Sourcing microphone cables from China
Heading 8544 has UK duty rates of 0% or 2% from China, but ordinary microphone leads usually fall on a 2% line. Finished cables must meet applicable hazardous-substance rules; low signal voltage does not remove that check. Specify wiring, shielding and strain relief. Cambridge China Bridge sources microphone cables.
Microphone leads usually carry 2% duty
Read from the UK Trade Tariff on 30 September 2026, heading 8544 covers insulated electrical conductors, including cable fitted with connectors. Ordinary terminated microphone leads are usually candidates for 8544 42 90 90 at 2%. Unterminated cable depends on construction, voltage and individual conductor wire diameter. The heading also contains 0% telecommunications lines, but do not assume an audio lead qualifies.
The selected lines carry 2% duty from China, with no anti-dumping or countervailing duty and no attached import controls in the supplied snapshot. Suspensions on the terminated and coaxial lines cover specified cable designs or offshore wind manufacture under authorised use. They are not a general microphone-cable exemption; budget the ordinary rate unless eligibility is confirmed.
Confirm the commodity code using the cable drawing, rated voltage, conductor construction and connector details. The table gives classification candidates, not interchangeable choices. For the wider heading and coaxial construction, see coaxial cable.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Other conductors fitted with connectors, including ordinary microphone leads | 8544 42 90 90 | 2% | None |
| Other unterminated cable rated up to 80 V | 8544 49 93 90 | 2% | None |
| Unterminated cable with individual conductor wires over 0.51 mm diameter | 8544 49 91 00 | 2% | None |
| Other coaxial cable, where the microphone cable has coaxial construction | 8544 20 00 90 | 2% | None |
Specify the signal path and connector assembly
State whether the cable carries a balanced or unbalanced microphone signal. Give the connector type, contact arrangement, mating equipment and complete wiring diagram, including shield termination. Specify copper conductor material, strand construction, conductor resistance, shielding construction, capacitance, sheath flexibility, finished length and tolerances. Agree whether branded connectors or approved equivalents are acceptable.
Approve a sample with the microphone and input equipment you will use. Check connector latching, handling noise and performance while flexing the cable near each connector. Specify strain relief that grips the sheath, rather than leaving the solder joints to carry a pull.
Finished microphone cables fall within hazardous-substance restrictions unless an exclusion applies. Request material evidence for sheath, insulation, solder and contact plating. Confirm with the relevant authority whether electrical safety regulations apply to the cable's rated voltage and intended use, and check product safety regardless. For cables sold as finished products to end users, also assess electrical waste obligations. Arrange testing and certification against the actual product.
Worked duty example
Illustrative example, not a quote: Illustrative batch of finished microphone leads for an audio equipment retailer under 8544 42 90 90, invoiced at £1,100 free on board, with £600 of freight and insurance to the UK. The customs value is £1,700. Duty at 2% is £34. Import VAT at 20% is charged on the customs value plus duty, £1,734, so it is £346.80. Import taxes total £380.80; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £34 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Wiring: check continuity against the approved diagram, shield connections and absence of shorts; retain factory test records.
Materials: strip samples to check copper construction, strand dimensions, shielding and sheath against the agreed specification.
Connectors: check contact fit, latch operation, solder workmanship and strain relief; repeat electrical checks while flexing the cable.
Arrival: check lengths, product identification, packing damage and handling noise using the approved equipment. Set the inspection scope with the quality inspection guide.

What goes wrong
A cable can pass a stationary continuity check yet crackle when moved because of a weak solder joint or ineffective strain relief. Wrong shield termination, crossed contacts and an unapproved connector substitution can make an otherwise intact cable unsuitable for your equipment.
A soft sheath does not establish conductor quality or shielding performance. Compare bulk samples with the retained sample and investigate material changes before accepting the batch. Do not treat a generic supplier certificate as evidence for the actual sheath, solder and connector combination.

Frequently asked questions
What is the UK import duty on microphone cables from China?
Ordinary finished leads are usually candidates for 8544 42 90 90 at 2%. The selected loose and coaxial cable lines also carry 2%. Confirm construction and use before choosing a code.
Are loose microphone cable and finished leads classified alike?
Usually not. Connectors, coaxial construction, rated voltage and individual conductor wire diameter affect classification. Supply the drawing and specification to your customs broker.
Do low-voltage microphone cables need compliance checks?
Yes. Low signal voltage does not remove hazardous-substance checks. Confirm with the relevant authority which electrical safety requirements apply, and check that the product is safe for its intended use.
How should I test a microphone cable sample?
Check wiring and shorts, then use your microphone and input equipment. Flex near the connectors, listen for crackle and handling noise, and check latching and strain relief.
