Confirm classification
Start with the merchandise as imported. Complete buildings, component kits and heaters have received different treatment.
Duty research
A sauna's HTS code is not its full duty stack.
Classification establishes the tariff provision. The amount actually due can also depend on country of origin, Chapter 99 measures, free-trade rules, antidumping/countervailing duties and the entry date.
Current base-rate reference
As checked in September 2026, the general Column 1 rates associated with the tracked provisions are 2.6% for 9406.10.0000, 3.7% for 8516.29.0090 and 2.7% for 8516.79.0000. These are base rates only and must not be treated as a complete landed-duty calculation.
| Research category | Code | General base rate | Why sauna-relevant |
|---|---|---|---|
| Prefabricated buildings of wood | 9406.10.0000 | 2.6% | N304393; complete wooden sauna structure |
| Other electric space-heating apparatus | 8516.29.0090 | 3.7% | H179957; electric sauna heater |
| Other domestic electrothermic appliances | 8516.79.0000 | 2.7% | N333797; portable infrared sauna |
Base rates are provided as a research reference and can change. Verify the current HTSUS for the entry date.
Determine origin
Country of origin can require a separate substantial-transformation analysis. H343750 is a sauna-specific example involving Canada, China and Mexico.
Check additional measures
Review current Chapter 99 notes, Section 301 or Section 232 actions, AD/CVD scope and any applicable preference program before calculating the entry.
Wood-products trade-action watch
Do not assume 9406.10 is covered merely because a sauna is made of wood. The September 2025 Section 232 wood-products action uses specified tariff provisions and derivative-product lists. Sauna Import will only label a tracked code as covered when the governing annex or current official guidance supports that conclusion.
The 2025 wood-products proclamation also directed Commerce to provide an update by October 1, 2026 on hardwood timber/lumber and possible additional derivative products. That makes the exact tariff-line annex—not a product nickname—the controlling research starting point.
Primary checks before an entry
- Current HTSUS and Chapter 99 notes
- CBP CROSS for classification and origin precedent
- USTR Section 301 materials
- Commerce AD/CVD resources
