Chapter 98's Free Menu: Which Special Classification Provisions Actually Pay Zero
Importers treat Chapter 98 of the Harmonized Tariff Schedule as a niche annex - a few oddball reliefs nobody files for. The line-level census below says otherwise. Of the 503 rate-bearing provisions in the Chapter 98 catalog, 163 (32.4%) enter the United States completely duty free, another 9 carry fractional reductions of their reference rate, and the single largest family - 204 statistical lines of USMCA-lane goods in subheading 9823 - carries no independent rate whatsoever (it is one of 290 reference-rate lines taxed per the ordinary subheading each line points back to; a further 41 units use formula rates such as repair bonds).
This is the menu most shippers never price against. Repair-and-return flows (16/16 provisions in 9813 free under bond), returned US-origin goods, exhibition material, competition trophies, film-stock exports and monofilament sampling nets all hide here - and unlike preference programs, most of these provisions are origin-blind, conditioned instead on history (was this exported?), use (will it be processed?) or documentation (is it under bond?).
The ownership model: how we counted
The raw HTS export lists 595 rows for Chapter 98, but rates attach to eight-digit provisions; ten-digit suffixes inherit their parent's rate. We therefore count rate-bearing units: an eight-digit provision owning its stated general rate, and every ten-digit child inheriting it. Structural rows without an HTS number (group headers like "Other:") own nothing and are excluded. The result is four outcome classes:
| Outcome class | Rate-bearing units | Share |
|---|---|---|
| Duty free ("Free..." in the general column) | 163 | 32.4% |
| Reference-rate lines (no independent rate; taxed per the referenced ordinary subheading) | 290 | 57.7% |
| Formula rates (value-of-repair bonds, fair-retail fractions, drawback-linked sums) | 41 | 8.2% |
| Reduced rates (reference minus a fixed fraction) | 9 | 1.8% |
Column shares are rounded independently and sum to 100.1%.
Family-by-family census
The table shows every family with at least eight rated units plus every family holding a free block; sub-eight-unit families without any free line are omitted here and covered in the worked examples. The Free column therefore sums to 127 across shown families, with the remaining 36 free units living in the small all-free families:
| Family | Coverage | Units | Free | Ref-rate | Reduced |
|---|---|---|---|---|---|
| 9801 | US goods returned after export | 53 | 45 | 0 | 0 |
| 9802 | Samples, professional equipment, tools of trade | 19 | 0 | 0 | 0 |
| 9804 | Books, libraries, household effects | 18 | 18 | 0 | 0 |
| 9808 | Engravings, etchings, photographic prints | 8 | 8 | 0 | 0 |
| 9810 | Drawings, lithographs, woodcuts, sound recordings | 20 | 20 | 0 | 0 |
| 9813 | Articles to be repaired, altered or processed | 16 | 16 | 0 | 0 |
| 9817 | Monofilament gill nets & fish-sampling gear | 31 | 19 | 1 | 0 |
| 9819 | Apparel assembled abroad from US fabric | 11 | 0 | 11 | 0 |
| 9820 | Apparel sewn abroad from US yarns/textiles | 25 | 0 | 25 | 0 |
| 9822 | Temporary admission & conditional relief | 60 | 1 | 49 | 9 |
| 9823 | Goods of Mexico or the United States (USMCA lane) | 204 | 0 | 204 | 0 |
The Free/Ref-rate/Reduced columns deliberately do not sum to the Units column: the remainder carries formula rates such as bonds or fractions of retail value, concentrated in 9801 (US goods returned) and 9802 (samples and professional equipment). Read the extremes together. Heading 9813 - articles brought in for repair, alteration or processing - is free in every one of its 16 units, but always "Free, under bond": skip the bond formalities and the relief evaporates. Family 9823, by contrast, contains 204 units yet not one free line - because it does not need one. Its lines say things like "Goods provided for in subheading 0401.40.25"; the milk-powder rate you pay is the 0401.40.25 rate, and Chapter 98 merely preserves USMCA treatment mechanics around it. Any content marketing that claims "everything in Chapter 98 is free" has not read the table above.
The nine reduced-rate lines
Nine provisions in 9822 shave a fixed fraction off the reference rate rather than zeroing it:
| Reduction shape | Lines |
|---|---|
| Reference rate minus 0.5% | 6 |
| Reference rate minus 2.0% | 3 |
Six lines grant "the duty rate provided in such subheading minus 0.5%" and three "minus 2.0%". Fractional pennies matter at scale, but the structural lesson is that Chapter 98 relief is usually binary - either fully relieved under conditions, or not relieved at all.
Worked examples worth filing for
Three provisions cover most real-world interest. First, 9813.00.20 - samples solely for taking orders - reads "Free, under bond, as prescribed in U.S. note 1 to this subchapter"; we verified the string letter-for-letter against the live USITC REST endpoint on 2026-10-22. Second, 9801.00.10 (US goods returned) grants freedom to American-made goods coming home within three years, with 45 of 53 rated units in the family free. Third, 9822's temporary admission block lets trade-show displays and racing yachts circulate under bond with duties suspended pending re-export - 49 of its 60 units are pure reference-rate lines whose cash cost is a deposit, not a tariff.
The smaller families reward niche players just as reliably. Alcoholic-beverage samples travel free under 9811 in quantities of not more than a specified per-sample volume - a gift for distilleries courting US distributors. Books, libraries and reasonable household furniture of returning families fill all 18 units of 9804 without exception. Engravings, etchings and photographic prints (9808) and drawings or sound recordings (9810) move free across every rated unit - cultural material the tariff schedule never wanted to tax. Even monofilament gill nets for fish sampling (9817) run 19/31 free. The pattern is consistent: relief follows purpose, not price point.
One caution applies across all of them: several provisions are conditional on re-export or further manufacture, so the free rate is an entry condition, not an unconditional gift - plan the paperwork before the goods move, not after the CBP form 29 notice arrives.
Filing mechanics in three steps
First, classify the transaction, not the object: Chapter 98 claims turn on the flow's history and conditions (exported before? under bond? for repair?), so build the file around documents proving those conditions - export records, bonds, processing invoices. Second, declare the Chapter 98 provision explicitly on the entry; CBP does not re-label ordinary entries into relief lanes after the fact. Third, keep the referenced-subheading arithmetic handy: for reference-rate lines the duty owed equals the ordinary rate times value, which is precisely what our calculator computes - claimants who arrive with that number pre-computed clear customs measurably faster.
Where importers leave money on the table
- Repair-and-return misclassification. Sending machinery abroad for warranty repair and importing the fix under the parts' ordinary rate instead of 9813 forfeits a free entry; the reciprocal export leg needs matching documentation.
- Ignoring the bond condition. "Free, under bond" is free because of the bond; unbolting the condition converts the entry's classification into an ordinary one, with duties calculated retroactively.
- Treating 9823 as preferential. USMCA-lane goods still owe whatever their referenced subheading owes; Chapter 98 changes the processing lane, not the arithmetic.
Audit your last year of entries against the census above: any shipment of US-origin goods returning, any repair flow, any trade-show circulation is a candidate for a free line. Our HS lookup tool resolves the ordinary heading; the tariff calculator prices what the referenced subheading would have charged; the stacked-tariffs guide shows how Chapter 98 relief interacts with Section 301-style add-ons; and our deep dives on 9801 US-goods-returned declarations and Chapter 98 special classification mechanics cover the two highest-volume provisions end to end.
Methodology and caveats
- Slice: the full Chapter 98 catalog (headings 9801-9823) from the USITC HTS REST export, snapshot vintage 2026-10-12, 595 rows.
- Ownership model: rates attach at eight digits; ten-digit statistical suffixes inherit; header rows without HTS numbers are excluded from denominators.
- "Free" by literal prefix of the effective general rate; formula/bond texts counted separately; reduction magnitudes parsed from "minus X%" strings.
- Live cross-check: USITC REST exportList responses for 9813.00.20 observed 2026-10-22 matched the snapshot exactly.
How much of Chapter 98 is actually duty free?
163 of 503 rate-bearing provisions (32.4%) enter duty free. The remainder split between reference-rate lines taxed per their ordinary subheading, formula rates such as value-of-repair bonds, and nine reduced-rate lines.
Is everything in subheading 9823 (USMCA goods) duty free?
No. All 204 rated units of 9823 are reference-rate lines: each points to an ordinary subheading (e.g. 0401.40.25) and inherits whatever duty that subheading carries. Chapter 98 changes the processing lane, not the arithmetic.
What does 'Free, under bond' mean on HTS line 9813.00.20?
The goods (order-taking samples here) enter without duty only while covered by a customs bond as prescribed in U.S. note 1 to Subchapter VIII. Breach the condition - e.g. sell the sample domestically - and duty becomes payable retroactively. We verified the rate string letter-for-letter against the live USITC endpoint on 2026-10-22.
Which Chapter 98 provision covers US goods returned?
Heading 9801. Goods of US origin returning after export enter duty free under 9801.00.10 within three years; 45 of 53 rated units in the family are free, with the remainder carrying formula-based relief.
Do Chapter 98 reliefs stack with Section 301 tariffs?
Partially. Where the referenced ordinary subheading carries a Section 301-style additional duty, Chapter 98 relief typically addresses the base duty only; exclusions and program-specific rules decide the add-on leg. Price both layers before relying on a relief claim.
