Olimex Ltd has temporarily suspended shipments to the USA due to new regulations requiring the collection of taxes and tariffs in advance. The company is unable to comply with the regulations, which demand a Certificate of Analysis to determine the exact amount of steel, copper, and aluminum in products. This has created chaos, with parcels being held in customs for weeks and importers facing unreasonable requirements. As a result, Olimex is advising US customers to purchase their products through Mouser or Digi-Key.
