When the Schedule Names No Number: Decoding 550 Prose-Only Rate Lines in the US HTS
Census computed from ExportSonar's machine-readable copy of the Harmonized Tariff Schedule (23,193 lines, USITC export generated 2026-10-09); every figure in this guide is reproducible from that dataset.
Most tariff lookups end with a number. But run enough queries and you hit a wall the lookup tools rarely mention: hundreds of HTS lines have no number in the duty column at all. Instead they carry sentences — "The rate applicable to the natural juice in heading 2009", "1.7¢/kg on lead content", "The rate applicable to each garment in the ensemble if separately entered." We counted 550 such lines in the current schedule of 23,193 — 2.4% of the schedule, concentrated exactly where casual importers stumble: beverages, watches, tool sets, embroidery and sugar. This guide sorts all 550 into six resolution patterns and shows how to compute each one.
Six patterns cover every sentence in the schedule
| How the cell talks | Lines | Worked example | Resolution |
|---|---|---|---|
| Ensemble rule | 252 | "rate applicable to each garment in the ensemble if separately entered" | Classify each garment alone; sum the duties |
| Component-based | 233 | "1.7¢/kg on lead content" | Weigh or assay the named component, apply the rate to it |
| Cross-reference | 27 | "rate applicable to the natural juice in heading 2009" | Look up the pointed-to line and borrow its rate |
| Conditional formula | 18 | "3.6606¢/kg less 0.020668¢ for each degree under 100" | Measure sugar polarity, plug into the formula |
| Note-pointer | 10 | "See additional U.S. note 3" | Read the chapter endnote, which carries the terms |
| Remaining prose | 10 | "rate of duty applicable to that article in the set subject to the highest rate" | Rate-set logic: apply the highest member rate |

Cross-references: the rate lives one heading away
The four juice-drink lines (2106.90.52.00, 2106.90.54.00, 2202.99.36.00, 2202.99.37.00) all defer to heading 2009. That target heading contains 82 rate lines publishing 15 distinct rates once spacing variants are normalized — from Free (grape juice, 2009.79) up to 7.9¢/liter for most single citrus juices. Which one applies depends on what your blend is made of, which is precisely what the blend importer usually cannot change after formulation. Two watch-movement lines (9110.11, 9110.90.20) defer to "the complete, assembled movement", twenty lines across measuring instruments (9017.90) and trims (9005.90, 9620.00) defer to the article they belong to, and one line — 9608.50.00.00, fountain pen nibs — names its rate only "in the absence of this subheading", a legislative artifact worth reading slowly.
Component duties: the tax hides inside the product
The largest bucket after apparel is 233 component-based lines. Canned olives pay 3.7–8.6¢/kg on drained weight; copper ores pay 1.7¢/kg on lead content; tungsten concentrates pay 37.5¢/kg on the tungsten itself. Firearms split the rate between the rifle (3.1%) and its telescopic sight (13%). Watches dominate the pattern — 85 of the 233 sit in chapter 91, splitting duty among case, strap and battery:
| Product family | Duty text | What you must measure |
|---|---|---|
| Canned olives (0711.20) | 3.7–8.6¢/kg on drained weight | Drained weight of the pack |
| Copper ores (2603) | 1.7¢/kg on lead content | Assay of contained lead |
| Tungsten / molybdenum (26xx) | 37.5¢/kg W / 17.8¢/kg Mo | Contained metal weight |
| Rifles with scopes (9301/9302) | 3.1% on rifle value + 13% on scope value | Value split across components |
| Wristwatches (9102/9110...) | e.g. 44¢ each + 6% on the case + 14% on the strap + 5.3% on the battery | Count, and value of each part |
The economics bite hardest when the taxed component is cheap relative to the product: a cents-per-kilogram charge on a light-but-valuable assembly is close to free, while the same charge on a heavy-cheap ore shipment dominates the landed cost. Our specific & compound duty arithmetic guide covers the plain mixed-rate case; the component bucket adds a weighing step that no percentage-only calculator performs.
Sets and ensembles: 252 apparel lines and one honest shortcut
Chapter 61 (knit) contributes 136 lines and chapter 62 (woven) another 116, all repeating one sentence: "The rate applicable to each garment in the ensemble if separately entered." For a retailer importing a knit top with matching skirt, the computation is: classify each garment alone, compute each duty, sum. Five further lines in the tool and cutlery chapters (8205.90.60.00, 8206.00.00.00, 8211.10.00.00, 8215.10.00.00, 8215.20.00.00) encode the same idea from the other side — the whole set takes the rate of the highest-rated member. And a typographical fossil hides in plain sight: 12 apparel lines repeat the typesetting error "in the in the ensemble", proof that the sentence is retyped by hand somewhere upstream rather than generated.
The sugar slide rule
Eighteen sugar lines (1701.12/13/14/91/99) carry a genuine formula. Raw cane sugar lists 3.6606¢/kg less 0.020668¢ for each degree under 100 degrees, but not less than 3.143854¢/kg; refined lines start at 1.4606¢ with a floor of 0.943854¢. Both bands span an identical 0.516746¢, so the discount runs out — the floor binds — below about 25 degrees, meaning severely degraded sugar ships at the floor rate no matter what. Worked example: at 96 degrees, the raw rate is 3.6606 − (4 × 0.020668) = 3.577928¢/kg.
The zombie corner: notes, jewels and pins
Ten embroidery lines (all under 5810) do not even gesture at a rate — they say "See additional U.S. note 1" through note 5, pushing the reader to the chapter endnotes. Two grandfathered watch formulas count jewels and plates in a single breath ("4.3% + 1.7¢/jewel + 0.2¢ for each other piece or part, but if consisting in part of a plate or a set of plates…"), and three pin lines charge fractions of a cent per line per gross. One operational consequence matters: every non-standard row carries its sentence into the special-rate and Column 2 columns too — all 550 of them — so preferential claims and non-NTR pricing inherit the same decoding problem. For how expired preference programs interact with such cells, see our special-designation decoder; for how orders stack on top of any of these rates, see the AD/CVD lookup guide; and for the overall rate landscape by sector, the category-level tariff map. Or run the resolved number straight through the duty calculator.
Frequently asked questions
- How many HTS lines have no numeric duty rate?
- We counted 550 of the 23,193 lines in the October 2026 Harmonized Tariff Schedule extract — 2.4 percent — whose general duty column contains an instruction instead of a number. They fall into six patterns: 252 ensemble rules, 233 component-based duties, 27 cross-references, 18 conditional formulas, 10 note-pointers, and 10 residual prose lines.
- What does 'The rate applicable to the natural juice in heading 2009' mean?
- It is a cross-reference: the blended beverage you are classifying takes whatever rate the corresponding single-juice line carries in heading 2009. That heading spans 82 rate lines and 15 distinct published rates, from Free (grape juice) up to 7.9 cents per liter (most single citrus juices), so identifying which 2009 line your blend matches is the whole computation.
- How does a component-based duty work?
- The duty attaches to one named constituent rather than the whole article: 1.7 cents per kilogram on the lead content of copper ores, 37.5 cents per kilogram on tungsten content, 8.6 cents per kilogram on the drained weight of canned olives, or separate percentages on a rifle versus its telescopic sight. You must weigh or assay the named component first, then apply the cents-per-kilogram figure to that quantity.
- How is the sugar duty formula calculated?
- Raw and refined cane sugar pay 3.6606 or 1.4606 cents per kilogram, reduced by 0.020668 cents for each degree under 100 degrees of polariscope reading, with floors of 3.143854 and 0.943854 cents respectively. At 96 degrees the raw-sugar rate is 3.6606 minus 4 times 0.020668, i.e. 3.577928 cents per kilogram; below about 25 degrees the floor binds and the price stops falling.
- Do the special and Column 2 columns also use sentences?
- Yes. Every one of the 550 non-standard rows repeats its instruction in the special-rate column and again in the Column 2 column of our machine-readable extract, so the same decoding problem affects preferential and non-NTR-country treatment, not just the general rate.
- Why do ten HTS lines say 'See additional U.S. note'?
- All ten are embroidered textile lines under subheadings 5810.91, 5810.92 and 5810.99, and each points to additional U.S. notes 1 through 5 of chapter 58, which spell out the actual duty treatment for specific embroidery categories. The rate therefore lives outside the tariff table entirely, in the chapter endnotes.
