How to Use the CROSS Database to Search CBP Customs Rulings

To search CBP customs rulings on CROSS, go to rulings.cbp.gov, enter your product’s Harmonized Tariff Schedule (HTS) code and a precise technical description into the advanced search, and read the full text of any ruling that looks close to your product. The database is free, requires no login, and holds rulings going back to 1989.¹ A ruling you find there tells you how CBP has treated a specific product for another importer; it does not automatically protect your shipment, and that distinction shapes how you should use what you find.

What to Gather Before You Search

A useful CROSS search starts with the technical details of your product, not a generic description. The single most important piece of information is the HTS code, which classifies every item imported into the United States. You can search using four, six, eight, or ten digits depending on how narrow you want the results.² Identifying the correct HTS code is also the first step in determining the duty rate for any product.³

Alongside the HTS code, know your product’s material composition, functional purpose, and commercial designation. Classification often hinges on fine distinctions. A garment made from knitted fabric falls under different tariff headings than one made from woven fabric, even if the two products look identical. For chemical products, a CAS number or lab analysis may be needed. For machinery, a description of the device’s principal function in the United States narrows results far more effectively than a brand name or model number.

If you already have a ruling number from a previous shipment or a broker’s records, you can pull that ruling directly. The same is true if you know a competitor received a ruling on a similar product; searching by that number lets you read the full decision and CBP’s reasoning, even though the ruling is not binding on your imports.

Choosing Between Simple and Advanced Search

CROSS offers two search modes. The simple search works like a standard search engine: type a phrase and the system scans the whole database. The advanced search lets you target specific fields inside ruling documents, including the ruling number, HTS classification, issuing office, and date range. For anyone searching regularly, the advanced search is worth learning because it cuts through the noise a simple keyword search generates.

It also helps to know which office issued the ruling. New York rulings come from the National Commodity Specialist Division and address routine classification questions for specific products.⁴ Headquarters rulings come from the Office of Trade’s Regulations and Rulings division and address more complex or precedent-setting issues. When a Headquarters ruling conflicts with a New York ruling on the same product, the Headquarters ruling controls. You can filter by collection in the advanced search to focus on whichever is more relevant to your question.

Boolean Operators and Wildcards

The system accepts Boolean operators to control how search terms relate. AND requires both terms to appear in the ruling. OR returns results containing either term. AND NOT excludes documents containing a specified word or phrase. A NEAR operator finds terms that appear close together, and an asterisk (*) works as a wildcard for alternative word forms and plurals.⁵

Choosing the right operator is often the difference between useful results and a pile of irrelevant rulings. If you import stainless steel fasteners, “stainless AND fastener” returns tighter results than the phrase “stainless steel fastener,” because a phrase search requires those exact words in that exact order. If you want to leave bolts out of a fastener search, “fastener AND NOT bolt” filters them.

Narrowing With Filters

Entering an HTS number into the classification field restricts results to rulings within that tariff category. Six digits captures the broadest set of rulings for a heading; eight or ten digits narrow to a specific subheading or statistical suffix. Format matters here. Trailing zeros and periods can affect whether the system finds a match, so try more than one formatting version if the first attempt returns nothing.

Date range filters help when you want only recent rulings, or when you are tracking how CBP’s position on a product has shifted over time. In the description field, use the formal tariff language CBP itself uses in rulings rather than everyday terminology. “Footwear with outer soles of rubber” pulls better results than “rubber shoes.”

Reading and Saving Your Results

Results display as a list with the ruling number, date of issuance, and a brief summary. The summaries are fine for screening, but do not treat them as substitutes for the full ruling. Click through to see the complete product description, CBP’s legal analysis, the HTS classification, and any conditions or limitations attached to the decision.

Save or print every ruling you rely on. Federal law requires importers to use reasonable care when declaring the classification, value, and country of origin of their goods.⁶ Keeping copies of the rulings you reviewed, including ones that did not match, documents the work you did. During a customs audit, that paper trail can be the difference between a finding of reasonable care and a finding of negligence.

Checking Whether a Ruling Is Still in Effect

Rulings in CROSS are not permanent. CBP can revoke or modify them, and the process depends on how long the ruling has been in effect. If a ruling is less than 60 days old, CBP can revoke it by notifying the original recipient in writing. For rulings that have been in effect for 60 days or more, CBP must publish a proposed revocation in the Customs Bulletin, allow at least 30 days for public comment, and publish its final decision within 30 days after the comment period closes. The final ruling becomes effective 60 days after publication.⁷

A ruling you found in CROSS last year could be revoked today. Anyone eligible to request a ruling can write to CBP to ask whether a specific ruling has been modified or revoked.⁸ If your import strategy leans on a particular ruling, confirming it is still current before each major shipment is a basic precaution.

Why Another Importer’s Ruling May Not Protect You

This is where many importers make a costly assumption. A ruling letter is legally binding only on the person who requested it and only for the specific transaction described in the letter. Federal regulations explicitly state that no other person should rely on a ruling letter or assume its principles will apply to a different transaction.⁸

In practice, CROSS rulings on similar products are persuasive and useful for building your classification rationale. Customs officers know them and generally apply consistent principles. But if CBP classifies your shipment differently from a ruling issued to someone else, you cannot point to that other ruling as a legal defense. The only way to get binding protection is to request your own ruling through CBP’s electronic ruling portal at erulings.cbp.gov, which routes requests to the National Commodity Specialist Division in New York.⁴ Ruling requests can cover only prospective transactions; you cannot request a binding ruling for a shipment already arrived or already under review at a port.⁹ NCSD generally issues rulings within 30 calendar days of a complete request, with more complex referrals to Headquarters typically taking up to 90 days.

What Misclassification Costs

Good CROSS research is not an academic exercise. Importers who misclassify goods face civil penalties that scale with culpability under federal law:¹⁰

Negligence: up to the lesser of the domestic value of the merchandise or two times the unpaid duties.
Gross negligence: up to the lesser of the domestic value or four times the unpaid duties.
Fraud: up to the full domestic value of the merchandise.

Importers who catch a misclassification themselves and disclose it to CBP before a formal investigation begins can reduce these penalties significantly. For negligence and gross negligence, a prior disclosure caps the penalty at interest on the unpaid duties rather than a multiple of the full amount. Clerical errors and system glitches are not treated as violations unless they form a pattern of negligent conduct.

Thorough CROSS research supports a defense that you exercised reasonable care, which is the standard federal law imposes on every importer making entry.⁶ If CBP challenges your classification, being able to show that you searched CROSS, reviewed comparable rulings, and applied their reasoning to your product is often what keeps a misclassification from escalating into a negligence finding.
