Justo Fernando Pomarc appeals his concurrent 135-month sentences for possession with the intent to distribute five or more kilograms of cocaine while onboard a vessel and conspiracy to possess with the intent to distribute five or more kilograms of cocaine while onboard a vessel, in violation of 46 App. U.S.C. § 1903(a), (g), and (j) and 21 U.S.C. § 960(b)(1)(B)(ii). After review, we affirm Pomarc’s sentences.
I. BACKGROUND
The United States Coast Guard (“USCG”) spotted a “go fast” boat in international waters off the coast of Colombia. The go fast boat engaged in evasive maneuvers while its crew threw bales of cocaine overboard. The USCG shot and disabled the go fast boat’s engines. Upon boarding the go fast boat, the USCG found four crew members, including Pomarc, and a captain. The USCG recovered eight bales of cocaine from the water. Crew member Pedro Vallenquella stated that the go fast boat had been carrying sixty bales of cocaine. Based on the weight of the recovered cocaine bales and statements given by the crew, it was determined that the go fast boat was transporting approximately 1,500 kilograms of cocaine. After being arrested, Pomarc stated that he had been paid $17,000 prior to taking the trip and was promised an additional $17,000 upon its completion. He also confirmed the captain had ordered the crew to jettison the cocaine.
The presentence investigation report (“PSI”) set Pomarc’s base offense level at 38, pursuant to U.S.S.G. § 2Dl.l(c)(l), based on the cocaine on the go-fast boat being 150 kilograms or more.1 After a two level safety-valve reduction and a three-level reduction for acceptance of responsibility, Pomarc’s total offense level was 33. With a criminal history category of I, the PSI recommended an advisory guidelines range of 135 to 168 months.
At sentencing, Pomarc argued that he was entitled to a minor-role reduction. The district court overruled Pomarc’s objection and adopted the guidelines calculations in the PSI.
Pomarc asked for a sentence at the low end of the guidelines range. In mitigation, Pomarc stated that he had a family he needed to assist.
The district court sentenced Pomarc to concurrent 135-month sentences. In arriving at this sentence, the district court stated that it considered the advisory guidelines range and the 18 U.S.C. § 3553(a) factors. Pomarc filed this appeal.
II. DISCUSSION
On appeal, Pomarc argues that the district court erred by failing to grant him a minor-role reduction, pursuant to U.S.S.G. § 3B1.2. We review for clear error a district court’s determination of a defendant’s qualification for a role reduction. United States v. De Varon, 175 F.3d 930, 937 (11th Cir.1999) (en banc). The defendant has the burden of establishing his role in the offense by a preponderance *952of the evidence. Id. at 939. Two principles guide a district court’s consideration: (1) the court must compare the defendant’s role in the offense with the relevant conduct attributed to him in calculating his base offense level; and (2) the court may compare the defendant’s conduct to that of other participants involved in the offense. Id. at 940-45. When the relevant conduct attributed to a defendant is identical to his actual conduct, he cannot prove that he is entitled to a minor-role adjustment simply by pointing to some broader scheme for which he was not held accountable. Id. at 941.
The district court did not clearly err in refusing Pomarc a minor-role reduction. Under the first prong of De Varon, the district court held Pomarc accountable for only his own conduct, namely his involvement in the transporting of the 1,500 kilograms of cocaine, a substantial quantity of drugs. Under the second prong of De Varón, Pomarc was at least as culpable as his crewmates.
Contrary to Pomarc’s contention, the district court did not operate under a mistaken belief that drug couriers were per se ineligible for a minor-role reduction. The district court considered whether a minor-role reduction was appropriate in Pomarc’s case and determined that it was not.
Pomarc also argues that the district court erred in imposing an unreasonable sentence, in light of the 18 U.S.C. § 3553(a) factors. Pomarc contends that his sentence is too severe given his lack of a criminal history and because he did not commit his crimes within the United States, but from Colombia, where large amounts of cocaine are readily available and half the population lives in poverty.
After United States v. Booker, a district court in determining a reasonable sentence, must consider the correctly calculated sentencing range under the Sentencing Guidelines and the factors in § 3553(a). See U.S. v. Booker, 543 U.S. 220, 258-64, 125 S.Ct. 738, 764-67, 160 L.Ed.2d 621 (2005); United States v. Talley, 431 F.3d 784, 786 (11th Cir.2005). We review the ultimate sentence imposed for unreasonableness in light of § 3553(a)’s factors and the reasons given by the district court. United States v. Williams, 435 F.3d 1350, 1354-55 (11th Cir.2006). The party who challenges the sentence bears the burden of showing that it is unreasonable. Talley, 431 F.3d at 788. Although there is no presumption of reasonableness for a sentence within the advisory guidelines range, when the district court imposes a guidelines sentence, “we ordinarily will expect that choice to be a reasonable one.” Id.
After review, Pomarc fails to show that his sentences are unreasonable. Pomarc’s concurrent 135-month sentences were at the bottom of the advisory guidelines range and only one year above the ten-year mandatory minimum for his crimes. See 21 U.S.C. § 960(b)(1)(B)(ii). Apart from the district court’s refusal to give a minor-role reduction, Pomarc does not dispute the district court’s guidelines calculations. The district court considered Pomarc’s arguments in mitigation regarding his family circumstances. The district court also indicated that it had considered the § 3553(a) sentencing factors and believed that a sentence at the low-end of the advisory guidelines range was sufficient but not greater than necessary to comply with the statutory purposes of sentencing.
Pomarc’s argument that the guidelines were not designed to address the importation of drugs from other countries is without merit. Part D of the Sentencing Guidelines explicitly covers offenses involving the importation of drugs.
AFFIRMED.
