Compliance is critical to avoid customs seizures. For the US market, ensure products are FCC certified and meet Energy Star ratings. For the EU, CE marking and RoHS compliance (Restriction of Hazardous Substances) are mandatory. Additionally, verify the CB Scheme certification, which facilitates international acceptance of test reports. If you are sourcing for specific regions, check for local digital tuner compatibility (e.g., DVB-T2 for Europe/Asia, ATSC 3.0 for North America, or ISDB-T for Latin America).
