Brexit Tariffs

CST Global will experience no changes to its import or export tariffs, irrespective of whether the Brexit outcome is a “Withdrawal Agreement”, “No-Deal”, or “No Brexit.”

The laser-based products which CST Global produce are categorized by the Harmonised Commodity Code (HCC) 85 41401000. The wafer-based products, used to make the lasers, are categorized as HCC 3818 0090 00. Both codes are zero percentage rated for imports from and exports to the EU, US, Israel and Hong Kong, from a ‘Third Country’, which the UK will become after Brexit. When CST Global exports to the Peoples Republic of China (PRC), existing tariffs will remain. These are paid by CST Global customers to the Chinese government.

The UK government has stated that in the event of a “No-Deal” Brexit, current tariffs will remain for at least twelve months. Should any new tariff structures be applied after twelve months, we will communicate them as soon as we are aware.

Summary

CST Global's lasers and wafers are categorised by the following HCC codes:

  • HCC 8541 4010 00 - Light-emitting diodes (LED) including laser diodes.
  • HCC 3818 0090 - Chemical elements doped for use in electronics, in the form of discs, wafers or similar forms.

Tariffs are zero percent rated (0%) for CST Global when importing from and exporting to the EU, US, Israel and Hong Kong. When CST Global exports to the PRC, existing tariffs will remain. These are paid by CST Global customers to the Chinese government.
