NI60 Thread Insert Import Guide | Avoiding Material Adulteration & HS Code Classification Pitfalls
or complex compliance issues.
clearance and fund security.

You think it’s enough to be heat-resistant?Ninety percent of purchasing managers failed the material verification process for NI60 threaded inserts.In the aerospace and high-end mold manufacturing industries,NI60 (nickel-chromium alloy) steel wire threaded inserts have become a must-have due to their excellent high-temperature resistance and corrosion resistance.However,the reality is that many companies spend money on imported nickel-based alloys,only to receive products coated with nickel on the surface that are actually ordinary stainless steel products,or even worse,counterfeit products.The delay of the goods at the port was caused by an error in the HS code classification.This is not just a cost issue,but also a major safety hazard.
Why are NI60 threaded bushings so "delicate" when imported?
Unlike ordinary 304 stainless steel screw sleeves,NI60 belongs to special metal materials,and its import process involves strict material supervision and complex customs code classification.Many traders often adopt the "ambiguous declaration" strategy to save trouble or reduce tax fees,which leaves huge compliance risks for receiving enterprises.
We need to clarify the core differences first in order to gain the upper hand at the negotiation table:
| Comparison dimension | Normal stainless steel screw sleeves (304/316) | NI60 high-temperature nickel-based alloy screw sleeve | Purchasing and importing risk points |
|---|---|---|---|
| Main ingredients | Fe,Cr,Ni (8-10%) | Ni (≥60%),Cr,Fe | If the ingredient test fails,you will not be able to enjoy the original factory warranty. |
| Work temperature | 800°C (easily oxidized) | It can reach temperatures above 1150°C. | Under high temperatures,the strength of the screw decreases,leading to stripped threads. |
| The tendency of HS codes | 7318 (Steel plugs) | 7508 (nickel plug) or 7318 | Classification disputes: If declared as steel,it is suspected of tax evasion; if declared as nickel,a certificate of composition is required. |
| Supplier qualifications | Ordinary Fastener Factory | It is necessary to have the qualification for processing special alloys | There are a large number of "knockoff" counterfeit products on the market,without warranty certificates for the smelting furnace. |
Advanced agent selection and practical operation of importing SOP
Don’t just focus on the price.For special materials like NI60,you need to consider other factors as well."Compliance"and"Traceability"This is the core.The following is a proven standardized operation process:
Step 1: Technology locking and material pre-review Output:
Before contacting an agent,it’s essential to clarify the technical parameters first to prevent the agent from substituting inferior products for genuine ones.
- RequestaMaterialCertificate(MTC):RequiresupplierstoprovidematerialcertificatesinaccordancewithEN10204standard3.1or3.2,anditmustclearlyindicatethattheNicontentis≥60%.
- Definethebrandnamestandards:ConfirmwhethertoexecuteNASM8891,MS21235,ortheISOstandard.NI60typicallycorrespondstoInconel600orsimilarnickel-basedalloygrades.
Step 2: Review of the agent’s "invisible capabilities" Output:
A qualified NI60 threaded bushing agent should not just be a middleman,but should also serve as a technical consultant.

Insights from a senior consultant who is not an insider in the industry
After working in this industry for 15 years,I’ve seen too many cases where people fell into traps because they were eager to get a bargain.Here’s one such example.Melting Batch NumberWhen it comes to the details of purchasing,90% of procurement personnel tend to overlook them.
The real imported NI60 threaded bushings should have corresponding labels on each package and even on each box of products.Lot No.(Furnace No.)Moreover,this furnace number must be exactly the same as the one on the Material Certificate (MTC).If the goods sent by the agent are in bulk without any labels,or with labels that are too blurry to read,even if they provide a perfect material report,there’s a high chance that they’re "selling cat meat as lamb"—using a genuine report to match a batch of adulterated goods.
In addition,be vigilant against fake imported goods of the "one-day tour of the bonded zone".Some traders bring in low-quality domestic screw sets into the bonded zone,repackage them,and then send them out,pretending that they are imported goods.Check the port marks on the outer packaging andThe issuance date of the book (CO) is the key to uncovering this trick.
