intra-BMC or inter-BMC and whether it is machinable
or nonmachinable, which is discussed below.
Serving Bulk Mail Centers (BMCs)
Once you have determined the weight and zone of
destination, you must also determine if the article is
within the delivery area of your serving bulk mail
center (which is intra-BMC) or outside your bulk mail
center (which is inter-BMC). The ZIP Code in the
address of the article presented for mailing is used to
determine the postal zone, and whether or not the
article is intra-BMC or inter-BMC. Using the first
three digits of the ZIP Code, refer to the bottom of your
USPS official zone chart (figure 4-3). If the first three
digits of the ZIP Code match those listed, the article is
within the delivery area of your serving BMC.
Nonmachinable (Outside Mail)
If an article presented for mailing is determined to
be outside the delivery area of your serving BMC, you
must then determine if the article can be handled by
machine (machinable) or must be physically handled
by sorting personnel (nonmachinable). If an article is
defined by one or more of the following charac-
teristics, it is nonmachinable and is processed as
outside mail (not sackable).
It is more than 34 inches long, 17 inches wide, or
17 inches high, or weighing more than 35
It contains more than 24 ounces of fluid in glass
containers, or 1 gallon or more of liquid in metal
or plastic containers.
It is not wrapped properly or is metal-banded.
It is a can, roll, or tube, or wooden or metal box.
It is a shrub or tree.
It contains perishables, such as eggs.
It contains books, printed matter, or business
forms weighing more than 25 pounds.
It is a high-density parcel weighing more than 15
pounds, exerting more than 60 pounds per square
foot pressure on its smallest side.
Within (Intra-BMC) BMC Discount
If the article is addressed for delivery within the
delivery area of your serving BMC, then you would
charge the Standard Mail (B) rate with a discount using
the current rate chart listed in Module R of the DMM.
Machinable/Nonmachinable Inter-BMC Mail
If an article is addressed for delivery outside the
delivery area of your serving BMC (inter-BMC) and
the article is determined to be machinable, then the
no-discount, no-surcharge rate applies. On the other
hand, if an article is addressed for delivery outside the
delivery area of your serving BMC and the article is
determined to be nonmachinable, the applicable rate
plus the surcharge applies.
However, if a special
handling fee is paid, the nonmachinable surcharge is
not to be charged.
The nonmachinable surcharge must be assessed on
inter-BMC parcel post without special handling if any
of the following apply:
The length exceeds 34 inches.
The height exceeds 17 inches.
The width exceeds 17 inches.
The weight exceeds 35 pounds.
The packaging or contents are among those
listed in Module E of the DMM.
The oversize surcharge must be assessed on a
parcel post article if the combined length and girth falls
between 108 and 130 inches.
Parcel post is the only mail class that accepts
articles with a combined length and girth over 108
inches. The oversized rate for the appropriate zone
must be charged for these articles. The oversized rate
is higher than the 70-pound rate, however the weight
limit remains 70 pounds.
