Section 301 tariff check for PCB assembly from China

Planning Use only. Broker review required for Entry Use.

A PCB assembly from China can be a populated board, controller module, power board, LED board, motor-control board, sensor board, or board shipped with harnesses and enclosure parts. Section 301 exposure depends on the supported HTS candidate and China origin record.

Use this page to prepare a Planning Use file before a duty estimate is used.

quick answer

For "section 301 tariff PCB assembly from China", collect board function, populated components, programmed status, intended device, voltage, connectors, harnesses, enclosure parts, origin support, supplier code, and value. Then check the sourced HTS candidate against current USTR Section 301 material.

Do not rely on "PCB assembly" without the board function.

facts to collect for a PCB assembly

Collect:

Invoice wording, SKU, model number, bill of materials excerpt, drawing, and photos.
Board function: motor control, LED driver, power conversion, sensor interface, display control, radio, or general controller.
Populated components: ICs, transformers, relays, capacitors, resistors, connectors, sensors, LEDs, heat sinks, or fuses.
Programmed firmware, test status, conformal coating, serial labels, and quality marks.
Voltage, current, protocol, connector count, cable harnesses, and intended host device.
Set contents: board only, harnesses, housing, screws, bracket, label, or service kit.
Country of origin evidence for PCB fabrication, SMT, through-hole insertion, programming, testing, and packing.
Supplier HS or HTS code and notes.
Unit value, assists, freight, insurance, and shipment timing.

Keep top and bottom board photos with connector labels visible.

missing facts

Mark the file incomplete when:

Function is unclear.
Populated component list is missing.
Programmed versus unprogrammed status is unsupported.
Harness, enclosure, or kit contents are not listed.
Origin is assumed from export paperwork.
Supplier code is only six digits or from another market.
Current USTR Section 301 treatment has not been checked for the candidate line.
Exclusion claims have no source date.

These gaps can move the file between electronic assembly, machine part, power supply part, control module, sensor module, or service kit paths.

HTS candidate notes

Build candidate rows around the imported PCBA: controller board, power board, LED driver board, sensor interface board, radio board, or PCBA service kit. Each row should cite function, components, programming, set contents, origin, and supplier code.

Rejected paths should stay visible. If it is not a complete machine, say why. If cables are included, list them.

authority sources

Use USITC HTS for tariff text. Use CBP CROSS for PCB assemblies, electronic modules, controller boards, power boards, and service kits. Use USTR for the current Section 301 check.

planning path

Start with a table for board function, populated parts, programming, intended device, kit contents, origin, supplier code, and value. Then compare the candidate line with current Section 301 material.

The result should support broker review, not replace it.

Ask engineering for the plain-language job of the board. "PCB assembly" on its own is too thin when the same factory ships power boards, radio boards, and sensor boards.

questions importers ask

Does the board function matter?

Yes. Function and intended host device shape the review.

Does firmware matter?

Yes. Programmed status belongs in the evidence file.

planning boundary

This PCB assembly Section 301 page is a planning artifact. It is not an Entry Use classification, not a binding ruling, and not a legal opinion. The importer remains responsible for reasonable care and must obtain broker or customs authority review before filing.
