Sine's global footprint — with operational branches in Shenzhen, China and Mumbai, India — positions the company as a natural partner for importers and freight forwarders managing supply chains from Asia. Their particular expertise in China-origin shipments makes them a go-to resource for importers navigating complex HTS code classification, 10-digit tariff code determination, and accurate duty assessment on goods ranging from consumer electronics to machinery and equipment.
For importers who need end-to-end port handling, Sine manages the full destination cycle: customs entry preparation, ISF 10+2 filing (importer security filing), document submission, port drayage coordination, and empty container return tracking. Their proprietary software platform generates instant quotes around the clock, eliminating the back-and-forth that typically delays cargo release and inflates costs. Partners report saving up to $115 per container on trucking and cutting up to 80% of time spent chasing unresponsive agents.
Sine also handles importer of record requirements, assists with continuous customs bond and single entry bond customs arrangements, and can guide clients through Type 86 entry customs procedures for low-value Section 321 de minimis shipments. Importers exploring duty drawback programs — including manufacturing drawback and unused merchandise drawback — can consult with Sine's team on eligibility and documentation requirements.
As a one-stop customs and logistics partner, Sine eliminates the need to juggle multiple local agents at destination ports. Their documented expertise in importing eBikes and similar electronics from China reflects a broader capability in advising clients on import bond requirements, tariff code classification, and cost-effective customs strategies.
