Trumpets, trombones, and tubas caught in Section 232: brass-wind musical instruments proposed for inclusion
Federal Register 2026-15961 proposes adding brass-wind musical instruments (HS 9205.10) plus parts and accessories to the Section 232 derivative scope. Public comments close Aug 27 2026. The rationale: brass is a copper-zinc alloy and copper is now covered under Section 232. School music programs, professional musicians, and retail chains face a 50 percent general (25 percent UK) stack on top of the base MFN rate once effective. Here is the HS deep dive, the buyer map, the projected stack math, and comment framing angles for music-industry importers.

Open calculatorBrass-wind instruments caught in Section 232
Federal Register 2026-15961 (Aug 6 2026) proposes adding brass-wind musical instruments (HS 9205.10) plus parts and accessories to the Section 232 derivative scope. Public comments close 11:59 PM ET on August 27. The unusual case: musical instruments landing in a metals derivative rule.
The rationale is copper. Brass is a copper-zinc alloy and copper is now covered under Section 232 (Proclamation 11021, June 2026). BIS is treating brass-wind instruments as a copper derivative for the same reason it treats insulated copper conductors and copper pipe fittings as derivatives: the finished good contains a material share of covered metal that would otherwise escape the 232 regime at the finished-good HTSUS level.
School music programs, professional musicians, orchestras, retail chains, and military bands are all affected. Here is the HS deep dive, the buyer map, projected stack math, and comment framing angles.
HS 9205: the classification structure
Chapter 92 of the HTSUS covers musical instruments and parts. HS 9205 is the specific heading for wind musical instruments, split at the 6-digit level between 9205.10 (brass-wind) and 9205.90 (other wind, including woodwinds and accordions).
9205.10 brass-wind instruments. US 8-digit and 10-digit statistical breakouts differentiate by instrument type: 9205.10.0020 trumpets, cornets, and flugelhorns; 9205.10.0040 trombones; 9205.10.0060 French horns; 9205.10.0080 tubas, sousaphones, and other low brass. Current MFN column 1 rate: 2.9 percent ad valorem across all subheadings.
9205.90 other wind instruments and parts. Includes woodwinds (clarinets, saxophones, flutes) under separate breakouts, plus 9205.90.20 for parts and accessories of wind instruments generally. The Fed Reg 2026-15961 proposal targets 9205.90 parts where the parts contain a material share of copper alloy content (valve pistons, valve casings, tuning slides, mouthpieces). Woodwind parts made of wood, plastic, or non-brass metals are not in scope.
The buyer map
School music programs. K-12 school districts and higher education music departments buy entry-level and intermediate instruments in bulk through educational distributors (West Music, Music and Arts, Woodwind and Brasswind education sales, Interstate Music). Typical unit price 400 to 1,500 USD for entry-level trumpets and trombones, 1,500 to 4,000 USD for intermediate. Contract cycles run 3 to 5 years with a school district. Most instrument volume in this tier is imported from Taiwan (Jupiter, Mendini) or China (Blessing, Wisemann, Cecilio).
Professional musicians and orchestras. Premium instruments priced 3,000 to 20,000 USD per unit from Bach (Elkhart Indiana, Conn-Selmer), Yamaha (Japan), Schilke (Melrose Park Illinois, some US production), Kanstul (US), Getzen (US), Adams (Netherlands), Bach Stradivarius (US professional line), Conn 8D French horn (US), Miraphone tuba (Germany). Import share concentrated in Japanese, German, and Dutch origin.
Retail chains and specialty music stores. Sam Ash, Guitar Center, Music and Arts, Woodwind and Brasswind, and regional specialty stores stock inventory across all price tiers. Retail markup pressure means the 232 stack cannot be fully absorbed at the wholesale layer.
Military bands and municipal ensembles. US Army Band, Marine Band, Air Force Band, Navy Band, plus municipal police and fire ceremonial units buy through DLA or GSA contracts. Volume is modest but visibility on the political comment framing angle is high.
Current versus projected stack
Baseline: 100,000 USD CIF shipment of Chinese-origin trumpets at HS 9205.10.0020 sold into the education market.
Current stack (Aug 18 2026 pre-inclusion).
MFN column 1 at 2.9 percent: 2,900 USD.
Section 232: 0 USD (chapter 92 not currently in derivative annex).
Section 301 List 4A at 7.5 percent for China origin: 7,500 USD.
Section 301 forced-labor tier A at 12.5 percent for China origin (post-July-24): 12,500 USD.
MPF cap: 634.62 USD.
HMF: 125 USD.
Current total duty: 23,660 USD (24 percent effective rate on CIF).
Post-inclusion stack (Aug 27 comment close, proclamation issued, CBP CSMS effective).
Two scenarios depending on whether the importer files a producer affidavit identifying copper content share.
Scenario A: affidavit filed, copper content share identified.
For yellow brass at 63 percent copper by weight (typical for trumpet body tubing and valve assemblies), the copper content share by value is roughly 65 to 70 percent when accounting for the copper premium over zinc.
Section 232 at 50 percent on copper content share (assume 68 percent copper by value): 100,000 x 0.68 x 0.50 = 34,000 USD.
Total post-inclusion duty: MFN 2,900 + S232 34,000 + S301 List 4A 7,500 + S301 forced-labor 12,500 + MPF cap 634.62 + HMF 125 = 57,660 USD (58 percent effective rate on CIF).
Scenario B: no affidavit, default full invoice 232.
Section 232 at 50 percent on full invoice: 100,000 x 0.50 = 50,000 USD.
Total post-inclusion duty: 2,900 + 50,000 + 7,500 + 12,500 + 634.62 + 125 = 73,660 USD (74 percent effective rate on CIF).
Delta of Scenario A over current: 34,000 USD on 100k CIF, or 34 percent effective rate increase.
Delta of Scenario B over current: 50,000 USD, or 50 percent effective rate increase.
For a school district buying 200 trumpets at 500 USD landed each in the current stack (100k order), the post-inclusion price passes through to something like 750 to 900 USD per instrument depending on affidavit posture. That is a real budget hit for K-12 music programs already stretched.
Comment framing angles for music-industry importers
Federal Register 2026-15961 is genuinely on the fence for musical instruments. Section 232 requires that the article at issue impair national security. Trumpets and trombones are not defense-critical. Comment framing angles that have moved BIS in past comment windows.
Angle 1: national-security nexus challenge. Brass-wind musical instruments have no defense application. The DoD does not stockpile trumpets or tubas as strategic materiel. Military bands buy through GSA at commercial market rates. Argue that the statutory basis (19 USC 1862 national security determination) is not met for consumer musical instruments and that BIS should exclude 9205.10 from the derivative annex on that ground alone.
Angle 2: downstream user hardship with a sympathetic constituency. K-12 school music programs are a bipartisan sympathetic downstream user. Quantify the price pass-through per instrument and per school district budget. Attach data from NAMM (National Association of Music Merchants) or NAfME (National Association for Music Education) on program enrollment and instrument replacement cycles.
Angle 3: US domestic capacity is limited for the affected price tiers. Bach, Conn, King, Kanstul, Schilke, Getzen do produce US-origin instruments but at the intermediate and professional price tiers. Entry-level education market volume is not served by domestic capacity. Argue that inclusion does not achieve the national-security objective (no domestic-substitution benefit) but does raise costs on school music programs.
Angle 4: technical scope narrowing. If the political case for inclusion is unwinnable, argue for narrow scope: exclude finished instruments (9205.10) and limit inclusion to raw brass mill product (chapter 74 sheet, tube, rod) which is where the copper policy objective actually attaches. Alternatively, exclude finished instruments below a de minimis price point (education-tier at under 1,000 USD FOB per unit).
Angle 5: affidavit-or-default rule application. Even if inclusion is adopted, argue that the affidavit requirement should be simplified for consumer musical instruments (copper content by nominal alloy specification rather than lot-level metallurgical certification). Full metallurgical certification per lot is impractical at the education-tier price point.
What to do this week if you import brass-wind instruments
Three things.
One. File a substantive comment on regulations.gov before 11:59 PM ET Aug 27. Attach volume and price data. Coordinate with NAMM and NAfME if you have a trade association channel.
Two. Get producer affidavits on standing POs identifying copper content share by weight and by value, plus smelt or refine country of origin for the copper. Nominal alloy composition (63 percent Cu 37 percent Zn for yellow brass, 70/30 for cartridge brass) plus mill test certificate for the tubing lot is the typical documentation package.
Three. Evaluate alternative sourcing from UK (25 percent 232 rate under EPD), Germany (subject to 50 percent general), Japan and Taiwan (50 percent general), and US domestic (Bach, Conn, King, Kanstul, Schilke, Getzen) for the affected price tiers. Qualification is fast for professional and intermediate instruments but slow for education-tier bulk contracts.
For readers modeling the copper stack across origin and product classifications, our Section 232 aluminum vs copper vs steel derivative comparison covers the three-regime interaction and the copper affidavit mechanics in detail.
The window closes Aug 27. Filing takes 30 minutes to two hours depending on how much attached data you include. Not filing means the annex language locks in without your input.
Frequently asked questions
Why are brass-wind musical instruments on a metals derivative rule?
Brass is a copper-zinc alloy, typically 70 percent copper and 30 percent zinc for cartridge brass or 63 percent copper and 37 percent zinc for yellow brass. Copper is covered under Section 232 as of June 2026 (Proclamation 11021). BIS is treating brass-wind instruments as a copper derivative article for the same reason it treats insulated copper conductors and copper pipe fittings as derivatives: the finished good contains a material share of covered metal that would otherwise escape the 232 regime by classification at the finished-good level. The inclusion targets copper content in trumpets, trombones, French horns, tubas, cornets, flugelhorns, and their parts.
What HS subheadings does the proposal cover?
HS 9205.10 is the primary heading for brass-wind musical instruments. US 8-digit statistical breakouts include 9205.10.00 brass-wind instruments with subordinate breakouts for trumpets, cornets, and flugelhorns (9205.10.0020), trombones (9205.10.0040), French horns (9205.10.0060), tubas and other low brass (9205.10.0080). Parts and accessories fall under 9205.90.20 valves, slides, mouthpieces, and similar components. The Fed Reg 2026-15961 proposal covers 9205.10 finished instruments plus 9205.90 parts and accessories where the parts contain a material share of copper alloy content.
Who imports brass-wind musical instruments into the US?
Four main buyer categories: (1) school music programs (K-12 school districts and higher education) buying entry-level and intermediate instruments in bulk on multi-year contracts through educational distributors, (2) professional musicians and orchestras buying premium instruments (Bach, Yamaha, Schilke, Conn-Selmer) at 3,000 to 20,000 USD per instrument, (3) retail chains and specialty music stores (Sam Ash, Guitar Center, Music and Arts, Woodwind and Brasswind) stocking inventory across price tiers, (4) military bands and municipal ensembles buying through DLA or GSA contracts. Import origin is heavily concentrated: Yamaha (Japan and Indonesia), Jupiter and Mendini (Taiwan), Blessing (China), Wisemann and Cecilio (China), Bach and King (Mexico for Conn-Selmer entry-level, US for professional line).
What is the current MFN duty on HS 9205?
HS 9205.10 finished brass-wind instruments: MFN column 1 rate 2.9 percent ad valorem. HS 9205.90.20 parts and accessories: MFN column 1 rate 2.9 percent ad valorem. Both classifications currently pay Section 301 List 4A at 7.5 percent for China origin (via 9903.88.15). Both pay Section 301 forced-labor tier A or B depending on origin (China tier A at 12.5 percent under 9903.05.37 effective July 24 2026). No Section 232 layer applies today, because the finished-good classification under chapter 92 is outside the current 232 derivative annex.
What is the projected duty stack once brass-wind inclusion takes effect?
For a 100,000 USD CIF shipment of Chinese-origin trumpets at HS 9205.10.0020, post-inclusion stack: MFN 2.9 percent (2,900), plus S232 at 50 percent general on brass copper content share (typically 65 to 70 percent copper by weight, so 50 percent x 0.68 = 34 percent effective on invoice = 34,000), plus S301 List 4A 7.5 percent (7,500), plus S301 forced-labor tier A 12.5 percent (12,500), plus MPF cap 634.62, plus HMF 125, total duty around 57,660 USD versus current 25,660 USD. Delta of 32,000 USD on 100k CIF, or 32 percent effective rate increase. Without an affidavit identifying the copper content share, the default full-invoice 232 at 50 percent applies (50,000 USD 232 layer instead of 34,000), pushing the delta to 48,000 USD.
Is this a copper derivative flag or a steel derivative flag?
The Federal Register 2026-15961 notice describes the proposal as covering aluminum, steel, and copper derivative articles, and brass-wind instruments fall under the copper derivative flag based on the copper-zinc alloy composition of the brass tube and valve assemblies. Steel content in brass-wind instruments is limited to spring components in the valves and some hardware (typically less than 5 percent by weight), so the steel derivative flag would not apply on a metal-content basis. The affidavit at entry should identify copper content share by weight or value plus smelt or refine country of origin for the copper. Yellow brass at 63 percent copper and cartridge brass at 70 percent copper are the most common alloys for wind instruments.
