Classifying base metal articles: a worked walkthrough of HTSUS Chapters 73, 82, and 83
Base metal goods split across three chapters by what the item does, not just what it is made of: Chapter 73 holds structural and general iron-or-steel products, Chapter 82 holds tools and cutlery of any base metal, and Chapter 83 holds miscellaneous base metal hardware like locks and fittings. A steel garden rake is a named tool (heading 8201), so it is not classified in Chapter 73's residual 'other articles of iron or steel' heading even though it is made of steel.
Chapters 73, 82, and 83 all hold base metal goods, and candidates who classify by material alone (it is steel, so it must be Chapter 73) miss the real sorting rule: these three chapters split by what the article is used for, and a specifically named heading in Chapter 82 or 83 beats a general or residual heading in Chapter 73 almost every time. This walkthrough works four real classification scenarios.
Scenario 1: a steel garden rake
A steel rake, made entirely of iron or steel, looks at first glance like it belongs in Chapter 73, “articles of iron or steel.” Chapter 73’s last heading, 7326, is written as a residual catch-all: “other articles of iron or steel,” meaning items of iron or steel not more specifically described elsewhere in the tariff. That “not more specifically described elsewhere” qualifier is the whole answer here.
Heading 8201 in Chapter 82 covers “handtools of the following kinds and base metal parts thereof: spades, shovels, mattocks, picks, hoes, forks and rakes” among other named agricultural handtools. A rake is named in the heading text itself. Under GRI 1, the named, specific heading (8201) controls, and the rake never reaches 7326, because 7326 by its own design only catches iron-or-steel articles that no more specific heading names. This is the single most common Chapter 73 exam trap: assuming “it is steel” routes an item to Chapter 73, when Chapter 82’s function-based headings for tools apply regardless of what base metal the tool is made from.
Scenario 2: brass door hinges
A hardware importer brings in brass hinges designed for interior doors. Chapter 83 exists for exactly this kind of hardware: heading 8302 covers “base metal mountings, fittings and similar articles suitable for furniture, doors, staircases, windows, blinds, coachwork, saddlery, trunks, chests, caskets or the like.” The heading text names “doors” directly, and it applies to “base metal,” not just iron or steel, which is why a brass hinge (brass is a copper-zinc alloy, not iron or steel) fits 8302 without needing to reach for a residual Chapter 74 (copper) heading. GRI 1 resolves this on heading text alone: a fitting “suitable for… doors” is named, so it is classified there rather than by its base-metal material chapter.
Scenario 3: a stainless steel mixing bowl versus a stainless steel serving spoon
A kitchenware importer brings in two stainless steel items in the same shipment: a mixing bowl and a serving spoon. Both are the same material. They classify in different chapters.
The serving spoon is named directly: heading 8215 covers “spoons, forks, ladles, skimmers, cake-servers, fish-knives, butter-knives, sugar tongs and similar kitchen or tableware; and base metal parts thereof.” That heading sits in Chapter 82 alongside handtools and cutlery, because spoons and forks are grouped with cutlery by function, not with general household articles.
The mixing bowl is not a named utensil in that list; it falls to heading 7323, “table, kitchen or other household articles and parts thereof, of iron or steel,” a Chapter 73 heading for iron-or-steel household goods that are not cutlery. So two stainless steel kitchen items from the same shipment split across two chapters (82 and 73) because one is cutlery-type tableware with its own named heading and the other is a general household article, and the exam expects a candidate to catch that split rather than classify the whole shipment as “kitchenware” under one heading.
Scenario 4: a combination tool set for retail sale
A retailer imports a boxed set containing pliers, a wrench, and a screwdriver, packaged together for sale as a single consumer product. Chapter 82 has a heading written specifically for this packaging pattern: 8206, “tools of two or more of headings 8202 to 8205, put up in sets for retail sale.” When individual tools from those specific headings are boxed together as a retail set, the set itself has its own heading rather than being split apart and classified tool by tool, or reasoned through GRI 3(b)‘s general essential-character test for sets. Heading 8206 is a case where the nomenclature pre-solved the “set” question for one product category by writing a dedicated heading; compare this to sets that are not covered by a dedicated heading, which do require the general GRI 3(b) analysis covered in the composite goods and retail sets walkthrough.
Quick reference: all four scenarios
| Item | Material | Heading | Why |
|---|---|---|---|
| Garden rake | Steel | 8201 (Chapter 82) | Named agricultural handtool; beats the Chapter 73 residual heading |
| Door hinge | Brass | 8302 (Chapter 83) | “Suitable for… doors” names the function; base metal, not iron-or-steel-only |
| Mixing bowl | Stainless steel | 7323 (Chapter 73) | General household article, not a named cutlery item |
| Serving spoon | Stainless steel | 8215 (Chapter 82) | Named cutlery/tableware heading, same shipment as the bowl above |
| Tool set (pliers, wrench, screwdriver) | Mixed base metal | 8206 (Chapter 82) | Dedicated “set” heading pre-solves the packaging question |
The pattern across all four scenarios
In every scenario, the deciding question was never “what metal is this?” alone. It was “does a heading in Chapter 82 or 83 name this specific article or function?” first, and only when no such heading exists does an iron-or-steel item fall into Chapter 73, and even then usually into one of Chapter 73’s many function-specific headings (springs at 7320, chain at 7315, wire rope at 7312, nails and screws at 7317 and 7318) rather than the residual 7326. Reading the full heading text before assuming a material-based chapter is the discipline this section of the exam tests.
