About Harvey Auto Parts Industry Company Limited - Automobile Spare Parts & Supplies Supplier in China

Harvey Auto Parts Industry Company Limited is based in China and lists five active products in its catalogue. The company focuses on automobile spare parts and supplies, covering components such as valves, servos and brake chambers. The catalogue includes items classified under HS Chapter 84 (e.g., 8481.20 for the Hv-u01 Unloader Valve and 8708.93 for the Clutch Servo). Materials range from carbon‑steel bodies with brass or steel internal parts to high‑grade cast iron housings, hardened steel pistons and EPDM‑sealed brass bodies. Each product description specifies the primary material composition and relevant HS code.

The five listed items are: Hv-u01 Unloader Valve (HS 8481.20, carbon steel body with brass/steel components), Clutch Servo (HS 8708.93, cast iron housing, hardened steel piston, reinforced rubber seals), Air Drier Cartridge (HS 8708.99, desiccant media in steel housing), Hv-s01 T30/30dd Brake Chamber (HS 8708.39, steel housing with rubber diaphragm and spring), and Hv-q01 Qr-1 Quick Release Valve (HS 8708.99, brass body with steel fittings and EPDM seals). The catalogue reflects a focus on hydraulic and pneumatic subsystems used in passenger and commercial vehicles. No additional company history or certifications are disclosed in the provided data.

Product Range and Specialties of Harvey Auto Parts Industry Company Limited

The product range covers hydraulic control valves and pneumatic components commonly used in brake, clutch and air‑suspension systems. Unloader valves such as the Hv‑u01 are typically rated for pressure ranges of 0.5 - 1.5 MPa and require corrosion‑resistant carbon steel (often meeting ASTM A36) with brass internal parts conforming to ASTM B16. Clutch servos generally employ cast iron housings (ASTM A536) and hardened steel pistons (Rockwell 45 - 55 HRC) to withstand cyclic loads, while reinforced rubber seals are usually NBR or EPDM meeting ISO 4649 hardness specifications. Air‑dryer cartridges incorporate silica‑gel or molecular‑sieve desiccants inside steel housings, with moisture‑adsorption capacities expressed in %RH reduction. Brake chambers like the Hv‑s01 T30/30dd are built with steel housings, rubber diaphragms (often EPDM) and calibrated springs, meeting ISO 2631 vibration standards. Quick‑release valves combine brass bodies (Cu‑Zn alloy conforming to BS 5152) with steel fittings and EPDM seals, typically designed for flow rates of 10 - 30 L/min at 0.7 MPa.

Trade and Export Information - Harvey Auto Parts Industry Company Limited

China is a major exporter of automotive spare parts, with HS Chapter 84 and 87 products shipping to Europe, North America, the Middle East and Southeast Asian markets. Buyers of hydraulic and pneumatic components usually require compliance with ISO 9001 quality management and, for automotive OEM supply chains, IATF 16949 certification. Additional certifications such as CE marking, RoHS and REACH are frequently requested for parts destined for the European Union. Shipping is commonly arranged in 20‑ft or 40‑ft containers, with each valve or servo packed in individual wooden crates or reinforced cardboard to protect against impact. Common Incoterms include FOB Shanghai or CIF Hong Kong, and customs documentation must reference the precise HS codes (e.g., 8481.20 for unloader valves, 8708.93 for servos) to avoid classification delays.

Sourcing from Harvey Auto Parts Industry Company Limited - Buyer Guidance

Potential buyers should request material test certificates confirming carbon‑steel composition, brass alloy standards and rubber hardness for each component. Functional test reports showing pressure‑hold performance, flow‑rate validation for valves and leak‑test results for brake chambers are standard verification steps. Because the catalogue does not list specific certifications, buyers are advised to ask the supplier to provide ISO 9001 or IATF 16949 audit reports before placing bulk orders. Typical minimum order quantities for specialized hydraulic valves range from 1 to 10 units, with lead times of 4 - 6 weeks after sample approval. Packaging specifications usually require each unit to be wrapped in anti‑corrosion film and placed in a sturdy crate, with palletization for container loading.

What types of automotive components does Harvey Auto Parts list in its catalogue?

The catalogue includes five hydraulic and pneumatic components: the Hv‑u01 Unloader Valve (HS 8481.20), Clutch Servo (HS 8708.93), Air Drier Cartridge (HS 8708.99), Hv‑s01 T30/30dd Brake Chamber (HS 8708.39) and Hv‑q01 Qr‑1 Quick Release Valve (HS 8708.99).

Which materials are used in the supplier’s unloader valve and quick‑release valve?

The Hv‑u01 Unloader Valve uses a carbon‑steel body with brass or steel internal components, while the Hv‑q01 Quick Release Valve features a brass body, steel fittings and EPDM seals.

What HS codes apply to the listed products?

The applicable HS codes are 8481.20 for the Unloader Valve, 8708.93 for the Clutch Servo, 8708.99 for both the Air Drier Cartridge and Quick Release Valve, and 8708.39 for the Brake Chamber.

Which industry standards are typically relevant for these hydraulic components?

Buyers usually reference ASTM A36 for carbon steel, ASTM B16 for brass fittings, ISO 2631 for brake‑system vibration, and EPDM seal hardness per ISO 4649. Pressure‑rating tests are commonly performed according to ISO 1219.

What documentation should a buyer request before ordering?

Request material test certificates, pressure‑hold and flow‑rate test reports, and any available ISO 9001 or IATF 16949 audit reports. For EU shipments, CE declaration and RoHS compliance documents are also advisable.

What are typical packaging and shipping methods for these parts?

Each valve or chamber is normally wrapped in anti‑corrosion film, placed in a reinforced wooden crate or heavy‑duty cardboard, and palletized for container loading. Export shipments often use FOB Shanghai or CIF Hong Kong terms with 20‑ft or 40‑ft containers.

What are common lead times and minimum order quantities for these items?

Lead times are generally 4 - 6 weeks after sample approval, and minimum order quantities range from one unit for prototype testing up to ten units for standard production runs.
