overflow tray permitted per destination.2
Exception: After all full trays are prepared, one less-than-full tray must be prepared for any remaining pieces for each 3-digit of SCF serving post office where mail is verified.
Rate: 3-Digit or AADC
AADC rate for any 3-digit/scheme tray for the origin SCF area containing fewer than 150 pieces.
DMM 233.5.3
c. Groups of fewer than 150 pieces in origin 3-digit/scheme trays and all pieces in AADC trays qualify for the AADC rate. Pieces placed in mixed AADC trays in lieu of AADC overflow trays under 235.6.6 are eligible for the AADC rates.
