What a $295 advisory actually looks like

Why the Korean below? The full advisory is in English. Importers sourcing from Korea can request an optional Korean-language executive summary for their supplier or overseas team — it's shown here so you can see it. If you don't need it, skip past it; nothing in the English report depends on it.

Executive Summary

Facts — merchandise in its imported condition

Two facts drive the classification: the device's only active function is LED light emission, and it is sold to consumers, not medical practitioners. If your device adds massage or microcurrent, the analysis changes — see the counterpoint rulings in Section III.

Classification Analysis

Classification under the HTSUS is governed by the General Rules of Interpretation (GRI) — the standard CBP rules for picking the right code when more than one could apply. They're worked in sequence: GRI 1 classifies according to the terms of the headings and any relative section or chapter notes; GRI 3 resolves goods that could fall under two or more headings; GRI 6 applies the same rules one level down, at the subheading. In plain terms, this section shows which code the goods land in and why the competing ones don't.

Recommended: 8543.70.98.60 — ADOPTED

Column-1 general rate: 2.6% · KORUS special rate: Free

Under GRI 1, the mask is an electrical apparatus with an individual function (phototherapy) not covered by a more specific heading. Chapter 90 headings fail: it is not mechano-therapy (9019 — no mechanical action), and CBP declines 9018 (medical instruments) for devices "routinely sold to individuals, not to those in the professional practice of medicine." It is not a "lamp" of 8539 — it is an apparatus incorporating LEDs, not an LED light source itself, which is why the five rulings cited below place these devices in 8543.70 rather than 8539.

CBP precedent (CROSS rulings — click any number to verify at rulings.cbp.gov)

Five rulings support 8543.70.98 for consumer LED masks. Every number below links to its record on CBP's CROSS database so you can read the holding yourself.

On the code format: the full statistical reporting number is the 10-digit 8543.70.98.60 — the last two digits (.60) are the statistical suffix used on the entry line. The legal duty rate and any FTA / §301 footnote attach at the 8-digit subheading (8543.70.98), which is why references to the rate and the KORUS special column below cite the 8-digit line; older rulings still show the pre-renumber statistical line. 8543.70.96.50 → 8543.70.99.60 → 8543.70.98.60 are successive renumberings of the same legal line (shown in the schedule's dotted 4-2-2-2 format: heading, subheading, tariff-rate line, statistical suffix); the engine merges them at the 6-digit subheading so a retired line does not silently drop its precedent, and flags the lineage assumption for the reviewer. A related ruling, NY N246248 (the "illuMask" mask), is discussed under the rejected 9019 candidate below.

Counterpoint — when 9019 wins. NY N294596 (2018) and NY N349127 (2025-06-13) classified devices combining LED with massage or microcurrent under 9019.10.2020 (Free). If your SKU has these functions, a 9019 claim is defensible — document the mechanical function prominently.

Candidates rejected — and why

The value of the advisory is as much in what it rejects as what it adopts. Each alternative below is facially plausible; each fails for a documented reason.

9018.20.00.80 — UV/IR apparatus (Free) — NOT ADOPTED

Facially plausible, and the Free rate is tempting, but the consumer-sale line of rulings above forecloses it. Claiming a Chapter 90 "medical" code also invites FDA scrutiny (Section VI) for a zero duty benefit today.

8539.52.00 — LED lamps (2%) — NOT ADOPTED

No ruling support. A mask is an apparatus that incorporates LEDs; it is not a lamp.

6307.90.98 — textile "mask" of other made-up articles (7%) — NOT ADOPTED

This is the code a broker reaching for the word "mask" often lands on, and it carries the highest rate of any candidate. The rulings under it cover disposable nonwoven face masks and KN95 respirators — a different article in function and material. Adopting it would overpay on every shipment and would not survive a CF-28.

Holding

The applicable subheading for the subject merchandise will be 8543.70.98.60. The column-1 general rate of duty is 2.6%; the special-program rate is Free for qualifying origins, which include KR (KORUS). Duty rates are provided for convenience and are subject to change; verify against the current HTSUS at the time of entry.

Duty & Trade-Remedy Exposure (as of 2026-07-09)

Reading: classification choice moves $0 today. The levers are the KORUS claim (−$294.64/$10k versus unclaimed) and entry timing (−$1,000/$10k if the sunset holds).

Policy timeline & volatility (re-verify before each shipment)

HTS footnote overlay on 8543.70.98: "See 9903.88.02." — origin-dependent Section 301/232 exposure; confirm for your supply chain. Flagged HIGH in QC.

Savings & Refund Opportunities

1. KORUS FTA claim. "KR" appears in the special-rate subcolumn for 8543.70.98. To claim: goods must qualify as Korean-originating under KORUS rules of origin (for 8543.70, generally a tariff-shift rule satisfied by Korean assembly — verify against your BOM; significant Chinese LED/PCB content requires a rule-of-origin check), and you need a certification of origin at entry. KORUS entries are also MPF-exempt. Saves ~$294.64 per $10,000 versus an unclaimed entry.
2. IEEPA refund screen. The IEEPA reciprocal tariffs were voided by the Supreme Court on 2026-02-20; the refund pool is ~$166B with mechanics unresolved. If you paid the 15% IEEPA rate on entries between Aug 2025 and Feb 2026, you are likely refund-eligible. We run a refund-eligibility scan from your ACE entry report as a separate engagement.
3. Entry timing. Section 122's 10% is scheduled to sunset 2026-07-24. Deferrable shipments entered after the sunset approach $0 duty on the KORUS path. Confirm sunset status the week of 07-21 before booking — extension risk is real.
4. Binding ruling. For binding certainty before committing to large volumes, file a CBP ruling request citing the N246248/N352818 line. CBP's own fee is $0; we prepare the request for a flat $750.

Reasonable Care — how to use this advisory

CBP's Reasonable Care checklist asks importers, among other things, whether they consulted the HTSUS, CBP rulings on CROSS, and informed-compliance publications; whether they consulted a customs expert; and whether they follow the advice received and keep a written record of it. This advisory is designed to be that written record.

• HTSUS provisions and CROSS rulings consulted — cited throughout Section III (all rulings verified against rulings.cbp.gov on the report date)
• Written classification analysis with GRI reasoning — Section III
• Duty and trade-remedy exposure documented — Section IV
• Retain this advisory with your entry documents for five (5) years from the date of entry (19 C.F.R. Part 163)
• Provide any missing facts noted in Section II and obtain the updated advisory
• If confidence is below HIGH, obtain a binding ruling before high-volume entries

FDA note (independent of HTS)

HTS code and FDA jurisdiction are independent. LED masks marketed with acne or wrinkle treatment claims are FDA Class II medical devices (typically 510(k); "general wellness" positioning may be exempt) and require FDA entry data at import regardless of the 8543 classification. Align marketing claims with your regulatory posture before the first shipment.

Certification

This advisory is an informational classification analysis prepared to support the importer's reasonable-care obligations. It is not customs brokerage or legal advice, and it is based solely on the facts stated in Section II; a material change in those facts changes the analysis. Final classification responsibility rests with the importer of record. Binding certainty is available only through a CBP ruling under 19 C.F.R. Part 177.

A different product, the same method

To show the engine isn't tuned to one answer, here is a second real run: a vacuum-insulated stainless-steel tumbler from Korea. Note that the interesting question here is the opposite of the mask's — two headings genuinely compete, and the advisory says so honestly.

Holding & the honest tension

The recommended code is 7323.93.00 — "table, kitchen or other household articles, of stainless steel" — at 2% general, Free under KORUS. It's supported by ten CBP rulings on insulated stainless tumblers, most from 2018.

But the advisory does not hide the competing line. 9617.00.10 ("vacuum flasks and other vacuum vessels") at 7.2% has three supporting rulings, including N356922 (2026-01-28) and a 2021 revocation (H303684) that moved some drinkware into 9617. This is a live classification question, not a settled one. That's exactly the case where the confidence band, the rejected-candidate reasoning, and the binding-ruling recommendation earn the fee — you are told where the risk is instead of handed a single number to trust blindly.

Sources: hts.usitc.gov REST API and rulings.cbp.gov, both queried live. Policy data: policy.json v2026-07-09. The 9617 row shows why the binding-ruling option matters when two headings are ~5 points apart.
