Customs tariff exemptions updated to add mobile phone components, revise classifications, and restructure duty treatment. Amendments to the customs exemption schedule insert distinct entries for vibrator motors/ringers, display assemblies, touch panels and related inputs for use in manufacture of cellular mobile phones, modify and omit specified items and classifications (including adding fingerprint reader/scanner and redefining All goods other than charger or power adapter), substitute the scope of certain tariff headings to exclude microphone and receiver parts, and add transitional and sectoral PCBA entries for mobile and telecommunications equipment, thereby restructuring duty treatment and exemptions.
