As the transit hub for imported high-end European and American fasteners to mainland China, HK Customs updated subdivided HS classification codes for mechanical standard parts in 2026, distinguishing domestically produced fasteners and original overseas brand parts. Import brands including HUCK, schnorr, PEM and Hard-Lock are assigned separate sub-codes, with synchronous adjustments to customs documents, tax calculation and inland transit clearance procedures. All customs rules and import compliance clauses in this article are extracted from official HK Customs website and EU REACH annex list, objectively analyzing the full import procurement process of overseas EPC contractors transshipping via Hong Kong, solving high-frequency problems such as misclassification, missing documents and unqualified site acceptance for foreign trade buyers.
| Import Fastener Category | Sub HS Code | Mandatory Customs Document | Extra File For Overseas Projects |
| HUCK Lockbolts | 7318160000 (High Tensile Locking Fastener Sub-item) | Original Certificate Of Origin, Mill Material Report | Copy Of CE Machinery Safety Certificate |
| Nord-Lock / schnorr Anti-loosening Washers | 7318220000 (Spring Steel lock washer Sub-item) | Original RoHS & REACH Test Report | Original Vibration Fatigue Test Certificate |
| PEM Self-clinching Studs & Snap Fasteners | 7318190000 (Special Thread Parts For Thin Sheet) | Original Product Catalog & Dimension Comparison Sheet | Thin Sheet Assembly Mechanical Verification Report |
| UNC/UNF Stainless Micro screws | 7318159000 (Non-standard Imperial Thread Parts) | Spectrum Material Certificate, Halogen-free Certificate | Drawing Matching Statement For Client Project |
1. Direct Shenzhen-Hong Kong Land Transit: Suitable for small batches under 500kg including import samples and project supplementary orders, customs clearance within 1-2 working days, inland inspection probability around 12%, ideal for import fasteners matching 3C and industrial control equipment; 2. Full Container Consolidated Warehouse Transit: For bulk import locking fasteners of overseas large infrastructure and wind power projects, supporting split delivery to multiple inland destinations, unit logistics cost reduced by 18% on average, with 3-7 days warehouse stocking cycle requiring advance procurement planning.
First, confused HS classification, categorizing special imported locking fasteners into ordinary screw sub-items triggering manual inspection; Second, incomplete original REACH material reports without SVHC high-risk substance list for EU-origin goods; Third, inconsistent batch numbers between certificate of origin and goods due to incomplete batch traceability by overseas brand agents; Fourth, missing CE supporting documents for overseas EPC projects, failing clearance for equipment complete machine import to EU.
1. Original factory sealed packages cannot be split, each carton attached with original factory test certificate, bulk repacked goods rejected directly; 2. Anti-loosening and high tensile locking fasteners must provide original million-cycle vibration fatigue data, third-party alternative test reports are not accepted; 3. Import parts for coastal & offshore overseas projects shall additionally provide factory IEC60093 alternating salt spray warranty file; 4. All imperial standard import fasteners must be supplied with matching imperial torque installation specification for site supervisor filing & verification.
