Robertshaw Inc, an importer focused on electronic components and related hardware, consistently sources from Chinese manufacturers such as Huizhou Glorysky, Ocean Controls, and Ningbo Yong You, concentrating on HS Codes 851190, 853890, 842611 and related categories. Over the past two years the firm averaged 1‑3 shipments per month, totaling roughly 12‑15 TEU and ≈ 30 tons, predominantly off‑loading at Los Angeles (2704) and Long Beach (2709) with occasional Houston entries. Suppliers can view Robertson Inc as a reliable, mid‑size US buyer with steady demand for relays, thermostats, capacitors and control boards, showing repeat orders and incremental growth in weight volumes. For customs brokers the import pattern is predictable: uniform HS‑code usage, limited port diversity, and consistent documentation across shipments, resulting in efficient clearance cycles and low variance in tariff classification. This stability supports streamlined customs processing while offering suppliers a clear, ongoing market for specialized electronic parts.
