Marketing Claims and Tariff Classification: A Hidden Source of Duty Exposure
In today’s global trade environment, importers, customs brokers, and compliance professionals focus heavily on sourcing, landed cost, and supply chain efficiency. Yet one often-overlooked factor can significantly impact tariff classification, customs compliance, and duty exposure: how a product is described and marketed.
While marketing claims do not determine tariff classification on their own, they can influence how U.S. Customs and Border Protection (CBP), and the courts evaluate a product’s essential character, principal function, and intended use. When marketing and classification positions are misaligned, companies may face increased duties, audits, or denied refunds.
In this article, we examine how tariff classification is determined by the totality of the evidence —not just product specifications. We explore why marketing claims must align with classification positions, how primary function continues to control most classification outcomes, and why duty-saving programs demand concrete documentation — not just intent. We also examine the procedural risks that can quietly erode value, including how missed deadlines can permanently bar otherwise valid refund claims.
Understanding Tariff Classification Under the HTSUS
Tariff classification in the United States is governed by the General Rules of Interpretation (GRIs) of the Harmonized Tariff Schedule of the United States (HTSUS), which provide a structured framework for determining how goods should be classified. Under GRI 3(b), when goods are composed of multiple materials or components, classification is based on the component that imparts the “essential character.” This analysis is not limited to quantitative factors such as weight or value; it also includes qualitative considerations, including how the product’s function, role in use, design, and consumer perception.
For importers, this means tariff classification is not just a technical exercise — it is a fact-driven analysis of what the product is and what it does. In other words, your marketing team may be affecting your duty exposure, whether you realize it or not.
The Home Depot Doorknob Case: A Key Lesson in Classification Strategy
A leading case decision illustrating these principles is Home Depot U.S.A., Inc. v. United States, 427 F. Supp. 3d 1278 (Ct. Int’l Trade 2020), where the U.S. Court of International Trade (CIT) addressed the proper classification of imported door hardware. The central issue was whether the product should be classified as a lock (typically subject to higher duty rates) or as a door hardware component primarily designed to allow passage (often carrying lower duty exposure).
Mollie Sitkowski, counsel for Home Depot U.S.A., Inc. in the above-styled case, has discussed on the Simply Trade Podcast that the essential character analysis considers both quantitative and qualitative factors, including how a product is marketed and why consumers purchase it.
When conducting a comprehensive essential character analysis, the court evaluates: a) physical construction and components; b) relative weight and value; c) functional design; and d) intended use. The court ultimately held that the doorknob component imparted the essential character, emphasizing that the primary function of the product was to allow users to open and close doors, while the locking mechanism was secondary.
A critical, but often misunderstood, aspect of the Home Depot decision is the role of marketing materials. The court reviewed product descriptions, packaging, and marketing language as part of the overall record. However, marketing was considered but not determinative; it did not independently resolve the classification issue, and the court found it did not clearly favor either classification.
Mollie Sitkowski further stated that following the decision in this case, many importers have sought to reduce or eliminate duties through, amongst others, Chapter 98 HTSUS provisions, including actual use provisions and certain specialized programs (such as those implementing the Nairobi Protocol. These provisions can generate substantial savings, sometimes in the millions, but they come with strict evidentiary requirements.
To qualify, importers must provide verifiable post-importation use documentation, certifications and supporting records consistent with regulatory requirements. Marketing materials may support an intended use argument, but they are not sufficient on their own. In fact, inconsistent marketing can raise red flags and jeopardize eligibility.
Why This Matters for Importers: Duty Exposure Risks
Even though marketing does not control tariff classification, it can still influence how CBP and courts interpret:
The primary function of the product
The intended use in commerce
The reason consumers purchase the product
Marketing representations can reinforce, or undermine, these arguments. From a customs compliance and risk management perspective, inconsistent messaging can create risks. For example, emphasizing a secondary feature in marketing may weaken a classification position. Conversely, consistent and accurate product descriptions can strengthen defensibility during audits or disputes.
For companies importing at scale, even small classification changes can result in significant increases in import duties. Common risk scenarios include: a) products marketed for one purpose but classified under another; b) technical specifications that contradict marketing claims; and, c) inconsistent product descriptions across invoices, websites, and packaging. These inconsistencies can trigger CBP audits and Requests for Information (CF-28s), Notices of Action (CF-29s), and reclassification and retroactive duty assessments.
Country of Origin and Substantial Transformation
Beyond tariff classification, similar issues arise in country-of-origin determinations, which affect duty rates, trade remedies, and eligibility for preferential programs.
CBP applies the substantial transformation test, asking whether a product undergoes a change in name, character, or use. While marketing does not control origin, it can provide context, particularly where the intended use of the product is relevant to the analysis.
Protecting Refund Opportunities: Protests and PSCs
Even where an importer has a strong tariff classification position, procedural compliance is critical to securing duty refunds. Key Deadlines and Mechanisms:
Filing protests within 180 days of liquidation for liquidated entries; or
Submitting Post-Summary Corrections (PSCs) for unliquidated entries
In certain situations, importers may file protective protests while related litigation is pending. However, this strategy must be carefully evaluated based on the specific facts and merchandise at issue. Failure to act within required timeframes can result in the permanent loss of duty refund opportunities.
A Strategic Approach to Customs Compliance
Tariff classification, customs valuation, and origin determinations are no longer siloed compliance tasks; they are strategic business issues that can materially impact the bottom line. A proactive review of product descriptions, marketing materials, and classification rulings and positions can help companies reduce duty exposure, strengthen compliance with CBP requirements, and identify opportunities for duty savings.
The takeaway from Home Depot is not that marketing controls tariff classification — it does not. Rather, it highlights that CBP and the courts evaluate products based on the full factual record, and marketing is one piece of that analysis. For importers operating in today’s enforcement environment, aligning internal teams — legal, compliance, and marketing — is essential to minimizing risk and maximizing efficiency.
At Imperial Shield PLLC, we guide clients through CBP audits, classification disputes, and enforcement actions, helping to align internal practices with regulatory requirements and defend against adverse determinations. If your company is evaluating tariff classification, responding to a CBP inquiry, or seeking to reduce import duties, contact us. Our approach focuses on identifying risk early, strengthening compliance positions, and positioning clients to minimize duty exposure and potential penalties. In many cases, these issues are only discovered after CBP scrutiny, when options are far more limited.
