What an HS code actually does
The Harmonized System is the international nomenclature customs administrations use to classify traded goods, organized as six-digit headings that national tariffs extend with further digits for their own duty schedules. Classification is not a formality. It decides the duty rate an entry pays, the treatment the shipment receives at the border and the statistics the trade is counted in. A wrong code is therefore not a typo but a liability: duty paid at the wrong rate is duty that has to be corrected retrospectively, and inconsistent codes across shipments invite the kind of review every launch calendar can do without.
The vocabulary helps to keep straight. The six-digit heading is international; the longer line beneath it is national; and the duty rate hangs off the national line, not the heading. Buyers who say HS code often mean the whole stack - heading, national line, rate - and the stack is exactly what the customs broker assembles per destination.
Two habits keep the stack stable. First, classification is settled per construction and per destination before the first booking, not negotiated per shipment; a code that changes between orders of the same fabric is a symptom worth investigating. Second, the facts behind the code are written once, in the program file, and reused: the same bill of materials that feeds the labels and the certificates feeds the broker, which is why classification is cheap for programs whose documents are already in order and annoying for programs whose documents are assembled per shipment.
The reference headings for intimates
Two reference areas cover most of the category. Bras and corsetry sit under heading 6212, which covers them across constructions, and knitted underwear and nightwear sit in the 6108-6109 range. The table arranges the references; the exact code per destination - including the further digits each tariff adds - is a customs-broker question.
| Garment family | Reference heading | Note |
|---|---|---|
| Bras and corsetry | 6212 | Covers bras across constructions; the exact national line is confirmed with the broker |
| Knitted panties | 6108 range | Knitted constructions; chapter 61 is the knitted chapter |
| Knitted nightwear and sleep-adjacent styles | 6109 range | Loungewear styling can move between references; the broker reads the construction |
| Woven constructions | Chapter 62 references | Construction drives the chapter; woven pieces are classified outside the knitted chapter |
Read the middle column as starting points, not answers. Tariff schedules differ in how far they extend the headings, and duty treatment differs by destination; the six digits are the shared language, and the line beneath them is local.
Why construction matters more than style
Two garments that look alike can classify differently because the tariff reads construction before it reads fashion. Knitted and woven goods sit in different chapters - 61 and 62 - and the difference is a fabric fact, which is why the desk keeps fabric construction in writing in every program file. Sets raise their own question: how a bra and panty set put up in retail packaging classifies, as one line or two, is a broker question that depends on the packaging and presentation, so sets are flagged early. Trims, lace content and elastane percentages rarely move the heading, but they support the facts behind it, and the same written bill of materials serves both the label and the classification.
Where the broker fits
Classification for a destination is the customs broker's work, done on facts the supply chain provides. The division is clean: the plant and the desk supply the construction facts - fabric type, knit or woven, garment family, packaging format - in writing; the broker reads them against the destination tariff and returns the code; the program records the code with the entry papers. What the desk does not do is classify, and what the plant does not do is guess. When a broker asks for a sample or a fabric detail, the answer travels fast, because the file already holds it. The pattern is the same one that governs the rest of the compliance file: facts in writing, specialists on the interpretation, and a record that lets the next shipment start from the file instead of from memory.
What mistakes cost
Misclassification surfaces in three ways, all slower than getting it right. Duty is paid at the wrong rate and has to be corrected, sometimes across shipments. Entries are held while the code is clarified, and the delay lands on a launch calendar. And downstream reviewers - retail chains, marketplaces - ask for classification in onboarding and find inconsistencies that were never probed at the border. Consistency is the cheap insurance: the same construction, the same facts, the same code at every destination the program ships to, with origin statements that agree with the entry, as the note on fiber labeling describes for the label side. None of the three shows up as an error message; each shows up as time.
Setting codes for a program
- Write the construction facts into the program file: fabric type, knit or woven, garment family, packaging format.
- Send the facts to the customs broker for each destination before the first booking.
- Record the returned codes with the entry papers, per destination.
- Flag sets and multi-piece retail packs early - presentation affects how they are read.
- Revisit the codes whenever construction changes: a woven panel added to a knit program is a new fact.
- Keep origin on the label, the invoice and the entry telling one story.
What the desk does
The desk coordinates the fact flow: construction details from partner plants in writing, packaging and presentation documented for sets, entry papers assembled before sailing. Classification stays with the customs broker, and duty questions stay with the broker too. Reference ranges for samples, bulk and freight sit on MOQ and lead time and on the logistics and shipping page; a program brief that lists destinations and constructions lets the desk stage the papers in the right order, and the quote form carries that list. For the two largest destinations, the notes on importing into the US and importing into the EU show the codes inside the full entry sequence.
