Section 625 Notice-and-Comment
/ˈsɛkʃən ˈsɪks hʌndrəd ˈtwɛnti faɪv ˈnoʊtɪs ænd ˈkɒmɛnt/
Section 625 of the Tariff Act of 1930, as amended (19 U.S.C. § 1625), establishes a mandatory notice-and-comment procedure that U.S. Customs and Border Protection must follow before it modifies or revokes a binding ruling letter or any ruling on which importers have relied. CBP must publish the proposed change in the Customs Bulletin and allow interested parties at least 30 days to submit comments before the new position becomes effective. The procedure protects importers from sudden retroactive classification changes and underpins the principle of informed compliance across the trade community.
In Detail
The statutory authority for Section 625 notice-and-comment is 19 U.S.C. § 1625(c), which provides that CBP may not modify or revoke a ruling letter, or take any action that has the effect of modifying the treatment previously accorded to substantially identical transactions, unless it first publishes notice of the proposed action in the Customs Bulletin. The notice must identify the ruling(s) at issue, articulate CBP's legal reasoning for the proposed change, and invite written comments from any interested party within a period of not less than 30 days. Only after that comment period closes — and after CBP considers the comments received — may the agency publish a final notice giving effect to the modification or revocation.
In practice, Section 625 applies to three main scenarios: (1) prospective revocation or modification of a specific binding ruling letter issued under 19 C.F.R. Part 177; (2) 'treatment' revocations, where CBP changes its position on the classification or valuation of goods it has consistently liquidated in a particular manner, even absent a formal ruling; and (3) court decisions or administrative determinations that compel CBP to alter its longstanding practice. The 30-day comment window gives importers, customs brokers, and trade associations an opportunity to submit evidence, argue legal points, or provide commercial data that may influence the final agency position — a genuine, if compressed, notice-and-comment process modeled on APA principles but embedded directly in customs law.
A critical edge case involves 'treatment' without a formal ruling. Importers sometimes assume that because they never requested a binding ruling, Section 625 does not protect them. CBP's regulations at 19 C.F.R. § 177.12(c)(1) extend protection to any importer who received a ruling or whose goods were 'treated' consistently by CBP for a period of time. If CBP attempts to reclassify such goods without going through the Section 625 procedure, the importer may challenge the change as procedurally defective. However, Section 625 does not protect against prospective changes that result from judicial decisions interpreting the HTSUS, and it does not bar immediate action in cases of fraud or national security concerns.
Classification Significance
Importers who are unaware of Section 625 protections face serious audit exposure: if CBP purports to reclassify goods without following the notice-and-comment process, entries liquidated under the old classification may be re-liquidated under a higher-duty provision, generating unexpected duty liability that can stretch back months or years. Conversely, importers who ignore a published Section 625 notice forfeit their right to comment and lose the most powerful procedural moment to challenge a classification change before it becomes binding. Trade competitors who do participate in notice-and-comment can shape the final ruling in ways that affect their rivals' landed costs, making active monitoring of the Customs Bulletin a competitive intelligence function as much as a compliance one. Missing a Section 625 comment deadline also weakens any subsequent CBP protest or Court of International Trade challenge, because courts look favorably on parties who exhausted the administrative record.
How Kanon Handles This
Kanon's corpus continuously indexes the Customs Bulletin for new Section 625 notices, linking each proposed modification or revocation to the underlying ruling letters and HTSUS headings already tracked in the platform. When Kanon generates a Classification Support Package for a product, it flags any open or recently closed Section 625 comment periods affecting the relevant subheadings, so importers and brokers know whether the classification landscape may be shifting. Because Kanon's GRI traversal engine documents the full legal reasoning chain — from GRI 1 through applicable chapter notes and section notes — the package also provides a ready-made evidentiary foundation that can be submitted as a Section 625 comment, giving users a head start on protecting their classification position before CBP finalizes any adverse change.
Frequently Asked Questions
If CBP reclassifies my goods without publishing a Section 625 notice, can I challenge the re-liquidation?
Yes. You can file a CBP protest under 19 U.S.C. § 1514 arguing that the reclassification is procedurally invalid because CBP failed to comply with 19 U.S.C. § 1625(c). Courts have held that skipping the notice-and-comment requirement renders the new position unenforceable against importers who relied on the prior ruling or consistent treatment. Document your reliance — prior ruling letters, entry records showing consistent liquidation, and any correspondence with CBP — to support the procedural defect argument.
Does Section 625 protect me if I never requested a formal binding ruling but CBP has always liquidated my goods at a certain rate?
Potentially yes. Under 19 C.F.R. § 177.12(c)(1), 'treatment' afforded by CBP — meaning consistent, repeated liquidation of substantially identical merchandise under the same tariff provision — can trigger Section 625 protection even without a formal ruling letter. You must be able to demonstrate the consistency of that treatment across multiple entries. The protection, however, is prospective: it requires CBP to follow the notice-and-comment process before changing your classification going forward, but it does not prevent CBP from correcting errors on specific entries still within the statutory liquidation review period.
