Reuse, reconditioning and remanufacture of packagings.
§ 173.28 Reuse, reconditioning and remanufacture of packagings.
(a) General. Packagings and receptacles used more than once must be in such condition, including closure devices and cushioning materials, that they conform in all respects to the prescribed requirements of this subchapter. Before reuse, each packaging must be inspected and may not be reused unless free from incompatible residue, rupture, or other damage which reduces its structural integrity. Packagings not meeting the minimum thickness requirements prescribed in paragraph (b)(4)(i) of this section may not be reused or reconditioned for reuse.
(b) Reuse of non-bulk packaging. A non-bulk packaging used more than once must conform to the following provisions and limitations:
(1) A non-bulk packaging which, upon inspection, shows evidence of a reduction in integrity may not be reused unless it is reconditioned in accordance with paragraph (c) of this section.
(2) Before reuse, packagings subject to the leakproofness test with air prescribed in § 178.604 of this subchapter shall be -
(i) Retested without failure in accordance with § 178.604 of this subchapter using an internal air pressure (gauge) of at least 48 kPa (7.0 psig) for Packing Group I and 20 kPa (3.0 psig) for Packing Group II and Packing Group III; and
(ii) Marked with the letter “L”, with the name and address or symbol of the person conducting the test, and the last two digits of the year the test was conducted. Symbols, if used, must be registered with the Associate Administrator.
(3) Packagings made of paper (other than fiberboard), plastic film, or textile are not authorized for reuse;
(4) Metal and plastic drums and jerricans used as single packagings or the outer packagings of composite packagings are authorized for reuse only when they are marked in a permanent manner (e.g., embossed) in mm with the nominal (for metal packagings) or minimum (for plastic packagings) thickness of the packaging material, as required by § 178.503(a)(9) of this subchapter, and -
(i) Except as provided in paragraph (b)(4)(ii) of this section, conform to the following minimum thickness criteria:
| Maximum capacity not over | Minimum thickness of packaging material | |
|---|---|---|
| Metal drum or jerrican | Plastic drum or jerrican | |
| 20 L | 0.63 mm (0.025 inch) | 1.1 mm (0.043 inch). |
| 30 L | 0.73 mm (0.029 inch) | 1.1 mm (0.043 inch). |
| 40 L | 0.73 mm (0.029 inch) | 1.8 mm (0.071 inch). |
| 60 L | 0.92 mm (0.036 inch) | 1.8 mm (0.071 inch). |
| 120 L | 0.92 mm (0.036 inch) | 2.2 mm (0.087 inch). |
| 220 L | 0.92 mm (0.036 inch)1 | 2.2 mm (0.087 inch). |
| 450 L | 1.77 mm (0.070 inch) | 5.0 mm (0.197 inch). |
1 Metal drums or jerricans with a minimum thickness of 0.82 mm body and 1.09 mm heads which are manufactured and marked prior to January 1, 1997 may be reused. Metal drums or jerricans manufactured and marked on or after January 1, 1997, and intended for reuse, must be constructed with a minimum thickness of 0.82 mm body and 1.11 mm heads.
(ii) For stainless steel drums and jerricans, conform to a minimum wall thickness as determined by the following equivalence formula:
Formula for Metric Units
Formula for U.S. Standard Units
where:
e1 = required equivalent wall thickness of the metal to be used (in mm or, for U.S. Standard units, use inches).
e0 = required minimum wall thickness for the reference steel (in mm or, for U.S. Standard units, use inches).
Rm1 = guaranteed minimum tensile strength of the metal to be used (in N/mm2 or for U.S. Standard units, use psi).
A1 = guaranteed minimum elongation (as a percentage) of the metal to be used on fracture under tensile stress (see paragraph (c)(1) of this section).
(5) Plastic inner receptacles of composite packagings must have a minimum thickness of 1.0 mm (0.039 inch).
(6) A previously used non-bulk packaging may be reused for the shipment of hazardous waste, not subject to the reconditioning and reuse provisions of this section, in accordance with § 173.12(c).
(7) Notwithstanding the provisions of paragraph (b)(2) of this section, a packaging otherwise authorized for reuse may be reused without being leakproofness tested with air provided the packaging -
(i) Is refilled with a material which is compatible with the previous lading:
(ii) Is refilled and offered for transportation by the original filler;
(iii) Is transported in a transport vehicle or freight container under the exclusive use of the refiller of the packaging; and
(iv) Is constructed of -
(A) Stainless steel, monel or nickel with a thickness not less than one and one-half times the minimum thickness prescribed in paragraph (b)(4) of this section;
(B) Plastic, provided the packaging is not refilled for reuse on a date more than five years from the date of manufacture marked on the packaging in accordance with § 178.503(a)(6) of this subchapter; or
(C) Another material or thickness when approved under the conditions established by the Associate Administrator for reuse without retesting.
(c) Reconditioning of non-bulk packaging.
(1) For the purpose of this subchapter, reconditioning of metal drums is:
(i) Cleaning to base material of construction, with all former contents, internal and external corrosion removed, and any external coatings and labels sufficiently removed to expose any metal deterioration that adversely affects transportation safety;
(ii) Restoring to original shape and contour, with chimes (if any) straightened and sealed, and all non-integral gaskets replaced: and
(iii) Inspecting after cleaning but before painting, Packagings that have visible pitting, significant reduction in material thickness, metal fatigue, damaged threads or closures, or other significant defects, must be rejected.
(2) For the purpose of this subchapter, reconditioning of a non-bulk packaging other than a metal drum includes:
(i) Removal of all former contents, external coatings and labels, and cleaning to the original materials of construction;
(ii) Inspection after cleaning with rejection of packagings with visible damage such as tears, creases or cracks, or damaged threads or closures, or other significant defects;
(iii) Replacement of all non-integral gaskets and closure devices with new or refurbished parts, and cushioning and cushioning materials; and components including gaskets, closure devices and cushioning and cushioning material. (For a UN 1H1 plastic drum, replacing a removable gasket or closure device with another of the same design and material that provides equivalent performance does not constitute reconditioning); and
(iv) Ensuring that the packagings are restored to a condition that conforms in all respects with the prescribed requirements of this subchapter.
(3) A person who reconditions a packaging manufactured and marked under the provisions of subpart L of part 178 of this subchapter, shall mark that packaging as required by § 178.503(c) and (d) of this subchapter. The marking is the certification of the reconditioner that the packaging conforms to the standard for which it is marked and that all functions performed by the reconditioner which are prescribed by this subchapter have been performed in compliance with this subchapter.
(4) The markings applied by the reconditioner may be different from those applied by the manufacturer at the time of original manufacture, but may not identify a greater performance capability than that for which the original design type had been tested (for example, the reconditioner may mark a drum which was originally marked as 1A1/Y1.8 as 1A1/Y1.2 or 1A1/Z2.0).
(5) Packagings which have significant defects which cannot be repaired may not be reused.
(d) Remanufacture of non-bulk packagings. For the purpose of this subchapter, remanufacture is the conversion of a non-specification, non-bulk packaging to a DOT specification or U.N. standard, the conversion of a packaging meeting one specification or standard to another specification or standard (for example, conversion of 1A1 non-removable head drums to 1A2 removable head drums) or the replacement of integral structural packaging components (such as non-removable heads on drums). A person who remanufactures a non-bulk packaging to conform to a specification or standard in part 178 of this subchapter is subject to the requirements of part 178 of this subchapter as a manufacturer.
(e) Non-reusable containers. A packaging marked as NRC according to the DOT specification or UN standard requirements of part 178 of this subchapter may be reused for the shipment of any material not required by this subchapter to be shipped in a DOT specification or UN standard packaging.
(f) A Division 6.2 packaging to be reused must be disinfected prior to reuse by any means effective for neutralizing the infectious substance the packaging previously contained. A secondary packaging or outer packaging conforming to the requirements of § 173.196 or § 173.199 need not be disinfected prior to reuse if no leakage from the primary receptacle has occurred. Drums or jerricans not meeting the minimum thickness requirements prescribed in paragraph (b)(4)(i) of this section may not be reused or reconditioned for reuse.
