Bluetooth water bottle HTS 3924.10.4000: why CBP called it plastic, not a speaker
GRI 1GRI 3(b)CBP classified the Bauhn 2-in-1 plastic water bottle with a Bluetooth speaker lid under HTS 3924.10.4000 at 3.4% because the plastic drinking vessel, not the speaker, carries the essential character of the composite good.
This is a composite good, so GRI 3(b) governs and the classification follows the component that gives essential character. Two headings realistically compete: heading 3924 for plastic household articles and heading 8518 for loudspeakers/audio equipment. CBP landed on 3924 because the plastic bottle dominates the bulk and weight and does the main job — holding a beverage — and it keeps doing that job with a dead battery. The speaker is a bolt-on feature in the lid, useful but secondary. That is why the audio heading was set aside even though the electronics are the marketing hook. Practitioners should note the reasoning is fact-driven: essential character rests on which component does the primary work and dominates the physical article, not on which part costs more or sells the product. Final classification depends on the importer's actual product and should be confirmed by a licensed customs broker.
- Confirm with the supplier which component dominates bulk/weight and describe the drinking function first on the commercial invoice.
- Verify current Section 301 Chapter 99 status for China-origin 3924 goods before you budget landed cost.
- Keep a spec sheet and photos showing the bottle works as a vessel independent of the battery, in case CBP verifies the facts.
| Path | Code | Base duty |
|---|---|---|
| Path CBP used — plastic household article | 3924.10.4000 | 3.4% |
| Alternative path — loudspeaker/audio illustrative | 8518.22.0000 | Free (base) |
| On a $40,000 shipment, 3924.10.4000 at 3.4% base = $1,360 in base duty; 8518.22.0000 base is Free. The gap looks large but essential character, not rate shopping, decides the heading. Note this is base-rate math only. If the goods are China-origin, a Section 301 add-on may stack on top; that assumes the goods remain subject to that measure at entry, so verify current Chapter 99 status and any exclusions before you rely on either figure. | ||
Illustrative comparison only. The alternative heading is one contrast possibility — the exact subheading for a different product configuration would need separate analysis (other Chapter 84/85 or specific provisions may apply). Any Section 301 / Chapter 99 figure assumes the goods remain subject to that measure at the time of entry; always verify the current Chapter 99 status and any applicable exclusions.
- Rate-shopping toward the free audio heading conflicts with GRI 3(b) when the plastic vessel dominates — expect challenge.
- Lithium battery in the lid triggers separate hazmat/transport and labeling rules independent of the tariff line.
- Any redesign where the speaker becomes the dominant component could shift the heading and the duty exposure.
- The electronics become the primary article (e.g. a speaker with a small water reservoir as an accessory) → Essential character could shift to the audio heading around 8518, changing the base rate and duty analysis.
- Bottle is metal (stainless steel) instead of plastic → Household article headings in Chapter 73/76 come into play instead of 3924, with different rates.
- The lid speaker is sold separately from the bottle → Each item is classified on its own — the speaker likely in 8518, the bare bottle in 3924 — no composite-good analysis.
The lesson I take from this one: CBP does not care that the speaker is the selling point. Essential character follows what the article physically is and does most of the time. If the plastic keeps holding water with a dead battery, it's a bottle with a gadget, and it prices as a bottle.
- Invoice should describe the primary drinking function first, speaker as a secondary feature.
- Get a component breakdown showing plastic share of bulk and weight.
- Obtain the lithium battery spec sheet and confirm transport/labeling compliance.
- State country of origin and pull the current Section 301 Chapter 99 status for 3924.
- Keep photos showing the bottle functions independent of the battery.
- Confirm the exact volume capacity and materials of the body and lid.
Why did CBP classify the Bluetooth water bottle under HTS 3924.10.4000 and not as a speaker?
Because it's a composite good and, under GRI 3(b), the plastic bottle gives the essential character — it dominates bulk and weight and still works as a drinking vessel with a dead battery. Final classification depends on your actual product; confirm with a licensed broker.
What is the duty rate for a plastic water bottle with a Bluetooth speaker under 3924.10.4000?
The ruling states a base rate of 3.4% ad valorem. If the goods are China-origin, a Section 301 add-on may apply on top — verify current Chapter 99 status and exclusions before budgeting.
Does Section 301 apply to a China-origin Bluetooth water bottle in HTS 3924?
It may. Section 301 measures reach many Chapter 39 lines from China, but rates and exclusions change. Check the current Chapter 99 / 9903 status for your exact subheading at time of entry with your broker.
Could the same product be classified as a loudspeaker under 8518 instead?
Not on these facts. CBP treated the speaker as secondary. If a similar product's electronics dominate the article, the audio heading (around 8518) could apply. Essential character is fact-driven, so confirm your specific item.
Does the lithium battery in the lid change the tariff classification?
No — the battery doesn't move the heading here, since the plastic vessel drives essential character. But it does trigger separate hazmat, transport and labeling requirements you need to handle apart from the tariff line.
What documents should I prepare to import a Bluetooth water bottle like this?
Invoice wording that leads with the drinking function, a component/weight breakdown, the battery spec sheet, origin details, product photos, and a current Section 301 review. Share the ruling control number with entry documents if it matches your product.
