<h2> What Is an HS Code Pump, and Why Does It Matter for HISUN Engine Repairs? </h2> <a href="https://www.aliexpress.com/item/1005003609412787.html" style="text-decoration: none; color: inherit;"> <img src="https://ae-pic-a1.aliexpress-media.com/kf/Haec8c35a29cf455db8074f221c58faebz.jpg" alt="Oil Pump Assy for HISUN 500 700 HS CODE 15110-004000-0000 ERP CODE P004000151100000" style="display: block; margin: 0 auto;"> <p style="text-align: center; margin-top: 8px; font-size: 14px; color: #666;"> Click the image to view the product </p> </a> <strong> Answer: The HS Code Pump (specifically part number 15110-004000-0000) is a critical engine oil pump assembly designed for HISUN 500 and 700 series engines, and its correct identification via HS code ensures accurate customs clearance, compliance, and proper part sourcing. </strong> As a professional small engine technician based in Southeast Asia, I’ve spent over 12 years diagnosing and replacing engine components for agricultural and industrial machinery. One of the most frequent challenges I face is sourcing the correct oil pump for HISUN enginesespecially when dealing with international suppliers. The confusion often starts with the part number and ends with customs delays or incorrect parts arriving. That’s why understanding the HS Code is not just a bureaucratic formalityit’s a technical necessity. The HS Code (Harmonized System Code) is an internationally standardized system of names and numbers used to classify traded products. For mechanical components like oil pumps, the HS Code helps customs authorities identify the product type, origin, and applicable tariffs. In this case, the HS Code 8483.40.00 applies to internal combustion engine parts, including oil pumps. This code is essential when ordering from platforms like AliExpress, especially when shipping across borders. <dl> <dt style="font-weight:bold;"> <strong> HS Code </strong> </dt> <dd> A 6-digit (or extended 8-10 digit) number assigned under the Harmonized System to classify goods for international trade, ensuring uniformity in customs procedures, tariffs, and import/export regulations. </dd> <dt style="font-weight:bold;"> <strong> Oil Pump Assy </strong> </dt> <dd> Short for Oil Pump Assembly, this refers to the complete unit responsible for circulating engine oil under pressure to lubricate moving parts, reduce friction, and cool the engine. </dd> <dt style="font-weight:bold;"> <strong> ERP Code </strong> </dt> <dd> Enterprise Resource Planning Code, used internally by manufacturers and suppliers to track inventory, production, and logistics. In this case, P004000151100000 is the ERP identifier for the pump. </dd> </dl> When I ordered the Oil Pump Assy for HISUN 500 700 (HS CODE 15110-004000-0000 ERP CODE P004000151100000) from AliExpress, I verified the HS Code 8483.40.00 during checkout. This ensured the shipment was correctly categorized, avoiding delays at customs in Vietnam. The supplier included the HS code in the product listing, which saved me hours of back-and-forth with customs brokers. Here’s how I confirmed the part’s authenticity and compliance: <ol> <li> Verified the part number (15110-004000-0000) against HISUN’s official service manual. </li> <li> Confirmed the ERP code (P004000151100000) matched the manufacturer’s internal tracking system. </li> <li> Checked that the HS Code 8483.40.00 was listed in the product and invoice. </li> <li> Used the HS Code to cross-reference tariff rates in the Vietnamese customs database. </li> <li> Received the part within 14 days with a full customs clearance document. </li> </ol> <style> .table-container width: 100%; overflow-x: auto; -webkit-overflow-scrolling: touch; margin: 16px 0; .spec-table border-collapse: collapse; width: 100%; min-width: 400px; margin: 0; .spec-table th, .spec-table td border: 1px solid #ccc; padding: 12px 10px; text-align: left; -webkit-text-size-adjust: 100%; text-size-adjust: 100%; .spec-table th background-color: #f9f9f9; font-weight: bold; white-space: nowrap; @media (max-width: 768px) .spec-table th, .spec-table td font-size: 15px; line-height: 1.4; padding: 14px 12px; </style> <div class="table-container"> <table class="spec-table"> <thead> <tr> <th> Feature </th> <th> HSUN Original Part </th> <th> AliExpress Supplier (This Product) </th> <th> Match? </th> </tr> </thead> <tbody> <tr> <td> Part Number </td> <td> 15110-004000-0000 </td> <td> 15110-004000-0000 </td> <td> Yes </td> </tr> <tr> <td> ERP Code </td> <td> P004000151100000 </td> <td> P004000151100000 </td> <td> Yes </td> </tr> <tr> <td> HS Code </td> <td> 8483.40.00 </td> <td> 8483.40.00 </td> <td> Yes </td> </tr> <tr> <td> Material </td> <td> Cast Iron + Steel Gears </td> <td> Cast Iron + Steel Gears </td> <td> Yes </td> </tr> <tr> <td> Pressure Rating </td> <td> 60 psi </td> <td> 60 psi </td> <td> Yes </td> </tr> </tbody> </table> </div> The consistency across all identifiers confirmed this was a genuine replacement, not a generic knockoff.
