Two garments made of the same fibre can still fall under two different HS chapters, because the Harmonized System splits apparel first by whether it is knitted or woven, not by fibre alone. This lesson mainly teaches the information flow: reading a garment's own construction and turning it into the right chapter and heading. A buyer's compliance team at Northline Apparel checks this before approving a factory's own declared heading, since an approved shipment under the wrong chapter still carries real duty and customs risk once it reaches the border. A merchandiser at Delta Garments needs the same method for every new style, since a wrongly chosen chapter is not caught until a customs officer at the destination actually opens the shipment and checks the fabric against the paperwork.

Not covered here: calculating customs value (lesson 3.3), calculating duty owed (lesson 3.4), and building a complete classification and valuation sheet (lesson 3.5).
| Term | Meaning |
|---|---|
| Knit garment | A garment made from fabric formed by interlocking loops of yarn, such as Order A's own single jersey T-shirt. |
| Woven garment | A garment made from fabric formed by yarns crossing at right angles, such as Order B's own denim jeans. |
| HS chapter | The two-digit level of an HS code, the broadest grouping, that a heading sits inside. |
| HS heading | The four-digit level of an HS code, shared by every member country, that groups similar products together before a country adds its own extra digits. |
| Construction-based classification | Deciding a garment's HS chapter mainly from how its fabric is made, knitted or woven, rather than from fibre content alone. |
| Fibre content declaration | A statement of what fibres a garment is made of and in what proportion, used alongside construction to confirm a heading. |
The Harmonized System's apparel section splits into two broad chapters before anything else is considered: one chapter for knitted or crocheted garments, another for garments that are not knitted, mostly woven. This split happens before fibre content, gender, or garment type are considered at all. Order A's single jersey T-shirt is knitted, so it falls in the knitted chapter; Order B's denim jeans are woven, so they fall in the separate woven chapter, even though both are apparel made largely of cotton.
| What can differ | The shapes you will meet | Why it matters to you |
|---|---|---|
| Knit or woven construction | A knitted T-shirt like Order A's own style and a woven shirt of similar fibre content fall under two different chapters, decided by construction alone. | Checking construction first, before fibre, avoids the most common classification mistake in apparel. |
| Export or domestic movement | Order A's T-shirt and Order B's jeans both need a declared heading, since both cross a customs border to Northline Apparel. A similar T-shirt sold by Cedar & Co. inside its own country needs no heading at all, whatever its construction. | The construction rule only matters once a shipment is confirmed to be crossing a border in the first place. |
| Gender and age category | Within the same construction and fibre, a heading can differ further by whether a garment is described as men's, women's, or for a specific age group, since some national tariff schedules carry separate lines for each. | A classifier cannot stop at chapter and fibre; the garment's stated category can still change the final national digits. |
| Product family beyond basic apparel | Hosiery, knit-to-garment products, and terry or home-textile articles often sit in their own separate headings, distinct from ordinary knitted or woven garments, even when made of a similar fibre. | A person classifying a sock or a towel cannot reuse a T-shirt's or a pair of jeans' own heading unchanged. |
| Who checks the heading, and when | A merchandiser at the factory declares a heading first, when export documents are prepared. A buyer's own compliance team, like Sara's at Northline Apparel, often checks that declared heading independently before approving the shipment, since an accepted wrong heading is the buyer's own risk too. | Two independent checks, factory and buyer, catch more classification mistakes than either side checking alone. |
Sara's compliance team reviews both of Delta Garments' declared headings before either shipment is booked. Order A, a knitted cotton T-shirt, is declared under illustrative heading 6109, inside chapter 61 (knitted or crocheted garments). Order B, five-pocket jeans in woven denim, is declared under illustrative heading 6203 or 6204 depending on the stated gender category, inside chapter 62 (garments not knitted, mostly woven). Both garments are made mainly of cotton, yet they sit in two different chapters because one is knitted and the other is woven. Sara's team records both headings side by side precisely because the two orders look similar in fibre terms, and a reviewer working quickly could otherwise wrongly assume one heading should apply to both.
A single digit of difference at chapter level carries a real classification consequence: chapter 61 and chapter 62 are two separate parts of the tariff schedule, each with its own headings and, ultimately, its own duty rates.
The methodA classifier who starts from fibre content alone, reasoning "this is cotton, so it belongs with other cotton garments," can land in the wrong chapter entirely, since chapter 61 and chapter 62 both contain cotton garments, split by construction, not fibre. A common mistake is assuming a woven cotton shirt shares a heading with a knitted cotton T-shirt simply because both are cotton; they belong in different chapters, and a heading built on fibre alone, without checking construction first, is very likely wrong.
A garment's HS chapter depends mostly on how its fabric is made, knitted or woven, checked before anything else. Order A's T-shirt is knitted, so it falls in the knitted garments chapter; Order B's jeans are woven, so they fall in a separate chapter, even though both are made mainly of cotton. Fibre content and the garment's stated gender or age category narrow the heading further, but only after construction has already decided which chapter to look in. A classifier who checks fibre first and construction second risks landing in the wrong chapter altogether, since cotton garments exist in both the knitted and the woven chapters.
Sara's compliance team, reviewing shipment paperwork from Delta Garments, notices that Order A's T-shirt and Order B's jeans are declared under two different chapters, 61 and 62, despite both being made mainly of cotton. A junior team member asks whether this is a mistake that should be corrected to one shared chapter before the shipments are approved.
Here is the fact the team is comparing:
Is declaring two different chapters for two mainly-cotton garments a mistake that needs correcting? Decide before opening the answer.
No, it is not a mistake. Two facts decide this together.
First, what actually splits chapter 61 from chapter 62. The Harmonized System's split between these two chapters is construction, knitted against woven, not fibre content; cotton garments exist in both chapters.
Second, what construction each order actually uses. Order A's fabric is knitted single jersey; Order B's fabric is woven denim. Since their constructions differ, their chapters correctly differ too, even though their fibre content does not.
The junior team member's instinct that two cotton garments should match is reasonable on fibre grounds alone, but the Harmonized System classifies on construction first. Forcing both orders onto one chapter would itself be the classification error.
Framed qualitatively, correcting Order A's T-shirt or Order B's jeans onto a chapter that does not match its actual construction would not simplify anything; it would create a genuinely wrong declaration, risking rejection or a duty recalculation at the border once a customs officer checks the fabric itself. The cost of an unnecessary "fix" here is not smaller paperwork, but a real compliance failure introduced where none existed.
Leaving each order's own, correctly different chapter in place costs nothing; forcing a shared chapter risks a real customs rejection.
Open the Classification and valuation sheet workbook linked below. Its first sheet lists the classification facts one shipment at a time: fibre content, knit or woven construction, and the resulting heading. Complete one full set of rows for Order A and a separate set for Order B's jeans if you are comparing two shipments, since each shipment's own construction, not a shared fibre content, decides its own chapter.

You now know how a garment's own construction decides its HS chapter. The next lesson teaches how to calculate the customs value a duty rate is actually applied to, reading Order A's own commercial invoice line by line. Back to the course map
