About Karuson International Co., Ltd. - Agriculture Supplier in China

Karuson International Co., Ltd. is based in China and lists six active products. The catalogue concentrates on eye‑protective equipment, specifically polarized PC+metallic sunglasses with TAC lenses, acetate sunglasses with TAC lenses, TPU ski goggles, polarized sports sunglasses with TAC/PC lenses, IPL laser protective goggles, and swimming goggles without dioptre correction. The items fall under the platform’s agriculture top‑category label, but the actual goods belong to the optical‑protective‑equipment segment. The supplier’s HS‑code families align with chapter 90 for optical instruments, such as 9004 for spectacles and 9005 for protective goggles.

All six entries specify material components like polycarbonate frames, metalised coating, acetate frames, TPU shells and TAC (tri‑acetate) lenses. While the listings omit detailed dimensions or power ratings, the product types imply industry‑standard features such as UV‑400 filtration for sunglasses and ANSI‑Z87.1 impact resistance for goggles. The platform records the supplier’s trust tier as "harbor," indicating a mid‑level verification status.

Product Range and Specialties of Karuson International Co., Ltd.

The product range includes two styles of sunglasses (polarized PC+metallic and acetate frames) equipped with TAC lenses, a sports‑oriented polarized sunglasses line with combined TAC/PC lenses, and three types of protective goggles (ski, IPL laser and swimming). In the eyewear market, polarized lenses are typically graded by visible light transmission (VLT) between 10‑30%, and TAC lenses are evaluated for UV‑400 blockage and anti‑glare performance. Acetate frames are usually classified by cellulose‑acetate content (typically 70‑80%). TPU ski goggles are commonly tested for fog resistance, impact energy absorption (often 200 J per ISO 12312‑1), and anti‑scratch coating. Laser protective goggles are specified by optical density (OD 3‑5) at the laser wavelength, while swimming goggles are measured by silicone seal hardness and optical clarity (≥90%).

Trade and Export Information - Karuson International Co., Ltd.

China is one of the world’s largest exporters of optical protective equipment, shipping most of its output to Europe, North America, the Middle East and Southeast Asia. Export shipments of sunglasses and goggles are recorded under HS chapter 90, primarily codes 9004 (spectacles, frames and parts) and 9005 (protective eyewear). Buyers typically require CE marking for the European market, ANSI compliance for the United States, and ISO 9001 quality‑management certification from Chinese manufacturers. Standard export packaging includes individual cardboard boxes or poly‑bag sealed units placed in 20‑ft or 40‑ft containers, with CIF or FOB terms negotiated per buyer preference. Chinese exporters often provide pre‑shipment inspection reports (e.g., SGS, Bureau Veritas) to satisfy import regulator requirements.

Sourcing from Karuson International Co., Ltd. - Buyer Guidance

When sourcing from Karuson International, buyers should request product test reports that confirm UV‑400 protection, impact resistance (ISO 12312‑1) and, for laser goggles, optical density at the relevant wavelength. CE conformity declarations and ISO 9001 certificates are typical documents to verify before finalising a contract. Samples of each model - polarized sunglasses, acetate sunglasses, ski goggles and laser goggles - allow verification of lens tint, frame fit and seal integrity. Standard minimum order quantities in the sector range from 300 to 1,000 units per style, and lead times of 30‑45 days are common for bulk production after sample approval. Packaging specifications usually require each unit to be boxed individually with protective film, suitable for container loading without damage.

What material is used for the frames of the polarized sunglasses?

The frames are described as polycarbonate (PC) with a metalised coating, a combination that provides lightweight strength and corrosion resistance.

Which lens technology is applied to the acetate sunglasses?

The acetate sunglasses are equipped with TAC (tri‑acetate) lenses, which offer anti‑glare and UV‑400 protection.

What standards should the ski goggles meet for international buyers?

Ski goggles made of TPU are typically required to comply with ISO 12312‑1 for impact resistance and to have anti‑fog and anti‑scratch coatings.

How is laser protection measured for the IPL laser goggles?

Laser protective goggles are evaluated by optical density (OD) at the laser’s wavelength, with OD 3‑5 being common for industrial laser safety.

Are swimming goggles supplied with any dioptre correction?

The listed swimming goggles are supplied without dioptre correction, suitable for general recreational use.

What documentation should a buyer request before placing an order?

Buyers should ask for CE conformity certificates, ISO 9001 quality‑management certificates, and test reports covering UV transmission, impact resistance and, where applicable, optical density.

What are typical packaging and shipping methods for these eyewear products?

Each unit is usually packed in an individual cardboard box or sealed poly‑bag, and shipments are loaded into 20‑ft or 40‑ft containers under CIF or FOB terms.

What is the usual lead time for a bulk order of the polarized sports sunglasses?

Lead times for bulk production of polarized sports sunglasses generally range from 30 to 45 days after sample approval and order confirmation.
