Parcels are nonmachinable if they meet any of the criteria in 401.2.3. Parcel Post pieces meeting any of the criteria in 401.2.3 are subject to a nonmachinable surcharge in addition to postage.
Machinable parcels must bear the correct readable UCC/EAN Code 128 barcode under 708.5.0.

Package Services barcodes may be combined with Delivery Confirmation or Signature Confirmation and insurance barcode.
Standard Mail barcodes may be combined with electronic Delivery Confirmation and insurance.
Standard Mail and Package Services barcodes must be prepared with the address and barcode placed squarely onto the largest surface area of the parcel except when the shape and contents require specific orientation for stability during processing. The barcode should be placed immediately adjacent to the delivery address and no closer than 1/2 inch from the edge of the parcel.
Acceptable Container (601.3.0)
Use sturdy materials to withstand handling.
Size must be adequate to contain items and provide space for cushioning material:
- Paperboard boxes for easy and average loads up to 10 pounds.
- Metal-stayed paperboard boxes for easy and average loads up to 20 pounds.
- Soft goods in paper or plastic bags and enveloped printed matter up to 5 pounds.
- Avoid waxed or oiled materials, exterior foam boxes, and unsecurely packaged articles.
- Solid corrugated fiberboard boxes as shown below.
Cushioning absorbs shock and vibration of handling. Combinations of cushioning materials are most effective. Cushion items separately.

- The parcels are irregularly shaped, such as rolls, tubes, and triangles.
Standard Mail: Unless prepared in a carrier route or 5-digit/scheme containers, Standard Mail parcels and Not Flat-Machinable pieces are subject to a $0.05 surcharge if:

For combined mailings of Standard Mail and Package Services parcels, see 705.6.0.
