RE: The tariff classification of auxiliary audio cables from China
Dear Ms. Ratto:
In your letter dated November 22, 2025, you requested a tariff classification ruling.
The merchandise under consideration is identified by part number 301-00002-000.A2 and is described as an
auxiliary cable for use with aviation headsets. The part is comprised of a length of insulated cable with a
3.5mm audio connector at each end. You state that the cable allows the pilot to connect their smartphone or
other audio inputs to the aviation headset. This allows the pilot to use the headset to make phone calls, listen
to music, and receive critical alerts from navigational applications without relying on a Bluetooth connection.
The applicable subheading for the auxiliary cable, part number 301-00002-000.A2, will be 8544.42.2000,
Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Insulated (including
enameled or anodized) wire, cable (including coaxial cable) and other insulated electric conductors, whether
or not fitted with connectors; optical fiber cables, made up of individually sheathed fibers, whether or not
assembled with electric conductors or fitted with connectors: Other electric conductors, for a voltage not
exceeding 1,000V: Fitted with connectors: Other: Of a kind used for telecommunications.” The general rate
of duty will be free.
Effective March 4, 2025, pursuant to U.S. Note 2(u) to Subchapter III, Chapter 99, all products of China and
Hong Kong as provided by heading 9903.01.24, HTSUS, other than products classifiable under headings
9903.01.21, 9903.01.22, and 9903.01.23, HTSUS, will be subject to an additional 10 percent ad valorem rate
of duty. At the time of entry, you must report the applicable Chapter 99 heading, i.e. 9903.01.24, in addition
to subheading 8544.42.2000, HTSUS, listed above.
On July 30, 2025, Presidential proclamation 10962 imposed additional tariffs on certain semi-finished copper
and intensive copper derivative products. Additional duties for semi-finished copper and intensive copper
derivative products of 50 percent upon the value of the copper content are reflected in Chapter 99, heading
9903.78.01. The non-copper content of these products, provided for in heading 9903.78.02, is not subject to
the additional ad valorem duties. At the time of entry, for the copper content you must report heading
9903.78.01, in addition to subheading 8544.42.2000, HTSUS. For the non-copper content, you must report
heading 9903.78.02, in addition to subheading 8544.42.2000, HTSUS.
Effective April 5, 2025, Executive Orders implemented “Reciprocal Tariffs.” All imported merchandise must
be reported with either the Chapter 99 provision under which the reciprocal tariff applies or one of the
Chapter 99 provisions covering exceptions to the reciprocal tariffs. At this time, products of China will be
subject to an additional ad valorem rate of duty of 10 percent. For products covered by heading 9903.78.01
this additional duty applies to the non-copper content of the merchandise. At the time of entry, you must
report the Chapter 99 heading applicable to your product classification, i.e. 9903.01.25, in addition to
subheading 8544.42.2000, HTSUS, listed above.
Pursuant to U.S. Note 20 to Subchapter III, Chapter 99, HTSUS, products of China classified under
subheading 8544.42.2000, HTSUS, unless specifically excluded, are subject to an additional 25 percent ad
valorem rate of duty. At the time of importation, you must report the Chapter 99 subheading, i.e., 9903.88.03,
in addition to subheading 8544.42.2000, HTSUS, listed above.
The HTSUS is subject to periodic amendment so you should exercise reasonable care in monitoring the status
of goods covered by the Note cited above and the applicable Chapter 99 subheading. For background
