Short answer: You can cite another company’s ruling from U.S. Customs and Border Protection (CBP) as evidence for the code you use under the HTSUS (US Harmonized Tariff Schedule), but it does not bind CBP on your goods. Under 19 CFR 177.9, a ruling letter binds CBP for the transaction it describes, a classification ruling applies only to articles identical to the sample or description in it, and other people are told not to rely on it for different transactions. A ruling issued to you is worth the wait when the classification is a close call, the duty difference is material, and you will keep importing the product.
Many importers frame this as “binding ruling vs CROSS ruling”. The two terms do point at different things, but not because CBP issues two kinds of ruling, and mixing them up leads to bad decisions both ways: treating a stranger’s ruling as a shield, or waiting on a request when an identical-goods ruling already settles the question. Below: what the two terms mean, who a ruling binds, what it protects, and how to decide.
Is a CROSS ruling different from a binding ruling?
Yes, for the person reading it, although CBP does not issue two kinds of ruling. CROSS (the Customs Rulings Online Search System at rulings.cbp.gov) is CBP’s searchable database of its rulings, with a Headquarters collection and a New York collection going back to 1989. It is a library, not a type of ruling. “CROSS ruling” is an informal name for a published ruling someone finds there, which almost always means a ruling issued to another company. “Binding ruling” is the everyday name for a ruling letter that CBP issues to the person who asked for it under 19 CFR Part 177.
The two terms exist because the same letter has a different legal effect depending on whose it is. Under 19 CFR 177.9(a), a ruling letter is CBP’s official position on “the particular transaction or issue described therein” and binds CBP personnel until it is modified or revoked. For the holder, meaning the company that requested it and the goods described in it, that letter is a binding ruling. For everyone else it is guidance. Section 177.9(a) allows its principle to “be cited as authority in the disposition of transactions involving the same circumstances”, but 177.9(c) says no person other than the one it was addressed to should rely on it or assume its principles will apply to any other transaction. Another importer can use the letter to support a classification; it cannot treat the letter as its own binding ruling.
| Question | A ruling issued to you (your binding ruling) | Another company’s ruling found in CROSS |
|---|---|---|
| Who asked for it? | You, under 19 CFR Part 177 | Another importer, broker or manufacturer |
| Does it bind CBP on your entries? | Yes, for goods that match the facts and description in the letter (177.9(a) and (b)) | No |
| If CBP changes its position? | Section 177.9(c) lets CBP change it without notice to anyone except you, the addressee, unless the public process applies | You hear of a change only if it goes through the public Customs Bulletin process under 19 USC 1625(c) and 177.12 |
| How you use it | Classify and enter under it; keep the ruling number in your records | Evidence of reasonable care when your goods are identical; a guide to the facts CBP weighs when they are not |
Every ruling in CROSS is binding on someone: the NY ruling you found binds CBP for the company that requested it, on the goods it describes. The way to get a ruling that binds CBP for your goods is to request your own, as described below. Once CBP issues and publishes it, your binding ruling becomes another reader’s “CROSS ruling”.
Who does a CBP ruling bind under 19 CFR 177.9?
A ruling binds CBP, for the specific transaction it describes, until CBP modifies or revokes it. Section 177.9 sets out the limits in three steps:
- Section 177.9(a): a ruling letter is CBP’s official position on “the particular transaction” and binds CBP personnel until modified or revoked.
- Section 177.9(b)(1) and (b)(2): the ruling assumes the facts submitted were accurate and complete, field offices check that the goods match, and a tariff classification ruling applies only to articles “identical to the sample submitted” or matching the description in the ruling.
- Section 177.9(c): unless the notice-and-comment rules of 177.12 apply, CBP can modify or revoke a ruling without notice to anyone “other than the person to whom the ruling letter was addressed”, and others should not rely on it for transactions other than the one described.
So a ruling on your exact product, issued to you, binds CBP on your entries of that product. A ruling issued to another importer does not bind CBP on your entries at all, even for identical goods. CBP does tend to classify identical goods consistently, and 19 USC 1625(c) (below) gives importers of substantially identical goods notice when CBP changes its view, but neither is a right you can enforce on the strength of someone else’s letter.
Can you rely on another importer’s CBP ruling to show reasonable care?
Yes, and that is the main value of other people’s rulings. The importer of record must use reasonable care to classify goods (19 USC 1484), and a documented match to a current CBP ruling on identical goods is strong evidence of that care.
The protection depends entirely on the facts. If your bottle has the same double-walled vacuum construction as the one in the ruling, the ruling supports you. If yours has a foam-filled wall, a built-in speaker or a different material, the ruling describes a different product and supports nothing. Even with a good match, someone else’s ruling does not stop CBP from reclassifying your entries and collecting the higher duty when it liquidates them. If CBP finds a violation of 19 USC 1592, section 1592(d) also requires restoration of the lost duties whether or not a penalty is assessed. What a matching ruling helps with is the culpability question, because it is hard to call an importer negligent for following CBP’s own published reasoning on identical goods.
Penalty exposure depends on the full facts of each case. If CBP has already questioned a classification, involve a licensed customs broker or trade attorney before you rely on any ruling in a response.
What is the difference between NY and HQ rulings?
NY rulings come from the National Commodity Specialist Division in New York, which issues most tariff classification rulings on prospective imports. HQ rulings come from Regulations and Rulings in CBP’s Office of Trade at Headquarters, which handles harder questions, internal advice and protest reviews. Under 19 CFR 177.2(b)(2)(ii)(C), Headquarters “retains authority to independently review all tariff classification ruling letters”, and it uses HQ rulings to modify or revoke NY rulings.
Both bind CBP for the transaction described. For research, an HQ ruling usually carries more weight because it often settles a disputed point and may expressly revoke earlier NY rulings. The vacuum bottle rulings are an example: four NY rulings had placed stainless steel vacuum bottles in heading 7323, and HQ H303684 (July 7, 2021) revoked all four and moved the goods to heading 9617.
When is a ruling of your own worth requesting?
Request your own ruling when the existing rulings do not cover your facts and getting the answer wrong would be expensive. CBP’s National Commodity Specialist Division says it generally issues classification rulings within 30 days, and requests referred to Headquarters take longer, so build the wait into the product launch. The table gives typical situations.
| Situation | Usual decision | Why |
|---|---|---|
| Current ruling on goods identical to yours, not modified or revoked | Rely on it and file it in your records | Strong evidence of reasonable care; a new request adds little |
| Rulings on similar goods, but yours differ in material, function or presentation | Request your own if the duty difference is material | The difference may change the heading, and no ruling covers it |
| Conflicting rulings, or an old NY ruling never confirmed by HQ | Request your own | You need CBP’s current view on your facts |
| New product with no close ruling | Request your own before the first shipment | Rulings are prospective; after entry the chance is gone |
| Large, repeating volume with a big rate gap between candidate headings | Request your own even if you are fairly confident | Certainty on future entries is worth 30 days |
| One-off shipment, low value | Rely on research and document it | The wait and effort outweigh the duty at stake |
When can you not get a ruling?
CBP issues rulings only on prospective transactions, meaning goods that have not yet arrived or been entered (19 CFR 177.1(a)(1)). It will not rule on a completed transaction, on an essentially hypothetical question, or on an issue pending before the Court of International Trade or the Federal Circuit (19 CFR 177.7(a) and (b)). And 19 CFR 177.2(b)(5) requires every request to say whether the same transaction has been, or is being, considered by any CBP office or by those courts.
The limit bites hardest when CBP has already questioned your classification. A ruling request cannot resolve a live CBP Form 28 (CF-28, Request for Information) on entries you have already made, because those entries are no longer prospective. An entry still before the port is a “current” transaction, which the port decides itself or refers to Headquarters as internal advice (19 CFR 177.1(a)(2)(i)). A liquidated entry is a “completed” transaction and cannot be the subject of a ruling request at all (177.1(a)(2)(ii)). You can still ask for a ruling on future imports, but the request must disclose the open inquiry, and the ruling will not decide the past entries. The tools for a dispute about entries already made are different:
- Answer the CF-28 with your classification analysis.
- Ask the port to seek internal advice from Headquarters on a current transaction where you and the port disagree (19 CFR 177.11).
- After liquidation, file a protest within 180 days (19 USC 1514).
Headquarters may decline an internal advice request when considering it would hold up action on the transaction and the question can be raised later in a protest (19 CFR 177.11(b)(5)), so the protest is often the route in the end.
How do revocations and modifications affect you?
CBP can change its mind about a ruling, but for any ruling in effect for 60 days or more it must do so in public. Under 19 USC 1625(c), a proposed modification or revocation, or a proposed change to the treatment CBP has given substantially identical transactions, is published in the Customs Bulletin with at least 30 days for comment. The final notice follows within 30 days after comments close, and the change takes effect 60 days after the final notice is published. CBP’s regulation, 19 CFR 177.12, adds that a claim of prior treatment needs evidence of consistent national treatment over a two-year period.
The vacuum bottle case shows the timeline. CBP published the proposal to revoke four NY rulings in the Customs Bulletin of March 10, 2021, with comments due April 9, 2021. It considered the comments and issued HQ H303684 on July 7, 2021, effective 60 days after the final notice. Anyone relying on those NY rulings, whether they held them or simply followed them, had those months of warning, and anyone checking the Customs Bulletin would have seen it coming. A proposal can also fail: an earlier 2015 proposal to revoke two of the same rulings was never finalized.
What mistakes do importers make with rulings?
- Citing a ruling on “similar” goods without writing down where the facts differ.
- Relying on a NY ruling that an HQ ruling has since revoked.
- Treating someone else’s ruling as protection against duty adjustments; it is evidence of care, not a bar to reclassification.
- Asking for a ruling to settle a dispute about past entries; rulings cover prospective transactions only (19 CFR 177.1(a)).
- Changing the product (a new material, an added function) and keeping the old ruling on file as if it still applied.
Most of these come down to comparing facts. TariffWolf helps with that comparison: for each product it returns the 6-digit HS code together with the CBP (CROSS) and EU rulings it relied on, so a classifier can read the closest rulings against the product facts, decide whether an existing ruling fits or a request is needed, and choose the last four digits of the HTS line.

Frequently asked questions
Is a CROSS ruling different from a binding ruling?
Yes, in practice. CROSS is CBP’s searchable database of rulings, and “CROSS ruling” is an informal name for a published ruling found there, usually one issued to another company. That ruling binds CBP only for the holder’s transaction (19 CFR 177.9); you can cite it as guidance but cannot rely on it as your own binding ruling. To get one that binds CBP for your goods, request your own under 19 CFR Part 177.
Are CBP rulings binding on other importers?
No. A ruling binds CBP for the transaction it describes (19 CFR 177.9). Other importers can cite it as evidence of how CBP classifies identical goods, but CBP is not bound by it on their entries.
Does a CBP ruling protect me from penalties?
A ruling on goods identical to yours is strong evidence that you used reasonable care, which is relevant to penalties under 19 USC 1592. It does not stop CBP from reclassifying your entries and collecting the duty difference. If your goods differ from the ruling’s facts, it offers little support.
Can I request a ruling while CBP is reviewing my entries?
Only for future imports. Rulings cover prospective transactions (19 CFR 177.1(a)), so entries already made are outside them, and your request must disclose the pending CBP review under 177.2(b)(5). The dispute over past entries goes through the CF-28 response, internal advice or a protest.
Start by looking for a current ruling on identical goods. If your facts match, file it and move on. If the rulings conflict, describe different goods or predate a heading change, and the duty at stake justifies it, ask CBP for your own before the goods ship.
For catalogs where that check has to happen SKU by SKU, TariffWolf’s bulk classification service returns the 6-digit HS code for each product with the rulings and notes behind it. Your team or broker then sets the full HTS line and can see which products an existing ruling already covers and which may need a request. You can send a sample file of difficult products through the contact page and review the citations first.
