Please check with Customs for updated information. Products of the above-listed column 2 countries are dutiable at the column 2 rates of duty, even if purchased in or sent from another country. A crystal vase made in Laos and purchased in Switzerland would be dutiable at the column 2 rate. If the article accompanies you, however, it may be entered under your duty-free personal exemption or the flat rate of duty allowance. The above is excerpted from the US Customs web page which you can access direct, for further information.
Costs vary depending on the port of entry.
Such service charges would be for your account if you choose not to clear your goods direct. Read instructions and download the 3299 form here. Read and print-out the Treasury Supplemental form. The above constitutes general advice only. Sefco-Export is not a US Customs broker.
