You reference § 173.158(e), which states that when nitric acid of' less than 90 percent concentration is packed in wooden or fiberboard outer packagings, the glass inner packagings must be packed in tightly-closed, intermediate packagings and cushioned with an absorbent material. Specifically, you ask if the intent of this section is to require enough absorbent material to absorb the entire contents of the package. The answer is yes. The requirement for absorbent material is such that there must be a sufficient amount to absorb the entire liquid contents of the package. This is consistent with similar requirements in other sections of the HMR. I hope this information is helpful. Please contact us if we can be of further assistance. Sincerely, Chief, Standards Development Branch Standards and Rulemaking Division <<>> Please submit this as a letter in interpretation. Please let me know if you have any questions.

When placed in wooden or fiberboard outer packagings, the glass inner packagings must be packed in tightly-closed, intermediate packagings, cushioned with an absorbent material. The intermediate packaging and absorbent material must be compatible with the nitric acid. See §173.24(e). My question relates to the highlighted section, and very simply, is the intent of the use of absorbent material to mean that enough absorbent is required to absorb the entire liquid content of the glass bottles within the package? Thank you for clarification of this matter.
