About Shenzhen Dy Optical Manufactory - Fashion Accessories Supplier in China

Shenzhen Dy Optical Manufactory is based in China and lists five active products in its catalogue. The company focuses on fashion accessories, specifically optical frames for spectacles. Its product lineup includes a manganese glasses frame, a titanium optical frame, a stainless steel optical frame, a nickel‑silver optical frame and a memory‑metal (Memroy) optical frame. Each item is classified under the general HS chapter for frames (HS 9004). The catalogue does not specify additional product attributes beyond material composition.

The five frame types cover a range of alloy and metal constructions commonly used in eyewear manufacturing. The manganese frame represents a lightweight alloy option, while titanium offers high strength‑to‑weight ratio and corrosion resistance. Stainless steel frames provide durability and cost efficiency, nickel‑silver frames are valued for aesthetic appeal, and memory‑metal frames are designed for flexibility and shape retention. No further details on dimensions, finishes, or certifications are provided in the supplier data.

Product Range and Specialties of Shenzhen Dy Optical Manufactory

The catalogue’s five metal frames correspond to standard industry grades: titanium frames are typically made from Grade 5 (Ti‑6Al‑4V), stainless steel frames use 304 or 316 stainless, nickel‑silver frames contain roughly 12 % nickel, 60 % copper and 28 % zinc, manganese alloy frames are lightweight manganese‑based alloys, and memory‑metal frames are NiTi shape‑memory alloys. Buyers usually evaluate frame thickness (1.5‑2.5 mm), overall weight (15‑30 g per pair), hinge type (spring or screw), and surface finish (polished or brushed) against ISO 12870 specifications for eyewear frames.

Typical specifications for metal eyewear include tensile strength above 400 MPa for titanium, corrosion resistance in saline environments, and lead‑free composition to meet REACH and RoHS limits. Colour options often range from natural metal tones to black‑oxide or gunmetal finishes, and optional coating processes such as PVD are common in the sector.

Trade and Export Information - Shenzhen Dy Optical Manufactory

China is one of the world’s largest exporters of metal eyewear frames, with the United States, European Union, Japan and Southeast Asian countries representing the bulk of demand. Frames are generally declared under HS code 9004.10 (metal spectacles frames) and are subject to customs checks for material safety, lead content and compliance with regional standards such as CE for the EU or FDA 21 CFR 820 for the United States.

Importers typically require certifications like ISO 9001 for quality management, ISO 14001 for environmental compliance, and third‑party inspection reports (e.g., SGS, Bureau Veritas). Shipping is commonly performed in 20‑ft containers holding several thousand frames, using FOB Shanghai or CIF terms to major ports. Export documentation includes a commercial invoice, packing list, certificate of origin and the appropriate HS code declaration.

Sourcing from Shenzhen Dy Optical Manufactory - Buyer Guidance

Buyers should request a material test report or certificate of analysis for each frame type to verify alloy composition and confirm compliance with REACH or RoHS limits. Dimensional drawings, sample units, and tensile or corrosion test results help ensure the frames meet ISO 12870 and any market‑specific safety standards before bulk ordering.

Typical minimum order quantities for metal frames range from 500 to 1 000 pieces per style, with a production lead time of 30‑45 days after design approval. Third‑party pre‑shipment inspections and packaging verification (individual blister packs or foam inserts within cartons of 100‑200 units) are standard practices to reduce the risk of damage and facilitate customs clearance.

What types of optical frames does Shenzhen Dy Optical Manufactory offer?

The catalogue lists five metal frame types: a manganese alloy frame, a titanium frame, a stainless steel frame, a nickel‑silver frame and a memory‑metal (NiTi) frame. All are classified under the general HS heading for spectacles frames (HS 9004).

Are material composition certificates available for the frames?

Buyers should request a material test report or certificate of analysis that confirms the alloy percentages for each frame type. Such documents are standard for metal eyewear and help verify compliance with REACH or RoHS.

Which certifications are typically required for metal eyewear frames from China?

Importers usually ask for CE marking for EU markets, FDA registration for the United States, and ISO 12870 compliance for frame dimensions and safety. Third‑party inspection reports (e.g., SGS) are also commonly requested.

What are the usual minimum order quantities and lead times?

For metal frames, manufacturers often set a minimum order of 500 pieces per style, with a production lead time of 30‑45 days after design approval. Larger orders may benefit from economies of scale in packaging.

How are the frames packaged for export?

Frames are typically packed in individual protective blister packs or foam inserts, then placed in cartons of 100‑200 units. Full container loads (20‑ft) can contain several thousand frames, depending on packaging density.

Which markets commonly import Chinese metal eyewear frames?

Major destinations include the United States, European Union countries, Japan, South Korea and Southeast Asian markets. These regions source frames for both branded and private‑label eyewear manufacturers.

What HS code should be used for customs clearance of these frames?

Metal spectacles frames are generally classified under HS code 9004.10 (frames of metal, other than safety glasses). Importers should confirm the exact sub‑heading with customs authorities.
