The Alcohol and Tobacco Tax and Trade Bureau (TTB) has released updated metric conversion tables and guidance to help importers, bottlers, distributors, and compliance teams accurately convert wine and distilled spirits container sizes into U.S. gallons for tax and reporting purposes. The updated resources reflect the expanded authorized “standards of fill” now permitted for beverage alcohol products sold in the United States.
The update follows TTB’s recent expansion of allowable container sizes for wine and distilled spirits, which added numerous new metric sizes to the U.S. market beginning in 2025. The revisions impact both domestically bottled and imported products and are especially relevant for importers managing excise tax calculations, customs documentation, labeling compliance, and inventory reporting.
Why This Matters for Beverage Alcohol Importers
TTB’s updated conversion tables are designed to help industry members correctly calculate taxable quantities based on authorized container sizes. As more nontraditional bottle and can formats enter the market, accurate gallon conversions become increasingly important for:
- Excise tax calculations
- Customs and import documentation
- Inventory reconciliation
- Label approvals and compliance reviews
- Distributor and wholesaler reporting
The updated tables now reflect recently approved standards of fill for both wine and distilled spirits, including newer container sizes such as 700 mL, 720 mL, 568 mL, 331 mL, 945 mL, and additional liter formats.
Expanded Standards of Fill
TTB significantly expanded approved standards of fill in a final rule that became effective January 10, 2025. The rule added 13 new authorized sizes for wine and 15 new sizes for distilled spirits. It also removed the distinction between cans and other container types for spirits packaging.
Examples of newly authorized wine container sizes include:
- 180 mL
- 300 mL
- 330 mL
- 568 mL (19.2 oz.)
- 700 mL
- 720 mL
- 1.8 L
- 2.25 L
Newly authorized distilled spirits sizes include:
- 250 mL
- 331 mL
- 355 mL
- 475 mL
- 570 mL
- 700 mL
- 710 mL
- 945 mL
- 2 L
- 3 L
- 3.75 L
These expanded sizing options provide additional flexibility for producers and importers while creating new compliance considerations for taxable volume calculations and labeling accuracy.
Importers Should Review Labeling and Reporting Processes
Importers of wine and distilled spirits should confirm that internal systems, customs documentation processes, and product databases reflect the updated authorized sizes and corresponding gallon conversions. Companies using older conversion charts or legacy ERP data may need updates to avoid discrepancies in tax reporting or TTB filings.
Teams responsible for beverage alcohol imports should also review net contents labeling requirements to ensure product labels align with current TTB standards for authorized container sizes and formatting requirements.

For importers managing beverage alcohol compliance, these updates are another reminder that packaging changes can create downstream impacts across customs entry filing, excise tax reporting, labeling, and supply chain systems.
