Chapter Overview
Chapter 21 of the HTS is a catch-all for miscellaneous edible preparations — products that do not fit neatly into earlier food chapters. It covers sauces, soups, ice cream, yeast, protein concentrates, and, most notably for modern importers, dietary supplements, vitamins, and nutraceutical preparations. Heading 2106 ("food preparations not elsewhere specified or included") is one of the most heavily used headings in all of U.S. customs trade.
The dietary supplement and nutraceutical market in the United States exceeds $50 billion annually, with a significant share of products manufactured abroad or using imported ingredients. Chapter 21 is where most supplement capsules, gummies, powders, and tablets classify — unless their composition or labeling claims push them into Chapter 30 (pharmaceutical products) or another chapter entirely.
The classification challenge in Chapter 21 is that the line between a "food preparation" and a "medicament" is driven by the product's composition, format, dosage, and — critically — its label claims. A product sold as a dietary supplement with structure/function claims stays in Chapter 21. The same product with therapeutic or disease claims on its label may reclassify to Chapter 30. This makes Chapter 21 one of the most classification-sensitive chapters in the HTS. For more on food import compliance, see our food and beverage industry page.
Common HTS Codes in Chapter 21
| HTS Code | Description | Representative Duty Rate |
|---|---|---|
| 2101.11 | Extracts, essences, and concentrates of coffee | Free – 8.5% |
| 2103.10 | Soy sauce | 3% |
| 2103.90 | Other sauces and preparations; mixed condiments | Free – 6.4% |
| 2104.10 | Soups and broths and preparations thereof | 3.2% |
| 2106.10 | Protein concentrates and textured protein substances | 6.4% |
| 2106.90.54 | Food preparations NESOI, blended syrups | 6.4% |
| 2106.90.98 | Other food preparations NESOI (common supplement classification) | 6.4% |
| 2106.90.42 | Food preparations containing milk solids | 6.4% |
| 3004.90 | Medicaments (when therapeutic claims move product out of Ch. 21) | Free |
Note: The 2106.90 subheading is one of the broadest in the entire tariff schedule. Supplements, protein powders, energy bars, pre-workout formulas, and countless other preparations all classify here. The specific 10-digit code depends on ingredient composition (dairy content, sugar content, alcohol content) and product characteristics. Do not assume all supplements share the same subheading.
Duty Rates & Additional Tariffs
Most Chapter 21 food preparations carry MFN duty rates in the range of 3% to 6.4%. Dietary supplements under heading 2106 typically face a 6.4% MFN rate. While this is moderate compared to chapters like apparel or footwear, it represents a meaningful cost for high-volume supplement importers.
Section 301 exposure: Supplements and food preparations sourced from China face Section 301 tariffs that can add 7.5% to 25% on top of the MFN rate. Given that China is a major global supplier of supplement ingredients and finished supplement products, Section 301 exposure is a significant landed-cost factor for many importers in this category.
Chapter 30 reclassification risk: Products that are reclassified from Chapter 21 (food preparations) to Chapter 30 (pharmaceutical products) may face a different duty rate — often duty-free under heading 3004. While a lower rate sounds advantageous, Chapter 30 classification triggers Drug Establishment Registration requirements with FDA and significantly higher compliance obligations. The reclassification itself often results from an FDA determination, not an importer's choice.
PGA & Compliance Requirements
FDA Prior Notice
All food preparations and dietary supplements require FDA prior notice. The filing must be received by FDA before the shipment arrives at the U.S. port. For supplement imports, the prior notice submission must accurately describe the product, its ingredients, and its intended use.
FDA Label Review
Dietary supplements are subject to specific FDA labeling requirements that differ from conventional food labels. Required elements include a Supplement Facts panel (not a Nutrition Facts panel), a complete ingredient list, the manufacturer or distributor name and address, and compliant structure/function claims with the required disclaimer. Products with non-compliant labels are subject to detention and refusal of admission. FDA routinely inspects supplement labels at the port.
FSVP (Foreign Supplier Verification Program)
Supplement importers must maintain FSVP documentation for each foreign supplier. This includes hazard analysis, supplier verification activities, and corrective action records. Given that supplement ingredients often come from multiple countries and are blended or encapsulated in a final manufacturing location, FSVP documentation can be complex. See our FSVP compliance guide for details.
New Dietary Ingredient (NDI) Notifications
Supplements containing ingredients that were not marketed in the U.S. before October 15, 1994, may require a New Dietary Ingredient (NDI) notification to FDA. The NDI process requires the manufacturer or importer to provide evidence of safety. Importing a supplement containing an NDI without the required notification can result in FDA enforcement action.
Country of Origin Considerations
The global supplement supply chain is complex. Ingredients may be sourced from multiple countries, blended or manufactured in another, and packaged in yet another. Country of origin for customs purposes is the country where the last substantial transformation occurred.
USMCA preference: Supplements manufactured in Mexico or Canada may qualify for duty-free treatment under USMCA, provided the rules of origin are met. For blended products, the substantial transformation analysis can be complex and may require detailed documentation of the manufacturing process.
Section 301 on China-origin products: China is a major source of both finished supplements and supplement ingredients (vitamins, amino acids, botanical extracts). Products manufactured in China or substantially transformed there face Section 301 tariffs. Some importers have restructured their supply chains to perform final manufacturing in countries not subject to Section 301 tariffs, but the substantial transformation must be genuine — simple repackaging in a third country does not change the country of origin.
Ingredient vs. finished product origin: For customs purposes, origin is based on the finished product, not individual ingredients. A supplement manufactured in India using Chinese-sourced vitamins has India as its country of origin. However, importers should be aware that FDA's FSVP requirements apply to the entire supply chain, not just the country of final manufacture.
Common Classification Mistakes
Label Claims That Shift the Chapter
The most consequential classification mistake in Chapter 21 is using label language that moves the product out of the chapter entirely. Structure/function claims like "supports immune health" keep a product in Chapter 21. Disease claims like "treats arthritis" or "prevents heart disease" push the product toward Chapter 30 classification as a medicament — and trigger drug-level FDA regulation. Importers must review their labels for claim language before filing the customs entry.
Assuming All Supplements Use the Same HTS Code
The 2106.90 subheading branches into multiple 8-digit and 10-digit codes based on ingredient composition. Products containing dairy derivatives, specific sugar content, or alcohol classify under different subheadings. Importers who use a single code for their entire supplement line without checking the ingredient-specific splits are likely misclassifying some products.
Overlooking Ingredient Declarations
The ingredient list on the label must match the commercial invoice and the actual product composition. Discrepancies between these three — the label, the invoice, and the product — are a common trigger for FDA examination and CBP reclassification. Importers should verify consistency across all documents before the product ships.
