The Textile Tariff Ladder: From Cotton Fiber to Finished Apparel, Computed Line by Line

Every figure below was recomputed directly from the full US Harmonized Tariff Schedule extract (23,193 ten-digit statistical lines, USITC REST vintage 2026-10-09T17:43Z). Nothing is quoted from secondary sources.

If you import textiles, you already know the US tariff schedule treats your product differently from almost everything else. What most sourcing guides won't tell you is how systematically it does so: the schedule is built as a ladder, and the rungs rise with every step of processing. We computed the entire staircase from the raw schedule. Here is what it looks like when you stop quoting "typical ranges" and start counting lines.

The ladder in one table

Section XI of the Harmonized Tariff Schedule (chapters 50–63) contains 4,974 ten-digit lines. Of these, 4,141 carry an ad-valorem general rate, 141 are compound (cents-per-unit plus a percentage), 30 are pure specific duties, 400 are duty-free, and the remaining 262 express their rate as prose. On those 4,141 ad-valorem lines the median general rate is 9.7% and the mean 11.2% — against a whole-schedule median of just 6.0% across 12,110 ad-valorem lines. Textiles are, line for line, one of the most heavily protected industrial blocks in the US schedule.

The pattern repeats whether you follow cotton, wool or synthetics: the stairs are uneven by design. Fabric rungs barely rise (yarn to woven fabric adds four tenths of a point at the median), but crossing into finished knitwear jumps the median from 10.0% to 16.5%, and inside a single garment heading the fiber choice can add another 15.5 points. This is textbook tariff escalation — but seeing it as measured stairs rather than an assertion changes how you plan landed cost.

Stage 1: raw fiber enters by the cent, not the percent

Unspun cotton doesn't even play the ad-valorem game. All twelve lines of heading 5201 are priced in cents per kilogram: three variants are outright Free (harsh or rough cotton under 1 1/8 inches, plus two program-specific lines), and the remaining nine range from 1.5¢/kg for certain note-designated staple lengths to 31.4¢/kg for the "Other" catch-all lines. At a benchmark cotton price around $1.60/kg, even the top 31.4¢/kg line works out to roughly a 20% equivalent — but the specific structure means the burden falls predictably per tonne, not per value, which matters enormously when commodity prices swing.

Wool shows the transition form: carded or combed wool in fragments carries compound lines like 6.5¢/kg + 5.3% (5101.21.70.00, 5101.29.70.00, 5101.30.70.00) — a specific floor bolted onto an ad-valorem top-up.

Stage 2: yarn and fabric clear a 9–10% plateau

Spin the fiber into yarn and the schedule switches to percentages. All 62 lines of cotton yarn (heading 5205) are ad-valorem, with a 9.3% median, a 3.7% floor and a 12.0% cap. Weave or knit that yarn into fabric and the plateau barely moves: woven cotton fabrics under 5208 have a 9.7% median across their 177 ad-valorem lines (peak 14.7%), and knit fabric 6006 lands at a 10.0% median with a maximum of exactly 10.0%. For comparison, our product-category census shows the all-commodity distribution is dominated by much cheaper rates; fabric sits deliberately above it.

This plateau is the cheap part of the ladder. A converter buying Chinese or Indian fabric faces single-digit-to-low-double-digit duties that are almost boring by apparel standards. Which is precisely the point: the escalation structure exists to pull conversion activity — cutting, sewing, finishing — onshore.

Stage 3: finished goods climb to a 32% ceiling

Cross into chapters 60–63 and the stairs steepen. Finished goods span 2,417 ad-valorem lines with a 10.0% median — modestly above intermediates — but the tail is far heavier:

• Knit tops, heading 6109 (T-shirts, singlets, tank tops): a 16.5% median across all 40 lines, ranging from 2.6% to 32.0%.
• Woven women's apparel, heading 6204 (suits, dresses, skirts): a 13.6% median across 276 ad-valorem lines, floor 1.0%, peak 28.6%.
• All knitwear, heading 6110 (sweaters, pullovers): a 6.3% median across 135 lines — proof that within finished goods, individual headings still vary widely.

The ceiling itself is a man-made-fiber story. Exactly 42 lines in section XI sit at the 32% maximum, spread over seven eight-digit families — and every one of them is a man-made-fiber knit garment: shirts (6105.20.20), blouses (6106.20.20), man-made-fiber T-shirts (6109.90.10, 13 lines), sweaters (6110.30.30, 15 lines), baby blouses (6111.30.20), baby T-shirts (6111.30.30) and bodysuits (6114.30.20). The material cliff operates inside a single heading: cotton T-shirts enter under 6109.10.00 at 16.5% while the otherwise-identical man-made-fiber version 6109.90.10 pays 32%. Fiber choice alone nearly doubles the statutory rate.

Taken together, 2,045 textile ad-valorem lines (49.4%) run at 10% or more, 786 (19.0%) at 15% or more, and 294 (7.1%) reach the 25% bracket that our full-schedule census identified as the high-tail threshold.

Column 2 turns the ladder into a wall

For exporters shipping from countries without normal-trade-relations status, the ladder becomes a wall. Every line in the T-shirt heading 6109 carries a Column 2 rate of 55.5% or 90% — against general rates of 16.5–32%. Knit fabric 6006.31.00 goes from a 10% general rate to 113.5% in Column 2. Our dedicated guide covers the full Column 2 mechanics; the takeaway here is that textile escalation compounds, it doesn't merely add.

How FTA partners skip the ladder entirely

The escape hatch is written directly into the Special column. Across chapters 61–62 (the two big apparel chapters, 2,456 statistical lines counting every rate form), 2,409 lines carry a Special designation beginning with Free: 1,541 of them name exactly the 14-partner preferential string (AU, BH, CL, CO, IL, JO, KR, MA, OM, P, PA, PE, S, SG), and the remaining 868 layer legacy preference symbols such as E or A on top of the same partner list. A cotton T-shirt that statutorily owes 16.5% enters duty-free from any eligible partner with compliant origin documentation — a 16.5-point spread on identical merchandise, decided purely by paperwork.

That paperwork is the hard part. Rules of origin for apparel (yarn-forward, fabric-forward requirements) are among the strictest in the schedule, and misclassification between the 16.5% and 32% brackets is a classic audit finding. Check your lines against our FTA eligibility checker, then verify the exact ten-digit line in the tariff calculator before you book freight.

Planning around the ladder: three practical moves

1. Price the fiber decision, not just the factory. If your product can be made of cotton instead of man-made fiber (or vice versa) without changing its market appeal, the 6109 example shows a 15.5-point statutory swing on the same garment shape. Run both ten-digit lines through the calculator before sampling.
2. Remember that escalation compounds with Chapter 99 add-ons. The ladder rates are base-schedule figures; Section 301 or reciprocal-provision layers stack on top of them, as our stacked-tariffs guide shows — a 16.5% base can easily become a mid-40s effective rate.
3. Audit your classification against dispute frequency. Fabric-content judgments drive both the rate and the preference claim. Where CBP ruling history shows heavy litigation (our rankings put several textile prefixes at the top), assume your first instinct will be contested and document fiber composition accordingly — then cross-check the whole family in our HTS browser.

The bottom line

Textile protection in the US schedule is not an accident of history; it is a designed staircase — fiber by the cent, intermediate fabric at a 9–10% plateau, finished garment headings at 13.6–16.5% medians with a 32% man-made-fiber ceiling, and a 90% Column 2 wall behind it all. Every number in this article is recomputable from the live schedule, and the staircase hasn't moved in the October 9, 2026 extract. If your landed-cost model still uses "apparel runs about 10–20%", you're paying for precision you could have for free.

Frequently asked questions

What is the average US tariff on textiles and apparel?

Across the 4,141 ad-valorem lines of textile section XI (chapters 50-63), the median general rate is 9.7% and the mean is 11.2% - well above the whole-schedule median of 6.0% across 12,110 ad-valorem lines. Intermediate products (chapters 50-59) have a 9.1% median over 1,724 lines, while finished goods (chapters 60-63) sit at a 10.0% median over 2,417 ad-valorem lines.

Why do finished garments face higher tariffs than fabric?

The tariff schedule is built like a tax ladder that rises with each processing step, which keeps protection concentrated on the labor-intensive assembly stage where competing industries want it. In practice: cotton yarn (heading 5205) has a 9.3% median, woven cotton fabric (heading 5208) a 9.7% median, but knit T-shirts and tank tops (heading 6109) carry a 16.5% median and woven women's suits and skirts (heading 6204) a 13.6% median.

What is the highest tariff rate on clothing in the US schedule?

Exactly 42 ten-digit lines in textile section XI carry the 32% ceiling, spread over seven eight-digit families - and every one of them is a man-made-fiber knit garment: shirts (6105.20.20), blouses (6106.20.20), T-shirts (6109.90.10 with 13 lines), sweaters (6110.30.30 with 15 lines), baby blouses (6111.30.20), baby T-shirts (6111.30.30) and bodysuits (6114.30.20). Within the same T-shirt heading, switching from cotton (6109.10.00 at 16.5%) to man-made fibers nearly doubles the statutory rate.

Do FTA partner countries pay zero duty on apparel?

On paper the Special column already waives most of the ladder: 2,409 of the 2,456 statistical lines in chapters 61-62 carry a Special designation starting with Free. 1,541 of them name exactly the 14-partner US free-trade string (AU, BH, CL, CO, IL, JO, KR, MA, OM, P, PA, PE, S, SG); the remaining 868 add legacy preference symbols such as E or A on top of the same partner list. Eligibility still depends on origin rules and documentation - use our FTA eligibility check before assuming your shipment qualifies.

What happens if my country has no normal trade relations status?

Column 2 rates apply, and for textiles they are punitive: every line in the T-shirt heading 6109 carries a Column 2 rate of either 55.5% or 90% against a 16.5%-32% general rate, and knit fabric 6006.31.00 jumps from 10% to 113.5%. See our Column 2 guide for the full non-NTR picture.
