ITC Section 337 Order Targets Klein Storage Imports

The ITC Section 337 violation involving Klein Tools changes the import risk profile for certain modular storage products, toolboxes, organizers, component boxes, coolers, and related accessories. Importers and customs brokers must now distinguish covered merchandise, manage an 18 percent bond requirement, and prepare for potentially disruptive enforcement at the border.

What the ITC Determination Means for Klein Tools Imports

The Commission Issued Two Different Remedies

The U.S. International Trade Commission found a Section 337 violation involving claims of U.S. Patent Nos. 11,365,026 and 11,794,952. The affected investigation, No. 337-TA-1409, was brought by Milwaukee Electric Tool Corporation and Keter Home and Garden Products Ltd. against Klein Tools, Inc.

The Commission issued both a limited exclusion order and a cease and desist order. These remedies address different parts of the commercial supply chain.

A limited exclusion order generally directs U.S. Customs and Border Protection to exclude covered articles imported by or on behalf of the named respondent, or its affiliated entities where the order applies. It does not necessarily prohibit every product in the broad category from every manufacturer. Product design, patent scope, respondent identity, and the precise language of the order remain critical.

A cease and desist order generally governs specified conduct within the United States. It can restrict activities involving covered imported articles, including sales, distribution, marketing, or movement of existing inventory, depending on the order's terms. Retail availability alone therefore does not establish that a product may continue to be imported or sold without restriction.

One Patent Issue Remains Pending

The Commission terminated the investigation as to the '026 and '952 patents, but it did not reach a final determination regarding U.S. Patent No. 11,952,167. The target date for that portion of the investigation was extended to November 2, 2026.

This split posture matters operationally. Companies cannot treat the pending patent as if it has already produced an additional exclusion remedy. At the same time, compliance teams should monitor the remaining determination because it could affect product coverage, legal strategy, supply planning, and future import decisions.

How the Exclusion Order and 18 Percent Bond Operate

The Bond Applies During Presidential Review

During the Presidential review period, covered articles may generally be entered under bond if the applicable order permits such entry. For this investigation, the Commission set the bond at 18 percent of entered value. That figure differs substantially from the 63 percent bond recommended earlier in the proceeding.

Importers should not treat the bond as an ordinary customs duty. A duty is a government charge assessed under the tariff and trade-remedy framework. The Presidential review bond is security tied to conditional entry during the review period. Its financial treatment, documentation, and potential consequences depend on the disposition of the order and the conditions governing the entry.

Entered value is the relevant basis for calculating the 18 percent amount. Importers should verify that customs value, related-party adjustments, assists, packing, royalties, and other valuation elements have been addressed correctly before estimating exposure. An inaccurate value can affect both normal duty calculations and the security required for covered merchandise.

Exclusion Risk Extends Beyond Duty Cost

The most significant risk is not the bond itself. It is the possibility that merchandise will be denied entry, detained, or subjected to an admissibility review. A product can have the correct tariff classification and duty rate while still being inadmissible because of an intellectual property exclusion order.

Importers also face commercial consequences that customs duty models may not capture. These can include storage charges, port delays, demurrage, customer shortages, canceled purchase orders, reexport expenses, and inventory imbalances. Distributors and retailers may encounter additional restrictions under the cease and desist order, particularly when handling inventory already located in the United States.

Customs brokers should clearly separate three questions during entry review:

1. Is the merchandise within the product and patent scope of the exclusion order?
2. Is the importer, manufacturer, exporter, or related entity covered by the order?
3. If entry is permitted during Presidential review, has the required bond been arranged and documented?

A tariff classification review alone generally cannot answer these questions.

Compliance Steps for Importers and Customs Brokers

Build Product-Level Controls Before Arrival

Importers should begin with a complete inventory of potentially affected stock keeping units. Relevant records may include model numbers, product descriptions, engineering drawings, photographs, component lists, purchase orders, manufacturer identities, and sourcing relationships. Broad descriptions such as “plastic toolbox” or “storage organizer” are rarely sufficient for an intellectual property scope analysis.

The importer should then map each product to the exclusion order's operative language. Legal counsel may be needed where product design, claim coverage, or noninfringement arguments are disputed. Customs brokers should avoid making unsupported patent conclusions, but they should maintain escalation procedures for entries that match identified manufacturers, brands, models, or product families.

Purchase orders and shipping instructions should also require suppliers to disclose the actual manufacturer and provide accurate model information. Generic invoices, abbreviated descriptions, and inconsistent part numbers can prevent effective customs entry screening.

Coordinate Legal, Brokerage, and Supply Chain Decisions

Trade compliance teams should provide brokers with written entry instructions that identify covered products, potentially covered products, and confirmed exclusions from the product population. Those instructions should explain whether shipments may be entered under bond, held pending review, redirected, or prevented from loading at origin.

Importers should also evaluate inventory already in transit. The date of shipment does not necessarily determine whether merchandise is admissible when it reaches the United States. Entry timing, the effective terms of the remedial order, and instructions from CBP generally control border treatment.

A practical response plan should include:

• Monitoring the November 2, 2026 target date for the unresolved '167 patent.
• Identifying open purchase orders and in-transit shipments involving Klein storage systems.
• Estimating the 18 percent bond requirement using validated entered values.
• Confirming whether the surety can support the required bond exposure.
• Reviewing domestic inventory and sales activity under the cease and desist order.
• Preserving product, entry, valuation, and supplier documentation.
• Establishing an escalation path for CBP detention or exclusion questions.

These controls help prevent routine entry processing from becoming an intellectual property enforcement event with little time for commercial alternatives.

Frequently Asked Questions

What Is an ITC Section 337 Violation?

Section 337 addresses certain unfair practices in import trade, including the importation and sale of articles that infringe enforceable U.S. intellectual property rights. When the Commission finds a violation, it may issue exclusion orders directed at imported merchandise and cease and desist orders governing specified domestic conduct.

The Commission affirmed that Klein had not established the invalidity of the asserted patent claims at issue. It also found the relevant domestic industry requirements satisfied for the '026 and '952 patents and determined that public interest considerations did not counsel against the remedial orders.

Does the Limited Exclusion Order Cover Every Toolbox Imported Into the United States?

No. A limited exclusion order generally applies to covered articles associated with the named respondent and other entities included within the order's terms. It is not a universal prohibition on all toolboxes, organizers, storage containers, component boxes, or coolers.

Scope analysis is product specific. Importers should consider the product design, model, manufacturer, patent coverage, respondent relationship, and exact wording of the order. Similar appearance or use may justify additional review, but it does not by itself establish that a product is covered.

Is the 18 Percent Bond an Additional Customs Duty?

No. The 18 percent amount is a bond based on entered value during the Presidential review period. It is a security requirement associated with conditional importation, not an additional tariff or conventional customs duty.

Importers should keep the bond separate from landed duty calculations and duty drawback analysis. The security may still create a meaningful cash flow or surety capacity burden, especially for high-value or high-volume shipments, but it should not be recorded automatically as an ordinary duty payment.

Can Covered Klein Products Still Be Imported During Presidential Review?

Covered articles may generally be entered under bond during the review period when permitted by the order and applicable customs procedures. For this matter, the Commission established a bond equal to 18 percent of entered value.

Conditional entry does not eliminate compliance risk. Importers should confirm product coverage, coordinate with their customs broker and surety, retain supporting records, and understand the consequences that may follow once the review period ends. CBP may also request information needed to determine whether the merchandise falls within the order.

What Should a Customs Broker Do When an Entry May Be Covered?

The broker should pause routine processing and obtain enough information to identify the product, manufacturer, importer, model, and relevant transaction parties. The broker should compare that information with client instructions and the operative exclusion order controls.

If coverage remains uncertain, the broker should escalate the matter to the importer and appropriate legal or trade compliance personnel. Brokers should document the escalation, avoid unsupported admissibility representations, and confirm bond instructions before transmitting the entry.

Does Retail Availability Mean the Products Are Not Restricted?

No. Products may remain visible online or in physical stores for several reasons, including preexisting inventory, listing delays, products outside the order's scope, or inventory requiring separate legal analysis. A retail listing does not determine admissibility at the border and does not resolve obligations under a cease and desist order.

Importers, distributors, and retailers should base decisions on the applicable remedial orders, product facts, and legal analysis rather than marketplace availability.
