U.S. Trade Representative Jamieson Greer finalized a new round of duties under Section 301 of the Trade Act of 1974 on July 23, 2026, imposing new 10% and 12.5% tariff rates on goods from 60 economies accused of failing to impose or effectively enforce bans on imports made with forced labor. The duties apply to most covered imports entered for consumption, or withdrawn from warehouse for consumption, at or after 12:01 a.m. ET on July 24, 2026.
For small business importers, the change creates a new cost layer on top of existing Most Favored Nation rates and, in some categories, other trade remedies. Goods already loaded and in final transit before the effective time receive a short grace period if entered before 12:01 a.m. ET on July 28, 2026, but that narrow window leaves little time for smaller firms to check origin, classification, contracts, and pricing.
The action also shifts the administration’s tariff strategy away from broader emergency authorities that faced legal setbacks earlier in 2026 and toward a more familiar trade statute. That may make the duties more durable than the measures they replaced, but it also makes the compliance picture more technical for importers that do not have in-house customs staff.
USTR uses forced-labor investigations to set new 10% and 12.5% duties
Section 301 allows USTR to investigate and respond to foreign acts, policies, or practices that are unreasonable, discriminatory, or burden U.S. commerce. In this case, USTR framed the investigations around forced-labor import enforcement, arguing that trading partners should adopt and enforce prohibitions comparable to the U.S. forced-labor import ban.
The final action divides the covered economies into several groups. Argentina, Bangladesh, Cambodia, Canada, Ecuador, El Salvador, Guatemala, Honduras, India, Indonesia, Jordan, Malaysia, Mexico, Pakistan, Sri Lanka, Trinidad and Tobago, and the United Kingdom are subject to a 10% Section 301 rate. Goods from the European Union and Taiwan are subject to a net-rate structure that brings the combined MFN and Section 301 rate up to 10% where the MFN rate is below that threshold. Goods from Japan, Korea, and Switzerland are treated similarly, but with a 12.5% combined-rate threshold. For all other investigated economies, the Section 301 rate is 12.5%.
The duties are broad but not universal. USTR exempted informational materials, donations, accompanied baggage, articles already subject to Section 232 tariffs, and additional product categories listed in the Federal Register notice. Those exemptions matter for importers, but they must be applied at the HTS line level rather than by general product description. A product that sounds like it belongs in an exempt category may still be covered if the tariff classification does not match.
Small importers have less room to absorb the new duty layer
The financial effect is straightforward. A 12.5% Section 301 duty on $500,000 in annual imports adds $62,500 in duty exposure before broker fees, freight, warehousing, or working-capital costs. For businesses already operating on thin product margins, that increase can force immediate decisions about price changes, order volumes, supplier negotiations, or product mix.
Large importers typically have more ways to manage sudden tariff changes, including tariff-escalation clauses, diversified sourcing, customs counsel, and enough volume to negotiate with suppliers. Small businesses often rely on fewer suppliers, shorter contract cycles, and more price-sensitive customers. That means the same tariff percentage can create a much sharper operational problem for a smaller importer than for a national retailer or manufacturer.
The rate structure also complicates sourcing decisions. A business importing from Canada or Mexico may face a 10% additional duty, while a similar product from Vietnam or China may face 12.5% plus existing standard duties and any older tariff layers. Shifting suppliers may reduce one tariff exposure while creating another through lead times, quality requirements, minimum orders, or origin-verification costs.
For companies already adjusting to previous tariff announcements, the new duties require another round of landed-cost modeling. Research on how small businesses are responding to tariff pressure shows that smaller firms often have limited capacity to absorb sudden trade-cost changes without passing costs to customers or reducing purchases.
Exemptions and HTS classifications need broker review
The July 23 final notice settled the main rate structure, but it did not make compliance simple. Exemption categories are defined through the tariff schedule and annexes, not through plain-language product descriptions. Importers therefore need to review each affected SKU by origin country and HTS classification before assuming a product is exempt or covered.
USTR also indicated that tariff-rate quotas will be established, when feasible, for certain textile and apparel imports from Bangladesh, Cambodia, Indonesia, and Malaysia based on each economy’s importation of U.S. inputs. Until those quotas are formally implemented, importers should not assume quota relief is available.
The legal theory behind the duties may also generate challenges. Section 301 is a familiar trade tool, but applying it across 60 economies based on forced-labor enforcement failures is a sweeping use of the statute. Any litigation, WTO challenge, or future administrative revision could alter the duty landscape after businesses have already made sourcing decisions. That makes flexibility valuable. Long-term contracts based on a single tariff assumption now carry more risk than usual.
Small businesses should recalculate landed costs before the grace period ends
- Identify the origin country for every active SKU. Pull purchase orders, bills of lading, origin certificates, and supplier records. Prioritize goods already in transit because the grace period applies only to shipments loaded before the July 24 effective time and entered before July 28.
- Recalculate landed costs using the correct rate structure. Apply the 10% rate, the net-rate treatment, or the 12.5% rate based on the origin country and product category. Compare the revised landed cost with current selling prices and customer contracts.
- Confirm exemption status by HTS subheading. Do not rely on broad product descriptions. Ask a licensed customs broker or trade counsel to verify whether each imported item falls within an exempted HTS line or remains covered by the new Section 301 duty.
- Review supplier contracts for tariff adjustment language. Contracts that include change-in-law, tariff pass-through, or force majeure provisions may offer room to renegotiate. Contracts without those clauses may leave the importer absorbing the full increase.
- Document any shipment that may qualify for the transit grace period. Keep bills of lading, airway bills, port-loading records, and entry paperwork together. CBP may require evidence that the goods were loaded and in final transit before the effective time.
- Check whether older exclusions still help. If the business previously relied on a Section 301 exclusion, confirm whether that exclusion remains operative under the expanded action or whether the new country-level duty structure supersedes it.
- Monitor USTR and the Federal Register for implementation updates. If USTR opens an exclusion petition process, filing windows may be short and evidence-heavy. Businesses should identify their highest-impact product lines now rather than waiting until a petition window opens.
- Review refund exposure from earlier emergency tariffs. Importers that paid duties under earlier emergency-based measures should review guidance on IEEPA tariff refunds for small business shippers and confirm who was listed as Importer of Record on CBP Form 7501.
Legal challenges and future tariff actions could shift import costs again
The July 24 duties may not be the last tariff action of 2026. USTR is also pursuing additional trade investigations, including one focused on excess industrial capacity. Small importers with exposure across multiple sourcing regions should not treat the current rate map as stable through year-end.
The forced-labor compliance structure creates a built-in path for rate changes. Countries that adopt or strengthen forced-labor import bans may be able to move into a lower-rate category, while those that do not may remain at the higher rate. USTR has not yet specified a predictable review timetable for those adjustments, which means importers may need to update cost models repeatedly.
The practical lesson for small businesses is not to ignore the tariffs because legal challenges may come. It is to plan for the duties to remain in force while preserving flexibility if rates change. Shorter contract commitments, clear tariff-pass-through terms, and line-by-line classification records will matter more than broad assumptions about where trade policy is heading.
