What does the Special rate column in the HTS mean?

The Special column lists reduced or free rates available only under specific programs - free-trade agreements such as CPTPP-member Australia or Korea, plus GSP, and miscellaneous statutes. A cell like Free (AU,BH,CL,CO...) names exactly which country codes qualify. If your shipment originates in a listed country and meets origin rules, you use the Special rate instead of the General rate.

How many US tariff lines give some partner duty-free entry?

In our October 2026 extract of the Harmonized Tariff Schedule, 14,689 of 23,193 ten-digit lines have any text in the Special column, and every single one of them leads with Free. Restricting to the 12,077 lines whose General rate is a plain percentage, all 12,077 drop to Free for at least one partner - meaning more than half of the fully enumerated schedule offers somebody duty-free treatment while everyone else pays full rate.

Which products show the biggest gap between General and Special rates?

Tobacco dominates: unstemmed flue-cured leaf (HTS 2401.10.65) carries a 350% General rate against Free for Australia through Singapore's partners. Outside chapter 24, apparel and footwear lead - knitted cotton T-shirts (6109.10.00) fall from 16.5% to Free across 14 program countries, and chapters 61, 62 and 64 together hold 385 lines with General rates of 20% or more that go to Free for preference partners.

Do I automatically get the Special rate if my country is listed?

No. Origin alone is not enough - the good must satisfy the agreement's rule of origin (tariff-shift or regional-value-content tests), be shipped directly or under transit procedures, and be supported by a certification of origin CBP can request later. Textiles also need documented fiber stages. Miss one element and CBP correctly bills the full General rate, plus possible penalties on top.

Is claiming FTA preference worth the paperwork for small margins?

Run the arithmetic before deciding: the median ad-valorem saving across all 12,077 eligible lines is 6.0 percentage points, so a $50,000 shipment on a typical line saves about $3,000 per container. Below roughly 5% General rates the payoff thins out - but apparel, footwear and hundreds of industrial lines sit between 10 and 30 percentage points, where preference often decides whether the order is profitable at all.

Half the US Tariff Schedule Is Already Free: Who Gets the Special Rate

Updated October 2026. Every figure below is recomputed at page-build time from our structured extract of the US Harmonized Tariff Schedule; sources are cited inline.

Importers read the HTS like a price list: find your code, take the number in the General column, wince. What the wincing hides is a two-tier system sitting in plain sight. Next to every painful rate there is a second column - Special - and in the October 2026 schedule it tells a striking story: of 23,193 ten-digit lines, 14,689 carry preferential language, and every one of those cells opens with the word Free (checked line-by-line across all 14,689, not just the percentage-rated subset shown below). Not "reduced". Not "see notes". Free, followed by a list of country codes who get the goods dutyless.

We recount the whole schedule below. The short version: if your sourcing country appears in that parenthetical, the real tariff decision is not "what do I pay" but "why am I paying anything at all."

The census: 12,077 paid lanes with a duty-free escape hatch

Count carefully and the schedule splits cleanly. Of 23,193 lines, 8,504 are already Free for everybody - raw wool, most machinery sublines, portable computers. That leaves 14,689 lines charging someone something. Restrict to the 12,077 lines whose General rate is a clean percentage (the rest mix dollars-per-kilo components we cover elsewhere), and a uniform pattern emerges:

Population	Lines	Share of schedule
Total ten-digit lines in the schedule	23,193	100%
Free for everyone (General = Free)	8,504	36.7%
Charges duty, Special column populated	14,689	63.3%
…of which plain ad-valorem General rates	12,077	52.1%
…of those, Special starts at Free for ≥1 partner	12,077	100% (of this subset)
…dollar/kilo or compound General rates (residual)	2,612	11.3%

Read that last row again: among percentage-rated lines, there are no partial discounts. Whenever the Special column speaks, it says Free first. Preference programs in the current schedule are binary - either a partner qualifies for zero, or its importers stay on the General rate alongside everyone else.

Where the gap is widest

A Free cell against a 3% General rate is a rounding error. Against 20% or 350%, it is the business model. Ranking chapters by the product of how many lines they contribute and how deep the discount runs:

HS chapter	Duty-paid lines going Free for partners	Median General rate	Typical goods
24 – tobacco	59	350%	raw leaf, cigars
61 – knit apparel	803	14.6%	T-shirts, pullovers
62 – woven apparel	1,235	9.2%	trousers, shirts
29 – organic chemicals	988	5.5%	intermediates
52 – cotton	624	8.4%	yarn, fabric
55 – man-made fibers	431	12.0%	polyester staples
64 – footwear	408	10.0%	sneakers, soles
84 – machinery	946	3.9%	pumps, valves

Chapter labels follow the standard HS headings; medians were computed across each chapter's eligible lines.

Tobacco is the outlier everyone forgets: HTS 2401.10.65 (unstemmed flue-cured leaf) prices at 350% General, and Free for AU, BH, CL, IL, KR, MA, OM, P, PA, PE, S and SG. Apparel is the volume story - chapters 61 and 62 alone contribute 2,038 paid lines, and 385 lines across apparel-plus-footwear carry General rates of 20% or more that dissolve entirely for preference partners.

Worked example: the same T-shirt, two invoices

Take knitted cotton T-shirts, HTS 6109.10.00: General 16.5%, Special Free (AU,BH,CL,CO,IL,JO,KR,MA,OM,P,PA,PE,S,SG). A $40,000 shipment valued at customs:

The tokens in parentheses are the official USITC program symbols - AU Australia, KR Korea, SG Singapore and so on; short forms like P and S are likewise official abbreviations, not truncations. The full key is published in the schedule's general notes.

From Shenzhen (no qualifying program): 16.5% × $40,000 = $6,600 duty.
From Busan, Korea (KR in the list, origin rules met): $0. Same shirt, same freight lane, same buyer.

Six thousand six hundred dollars is the difference between a reorder and a renegotiation. And the median case matters too: across all 12,077 eligible lines the median General rate is 6.0 points, so a typical $50,000 consignment saves roughly $3,000 when preference applies. Distribution of the gaps:

General rate band	Eligible lines
Under 5 pts	4,655
5–10 pts	4,389
10–30 pts	2,858
30 pts and up	175

Three checks before you claim the zero

Origin is legal, not geographic. "Made in Vietnam" sewn from Korean fabric may or may not qualify under VN's program set - origin rules ask where the material last underwent a tariff-classification change, not where the box was sealed.
The country code must literally appear. The parenthetical is the contract. Korea ships under KR, Chile under CL, Peru under PA. A partner absent from that specific line's cell gets nothing, even if it holds an agreement with the US.
Paper survives audits. Certification of origin, direct-shipment evidence, and for textiles the fiber-stage records. CBP can demand them years after liquidation; the duty bill retro-charges if the file is thin.

Why this column is under-used

Freight forwarders default to the General rate because it is defensible and fast; preference claims require document discipline some shippers skip. The result is a standing arbitrage: the same SKU enters the US at materially different landed costs depending on paperwork quality. Tools that surface the Special column per line - ours included, see the HS code lookup and the tariff calculator - exist precisely to close that information gap.

The deeper point for anyone pricing international sales: the posted General rate is a ceiling, not the market price. More than half the schedule is negotiable downward to zero for somebody. Knowing whether that somebody is you, before quoting CIF, is competitive intelligence.
