What Are Class B Cigarettes Under Federal Law?

A Class B cigarette is a “large cigarette” under federal tax law: any cigarette that weighs more than three pounds per thousand units. The federal government taxes Class B cigarettes at $105.69 per thousand, roughly double the $50.33 rate for the Class A “small cigarettes” that fill nearly every pack sold in the United States. The classification exists almost entirely for excise tax purposes, and while it remains on the books, Class B cigarettes are effectively nonexistent in today’s market.

The Weight Rule That Defines Class B

Once a tobacco product qualifies as a cigarette, the Alcohol and Tobacco Tax and Trade Bureau sorts it into one of two tax classes based solely on weight. Under 27 C.F.R. § 40.24, small cigarettes are designated Class A and large cigarettes are designated Class B.1eCFR. 27 CFR 40.24 – Classification of Cigarettes The dividing line is three pounds per thousand cigarettes:

  • Class A (small): three pounds or less per thousand.
  • Class B (large): more than three pounds per thousand.

Brand, tobacco quality, flavor, and filter type have nothing to do with it. A standard king-size cigarette weighs roughly one gram, which puts a batch of a thousand at about 2.2 pounds — well under the cutoff. To fall into Class B, a cigarette would need to weigh roughly 1.4 grams or more.

Packaging has to reflect the class. TTB rules require domestic cigarette packages to display either “small” or “Tax Class A” for small cigarettes, and “large” or “Tax Class B” for large cigarettes, along with the quantity in the package.2Alcohol and Tobacco Tax and Trade Bureau.

The Federal Excise Tax Rate

The reason for the weight cutoff is money. Congress wanted heavier cigarettes taxed at a higher rate. Under 26 U.S.C. § 5701, the current federal excise tax rates are $50.33 per thousand for Class A cigarettes and $105.69 per thousand for Class B cigarettes.3Office of the Law Revision Counsel. 26 U.S.C. 5701 – Rate of Tax Those rates took effect on April 1, 2009, when the Children’s Health Insurance Program Reauthorization Act sharply raised tobacco taxes, and they remain unchanged as of 2026.4Alcohol and Tobacco Tax and Trade Bureau.

State and local excise taxes apply on top of the federal rate and vary widely by jurisdiction.

The 6½-Inch Length Rule

Federal law includes an important wrinkle for very long large cigarettes. If a Class B cigarette exceeds 6½ inches in length, it is not simply taxed once at the $105.69 rate. Instead, every 2¾ inches (or any remaining fraction) counts as a separate cigarette, and each segment is taxed at the Class A rate of $50.33.3Office of the Law Revision Counsel. 26 U.S.C. 5701 – Rate of Tax A nine-inch large cigarette, for example, would be treated as four small cigarettes for tax purposes. The rule stops a manufacturer from rolling one very long, very heavy cigarette and paying the large-cigarette rate only once.

Do Class B Cigarettes Actually Exist?

For practical purposes, no. Commercial cigarettes are standardized well under the three-pound-per-thousand line. The Class B classification dates to an era when some manufacturers made noticeably heavier cigarettes worth taxing separately. Modern production has consolidated around sizes that fall inside Class A. The category still sits in the Internal Revenue Code and TTB regulations, so any manufacturer that made a cigarette heavy enough to cross the threshold would owe the higher rate, but it is effectively a dormant classification.

Class B Cigarettes Are Not Large Cigars

The same three-pound-per-thousand cutoff appears in the rules for cigars, which causes some confusion. TTB uses that weight to divide small cigars from large cigars.5Alcohol and Tobacco Tax and Trade Bureau. Products Cigars and cigarettes are still separate product categories with different tax structures. Large cigars are taxed as a percentage of the manufacturer’s or importer’s sale price, while Class B cigarettes are taxed at a flat rate per thousand. Whether a heavy tobacco product is a cigarette or a cigar turns on wrapper material and how the product is marketed, not weight alone.

Penalties for Misclassifying Class B as Class A

Because the Class B rate is more than double the Class A rate, labeling large cigarettes as small cigarettes creates significant tax exposure. Under 26 U.S.C. § 5761, failure to pay tobacco excise tax on time adds a civil penalty of 5 percent of the unpaid tax on top of any other penalties in the code.6govinfo.gov. 26 U.S.C. 5761 – Civil Penalties

Intentional misclassification is worse. Under 26 U.S.C. § 5762, anyone who attempts to evade a tobacco tax with intent to defraud the United States, or who keeps false records or files fraudulent reports, faces a fine of up to $10,000, imprisonment of up to five years, or both, per offense. Non-fraudulent violations of the tobacco tax chapter can still bring a fine of up to $1,000, up to one year in prison, or both.7govinfo.gov. 26 U.S.C. 5762 – Criminal Penalties
