60-Day Comment Period (Ruling Revocation)
/ˈsɪksti deɪ ˈkɒmɛnt ˈpɪriəd ˈruːlɪŋ ˌrɛvəˈkeɪʃən/
The *CBP Ruling Modification and Revocation Procedure* is a statutory safeguard under 19 U.S.C. § 1625(c) governing changes to certain interpretive rulings or decisions and qualifying treatments. For a change governed by this provision, U.S. Customs and Border Protection (CBP) publishes a *General Notice of Proposed Modification or Revocation* in the Customs Bulletin and allows at least 30 days for public comment. After considering all timely comments, CBP publishes a final decision; under 19 C.F.R. § 177.12, this final decision ordinarily becomes effective 60 days after its publication, providing an effective-date delay rather than a comment period.
In Detail
The statutory basis is 19 U.S.C. § 1625(c), implemented through 19 C.F.R. § 177.12. This procedure applies when CBP determines that an interpretive ruling or decision (such as a ruling letter on classification or country of origin) or a "treatment" (defined in § 1625(c)(2) as a consistent application of an interpretation of law to a specific importer over two years, resulting in reliance) is legally incorrect. Instead of immediately issuing a corrective ruling, CBP must publish a proposed change in the weekly *Customs Bulletin*, identify the ruling(s) or treatment(s) to be modified or revoked, explain its legal reasoning, and invite written comments for at least 30 calendar days. This process ensures stakeholders receive advance notice and an opportunity to respond.
In practice, the 30-day comment window begins on the date the notice appears in the Customs Bulletin. Any person may submit written comments to the National Commodity Specialist Division or Headquarters Office of Regulations and Rulings, as appropriate. CBP is not legally bound to adopt commenters' positions, but it must consider timely submissions before finalizing the revocation or modification. After the comment period closes, CBP reviews any submissions and then publishes its final decision. This final decision ordinarily becomes effective 60 days after its publication, giving importers time to adjust their entry practices, supply chains, and bonded merchandise before the change is legally binding.
A common misconception is that a proposed revocation notice automatically voids prior entries filed under the old ruling. It does not. Under the 'detrimental reliance' doctrine codified in § 1625(c)(2), importers who relied in good faith on a ruling or treatment prior to the final revocation date retain protections for entries made during that period, provided they meet the reliance criteria. However, once the final revocation is published and the effective date passes, continued importation under the old classification or treatment creates audit exposure and potential 19 U.S.C. § 1592 penalty liability.
Classification Significance
Importers who miss a proposed modification or revocation notice in the Customs Bulletin—or who fail to track the CROSS (Customs Rulings Online Search System) database for rulings affecting their product lines—risk continuing to file entries under a classification or origin determination that CBP has formally changed. Because the proposed change becomes publicly known upon Customs Bulletin publication, CBP and courts treat ignorance of the notice as no excuse; entries filed after the final effective date under the superseded ruling or treatment are subject to duty underpayment claims, interest, and potential fraud or gross negligence penalties under § 1592. Conversely, importers who engage during the 30-day comment window and submit well-documented legal comments have influenced final outcomes, occasionally causing CBP to narrow or withdraw a proposed change entirely.
How Kanon Handles This
Kanon's corpus continuously indexes the Customs Bulletin alongside CROSS rulings, flagging any General Notice of Proposed Modification or Revocation that touches headings or subheadings relevant to a user's product. When Kanon builds a Classification Support Package, it surfaces active or recent modification or revocation proceedings as a risk factor alongside the deterministic GRI traversal, alerting importers and brokers to respond within the 30-day comment window or update their entry practices before the final decision's 60-day delayed effective date—turning what is often an overlooked Federal Register analog into an actionable compliance checkpoint.
Frequently Asked Questions
If CBP proposes to revoke a ruling that I rely on, do I have to stop importing under the old classification immediately?
No. The proposed change does not itself alter your legal obligations. You may continue importing under the existing ruling or treatment until the final modification or revocation is published and its effective date (typically 60 days after final publication) arrives. During the initial 30-day comment period, you should submit written comments if you disagree with CBP's reasoning. Once the final effective date passes, however, you must file entries under the new classification or treatment or risk duty underpayments and § 1592 penalties.
Where are proposed ruling revocations published, and how do I monitor them?
CBP publishes all proposed modifications and revocations in the weekly Customs Bulletin, available free on the CBP website. You can also monitor CROSS for ruling letters that cite 19 U.S.C. § 1625(c). Many brokers set up keyword alerts for relevant HTS headings. Kanon automates this monitoring within its platform, flagging Customs Bulletin notices that affect headings covered by your active classification projects.
