position. Manufactured articles, each containing not more than 100 mg (0.0035 oz) of mercury and packaged so that
the quantity of mercury per package does not exceed 1 g (0.0035 oz) are not subject to any other requirements of
this manual (see paragraph 1.10.3). Package mercury as follows:
A12.10.2.1. In inner earthenware, glass, or suitable plastic receptacles containing not more than 3.5 kg (7.7 lbs),
glass ampoules containing not more than 0.5 kg (1.1 lbs), or iron or steel quicksilver flasks containing not more than
35 kg (77 lbs) of mercury. Package in outer wooden box (4C1, 4C2, 4D, or 4F), fiberboard box (4G), plastic box
(4H2), steel drum (1A2), plywood drum (1D), fiber drum (1G), or steel jerrican (3A2).
A12.10.2.2. Use welded steel bottles with inner vaulted bottoms as single packagings. The closure must be a bolt
with a conical thread and the opening must not exceed 20 mm (0.79 inches). The maximum authorized net quantity
is 35 kg (77 pounds).
A12.10.2.3. Specification packagings are not required for manufactured articles or apparatuses containing mercury
when packaged as follows:
A12.10.2.3.1. Manufactured articles or apparatus of which metallic mercury is a component part (manometers,
pumps, thermometers, switches, etc.), except as otherwise covered in A12.10. These items must be packaged in a
strong outer packaging. The inner liner and cushioning requirements of A12.10.2 apply.
A12.10.2.3.2. Mercury switches and relays are excepted from this manual if they are of the totally enclosed leak-
proof type in sealed metal or plastic units. Thermometers, switches, and relays each containing a total quantity of
not more than 15 g (0.53 ounces) of mercury, are also excepted if installed as an integral part of a machine or
apparatus and so fitted that damage or leakage of mercury is unlikely to occur under conditions normally incident to
transport.
A12.10.2.4. Package electrons tubes, mercury vapor tubes, and similar tubes as follows:
A12.10.2.4.1. In strong outer packagings with all seams and joints sealed with self adhesive, pressure-sensitive tape
that will prevent the escape of mercury from the package. The maximum net quantity is 450 g (15.9 ounces) of
mercury per package.
A12.10.2.4.2. Package tubes with more than 450 g (15.9 ounces) of mercury in strong outer packagings having
sealed inner liners or bags of strong leak-proof and puncture-resistant material impervious to mercury, completely
surrounding the contents which will prevent the escape of mercury from the package irrespective of its position.
A12.10.2.4.3. Tubes which do not contain more than 5 g (0.2 ounces) of mercury each and that are packed in the
manufacturer’s original packaging. Maximum total net quantity is 30 g (1.1 ounces) of mercury per package.
A12.10.2.4.4. Tubes which are completely jacketed in sealed leak-proof metal cases and are packed in the
manufacturer’s original packaging.
A12.10.2. 5. Mercurial barometers complying with A12.10.2.3.1, that are loaded and unloaded from an aircraft
under the supervision of, and are accompanied in flight by a US weather official or a similar US agency official (for
example, Air Weather Service personnel), are excepted from any other requirements of this manual.
HA12.11. Nitrating Acid Mixtures; Nitrating Acid Mixtures, Spent; or Nitric Acid. Do not package nitric acid
exceeding 40 percent concentration with any other material. Package nitric acid as follows:
A12.11.1. Pack nitric acid in any concentration, which does not contain sulfuric acid or hydrochloric acid as
impurities, in:
A12.11.1.1. Stainless steel drum (1A1). Do not ship containers weighing less than 85 percent of their original
marked weight. Stainless steel used in drums must be at least 0.9 mm (.035 inches) for 55 L (15 gallon) nominal
capacity, 1.2 mm (.047 inches) for 115 L (30 gallon) nominal capacity, and 1.5 mm (.059 inches) for 210 L (55
gallon) nominal capacity. Type 304 or other grades of equivalent corrosion-resistant steel in as-welded condition
are authorized for nitric acid concentrations of up to and including 78 percent. In addition to the UN specification
markings, the marking as specified in 49 CFR 173.158(b)(1) must be included on the drum. An example of this
marking is: 304HT/1.9/2.7/TW55. For all other concentrations of nitric acid the following are authorized:
-
Type 304 heat-treated (quenched in water at 1040 degrees C [1900 degrees F]).
-
Stabilized type 347 in the as-welded condition.
-
Stabilized type 347 stress-relieved (845-900 degrees C [1550-1650 degrees F]).
-
Stabilized type 347 heat-treated (quenched in water at 1040 degrees C [1900 degrees F]).
-
Other grades of equivalent corrosion resistance.
A12.11.1.2. Expanded plastic box (4H1), with inner glass receptacles not over 2.5 L (0.66 gallons) capacity each.
Pack no more than four glass inner receptacles in one outer packaging.
