Describe your product and add a photo if you have one. CrossbordIA applies the General Interpretative Rules (GIRs) in the official order, quotes the notes and explanatory notes word for word, and stops to ask you the precise question when a fact is missing. Never a guessed code.

Women's or girls' dresses — of other textile materials — of silk or silk waste

“Is a knit visible?” — No. The photo settles what can be seen; the material comes from your declaration.
GIR 1: heading 62.04, women's dresses. Note 1 to Chapter 62: “… excluding knitted or crocheted articles”. GIR 6: 6204 49 then 6204 49 10, declared composition 100% silk.
Ruled out: the declared composition (100% silk) does not match the wording.
An engine that follows the official method of the Harmonized System: GIRs applied in order, section and chapter notes read first, explanatory notes (HSEN and CNEN) quoted word for word.
Description, composition, gender, country of origin: classification rests on what you declare. The mandatory reference is the item's key; neither it nor the trade name determines the code.
A photo can settle a visible property: knitted or woven, which side the fastening is on. It never establishes the material, the weight or the use. If it does not show the item described, it is set aside and you are asked the question.
As soon as a code is final, a PDF quotes word for word the GIRs, notes and explanatory notes applied, with each fact used and its source. It is neither a BTI nor legal advice.
When the texts require a fact that is missing, CrossbordIA stops at the right level and asks you the precise question, quoting the text behind it and the codes in play.
Your product sheet says woven, the photo shows a knit? Classification stops and asks you to decide. No contradiction is settled without you.
Classification resumes automatically at the level where it stopped, without replaying everything. An answer can be cancelled. Answers, resumptions and supporting documents cost no credits.
Classification confirmed by EU classification regulations when your item matches one exactly; free access to the 723 regulations in force. The code is never changed automatically.
For the EU, the United Kingdom, the United States, Norway and Canada, the product sheet shows the published rate with its official source and date. No amount is calculated.
When a text requires information your product sheet does not give, the engine does not choose for you. It stops at the level concerned and asks you a closed question, with the exact quotation that justifies it.
Your answer is enough: classification resumes where it stopped, without replaying the rest and with no extra credit. The same fact comes up across a whole range? Save the answer for your other items.
Two codes remain in play: 8421.29.00.40 and 8421.29.00.65. Text: “Hydraulic fluid power filters, rated at 1,000 kPa or greater”.
“Is the filter a hydraulic fluid power filter, rated at 1,000 kPa or greater?”
The code 8421.29.00.40 is retained. Your answer appears in the supporting document with its source: “customer answer”.
✓ Automatic resumption at the stop level · no extra credit
CrossbordIA does not stop at a code: it shows its reasoning level by level. GIRs, section and chapter notes, Harmonized System explanatory notes (HSEN) and Combined Nomenclature explanatory notes (CNEN) are quoted word for word, with the facts used and their source.
You always know why a code was retained, and why its neighbours were ruled out. Enough to answer the authorities with texts, not impressions. You can also browse the customs nomenclature section by section and chapter by chapter.
