Section 301 investigations: where they stand
Written comments in USTR's two new Section 301 investigations (structural excess capacity in 16 economies and forced labor in 60 economies) were due April 15, 2026. Forced-labor hearings were held April 28 and 29; excess-capacity hearings were scheduled to begin May 5 and continue as necessary until May 8. On June 2, 2026, USTR made findings in the forced-labor cases and proposed additional Section 301 duties of 10 percent (economies with forced-labor import prohibitions or reciprocal trade commitments) and 12.5 percent (all others) across the 60 economies, which include China, India, and Vietnam. Written comments were due July 6, 2026, and public hearings on the proposed actions were held July 7 through July 9, 2026, at the U.S. International Trade Commission. On July 23, 2026 USTR took final action imposing the tiered duties across the 60 economies; the additional duties apply to entries on or after 12:01 a.m. eastern time July 24, 2026 (goods loaded and in transit before that instant and entered before July 28, 2026 are excepted), and Annexes I and II of the Notice list product exemptions. Lines that U.S. note 52 exempts (vitamins under 2936, many mineral salts, raw tea and spice forms) are exempt from this layer as entered, but can still carry older China Section 301 duties. The excess-capacity investigation, whose initiation fact sheet lists “processed food and beverages” among 20 illustrative sectors, has no proposed action yet. Confirm your specific HTS classification and any Annex exemption with a licensed customs broker. Snapshot sources checked on October 5, 2026.
Supplement imports met three tariff programs in 2026: older Section 301 duties on Chinese goods at 7.5 or 25 percent depending on the HTS line, a temporary 10 percent Section 122 import surcharge on entries February 24 through July 23, 2026 (it terminated by operation of law at 12:01 a.m. EDT July 24, 2026), and the forced-labor Section 301 duties on entries from July 24, 2026 (12.5 percent for China, 10 percent for India). Sources: the U.S. tariff schedule, the Section 122 proclamation and the Federal Register. Each program has its own exemptions. Glycine imported from China at HTS 2922.49.43 has 4.2 percent MFN duty plus 25 percent older Section 301 duty and 12.5 percent forced-labor duty for supplement use. That is 41.7 percent across the modeled layers, before any other duties or fees. Vitamin A at 2936.21.00 has none of those duties. The U.S. supplement industry imports 80 percent of its raw ingredients from China, according to May 2025 reporting by NutraIngredients.
This page is a dated snapshot. Its recorded official government sources were checked on October 5, 2026. If you are reviewing ingredient sourcing risk, confirm the exact HTS classification, country of origin, and any applicable exclusions with a licensed customs broker. Multiple trade programs can apply to the same shipment.
The short answer
Dietary supplement manufacturers must comply with 21 CFR Part 111 (Current Good Manufacturing Practice for dietary supplements). This includes requirements for personnel, facilities, equipment, production, laboratory operations, and record-keeping.
Official Tariff Programs to Check
These are the trade actions verifiable from official government sources checked on October 5, 2026.
| Program | Official Status | Why It Matters |
|---|---|---|
| Section 301 China tariffs | Active for covered tariff lines. Coverage turns on the 8-digit HTS subheading in the USITC China Tariffs list and on any product exclusion in U.S. note 20; active exclusions run through November 9, 2026. | These duties are not uniform across all supplement inputs. Some products face additional duty and others do not, depending on how they are classified. |
| China reciprocal tariff rate | According to the White House executive order issued in May 2025, the heightened China-specific rate was suspended and a 10 percent ad valorem rate was kept in force during the suspension period. A later White House fact sheet described that 10 percent rate as remaining in place through November 10, 2026. However, the Supreme Court’s IEEPA ruling (February 20, 2026) invalidated the legal authority under which this reciprocal rate was imposed. Chinese goods faced the general Section 122 surcharge of 10 percent on entries made February 24 through July 23, 2026 (it terminated by operation of law July 24, 2026) plus older Section 301 duties of 7.5 or 25 percent by product. Since July 24, 2026, covered Chinese goods carry the 12.5 percent forced-labor Section 301 duty instead of the surcharge. | The November 10, 2026 date is from the pre-ruling IEEPA framework. For cost planning, the operative date is July 24, 2026 (Section 122 expiration and the start of the forced-labor duties). Do not plan around the November date. |
| IEEPA tariffs (ended) | Struck down by the Supreme Court on February 20, 2026 (Learning Resources, Inc. v. Trump). Executive Order 14389 of February 20, 2026 ordered that the IEEPA duties no longer be in effect or collected. CBP processes refund requests for IEEPA duties from importers of record and their customs brokers through CAPE declarations in ACE. | Country-specific IEEPA rates from 2025 are no longer in effect. Per Learning Resources v. Trump, the reciprocal rate on Chinese goods reached 125 percent, which brought the total effective rate on most Chinese goods to 145 percent. Do not use 2025 IEEPA rates for current cost planning. |
| Section 122 surcharge | The February 2026 White House proclamation (Proclamation 11012, 91 FR 9339) imposed a temporary 10 percent surcharge for entries February 24 through July 23, 2026. Its entry window ended at 12:01 a.m. EDT July 24, 2026. On May 7, 2026, the U.S. Court of International Trade ruled the surcharge unlawful (Slip Op. 26-47, State of Oregon v. United States), with an injunction limited to the named importer plaintiffs. On June 11, 2026, the Federal Circuit granted a stay of that injunction pending appeal, allowing collection during the remaining entry window. That historical stay did not extend the proclamation’s July 24 termination date. | The surcharge was additive to existing Section 301 duties within its entry window. Vitamins under 2936, CoQ10 at 2914.62.00 and many 2922 amino-acid lines were exempt under U.S. note 2(aa)(ii); glycine at 2922.49.43 was not. Entries on or after July 24, 2026 carry no Section 122 surcharge under this proclamation. The separate forced-labor Section 301 action must be checked for those entries. |
| Section 301 forced-labor duties | Final action July 23, 2026, published at 91 FR 47318. Additional duties of 12.5 percent for China and 10 percent for India apply to entries on or after 12:01 a.m. eastern time July 24, 2026, on top of any older Section 301 duty. U.S. note 52 lists the exempt lines. | Vitamin lines under 2936 are exempt as entered. Listed amino acids and CoQ10 are exempt only for pharmaceutical use, so supplement-use entries pay the duty. Botanical extracts under 1302.19 from China or India are covered. |
How Tariffs Affect Different Ingredient Categories
The guide above warns against using a generic 45 percent or more assumption. Here is what to use instead. Not every supplement ingredient faces the same tariff exposure. Check MFN duty, older China Section 301 duties, and the newer forced-labor layer separately. For example, magnesium sulfate at 2833.21.00 is exempt from the new layer but retains its older 25 percent China duty plus 3.7 percent MFN. The expired Section 122 surcharge and the historical reciprocal-tariff exemptions have separate rules. Current rates depend on the ingredient's origin, use, entry date and HTS classification.
Historical table: these statuses describe the 2025 reciprocal-tariff Annex II, a program invalidated in February 2026. They do not establish an exemption from older China Section 301 duties or the newer forced-labor layer. For example, raw tea can be exempt from the new layer while retaining an older 7.5% China duty. Check the current rate matrix and each program's rules for your HTS line, origin and use.

Verify your specific HTS code with a licensed customs broker before making sourcing commitments. Data verified 2026-10-05.
This split matters for product development. A Chinese-origin multivitamin input built on vitamin lines under 2936 carries no China Section 301 duty, while turmeric and ashwagandha extracts under 1302.19 carry both Section 301 layers. Knowing which category your key ingredients fall into is the first step toward an accurate landed-cost model.
New Section 301 Investigations (March 2026)
USTR initiated two new sets of Section 301 investigations on March 11 and March 12, 2026. Neither initiation notice names dietary supplements. The forced-labor action now reaches products of the investigated economies, and the excess-capacity sector list includes processed food and beverages.
Excess Capacity Investigation
USTR is investigating structural excess capacity in manufacturing sectors across 16 economies including China, India, the EU, Vietnam, and Japan. Its initiation fact sheet gives an illustrative list of 20 sectors, and “processed food and beverages” is among them. The notice scheduled public hearings at the U.S. International Trade Commission to begin May 5, 2026 and continue as necessary until May 8. The investigation has no proposed action yet.
Forced Labor Investigation
According to USTR's forced-labor fact sheet, the 60 investigations initiated March 12, 2026 focus on 60 top U.S. trading partners, “collectively covering more than 99% of U.S. imports in 2024,” and concern the enforcement of forced-labor import prohibitions. China, India, and Vietnam are among them. The International Labour Organization estimates that, as of 2021, 28 million people globally are in forced labor, an increase of 2.7 million since 2016. Public hearings were held April 28 and 29, 2026. On June 2, 2026, USTR made findings and proposed additional Section 301 duties of 10 to 12.5 percent across these economies; written comments were due July 6, 2026, and public hearings on the proposed actions were held July 7 through July 9, 2026, at the U.S. International Trade Commission.
What this means for supplement brands
As of October 5, 2026, the forced-labor investigation has reached final action: on June 2, 2026 USTR proposed additional Section 301 duties of 10 percent (economies with forced-labor import prohibitions or reciprocal trade commitments) to 12.5 percent (all others), the comment window closed July 6, public hearings were held July 7 through 9, 2026, and on July 23, 2026 USTR took final action imposing the tiered duties. The additional duties apply to entries on or after 12:01 a.m. eastern time July 24, 2026 (goods loaded and in transit before that instant and entered before July 28, 2026 are excepted), and Annexes I and II of the Notice list product exemptions. The excess-capacity investigation has no proposed action yet. These duties are additive to existing Section 301 duties; the Section 122 surcharge terminated by operation of law before they took effect, so the two never stack. Brands sourcing heavily from China or India should monitor the exemption mapping and confirm their HTS codes with a customs broker.
In March 2026, the law firm Troutman Pepper described the investigations as running on “relatively compressed timelines” and expected USTR “to move quickly once the records are developed.” Final action in the forced-labor investigations came on July 23, 2026, the day before the Section 122 surcharge terminated by operation of law. In practice a brand sees the surcharge drop away and, on covered lines, the new Section 301 duties arrive at the same July 24, 2026 entry instant. Troutman Pepper reads the investigations, because Section 122 is time-limited, as “an effort to build a more durable, litigation-resistant legal foundation for long-term trade measures.”

Botanical Exemption Details
Not all botanicals face the same tariff exposure. A November 2025 order moved 57 commodity codes that AHPA members import against into Annex II, fully exempting them from the reciprocal tariffs then in force; AHPA credits its own advocacy. Read that as history: the reciprocal-tariff program rested on IEEPA, which the Supreme Court held does not authorize tariffs (decided February 20, 2026). What survives is the distinction the exemptions drew, between raw botanical forms and concentrated extracts, because the July 2026 forced-labor action draws the same line.
That raw-versus-extract split is the part still worth planning around. Raw turmeric (0910.30) and tea leaf sit in the forced-labor action's exempt-as-entered list; concentrated curcuminoid and polyphenol extracts (1302.19) do not. If your formulation uses extracts, do not assume it shares the raw form's status. Verify your specific HTS code. See the ingredient table above for form-dependent status.
The gaps AHPA reported in December 2025 show how narrow the old exemptions were: ashwagandha was “not found anywhere in the executive orders.” A separate November 2025 annex offered relief only through a bilateral trade agreement, and its entry for “other” vegetable extracts covered only four specific extracts.

How Tariff Costs Have Changed Since 2025
The tariff landscape for supplement ingredients has shifted dramatically since 2025. In April 2025, at the start of the IEEPA tariff era, UNPA President Loren Israelsen put the effective tariff rate for a large number of dietary ingredients at between 55 percent and nearly 70 percent (SupplySide, April 3, 2025). The reciprocal rate on Chinese goods then reached 125 percent, which brought the total effective tariff rate on most Chinese goods to 145 percent (Learning Resources, Inc. v. Trump).
The Supreme Court struck down IEEPA tariffs on February 20, 2026 (Learning Resources, Inc. v. Trump). Those rates are no longer in effect. The current regime is lower but still significant.
| Program | Rate | Status |
|---|---|---|
| IEEPA reciprocal tariffs | 10 to 125 percent by country | Struck down (Feb 2026) |
| Section 301 (China) | 7.5-25% by HTS code | Active |
| Section 122 surcharge | 10% on products of any country, with listed exemptions | Entries Feb 24 – Jul 23, 2026; terminated by law 12:01 a.m. EDT Jul 24, 2026 |
| Section 301 forced labor (2026) | 12.5% China, 10% India, 10% net-of-MFN EU (final Jul 23, 2026) | Active (entries on or after Jul 24, 2026; in-transit exception through Jul 27; some U.S. note 52 chemical exemptions are pharmaceutical-use-only) |
| Section 301 excess capacity (2026) | None proposed | Investigation open; no proposed action |
Current Chinese botanical examples range from 7.5 percent for green tea at 0902.10.90 to 43.5 percent for chilled or frozen ginseng at 1211.20.15 across MFN and the two Section 301 layers. The common extract lines 1302.19.91 and 1302.19.41 total 20 and 21 percent. During the closed Section 122 window, those extract and ginseng examples instead totaled 17.5, 18.5 and 41 percent. An exemption from the new layer does not erase older China duties. These examples exclude other duties and fees; they should not be used as a rate for every botanical.

India Sourcing: Relief and Disruption
A February 2026 framework trade deal was announced as cutting tariffs on Indian imports from 50 percent to 18 percent (NutraIngredients, February 4, 2026). That 18 percent rate is no longer operative: it rode Executive Order 14257, and Executive Order 14389 (91 FR 9437, February 25, 2026) ended the IEEPA duties imposed under that order. Indian-origin ingredients now carry MFN duty (Free or 1 percent on the common extract lines 1302.19.91 and 1302.19.41; Free on turmeric at 0910.30.00, dried medicinal plants at 1211.90.89 and gum resins at 1301.90.91) plus the 10 percent forced-labor Section 301 duty on covered lines for entries on or after July 24, 2026. For brands sourcing turmeric, ashwagandha, or boswellia from India on those lines, today's duty stack is lower than either the 50 percent peak or the framework's announced 18 percent.
The same February 2026 reporting flagged a complication. Shaheen Majeed, global CEO and managing director of Sabinsa, said Indian farmers had begun moving from supplement-essential crops to crops less affected by tariffs, and that those decisions were based on planting cycles that span months or even years. The crops he named are turmeric, black pepper, amla, and ashwagandha (NutraIngredients, February 4, 2026). Psyllium husk and boswellia sit in a different bucket: AHPA said it had been working with U.S. federal agencies and the Embassy of India on tariffs on those, which is not the same as farmers moving away from them.
Lower duties do not automatically mean normal supply. Availability depends on planting cycles, and Majeed said a tariff reduction could help “but it won’t be immediate.” Brands sourcing these ingredients from India should confirm current availability and lead times directly with their suppliers.
How Tariff Pressure Is Affecting Product Quality
Tariff costs can also create quality pressure. In NutraIngredients reporting (January 9, 2026), a supplier executive used the term “skimpflation” for brands reshaping product formulas as tariff costs rose. The article gives turmeric at 20 percent versus 95 percent curcuminoids as an example. It does not establish a health-benefit comparison between those concentrations.
Separately, NutraIngredients (March 3, 2026) reported that a company's testing of some 44 popular supplements sold on Amazon in the prior year found that roughly half failed to meet basic label accuracy standards. These are the company's reported sample results. They do not establish a market-wide failure rate or show that tariffs caused the label failures.
When your manufacturer changes ingredient sources to manage tariff costs, the risk is not just price. It is potency, purity, and whether the new source passes the same identity testing and COA standards as the original. As Robert Marriott, then director of regulatory affairs at the American Herbal Products Association, put it, “Many companies in many industries, dietary supplements and elsewhere, are going to have to make difficult, sometimes impossible, decisions about price of their products, their ability to continue in business and what options they have in terms of sourcing” (SupplySide, April 17, 2025).
This is why independent verification matters more in a high-tariff environment. If your manufacturer is switching suppliers, ask for fresh Certificates of Analysis from a third-party lab, not just the new supplier's documentation.
How Manufacturers Are Adapting
According to May 2025 NutraIngredients reporting, the U.S. supplement industry imports 80 percent of its raw ingredients from China. AHPA describes many essential botanicals as not available domestically, now officially recognized as “unavailable natural resources” (SupplySide, December 19, 2025). So how are companies responding?
- Selling to new markets: NutraIngredients reported that 2025 tariffs pushed supplement companies to diversify by selling to more overseas markets, especially Southeast Asia.
- India duty drop: the February 2026 framework deal's announced 18 percent rate was terminated with the IEEPA duties it rode (Executive Order 14389, 91 FR 9437, February 25, 2026), and Indian-origin ingredients now enter at MFN duty plus the 10 percent forced-labor Section 301 duty on covered lines. A covered line from China carries 12.5 percent plus any older Section 301 duty instead.
- Speed depends on preparation: Cepham CEO Anand Swaroop said companies that maintain supplier relationships can pivot within 60 to 90 days, while those who abandoned Indian sourcing entirely face 6 to 12 months to re-qualify suppliers and rebuild trust.
- Margin compression: Suresh Lakshmikanthan of Natural Remedies said most companies had been absorbing the 2025 tariff costs, resulting in 40% to 60% margin declines. That is one executive's account, not a measured industry figure.
- Inventory buffers: one mushroom-ingredient supplier said it did not have the capacity, financing or warehousing to pull six to 12 months of inventory forward as large retailers could.
Source: NutraIngredients, January 2026 and February 2026 reporting.
Real example: Whey Protein Isolate
Whey protein isolate reached $11 per pound, or $24,250 per metric ton, a level “never seen before in the market,” Vesper reported on 20 November 2025. U.S. producers had already sold forward well into 2026, and Vesper ties the shortage to demand from GLP-1 medication users. If your formulation depends on whey, budget for current spot prices, not historical averages.
What Brands Can Responsibly Infer
Operational implications for brand owners:
- Rebuild landed-cost models at the SKU level rather than applying a single tariff percentage across an entire ingredient catalog.
- Ask manufacturers and suppliers to identify the HTS code and declared country of origin for the materials that drive the most margin risk.
- When you qualify alternate suppliers, preserve fresh COAs, identity testing, and documented change control so cost pressure does not weaken quality controls.
- Confirm the Section 122 surcharge dropped off your entries dated July 24, 2026 or later, and price in the forced-labor Section 301 duties that apply to entries from that same instant (10-12.5% tiers; vitamins and many mineral salts are exempt as entered under U.S. note 52, while pharmaceutical-use-only chemical lines are covered for supplement use).
- Check whether an active China Section 301 product exclusion covers your HTS line; those exclusions run through November 9, 2026.
Quality control reminder: If you change ingredient suppliers or origins, refresh your lot-level review, COA checks, and any required identity or stability work before assuming the new source is equivalent.
Questions to Ask Suppliers Now
- What HTS code and declared country of origin are you using for this material today?
- Which of your core inputs are currently sourced from China, and which have active non-China alternatives?
- Now that the Section 122 surcharge terminated on July 24, 2026, how quickly will your pricing reflect its removal?
- If you switch source countries, what new testing, documentation, or change-control steps will you complete before release?
- Which of your inputs carry the forced-labor Section 301 duty, and which U.S. note 52 exemptions, if any, do you claim at entry?
