But then why are CBP (via the shippers) demanding a certificate of analysis rather than just referring people to the HTS? I know a lot of people in the synthesizer industry, and where previously they would just refer to the HTS classification for musical instruments there's a lot confusion about the recently announced 100% tariff on foreign made semiconductors. Since virtually every synth uses semiconductors and a great deal of the trade is in boutique products with relatively low manufacturing volumes, the uncertainty is creating major headaches on top of the headaches caused by the shipping puases.
