I just entered the mechanicalforeign trade industry. The customer's drawing is marked with 'All sharp edges to be deburred' and 'Surface finish: Ra 1.6'. What do these two sentences specifically refer to? Will they affect customs declaration, freight, and price negotiations with the customer?

The two annotations you mentioned: the first requires all sharp edges to be deburred，and the second is surface roughness Ra 1.6 microns. From a compliance perspective，these are precision machined parts. When classifying HS codes，pay attention to whether "high precision" or "special process" regulatory conditions are involved. Technical specification descriptions must be attached during customs declaration，there is a high probability of customs inspection，especially for exports to the EU which may involve CE certification or anti-dumping investigations. Suggest preparing material component proofs and processing process descriptions in advance，and noting "precision machined parts" in the remarks column of the declaration form to avoid being misjudged as ordinary parts leading to rejection.

These two sentences have high requirements for logistics packaging. If deburring is not handled properly, sharp edges will pierce rust-proof bags, leading to easy rusting during sea transport; for Ra 1.6 surface precision, ordinary cardboard boxes + foam do not provide enough protection. Suggest using vacuum rust-proof bags + custom EVA lining + double-layer corrugated boxes. For

air freight, add "Fragile" and "Keep Dry" labels. When using sea freight LCL, be sure to note "KEEP DRY" on the B/L and choose a reputable forwarder to avoid rough handling at the destination port. If the cargo value is high, going by FCL is safer; though freight is more expensive, the risk of damage is low.
