General Rules of Packaging, Marking and Quality
Certification for Precision Alloys
1 Scope
This Standard specifies the general requirements for the packaging, marking, storage
and quality certification for precision alloys.
This Standard is applicable to the packaging, marking, storage and quality certification
of finished products of precision alloy hot-forged (rolled) bars and flat bars, hot-rolled
wire rods and strips, cold (warm) rolled strips, cold-rolled plates, cold-drawn wires and
(polished) bars, and cold-rolled (drawn) pipes.
2 Normative References
This Standard does not have normative references.
3 Terms and Definitions
The following terms and definitions are applicable to this document.
3.1 Package
Package refers to the operation activity of applying certain technical methods in the
process of using materials and auxiliary materials to protect products, facilitate storage
and transportation, and promote sales during the circulation process.

3.2 Label
Label refers to an article made of paper or other materials that is fixed on the package
or product to indicate product name, alloy designation, furnace (batch) number,
specifications and supply-side’s name (trademark).

3.3 Tap
Tap refers to a movable label that is fixed on the package or product with iron wire, U-
shaped nail, flat-head nail and nylon cable ties, etc.
equidistance with galvanized iron wires, or stainless steel wires, or straps with a
diameter not less than 4 mm. The wire rods packed in bundles shall be radially re-
bundled for no less than 2 passes.
4.3 Strips
4.3.1 Hot-rolled strips
4.3.1.1 Hot-rolled strips shall be packed in coils or in straight strips in bundles. The coil
weight of the strips shall be not greater than 600 kg. The bundle weight of the strips
packed in bundles shall be not greater than 80 kg for manual loading and unloading,
and not greater than 1,000 kg for mechanical loading and unloading.
4.3.1.2 Each coil (bundle) of strips shall be bundled up for at least 3 passes in radial
equidistance with galvanized iron wires, or stainless steel wires, or straps with a
diameter not less than 4 mm.
4.3.2 Cold (warm) rolled strips
4.3.2.1 Cold-rolled strips shall be packed in coils; cold (warm) rolled straight strips shall
be packed in bundles.
4.3.2.2 The weight of each coil (bundle) of strips shall be not greater than 80 kg for
manual loading and unloading, and not greater than 5,000 kg for mechanical loading
and unloading.
4.3.2.3 Before packaging, the strips shall receive anti-corrosion or oiling treatment
(except for vacuum packaging). The layers of soft and deep-drawn strips shall be lined
with volatile rust preventive paper or other neutral anticorrosive papers: for soft and
deep-drawn strips delivered in coils, if the coils are tightly wound and there is no sliding
between the layers, then, the anticorrosive paper is not required.
4.3.2.4 Straight strips shall carry out the form of bundled package for encasement. The
layers of the strips shall be lined with volatile rust preventive paper or other neutral
anticorrosive papers. After each bundle is packed with volatile rust preventive paper or
other moisture-proof papers and packing sheet, and before being encased, it shall be
bundled up for at least 2 passes in equidistance with galvanized iron wires or straps.
4.3.2.5 The packaging and bundling methods of cold-rolled strips in coils shall comply
with the stipulations of Table 2. The packaging of strips in wooden boxes is shown in
Figure 1, Figure 2, Figure 3, or Figure 4 and Figure 5.
4.3.3.1 Plates shall be encased in the form of bundles. The weight of each box shall
be not greater than 1,000 kg.
4.3.3.2 Before packaging, the plates shall receive anti-corrosion and oiling treatment.
If there are special requirements, they shall be indicated in the contract.
4.3.3.3 The layers of the plates shall be lined with volatile rust preventive paper or other
neutral anticorrosive papers. After each bundle is packed with volatile rust preventive
paper or other moisture-proof papers and packing sheet, and before being encased, it
shall be bundled up for at least 2 passes in equidistance with galvanized iron wires or
straps.
4.3.3.4 The packaging of plates in wooden boxes is shown in Figure 1.
4.4 Cold-drawn Wires and (polished) Bars
4.4.1 Cold-drawn wires
4.4.1.1 Cold-drawn wires shall receive anti-corrosion treatment, then, be packed in
reels (or bundles). The weight of each reel (or bundle) of wires shall be specified by
the supply-side in accordance with the product standard. If it is not specified in the
product standard, the weight of each reel (or bundle) of wires shall be not greater than
150 kg.
4.4.1.2 Each reel of cold-drawn wire shall be composed of one wire. The shaft-winding
wire shall be neatly arranged and the winding shall be tight. For cold-drawn wires with
a nominal diameter not greater than 4 mm, the ends shall be bent into the reel or be
marked. For cold-drawn wires with a nominal diameter greater than 4 mm, the ends
shall be clearly marked. One or several reels of wires can be packed as a bundle.
4.4.1.3 Cold-drawn straight wires shall be firmly bundled with galvanized steel wires.
Each bundle shall be bundled up for at least 3 passes in equidistance.
4.4.1.4 The packaging form, packaging and bundling methods, and wooden box
packaging method of the wires shall comply with the stipulations of Table 3.
4.4.2 Cold-drawn (polished) bars
4.4.2.1 Cold-drawn and cold-drawn polished bars shall receive anti-corrosion

packaging method of the cold-drawn and cold-drawn polished bars shall comply with
the stipulations of Table 3.
4.6 Special Requirements
In accordance with the demand-side’s requirements, through the negotiation between
the demand-side and the supply-side, and statement in the contract, other packaging
forms or packaging materials may be used.

pasting, etc. The marking shall be clear and firm; all externally hanged and pasted tags
(labels) shall be prevented from being contaminated and falling off during
transportation and handling.
5.2 Coiled strips shall be marked coil by coil with alloy designation, furnace number,
specifications, weight and state on the end of the coil outer ring. On the outer
packaging of each coil, at least one label shall be attached and marked with: supply-
side’s name (trademark), alloy designation, furnace number, specifications, state, net
weight and production date, etc.
5.3 Bars with a nominal diameter not less than 50 mm shall be marked bar by bar with
alloy designation, furnace number and specifications at the end or on the surface.
5.4 For products delivered in reels (bundles), at least 2 tags shall be hanged or at least
1 label shall be pasted on each reel (bundle), indicating supply-side’s name
(trademark), alloy designation, furnace (batch) number, specifications, weight and
delivery state, etc. The tag (label) shall be firmly tied up or pasted on the reel (bundle)
on the side that is convenient for inspection.
5.5 For precision alloy products packed and delivered in wooden (iron) boxes, the outer
surface of the box shall be printed or pasted with a label, indicating supply-side’s name
(trademark), alloy designation, furnace (batch) number, specifications, gross weight,

6 Storage
6.1 Precision alloy products shall be stored in a clean, dry, rain-proof and moisture-
proof place. If necessary, the bottom layer may use dry timber to prevent moisture.
6.2 After the package is opened, moisture-proof protection shall be implemented in
time.
