VIETNAM QUARTZ JOINT STOCK, an exporter of natural quartz and slabs, has shown a modest but steady outbound flow primarily from Haiphong, Vietnam to key US Gulf and Atlantic entry points such as Charleston, SC and Miami, FL, averaging 25‑26 tonnes per shipment and roughly 1.5 TEU each. Over the past twelve months the firm completed four recorded shipments to three recurring buyers—US Coastal Granite Inc, Tradewide Trade LLC and The Stone Shop—consistently using HS Code 251622 (quartz stone) with occasional 710410 entries. For buyers, this pattern signals reliable access to high‑quality quartz slabs from a single Asian port, limited but dependable order volumes, and a stable partner base that can be scaled with larger contracts. For customs brokers, the company’s filings are straightforward: repeat HS codes, predictable routing, and consistent documentation across shipments, which supports efficient clearance and low risk of classification disputes.
