US Tariffs and Import Duties on CNC Machined Parts from India: Complete 2026 Guide

Written by the export logistics team at Robocon CNC Pvt Ltd, Pune, India — shipping CNC machined parts to USA customers since 2005.

One of the first questions US procurement teams ask when considering Indian CNC suppliers: what are the import duties and tariffs on CNC machined parts coming from India?

The good news: most precision CNC machined metal parts imported from India to the USA attract 0% import duty. India is also not subject to the Section 301 China tariffs (25%), making Indian-sourced parts significantly more cost-competitive than China-sourced equivalents.

HS Code Classification for CNC Machined Parts

US Customs and Border Protection (CBP) classifies imports using the Harmonized Tariff Schedule (HTS). Most CNC machined metal parts fall under these chapters:

• Chapter 84: Machinery and mechanical appliances — covers most CNC machined components, housings, brackets, fittings, and precision mechanical parts. Many subheadings carry 0% duty.
• Chapter 73: Articles of iron or steel — covers steel CNC machined parts, fasteners, and structural components. Generally 0% duty for precision machined articles.
• Chapter 76: Articles of aluminium — covers aluminum CNC machined parts. 0% for most finished machined articles.
• Chapter 72-71: Copper, brass, and precious metals — varies by specific alloy and part type.

The exact HTS code depends on the finished part geometry and material, not the raw material form. A CNC machined aluminum bracket is classified differently than raw aluminum bar stock. Your customs broker should classify based on the finished article characteristics.

Section 301 China Tariffs: India's Advantage

Since 2018, the US has imposed Section 301 tariffs of 25% on most goods imported from China. As of 2026, these tariffs remain in effect and apply to CNC machined parts from Chinese suppliers.

India is NOT subject to Section 301 tariffs. This means:

• A $15 CNC machined bracket from China costs $18.75 after the 25% tariff
• The same bracket from India costs $15 (no tariff)
• India's effective cost advantage is 20–25% on top of the base machining cost savings
• This makes India more cost-competitive than China for most precision CNC parts in 2026

What Documentation Does US Customs Require?

Robocon CNC handles all export documentation from Pune. For each shipment to the USA, we provide:

• Commercial Invoice: Itemized list with part numbers, quantities, unit values, and total declared value in USD
• Packing List: Detailed packing list with gross/net weight, dimensions, and package count
• HS Code Classification: Correct HTS code for each line item based on finished part classification
• Certificate of Origin: Documented proof of Indian manufacture (required for some trade agreements)
• EEI Filing (AES): Electronic Export Information filing for shipments exceeding $2,500 declared value
• Material Test Certificates: EN 10204 3.1 certificates traceable to material heat numbers

Most US customs brokers report same-day clearance for CNC machined parts from India when documentation is complete and HS codes are correctly classified.

What Duties Apply to Specific Part Types?

Based on Robocon CNC's experience shipping to US customers across 15+ years:

• Aluminum CNC machined parts (6061, 7075): 0% duty under HTS 8466/7616 subheadings
• Stainless steel CNC parts (304, 316L): 0% duty under HTS 8466/7307 subheadings
• Titanium CNC parts: 0% duty under most HTS 8466 subheadings
• Brass/copper CNC parts: 0–2.5% depending on specific HTS classification
• PEEK/plastic CNC parts: 0–3.4% depending on polymer type and HTS subheading

Important: These are general classifications. Always confirm with your customs broker for your specific part numbers and HTS codes. Rates can vary by subheading and may change with new trade legislation.
