Every LED lighting product entering the United States must be classified under a single 10-digit Harmonized Tariff Schedule (HTS) code. That code determines your duty rate, flags your shipment for Section 301 tariffs, and sets your audit risk profile with CBP. This guide walks through the complete HTS classification framework for LED products in 2026 — from the decision tree that narrows your code to the exact documentation CBP expects at the port of entry.
The Harmonized Tariff Schedule of the United States (HTSUS) organizes goods into 99 chapters. LED lighting products split between two chapters, and picking the wrong one is the most expensive mistake importers make.
| Chapter | Scope | Key Heading | Covers |
|---|---|---|---|
| Chapter 94 | Furniture; bedding, mattresses, lamps and lighting fittings; illuminated signs | 9405 | Luminaires and lighting fittings including complete fixtures with housing, chandeliers, wall/ceiling fittings, and parts of lamps and lighting fittings |
| Chapter 85 | Electrical machinery and equipment; sound recorders; television image recorders | 8539 | LED lamps (bulbs/replacement lamps), LED modules, LED light sources that are not integrated into a fixture housing |
| Chapter 85 | Electrical machinery (continued) | 8504 | LED drivers and power supplies — separately classified regardless of whether shipped with the fixture |
The first 6 digits are globally harmonized (the "HS code" used by 200+ countries). Digits 7-10 are country-specific. The United States adds 4 digits for tariff-rate lines. Example: 9405.40.6000 breaks down as 94 (Chapter), 05 (Heading — lamps/luminaires), 40 (Subheading — electric), 6000 (Statistical suffix — LED luminaires).
Work through these questions in order. Each answer narrows the field. If you reach a grey area, consult a licensed customs broker — CBP penalties for misclassification range from 5.5% to 19.7% of the undeclared value depending on negligence level.
→ YES: Continue to Q2. → NO: It's likely a lamp, module, or component — skip to Q5.
→ YES: → 9405.40.6000 (LED luminaires, 3.9% base + Section 301)
→ NO (fluorescent, HID, incandescent): → 9405.40.8000 (Other electric lamps and lighting fittings, 3.9% base)
Includes chandeliers, sconces, pendant fixtures with decorative value beyond pure illumination.
→ YES: → 9405.10.0000 (Chandeliers and other ceiling/wall electric fittings, 3.9% base)
Includes housings, diffusers, brackets, reflectors shipped without the light source.
→ YES: → 9405.99.4000 (Parts of lamps and lighting fittings, 4.7% base)
Screw-base (E26/E27), pin-base (GU10, G13, G24), or bayonet base LED replacements.
→ YES: → 8539.50.0000 (LED lamps, 0% base + Section 301)
Constant-current or constant-voltage LED drivers, whether shipped with a fixture or separately.
→ YES: → 8504.40.XXXX (Static converters/LED drivers — rate varies by sub-classification, typically 0-2.6% base)
All tariff rates are current as of the HTSUS 2026 Basic Edition. Section 301 rates reflect China-specific duties under the Trade Act of 1974, as modified through Presidential Proclamations. Section 301 rates are subject to change — always verify the current rate at hts.usitc.gov before filing entry.
| HTS Code | Product Description | Base MFN Rate | Section 301 (China) | Effective Total* | Notes |
|---|---|---|---|---|---|
| 9405.40.6000 | LED luminaires (fixtures with housing for LEDs) | 3.9% | +7.5% | 11.4% | Most common code for LED fixtures; includes LED high bays, panels, wall packs, floodlights |
| 9405.40.8000 | Other electric lamps and lighting fittings (non-LED) | 3.9% | +7.5% | 11.4% | Fluorescent, HID, incandescent fixtures; also a catch-all for unclassified electric fittings |
| 8539.50.0000 | LED lamps (bulbs, tubes, replacement lamps) | 0% | +7.5% | 7.5% | Includes screw-base, pin-base, and bayonet LED replacements; Section 301 applies despite base free rate |
| 9405.10.0000 | Chandeliers and other ceiling/wall electric fittings | 3.9% | +7.5% | 11.4% | Decorative fixtures including sconces, pendants, chandeliers — even with LED light source |
| 9405.99.4000 | Parts of lamps and lighting fittings | 4.7% | +7.5% | 12.2% | Housings, brackets, diffusers, reflectors shipped without light source; highest base rate in the group |
| 8504.40.6018 | LED drivers (constant-current, 50-150W typ.) | 0% | +7.5% | 7.5% | LED drivers as power supplies for lighting; confirm sub-classification at 10-digit level |
| 8504.40.7007 | LED drivers (constant-voltage, 50-150W typ.) | 2.6% | +7.5% | 10.1% | Constant-voltage drivers used in LED strip systems; verify wattage and voltage for exact sub-code |
| 8539.51.0000 | LED modules (light-emitting diode modules) | 0% | +7.5% | 7.5% | Bare LED modules or arrays without housing; used in luminaire manufacturing or retrofit |
| 9405.41.0000 | Photovoltaic (solar) luminaires — LED | 3.9% | +7.5% | 11.4% | Solar-powered LED lighting fixtures; classified under 9405.41 even with integrated solar panel |
| 8531.80.9000 | LED indicator panels and illuminated signs | 0% | +7.5% | 7.5% | Exit signs, emergency signage, light-boxes — NOT general illumination fixtures |
*Effective Total represents the estimated combined duty rate for imports of Chinese origin as of HTSUS 2026. Section 301 rates are subject to change via Federal Register notices. Importers from non-China origins (Mexico, Vietnam, India, EU) pay only the Base MFN Rate unless additional AD/CVD orders apply. Always consult a licensed customs broker for binding classification before entry.
The Section 301 investigation (Trade Act of 1974) authorizes the U.S. Trade Representative to impose additional duties on goods from China in response to unfair trade practices. LED lighting products are covered under multiple tranches of Section 301 tariffs. These duties sit on top of the base MFN rate and any antidumping/countervailing duty (AD/CVD) orders.
| List/Tranche | Coverage | Current Rate | Status |
|---|---|---|---|
| List 3 (2018) | 9405.40.6000, 9405.40.8000, 9405.10.0000, 9405.99.4000 — LED luminaires, chandeliers, parts | 7.5% | Active; periodic exclusion rounds open via USTR Federal Register notices |
| List 4A (2019) | 8539.50.0000 — LED lamps (bulbs/tubes) | 7.5% | Active; reduced from original 15% via Presidential action |
| List 4A (2019) | 8504.40 — LED drivers/power supplies | 7.5% | Active |
Classifying LED luminaires as 8539.50.0000 (LED lamps) to claim 0% base rate:
→ If caught by CBP audit: back duties at 3.9% + penalties (5.5% minimum negligence) + interest = $940+ for a single $10,000 entry
→ Deliberate misclassification (fraud): penalty up to 2× the lost revenue = $780 penalty + $390 back duty = $1,170 total
Using 9405.40.6000 with a successful Section 301 exclusion:
→ Base MFN: 3.9% = $390 | Section 301: EXCLUDED = $0 | Total duty: $390
→ Savings vs. full Section 301 rate: $750 per $10,000 order. On a container-load ($100,000), that's $7,500 per shipment.
The U.S. Trade Representative (USTR) opens periodic exclusion request windows via Federal Register notices. The process is competitive and requires detailed justification:
An LED luminaire assembled in Vietnam from Chinese-made LED boards, drivers, and aluminum housings — what's the country of origin? CBP applies the substantial transformation test: did the processing in the third country result in a new and different article of commerce with a different name, character, or use?
| Scenario | Origin Determination | Rationale |
|---|---|---|
| Chinese LED boards assembled into complete luminaire housings in Vietnam — with soldering, thermal management integration, and final testing | Vietnam | The assembly process transforms individual components into a functioning luminaire — a new article of commerce |
| Fully assembled Chinese luminaires re-packaged into retail boxes in Vietnam — no manufacturing, testing, or component integration | China | Repackaging alone is not substantial transformation; CBP considers this transshipment for tariff avoidance |
| Chinese LED chips (dies) wire-bonded and encapsulated into LED packages in Malaysia — then shipped to the US | Malaysia | Die-level packaging (wire bonding, phosphor coating, encapsulation) creates a new article — the LED package itself |
| Chinese-made LED modules inserted into US-made housings in Mexico — with wiring, driver connection, and UL testing | Case-by-case | Depends on the relative value, complexity, and whether the LED module vs. housing is considered the "essence" — seek a binding CBP ruling |
Every formal entry (value >$2,500) requires specific documentation. Missing or inconsistent paperwork is the #1 cause of CBP holds, exam flags, and liquidated damages claims. Here's exactly what CBP expects for LED lighting imports:
The CBP Form 7501 is the single most important document in your import transaction — it's your official declaration of value, classification, and duty payment. Learning to read it catches broker errors before they become your liability.
| Field | What It Means | What to Verify |
|---|---|---|
| Block 11 — Entry Number | Unique 11-digit entry identifier assigned by CBP | Record for your internal tracking; CBP uses this for all correspondence about the entry |
| Block 27 — HTSUS Number | The 10-digit HTS code declared for each line item | This is the most critical field to verify. Cross-check against this guide and your broker's recommendation. A wrong 10-digit code here is an enforceable misclassification |
| Block 33 — Entered Value | Transaction value of the merchandise in USD | Must match your commercial invoice; must include assists (tooling, components you provided) and packing costs per 19 CFR 152 |
| Block 36 — Duty Rate | The aggregate duty rate applied (base MFN + Section 301 + AD/CVD + any other) | Verify each layer separately: base rate, Section 301, and any additional duties. Brokers occasionally miss Section 301 applicability |
| Block 40 — Calculated Duty | Duty owed = entered value × duty rate | Math check — especially on multi-line entries. A decimal-point error on a $100K entry costs real money |
| Block 38 — Country of Origin | ISO country code (CN, VN, MX, IN, etc.) | Must match your COO certificate; "CN" (China) triggers Section 301 — ensure China is declared when applicable |
A lighting importer's broker classified 9405.40.6000 LED high bays as 9405.40.8000 ("other" non-LED fixtures) on a $75,000 entry. CBP post-entry audit found the misclassification 18 months later. Result: $2,925 in back duties (difference between codes was actually the same rate in this case, but the inaccuracy triggered a full audit revealing undervaluation on 3 other entries) + $9,400 in penalties. The importer is liable even if the broker made the error — per 19 USC 1484, the importer of record bears ultimate responsibility for the accuracy of entry declarations.
CBP uses predictive analytics to flag entries for review. Certain patterns in LED lighting imports consistently trigger examinations and audits. Here are the most common misclassification pitfalls and how to avoid them:
| Mistake | What Happens | CBP Audit Trigger | How to Fix |
|---|---|---|---|
| Classifying LED fixtures as LED lamps (9405.40.6000 → 8539.50.0000) | Underpaying 3.9% base MFN rate — the importer claims the 0% lamp rate on fixtures clearly in housings | Invoice descriptions showing "luminaire," "housing," or "fixture" with HTS 8539 — instant red flag match | Physical examination of the product: does it have a housing and mount? Use 9405.40.6000. Is it a bulb-only replacement? Use 8539.50.0000. |
| Declaring incorrect country of origin | Section 301 avoidance — declaring Vietnam/Mexico origin for goods substantially manufactured in China | CBP's transshipment targeting; factory addresses that mismatch known Vietnamese electronics manufacturing capacity | Obtain a CBP binding ruling (19 CFR Part 177) before entry if origin is ambiguous. Request supplier factory audit rights |
| Undervaluing entered merchandise | Declaring invoice value below actual transaction value to reduce duty; often paired with a "revised" invoice for bank purposes | Invoice value statistically below market for the product category; separate invoices for payment vs. customs | Declare the full transaction value per 19 USC 1401a. All assists (tooling, free-of-charge components) must be included |
| Omitting Section 301 from China-origin goods | Broker fails to add the Section 301 layer on top of the base MFN rate | China origin declared (Block 38: CN) but duty only shows base rate — CBP systems catch this automatically | Verify Block 36 on Form 7501 shows base rate + 301 rate. For 9405.40.6000 from China: Block 36 should read 11.4% (3.9% + 7.5%) |
| Using a catch-all code because "it's close enough" | 9405.40.8000 ("other electric lamps") instead of the specific 9405.40.6000 (LED) — or vice versa | Consistent use of generic/catch-all codes across entries suggests inadequate classification diligence | Always classify to the most specific 10-digit code. "Close enough" is not a legal standard under 19 CFR 177 |
| Violation Level | Penalty Range | Example on $10,000 Underpayment |
|---|---|---|
| Ordinary Negligence | 5.5% of lost revenue (minimum) | $550 minimum penalty |
| Gross Negligence | 19.7% of dutiable value (maximum) | Up to $1,970 on a $10,000 shipment + back duties |
| Fraud | Up to 2× the lost revenue | Up to $20,000 penalty + back duties + possible criminal referral |
Tariff engineering — legally structuring a product's design or supply chain to reduce duty liability — is a lawful practice recognized by CBP, provided the product's essential character is not misrepresented. Here are approaches relevant to LED lighting:
Import LED modules (8539.51.0000, 0% base), drivers (8504.40, 0-2.6% base), and empty housings (9405.99.4000, 4.7% base) as separate entries, then perform final assembly in the US. Each component is classified on its own merits. The combined duty may be lower than importing a finished luminaire at 3.9% base, particularly if US assembly creates "American-made" status for government procurement.
Catch: US assembly costs (labor, facility, inventory carrying) must be net cheaper than the duty savings. The break-even varies by product complexity — typically viable for higher-value commercial fixtures where the duty differential exceeds $15-20/unit.
Shift final assembly to Vietnam or Mexico where the substantial transformation test is met, removing China as the country of origin and eliminating Section 301 liability. Mexico adds USMCA benefits (duty-free on qualifying goods). Vietnam avoids Section 301 but requires genuine manufacturing investment — CBP audits Vietnam-origin intensively.
If you ship LED drivers as separate SKUs on a separate commercial invoice, they're classified independently under 8504.40. When bundled with the fixture but invoiced together with separate line items and HTS codes, CBP may still accept the split classification — but this is case-specific. Request a binding ruling if the duty savings are material.
CBP will issue a CF-28 (Request for Information) or CF-29 (Notice of Action). You have 20 days to respond with documentation supporting your classification. If CBP disagrees, they'll liquidate the entry at the correct (higher) rate and bill you for the difference plus interest. If they determine negligence or fraud, penalties are assessed on top. CBP has 314 days from entry date to liquidate or reliquidate an entry — but fraud has no statute of limitations.
For formal entries (value >$2,500), you are legally allowed to self-file, but it's strongly discouraged for LED lighting due to the complexity of HTS classification, Section 301 layering, and origin rules. A licensed customs broker's error is still your liability, but they have the systems (ABI/ACE) and knowledge to reduce the error rate dramatically. The broker fee ($75-150 per entry) is trivial compared to the cost of a single misclassification penalty.
Yes — if USTR has granted an exclusion for your specific product. Exclusions are product-specific, not importer-specific or HTS-code-wide. You must file the exclusion number on CBP Form 7501 at entry. Previously granted exclusions may be extended via Federal Register notice; monitor USTR announcements. If no exclusion exists for your product, you may petition USTR during an open comment period, but competition is intense — thousands of LED product exclusions are requested per cycle, and only a fraction are granted.
Yes — the base MFN rate applies regardless of origin. The difference is that non-China origins do not face the additional Section 301 duty layer. For example: LED luminaires (9405.40.6000) from Vietnam pay 3.9% (base only), while the same product from China pays 11.4% (3.9% base + 7.5% Section 301). Some countries also benefit from Free Trade Agreements (FTAs): Mexico/USMCA may allow duty-free treatment if the product qualifies under rules of origin. South Korea (KORUS FTA), Australia, and several others have preferential rates for qualifying goods.
The HS (Harmonized System) code is the first 6 digits, standardized across 200+ WCO member countries — it's used internationally on commercial invoices and shipping documents. The HTS (Harmonized Tariff Schedule) code is the full 10-digit US-specific version used for customs entry. The first 6 digits of an HTS code match the HS code exactly. Example: HS 9405.40 = HTS 9405.40.6000. Your supplier provides the HS code; your broker determines the HTS code for CBP.
Three-step verification: (1) Check the proposed 10-digit HTS code at hts.usitc.gov — read the official description and all chapter/section notes to confirm your product fits. (2) Cross-reference the code against CBP ruling letters at rulings.cbp.gov — search for your product type to see how CBP has classified similar goods. (3) If uncertain, request a CBP binding ruling (19 CFR Part 177) — this is the only legally binding classification that protects you from penalties if CBP later disagrees. A broker's verbal assurance is not binding.
LED strip lights (flexible PCB strips with SMD LEDs) typically fall under 8539.51.0000 (LED modules) if they are cuttable strips without power supply. If sold as a consumer kit with a driver and controller, the entire kit may be classified as a luminaire under 9405.40.6000 or as an LED lamp set — the classification depends on whether the kit constitutes a "complete lighting fitting." This is a frequent grey area; a binding ruling is recommended for commercial-scale imports.
