1. "Explosive material(s)" include explosives, blasting agents, and detonators. See 18 U.S.C. § 841(c). "Explosives" is defined at 18 U.S.C. § 844(j). A destructive device, defined in the Commentary to §1B1.1 (Application Instructions), may contain explosive materials. Where the conduct charged in the count of which the defendant was convicted establishes that the offense involved a destructive device, apply §2K2.1 (Unlawful Receipt, Possession, or Transportation of Firearms or Ammunition; Prohibited Transactions Involving Firearms or Ammunition) if the resulting offense level is greater.
2. For purposes of this guideline:
"Controlled substance offense" has the meaning given that term in §4B1.2(b) and Application Note 1 of the Commentary to §4B1.2 (Definitions of Terms Used in Section 4B1.1).
"Crime of violence" has the meaning given that term in §4B1.2(a) and Application Note 1 of the Commentary to §4B1.2.
"Felony conviction" means a prior adult federal or state conviction for an offense punishable by death or imprisonment for a term exceeding one year, regardless of whether such offense is specifically designated as a felony and regardless of the actual sentence imposed. A conviction for an offense committed at age eighteen years or older is an adult conviction. A conviction for an offense committed prior to age eighteen years is an adult conviction if it is classified as an adult conviction under the laws of the jurisdiction in which the defendant was convicted (e.g., a federal conviction for an offense committed prior to the defendant’s eighteenth birthday is an adult conviction if the defendant was expressly proceeded against as an adult).
3. For purposes of subsection (a)(4), "prohibited person" means any person described in 18 U.S.C. § 842(i).
4. "Felony offense," as used in subsection (b)(3), means any offense (federal, state, or local) punishable by imprisonment for a term exceeding one year, whether or not a criminal charge was brought, or conviction obtained.
5. For purposes of calculating the weight of explosive materials under subsection (b)(1), include only the weight of the actual explosive material and the weight of packaging material that is necessary for the use or detonation of the explosives. Exclude the weight of any other shipping or packaging materials. For example, the paper and fuse on a stick of dynamite would be included; the box that the dynamite was shipped in would not be included.
6. For purposes of calculating the weight of explosive materials under subsection (b)(1), count only those explosive materials that were unlawfully sought to be obtained, unlawfully possessed, or unlawfully distributed, including any explosive material that a defendant attempted to obtain by making a false statement.
7. If the defendant is convicted under 18 U.S.C. § 842(h) (offense involving stolen explosive materials), and is convicted of no other offenses subject to this guideline, do not apply the
adjustment in subsection (b)(2) because the base offense level itself takes such conduct into account.
8. Under subsection (c)(1), the offense level for the underlying offense (which may be a federal,
