HTS and origin review for titanium, Inconel, superalloys, specialty stainless, optical glass, bearings, valves, gears, and AS9100 supply chains — with Section 232, AD/CVD, DFARS, and specialty-metals documentation handled before a shipment becomes a margin event.
Book a Free ConsultationAerospace and space manufacturers face customs exposure where material classification, country of origin, and contract documentation meet. Titanium, nickel alloys, specialty steel, optics, bearings, valves, and gear assemblies can trigger Section 232, AD/CVD, origin, and DFARS-specialty-metal questions. A broker should map the material flow, not just clear the entry.
Greenwich Mercantile starts with the actual import pattern — bill of lading, entry history, supplier lanes, HTS headings, origin, value, and filing behavior — then turns that evidence into a broker-ready customs workflow.
Titanium, Inconel, specialty steel, and optical inputs are expensive. If the HTS classification or origin basis is wrong across recurring entries, the back-duty exposure becomes material quickly.
When a production contract assumes a landed-cost model, a Section 232, AD/CVD, or origin correction hits gross margin directly. The customs file has to be audit-ready before the prime or CBP asks.
AS9100 shops often need origin, specialty-metals, and procurement evidence for customers. Routine entry filing does not create a DFARS/Berry-ready documentation packet.
Production ramps move faster than traditional broker review cycles. Greenwich keeps broker filings aligned with procurement, quality, and materials management.
Classification review for 8108 titanium, 7505/7506 nickel alloys, specialty steel, bearings, valves, gear assemblies, optical glass, ceramics, and precision housings.
We screen recurring material inputs for Section 232 exposure and active AD/CVD orders, then flag high-risk origin or supplier changes before they create deposit surprises.
Origin files for wrought, powder, scrap, semi-finished, and machined inputs — tied back to purchase orders, mill certs, and supplier evidence.
We organize the customs-side evidence quality teams need for specialty-metal flow-downs while routing legal determinations to counsel where required.
Greenwich can work beside the existing broker and outside counsel, translating material data into entry-ready and audit-ready customs documentation.
When historical entries are wrong, we prepare the customs file for Post-Summary Corrections and protests when the law and facts support recovery or correction.
Common chapters include 8108 for titanium, 7505 and 7506 for nickel alloys, 7218/7222/7228 for specialty steel, 8481 for valves, 8482 for bearings, 8483 for gears and shafts, 9001 for optical elements, and 7002 for glass inputs.
Greenwich handles the customs-side evidence layer — origin records, supplier documentation, HTS review, entry support, and broker coordination. Contract-law or final DFARS legal interpretations should stay with counsel; we prepare the records counsel and customers need.
No. Aerospace shops often have conservative broker relationships. Greenwich can start as a materials-flow audit, recurring compliance review, PSC/protest support desk, or broker coordination layer before any filing change.
We start with recent bills of lading, entry summaries, supplier lanes, and material families. The goal is one defensible finding: a classification risk, origin support gap, Section 232/AD/CVD issue, or recoverable duty opportunity.
