Preferential rates for China
China is not a party to any of the preference programs this line lists, so a Chinese origin cannot claim a Column 1 Special rate here: the general rate applies.
The line's special-rate cell reads
Free (A*,AU,BH,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG); in words, the programs it
points at are: GSP (Generalized System of Preferences), Australia FTA, Bahrain FTA, Chile FTA, Colombia TPA, AGOA (Africa Growth and Opportunity Act), CBI (Caribbean Basin Initiative), Israel FTA, Jordan FTA, Korea FTA (KORUS), Morocco FTA, Oman FTA, CAFTA-DR, Panama TPA.
Antidumping and countervailing duty
1 case document in our Federal Register case file matches both HS 940421 and a Chinese origin. These duties are not in the effective rate above: they are producer-specific, they are assessed on entry, and the deposit rate depends on which manufacturer shipped the goods. They can exceed the tariff itself.

How much China actually ships under HS 940421
The US imported $100,207.00 of HS 940421 from China in 2026-09, 0.3% of the code's $39,554,034.00 total and the #11 origin for it. Largest suppliers in the same month: INDONESIA ($25,853,125.00), VIETNAM ($4,962,502.00), MEXICO ($4,872,191.00), CANADA ($1,638,017.00). This is the Census general-imports series; it is value, not volume, so it does not move with a rate change on its own.
The 4 HTS lines under HS 940421
Mattress is classified at six digits as 940421. The US adds national digits below that, and the rate is set at the line, not at the six-digit code — so this page prices 9404.21.00, the line the schedule resolves the code to. If your goods sit on a different line, the rate above does not apply to them.
| HTS line | Description | Column 1 | Column 2 |
|---|---|---|---|
| 9404.21.00 | Of cellular rubber or plastics, whether or not covered ← priced above | 3% | 40% |
| 9404.21.00.10 | For use in a crib or toddler bed | 3% | 40% |

Frequently asked questions
What is the import duty on mattress from China?
40.5% of the declared value: 3% Column 1 general rate on HTS 9404.21.00 plus 37.5% of Chapter 99 additional duty for a Chinese origin. On $10,000.00 that is $4,050.00, before freight, insurance and any antidumping or countervailing deposit.
Can a Chinese exporter get a lower rate on this line?
Not through a trade preference on this line. The line lists special-rate programs, but China is not a party to any of them.
Is the rate the same for every HTS line under 940421?
No. HS 940421 covers 4 HTS lines and this page prices 9404.21.00. A different line under the same six digits can carry a different rate and a different Chapter 99 stack, which is why the calculator asks for the line rather than the code.
Is there an antidumping order on mattress from China?
Our Federal Register case file holds 1 matching case document, beginning with A-570-092 (Mattresses). AD/CVD is producer-specific and assessed at entry, so it is not part of the 40.5% above.
