In the Investment Casting (Lost Wax Casting) industry, particularly for stainless steel and alloy steel, holding industry-specific certifications is more than just a technical requirement—it is a mandatory “global passport” for exporting to the USA, EU, Japan, and South Korea. Without these, products may face customs rejection, lost contracts, or additional inspection costs amounting to 25–35% of the shipment value.
At CDL LOST WAX CASTING JOINT STOCK COMPANY (Dong Nai) – an ISO 9001:2015 certified facility (Certificate No. 9199302839085-QMS, issued March 13, 2025) – we have supported hundreds of export shipments in achieving prestigious certifications: FDA/HACCP/NSF (Food & Beverage), ABS/DNV/LR (Marine), PED 2014/68/EU (Pressure Equipment), and IATF 16949 (Automotive). With our 100% NDT workflow, spectrometer material verification, and MTC Type 3.1/3.2, our export compliance rate stands at 99.5%, helping global partners like THACO, Yamaha, Hyundai, and Ford increase their contract values by 30–50%.
1. FDA / HACCP / NSF – Food, Pharma, and Sanitary Standards
- FDA 21 CFR 177.2600: Ensures materials do not leach heavy metals or contaminate food. Typically, SS 316L is the mandatory grade.
- HACCP: Controls 7 Critical Control Points (CCP) from raw materials to final surface pickling.
- NSF/ANSI 61: Ensures no chemical migration into potable water.
At CDL: We implement a closed-loop 5-step cleaning process (Nitric+HF Acid $\rightarrow$ Neutralization $\rightarrow$ High-pressure rinse $\rightarrow$ Double purified water rinse $\rightarrow$ 100°C Drying) and verify surface roughness ($Ra \leq 1.6$ µm) using Mitutoyo SJ-410 to meet these stringent hygiene standards.
2. ABS / DNV / LR – Marine and Shipbuilding Classifications
- ABS (American Bureau of Shipping): Requires 100% NDT (PT + UT/RT), post-heat treatment mechanical testing, and ASTM A351/A217 compliance.
- DNV (Det Norske Veritas): Includes mandatory Ferrite testing for Duplex 2205/2507 grades.
- LR (Lloyd’s Register): Focuses on fatigue strength and salt-mist corrosion resistance.
At CDL: Our marine propellers undergo comprehensive UT + RT (Ultrasonic and Radiographic) testing, ensuring they pass ABS/DNV inspections on the first attempt.
3. PED 2014/68/EU – Pressure Equipment Directive (EU Market)
- Module H: Full quality assurance from design to final production.
- EN 10213: Mandatory standard for cast steel/stainless steel.
- CE Marking: Required for all pressure-containing components entering the European Economic Area.
At CDL: Our valves and fittings comply with PED through rigorous Hydrostatic Pressure Testing (1.5x working pressure) and NDT per EN 10213, allowing seamless export to Germany and France.
4. IATF 16949 – Global Automotive Quality Standard
- PPAP (Production Part Approval Process): Component approval prior to mass production.
- FMEA + SPC: Risk analysis and Statistical Process Control.
At CDL: Automotive gearbox components achieve IATF compliance through FMEA integration across all 10 casting stages, maintaining a defect rate of <50 ppm.
5. Comparative Summary of Certification Requirements
| Certification | Industry | Preferred Materials | NDT Requirement | MTC Type |
| FDA/NSF | Food/Pharma | SS 316L | 100% PT | 3.1 |
| ABS/DNV | Marine | Duplex, Alloy 4340 | PT+UT+RT 100% | 3.2 |
| PED 2014/68/EU | Pressure Parts | Stainless/Steel EN 10213 | PT+UT+RT | 3.1/3.2 |
| IATF 16949 | Automotive | Alloy 4140/4340 | PT+UT | 3.1 |
6. Proven Success Stories at CDL
- Case 1 – Food Industry (Yamaha): Secured FDA/HACCP for SS 316L gas components. Results: Export volume to the USA increased by 50% with an added contract value of 1.8 billion VND/year.
- Case 2 – Marine Propellers (THACO Marine): Achieved ABS/DNV for Duplex 2205 parts through 100% NDT and MTC 3.2. This eliminated the need for third-party inspection upon arrival in South Korea and Singapore.
- Case 3 – Offshore Oil & Gas: Achieved PED + CE Marking for Super Duplex 2507 valves ($PREN$ 42, 48% Ferrite), securing a 2.5 billion VND contract for the EU market.
Conclusion
Certifications like FDA/HACCP, ABS/DNV, PED, and IATF 16949 are the specialized benchmarks that allow Vietnamese Investment Casting products to compete globally. At Lostwaxcasting CDL, our ISO 9001:2015 foundation and professional certification support ensure that every export batch is “International Standard – Cost-Optimized – Sustainably Certified.”
