Surat has one wrinkle worth knowing. The customs list of connected sites includes an air cargo station at the Surat Diamond Bourse (CBIC / ICEGATE list, Feb 2024 (opens in a new tab)), yet Surat airport moved no international freight in the year. So paperwork may start in Surat while the goods still fly from Mumbai. Check this with your forwarder if you buy jewellery there.
What Does That Mean for Samples?
Samples usually go by express courier, not air cargo, and the same geography applies. The parcel still has to reach a gateway with international flights. Ask your supplier one question before you count the days: "Which city does it leave India from?" If the answer is a truck ride away, add that.
Two more things catch buyers out, by their own accounts on forums. First, when the supplier ships on its own courier account, the courier often ends up as the importer of record, which matters if you ever want duty back (r/ecommerce, 2026 (opens in a new tab)). Second, couriers sometimes classify goods wrongly, and one US distributor said the wrong tariffs "are starting to add up" (r/smallbusiness, 2025 (opens in a new tab)). For a one-off sample, fine. For regular stock, use your own account or your own forwarder. Our freight forwarder guide covers when that's worth it.
When Is Air Worth It Over Sea?
For small lots, more often than people think. Forwarders on a UK small-business forum use about 200 kg as the point where air and sea cost roughly the same on India shipments, and below it sea saves little and takes six to eight weeks (r/smallbusinessuk, 2024 (opens in a new tab)). Another forwarder notes that for small air shipments an express courier often beats a forwarder, because forwarders' minimum charges bite (r/logistics, 2025 (opens in a new tab)). Those are practitioner rules of thumb, not published rates, so get both quotes for your own lot.
