About Zhuzhou Uko Precision Carbide Co., Ltd. - Tungsten Products Supplier in China

Zhuzhou Uko Precision Carbide Co., Ltd. is located in China and lists 13 active products across tungsten carbide components, dies, nail tools and related equipment. The catalogue includes items such as Tungsten Carbide Wire Guides, Rolls, Wire Drawing Dies, Nail Cutter Dies and various roller types, each linked to HS‑code families 8101, 8207, 8455 and 8103. Materials are identified as cemented carbide (WC‑Co) with grades ranging from YG8 to YG20, and some items combine tool steel (HSS/D2) with carbide. The supplier’s top categories are recorded as Tungsten Products, Dies & Mouldings, Nails, Agriculture and Cosmetics & Beauty Parlour Equipments. The product list reflects a focus on precision components used in wire production, mesh welding and nail manufacturing processes.

The listed products cover both standard and specialized forms, for example the Tungsten Carbide Guide Roller (HS 8103.20) uses a 94 % WC / 6 % Co composition (YG8 grade) while the Tungsten Carbide Roller (HS 8455.30) is offered in YG15/YG20 grades. Several die items share the HS code 8207.20, indicating classification under “tools for working metal; steel cutting shears, blades and similar”. The presence of cold rolls, hot rolls and descaling rollers shows capability for both high‑temperature and abrasive applications. No certifications are explicitly listed for the supplier, so buyers should verify conformity to industry standards such as ISO 9001 or specific carbide grade certifications where required.

Product Range and Specialties of Zhuzhou Uko Precision Carbide Co., Ltd.

The catalogue comprises a mix of wire guides, rollers, dies and nail cutting tools, each produced from tungsten carbide composites. Typical industry grades for WC‑Co range from YG8 (≈ 8 % cobalt) to YG20 (≈ 20 % cobalt), with higher cobalt content providing greater toughness for heavy‑duty die applications. In the wire‑drawing sector, standard specifications include hardness values of 1 800 - 2 200 HV and dimensional tolerances within ±0.02 mm for guide surfaces. Nail cutter dies often require a wear‑resistant surface finish of Ra ≤ 0.8 µm to maintain cutting precision over long runs. The cold and hot roll products are commonly supplied in 20‑ft or 40‑ft containers, packed in wooden crates with protective steel plates to prevent chipping of the carbide surfaces.

Trade and Export Information - Zhuzhou Uko Precision Carbide Co., Ltd.

China is a major exporter of tungsten carbide tooling, with primary markets in Europe, North America and Southeast Asia for metal‑working and wire‑drawing equipment. HS‑code 8207 series products are subject to customs inspections that verify material composition and may require a test certificate confirming cobalt content and hardness. Buyers frequently request ISO 9001 quality‑management certification and material test reports conforming to ASTM B604 for WC‑Co alloys. Shipping of heavy rolls and dies typically uses 40‑ft containers, with standard Incoterms such as FOB or CIF, and pallets are often wrapped in shrink film and secured with corner protectors. Export documentation from China usually includes a commercial invoice, packing list, certificate of origin and, for high‑value carbide items, a material safety data sheet (MSDS).

The supplier’s target markets are not specified, so sourcing parties should consider the usual import destinations for carbide tooling - automotive manufacturers in Germany, wire‑drawing plants in the United States, and construction equipment makers in Japan. Importers generally need to ensure compliance with local environmental regulations concerning cobalt handling, and may be required to submit a declaration of compliance with REACH or RoHS where applicable.

Sourcing from Zhuzhou Uko Precision Carbide Co., Ltd. - Buyer Guidance

When evaluating Zhuzhou Uko Precision Carbide Co., Ltd., request material test reports that detail WC percentage, cobalt binder content and measured hardness (HV). Verify that the supplied grades (YG8, YG15, YG20) match the performance requirements of your application, such as toughness for high‑speed wire drawing or wear resistance for nail cutting dies. Ask for a sample of the finished die or roller to assess surface finish and dimensional accuracy before placing a bulk order. Because no specific certifications are listed, confirm the supplier’s quality‑management system (e.g., ISO 9001) and ask for any third‑party inspection certificates that cover the shipped batch. Confirm packaging details - protective crates, wood pallets and moisture‑resistant wraps - to avoid damage during sea freight.

What HS codes are associated with the tungsten carbide rolls listed by the supplier?

The Tungsten Carbide Rolls are classified under HS code 8101.99, while cold rolls and other roller types use HS codes 8455.30 and 8455.90 respectively.

Which material grades are offered for the wire drawing dies?

The wire drawing dies are made from cemented carbide (WC‑Co) with typical grades ranging from YG8 to YG15, providing hardness between 1 800 and 2 200 HV.

Are certification documents such as ISO 9001 or material test reports available?

The supplier does not list specific certifications, so buyers should request ISO 9001 compliance certificates and ASTM B604 material test reports for each product batch.

What are the typical packaging methods for heavy carbide rollers?

Heavy rollers are usually packed in wooden crates with steel corner protectors, wrapped in shrink film and placed on standard Euro pallets for 20‑ft or 40‑ft container loading.

What minimum order quantities (MOQ) apply to the nail cutter dies?

The catalogue does not specify MOQ; buyers should ask the supplier directly, as MOQ for precision dies can range from a single custom set to several hundred pieces depending on size.

What lead time should a buyer expect for a custom tungsten carbide die?

Lead times for custom carbide dies generally range from 4 to 8 weeks, depending on the complexity of the geometry and the required grade of WC‑Co material.

Which regions most commonly import these tungsten carbide products from China?

Typical import regions include Europe (especially Germany and Italy), North America (United States and Canada) and East Asia (Japan and South Korea), where the products are used in automotive, wire‑drawing and construction equipment industries.

What regulatory tests are commonly required for tungsten carbide tools before customs clearance?

Customs authorities often request a material composition certificate, hardness test results (HV), and, where cobalt is present, a safety data sheet to verify compliance with environmental and health regulations such as REACH.
