Buyer’s toolkit

Where to check a fact before you order

Four questions decide whether an order makes money, and none of them can be answered by a supplier’s marketing page: which tariff heading the goods fall under, what duty that attracts, what the label has to say, and what a size actually measures. Each has an official source. This page tells you which one to open and when — and what to have in front of you before you open it.

Nothing here is a link exchange. If a link does not answer one of those four questions, it does not belong on this page.

Official sources

Government and inter-governmental sources. Slow to load, ugly to read, and the only numbers worth quoting.

01

USITC — Harmonized Tariff Schedule

What it is
The US tariff schedule: every heading, the duty rate attached to it, and the notes that decide which rate applies.
When you need it
Before you ask for a landed cost on an import, and before you accept the HS code a supplier gives you. This is the source, not a summary of it.
Have this ready
Fibre content (e.g. 100% cotton), knit or woven, garment type, gender, and whether it is a singlet or a t-shirt.

Search by keyword, then read the chapter notes — the notes often change the answer more than the heading does.

CBP CROSS — Customs Rulings Online

What it is
Searchable database of rulings US Customs has issued on real products. If something similar has been ruled on, that ruling is the strongest evidence you can hand a broker.
When you need it
When two people disagree about a classification, or when your product is unusual — a blend, a garment-dyed finish, a lined body.
Have this ready
A plain description of the goods in trade language, plus any similar ruling number you have already found.

A ruling on a similar garment is persuasive, not binding, for your shipment. It is still better than an opinion.

03

CBP — Trade

What it is
Entry requirements, importer obligations, broker licensing, de minimis rules and the forms an entry needs.
When you need it
Your first import, or the first time you consider declaring a value different from the invoice.
Have this ready
Nothing — read first. The undervaluation section is the one to read before anyone suggests it.

Written for importers of record, which is what you become the moment your name is on the entry.

04

European Commission — TARIC / customs tariff

What it is
The EU equivalent: classification, duty rates, anti-dumping measures and import controls by member state.
When you need it
Any shipment landing in the EU. The UK, EU and US do not classify or rate apparel identically.
Have this ready
The same specification list as for HTS, plus the destination country.

If you sell into several EU countries, the rate is the same but the VAT treatment and labelling language requirements are not.

FTC — Business guidance on textile labelling

What it is
The US rules on fibre content, country of origin and care labelling — the document to read is "Threading Your Way Through the Labeling Requirements Under the Textile and Wool Acts".
When you need it
Before you approve a care label or a private-label neck label for the US market. This is the one place where a mistake is a compliance problem rather than a design problem.
Have this ready
The fibre composition of the actual fabric, not the one on the supplier’s marketing sheet.

FTC blocks some non-US traffic, so the page may not open from outside the US. If it does not, ask your US contact to pull the document, or use a US-based browser.

trade.gov — Country Commercial Guides

What it is
Market-by-market guides: import requirements, labelling, standards and distribution practice, written by US commercial staff in each country.
When you need it
Entering a market you have not shipped to. It tells you what will be asked for at the border before you find out the hard way.
Have this ready
The destination country and the product category.

Useful for the questions that are not about duty: labelling, testing, packaging and who the buyers are.

Our own tools

The four things we publish instead of asking you to email us for.

Three rules we apply to this page

We do not publish a duty rate.

Rates depend on classification, origin and the date of import. A rate printed on a supplier page will be wrong within a season. The official schedules above are the only numbers worth quoting.

A ruling beats an opinion.

If your broker and your supplier disagree, the CBP rulings database settles it faster than a phone call, because someone has already had the argument in writing.

External links are checked, not trusted.

Every link on this page was opened on 21 October 2026. Government sites reorganise without warning — if something 404s, tell us and it gets replaced.

Need the number rather than the source?

Send the specification and the destination. You get a unit price with the basis stated, and the freight and duty shown as separate lines instead of folded into one figure.
