Product Range and Specialties of Divel (Shanghai) Optical Trading Co., Ltd

Divel’s catalogue offers a spectrum of lenses that match typical industry classifications. The flat round blended top bifocal lenses and the progressive Aurora 4D freeform lens represent multifocal solutions commonly graded by add power and corridor width. Photochromic lenses such as the 1.56 Fotochroma SHMC are evaluated by activation speed, visible light transmission (VLT) and UV blocking, with standards often referencing ISO 12312‑1. High‑index options like the 1.74 Aspheric and 1.670 Aspheric single‑vision lenses provide reduced thickness for strong prescriptions, with typical Abbe values between 30 and 45. Standard single‑vision lenses listed (e.g., Cr39 1.499 UC NC and 1.499 Resin SHMC Silken) are usually made from CR‑39 or resin blends, offering a baseline refractive index of 1.49 and an Abbe value around 58. UV‑protective lenses such as the 1.610 Blue Natural Lens UV420 and Nouv UV400 protection are designed to block 400 nm and below, meeting the EU UV‑400 requirement. Semi‑finished resin lenses serve optical labs that apply final surfacing and coating in‑house. Industry specifications commonly reference ISO 14889 for optical performance, ANSI Z80.1 for material properties, and surface quality measured in scratch‑dial and gloss.

Trade and Export Information - Divel (Shanghai) Optical Trading Co., Ltd

China is a major exporter of spectacle lenses, with Shanghai serving as a logistics hub for container shipments. Optical lenses fall under HS Code 9001.10 (spectacle lenses, unmounted), which is routinely inspected for material compliance and labeling. Export shipments are typically packed in cardboard cartons or wooden crates, with moisture‑resistant liners to protect resin lenses during sea freight. Common Incoterms used by Chinese suppliers include FOB Shanghai and CIF major ports.

Importers in Europe, North America, and the Asia‑Pacific region frequently require CE marking, ISO 9001 quality management, and for the United States, FDA 510(k) clearance for medical‑grade lenses. Buyers also request test reports covering refractive index, Abbe value, UV transmission, and photochromic cycle performance. Chinese optical manufacturers often hold ISO 13485 for medical devices, though verification is needed per supplier. Documentation such as a material safety data sheet (MSDS) and a certificate of origin is standard for customs clearance.

Sourcing from Divel (Shanghai) Optical Trading Co., Ltd - Buyer Guidance

When sourcing lenses from Divel, buyers should obtain a detailed data sheet that lists refractive index, Abbe value, lens thickness range, UV cutoff, and any coating options. Requesting ISO 14889 optical performance test reports and, for photochromic products, activation/de‑activation cycle data will help confirm compliance with buyer specifications.

Verification of certifications is essential; ask for copies of the supplier’s ISO 9001 or ISO 13485 certificates, CE declaration for EU markets, and any FDA 510(k) documentation if the lenses are intended for the United States. Confirm minimum order quantities, typical lead times (often 20‑30 working days for bulk production), and packaging details such as lens protection films and carton dimensions before finalizing the order.

Which certifications should I verify for optical lenses sourced from China?

Buyers normally request ISO 9001 or ISO 13485 quality‑management certificates, CE marking for EU shipments, and FDA 510(k) clearance for lenses marketed as medical devices in the United States.

What typical minimum order quantity applies to high‑index or photochromic lenses?

Many Chinese lens manufacturers set MOQs between 5,000 and 10,000 pairs per index grade, but the exact figure should be confirmed with Divel for each product line.

What sample options are available before placing a bulk order?

Divel can provide single‑vision or progressive lens blanks for evaluation, usually shipped in protective sleeves; request a sample kit specifying the desired index and coating.

Which HS code is used for the lenses listed in Divel’s catalogue?

The standard HS classification for unmounted spectacle lenses is 9001.10, which applies to the products described in the catalogue.

What packaging and shipping terms are commonly used for these lenses?

Lenses are packed in moisture‑resistant cartons with individual lens protectors, and shipments are often quoted on FOB Shanghai or CIF to the buyer’s destination port.

How can I verify the UV protection performance of the 1.610 Blue Natural Lens UV420?

Request the supplier’s UV transmission test report showing cutoff at 400 nm or lower and compliance with the EU UV‑400 standard; the report should include measured % UV blockage.
