**SUPPLEMENTARY INFORMATION:**
**Background**
On August 3, 2009, Commerce published in the *Federal Register* the AD order on lawn groomers from China. [^1] On July 1, 2025, the ITC instituted, [^2] and Commerce initiated, [^3] the third sunset review of the *Order,* pursuant to section 751(c) of the Tariff Act of 1930, as amended (the Act). As a result of its review, Commerce determined that revocation of the *Order* would likely lead to the continuation or recurrence of dumping, and therefore, notified the ITC of the magnitude of the margins of dumping likely to prevail should the *Order* be revoked.

On March 10, 2026, the ITC published its determination, pursuant to sections 751(c) and 752(a) of the Act, that revocation of the *Order* would likely lead to continuation or recurrence of material injury to an industry in the United States within a reasonably foreseeable time. [^5]

**Scope of the Order**
The scope of this *Order* covers certain non-motorized tow behind lawn groomers, manufactured from any material, and certain parts thereof. Lawn groomers are defined as lawn sweepers, aerators, dethatchers, and spreaders. Unless specifically excluded, lawn groomers that are designed to perform at least one of the functions listed above are included in the scope of this *Order,* even if the lawn groomer is designed to perform additional non-subject functions ( *e.g.,* mowing).
All lawn groomers are designed to incorporate a hitch, of any configuration, which allows the product to be towed behind a vehicle. Lawn groomers that are designed to incorporate both a hitch and a push handle, of any type, are also covered by the scope of this *Order.* The hitch and handle may be permanently attached or removable, and they may be attached on opposite sides or on the same side of the lawn groomer. Lawn groomers designed to incorporate a hitch, but where the hitch is not attached to the lawn groomer, are also included in the scope of the *Order.*
Lawn sweepers consist of a frame, as well as a series of brushes attached to an axle or shaft which allows the brushing component to rotate. Lawn sweepers also include a container (which is a receptacle into which debris swept from the lawn or turf is deposited) supported by the frame. Aerators consist of a frame, as well as an aerating component that is attached to an axle or shaft which allows the aerating component to rotate. The aerating component is made up of a set of knives fixed to a plate (known as a “plug aerator”), a series of discs with protruding spikes (a “spike aerator”), or any other configuration, that are designed to create holes or cavities in a lawn or turf surface. Dethatchers consist of a frame, as well as a series of tines designed to remove material ( *e.g.,* dead grass or leaves) or other debris from the lawn or turf. The dethatcher tines are attached to and suspended from the frame. Lawn spreaders consist of a frame, as well as a hopper ( *i.e.,* a container of any size, shape, or material) that holds a media to be spread on the lawn or turf. The media can be distributed by means of a rotating spreader plate that broadcasts the media (“broadcast spreader”), a rotating agitator that allows the media to be released at a consistent rate (“drop spreader”), or any other configuration.
Lawn dethatchers with a net fully-assembled weight ( *i.e.,* without packing, additional weights, or accessories) of 100 pounds or less are covered by the scope of the *Order.* Other lawn groomers—sweepers, aerators, and spreaders—with a net fully-assembled weight ( *i.e.,* without packing, additional weights, or accessories) of 200 pounds or less are covered by the scope of the *Order.*
Also included in the scope of the *Order* are modular units, consisting of a chassis that is designed to incorporate a hitch, where the hitch may or may not be included, which allows modules that perform sweeping, aerating, dethatching, or spreading operations to be interchanged. Modular units—when imported with one or more lawn grooming modules—with a fully assembled net weight ( *i.e.,* without packing, additional weights, or accessories) of 200 pounds or less when including a single module, are included in the scope of the *Order.* Modular unit chasses, imported without a lawn grooming module and with a fully assembled net weight ( *i.e.,* without packing, additional weights, or accessories) of 125 pounds or less, are also covered by the scope of the *Order.* When imported separately, modules that are designed to perform subject lawn grooming functions ( *i.e.,* sweeping, aerating, dethatching, or spreading), with a fully assembled net weight ( *i.e.,* without packing, additional weights, or accessories) of 75 pounds or less, and that are imported with or without a hitch, are also covered by the scope.
Lawn groomers, assembled or unassembled, are covered by this *Order.* For purposes of this *Order,* “unassembled lawn groomers” consist of either (1) all parts necessary to make a fully assembled lawn groomer, or (2) any combination of parts, constituting a less than complete, unassembled lawn groomer, with a minimum of two of the following “major components”:
(1) an assembled or unassembled brush housing designed to be used in a lawn sweeper, where a brush housing is defined as a component housing the brush assembly, and consisting of a wrapper which covers the brush assembly and two end plates attached to the wrapper;
(2) a sweeper brush;
(3) an aerator or dethatcher weight tray, or similar component designed to allow weights of any sort to be added to the unit;
(4) a spreader hopper;
(5) a rotating spreader plate or agitator, or other component designed for distributing media in a lawn spreader;
(6) dethatcher tines;
(7) aerator spikes, plugs, or other aerating component; or
(8) a hitch, defined as a complete hitch assembly comprising of at least the following two major hitch components, tubing and a hitch plate regardless of the absence of minor components such as pin or fasteners. Individual hitch component parts, such as tubing, hitch plates, pins or fasteners are not covered by the scope.
The major components or parts of lawn groomers that are individually covered by this *Order* under the term “certain parts thereof” are: (1) brush housings, where the wrapper and end plates incorporating the brush assembly may be individual pieces or a single piece; and (2) weight trays, or similar components designed to allow weights of any sort to be added to a dethatcher or an aerator unit.
The scope of this *Order* specifically excludes the following: (1) agricultural implements designed to work ( *e.g.,* churn, burrow, till, etc.) soil, such as cultivators, harrows, and plows; (2) lawn or farm carts and wagons that do not groom lawns; (3) grooming products incorporating a motor or an engine for the purpose of operating and/or propelling the lawn groomer; (4) lawn groomers that are designed to be hand held or are designed to be attached directly to the frame of a vehicle, rather than towed; (5) “push” lawn grooming products that incorporate a push handle rather than a hitch, and which are designed solely to be manually operated; (6) dethatchers with a net assembled weight ( *i.e.,* without packing, additional weights, or accessories) of more than 100 pounds, or lawn groomers—sweepers, aerators, and spreaders—with a net fully-assembled weight ( *i.e.,* without packing, additional weights, or accessories) of more than 200 pounds; and (7) lawn rollers designed to flatten grass and turf, including lawn rollers which incorporate an aerator component ( *e.g.,* “drum-style” spike aerators).
The lawn groomers that are the subject of this *Order* are currently classifiable in the Harmonized Tariff Schedule of the United States (HTSUS) statistical reporting numbers 8432.41.0000, 8432.42.0000, 8432.80.0000, 8432.80.0010, 8432.90.0060, 8432.90.0081, 8479.89.9496, [^6] 8479.90.9496, and 9603.50.0000. These HTSUS provisions are given for reference and customs purposes only, and the description of merchandise is dispositive for determining the scope of the product included in this *Order.*
[^6] Effective January 27, 2022, HTSUS code 8479.89.9496 was replaced by 8479.89.9596.
**Continuation of the Order**
As a result of the determinations by Commerce and the ITC that revocation of the *Order* would likely lead to continuation or recurrence of dumping and material injury to an industry in the United States, pursuant to section 751(d)(2) of the Act, Commerce hereby orders the continuation of the *Order.* U.S. Customs and Border Protection will continue to collect AD cash deposits at the rates in effect at the time of entry for all imports of subject merchandise.
The effective date of the continuation of the *Order* will be March 10, 2026. [^7] Pursuant to section 751(c)(2) of the Act and 19 CFR 351.218(c)(2), Commerce intends to initiate the next five-year reviews of the *Order* not later than 30 days prior to fifth anniversary of the date of the last determination by the ITC.
