Tariff between US and China is effective now, so products with COO CN/US maybe charged a heavy tariff.
Please kindly note that our Incoterms are EXW, FCA and CPT, so customers are responsible for paying all sales tax, VAT, customs duty, and customs charges.
Chip One Stop does not know the exact amount since the tariff will be charged by the courier.
 
The HS code and COO is stated on our website. Should you have anything unclear, please do not hesitate to contact us before ordering.
