04C-TPAT Audit

Customs-Trade Partnership Against Terrorism (C-TPAT) is one layer in U.S. Customs and Border Protection's (CBP) multi-layered cargo enforcement strategy. Through this voluntary public-private partnership, CBP works with importers, carriers, consolidators, licensed customs brokers and manufacturers to strengthen international supply chains and improve border security. The Security and Accountability for Every Port Act of 2006 provided the statutory framework for the programme.

• GTC has experienced C-TPAT auditors
• Evaluates clients against the C-TPAT standard and issues audit reports
• Covers importers, carriers, consolidators, customs brokers and manufacturers

05Inspection Service

Upon the request of the client or the buyer, GTC acts on behalf of the client to inspect and accept goods quality, delivery orders, purchase contracts and other relevant items, checking whether the supplier's goods meet contractual and other special requirements.

• Pre-production inspection：Inspectors examine, by random sampling, raw materials, initially processed products and spare parts before mass production.
• During-production inspection：Inspectors check semi-finished products on the line or just off it for flaws and deviations, report to the factory and provide effective means of correction.
• Pre-delivery inspection：Before manufacture and packing are completed (usually 100% produced and 80% packed), inspectors check quantity, workmanship, function, colour, size and packing details. Sampling follows ISO 2859 / ANSI/ASQC Z1.4 / BS 6001 / DIN 40080 and the buyer's AQL level.
• Supervision of shipment：After final random inspection before shipment, inspectors assist the manufacturer in confirming that packing meets proper cleanliness and packing conditions at the factory, warehouse or during container loading.
• Factory evaluation：According to client requirements, inspectors examine working conditions, production conditions, facilities, manufacturing equipment and methods, quality assurance management and personnel, then report — investigating not only issues that may lead to quality accidents but also providing rectification advice.

06Jewelry Inspection

GTC tests more than 100 kinds of jade and jewellery based on the relevant standards.

• Diamond grading: grading of non-mosaic and mosaic diamonds; personalised letters, numerals, Chinese characters and simple bitmaps can be engraved on the girdle
• Precious metals: purity and content testing of gold, silver, platinum and palladium articles (non-destructive and chemical methods), plus coating thickness testing
• Nickel release and hazardous elements: nickel release testing and determination of harmful elements in precious and non-precious metal articles
• Others: ornamental stone identification, corrosion resistance and firmness of coatings, testing of non-precious metals and ornaments

07Engineering Quality Inspection

In accordance with national laws and regulations, mandatory construction standards and design documents, GTC tests the quality characteristics of materials, components and equipment used in construction projects, as well as the quality and function of the project entity.

• Foundation and subsoil works：Static load test of bearing capacity for foundation and composite foundation; bearing capacity test of piles; integrity test of piles; locking force test of anchors.
• Main structure works (on-site)：On-site strength testing of concrete, mortar and masonry; thickness inspection of the steel reinforcement layer; structural performance of precast concrete components; mechanical properties of post-embedded parts.
• Curtain wall engineering：Airtightness, water tightness, wind pressure deformation and inter-storey deformation performance; compatibility inspection of silicone structural adhesive.
• Steel structure works：Non-destructive testing of weld quality; corrosion protection and fire protection coating inspection; mechanical properties of joints, fasteners and high-strength bolts; deformation detection of steel grid structures.

08Health & Safety Risk Assessment

Identifying hazards is an essential part of safety risk assessment. If the harms of safety accidents are not fully identified, it is impossible to assess the risk of each hazard or to control them effectively.

Safety risk assessment provides the baseline data for effective safety management, evaluates hazard points across environments and periods, and through educational, administrative, technical and supervisory measures makes every level of staff take safety seriously — so that most safety incidents can be avoided. It follows three steps: ① identify the hazards, ② assess the risks, ③ control and manage the risks.

• Hazardous materials: types of flammable/explosive materials, where and how many, and whether they are properly managed
• High-risk processes: work at height, high temperature, flammable operations and effectiveness of safety programmes
• Electrical safety: compliant installation, overloaded sockets, ageing wiring, anti-static measures, regular maintenance
• Housekeeping: accumulation of combustibles, misplaced materials, scaffolding stability
• Environmental hazards: immediate evacuation routes, ability to cut off power at once
• Alarm devices: availability and working condition
• Others: additional risks from contractors' tools and materials

09Labor Risk Assessment

Labor risk assessment is an authoritative, professional and systematic employment-risk solution. Through software application it provides comprehensive legal risk assessment and diagnosis for employers. GTC assesses all processes and procedures in the enterprise's employment management, so the enterprise knows its labor risks in advance, quantifies their possible impact and loss, and receives reference solutions to solve problems proactively.

• Comprehensively identify potential employment risks
• Analyse shortcomings in employment operation
• Assess probability of occurrence and possible negative impact
• Determine priority and sequencing of risk resolution and control
• Recommend risk solutions and countermeasures

10Product Quality Risk Assessment

Product quality risk refers to the possibility that product quality will be reduced or the product rejected by the customer due to various predictable or unexpected reasons. When certain defects have limited impact, or the impact costs less than delayed delivery and rework, a release decision arises in design review — this is product quality risk assessment.

• Effectively reduce company cost and resource waste
• Let designers focus on more urgent problems in development or production
• Eliminate unnecessary rework
• Involve technical, inspection and sales people so every problem is treated from the user's point of view

11ISO 9001 Quality Management System Certification

ISO 9001 is the world's best-known quality standard and the most widely used management model, based on a philosophy of continuous improvement. Whatever the size or sector, it is an excellent tool to improve your business, processes and leadership. An ISO 9001 certificate indicates that your company functions effectively in a systematic and customer-oriented way; yearly audits keep the certificate valid.

• Supports continuous improvement of your organisation and operations
• Helps meet clients' expectations for development, production and delivery
• Recognised all over the world — face global competition with confidence
• Valid external proof of quality efforts; improves staff participation and risk management
• Improves supplier relations and supports brand building

12ISO 14001 Environmental Management System Certification

An ISO 14001 certificate brings you the right tools for improvement and tells stakeholders of your responsible attitude towards environmental issues. Respect for the environment also brings competitive advantages — effective use of raw materials and energy is good for the environment and diminishes operating costs. A certified EMS helps you comply with legislation, recognise risks and environmental effects, and set environmental goals from a long-term perspective.

• Changes environmental thinking into action
• Helps to comply with legislation across the world
• Increases cost-effectiveness and improves risk management
• A strong signal of responsibility; supports brand building
• Promotes environmental awareness and participation; facilitates permits and government cooperation

13OHSAS 18001 / ISO 45001 Occupational Health & Safety Certification

Certification is based on the international OHSAS 18001 standard (now transitioned to ISO 45001), which aims to prevent accidents and illness in advance and to link health and safety issues with management, turning the focus from the number of single accidents to risk assessment and analysis. The certificate signals to your personnel and customers that you invest in a safe workplace. OHSAS 18001 is compatible with ISO 9001 and ISO 14001 — systems can be evaluated and certified separately or simultaneously for maximum synergy.

• Integrates occupational health & safety into everyday activities
• Prevents accidents, illness and occupational health problems
• Improves profitability through lower insurance costs
• Helps identify risks, improve working methods, motivation and well-being
• Improves collaboration, information flow and communication

14FSC Forest Management Certification

FSC Forest Management certification confirms that a specific area of forest is being managed in line with the FSC Principles and Criteria. To achieve it, the forest manager or owner contracts with an FSC-accredited certification body or joins a Forest Management Group; in either case the forest is audited to FSC's Forest Management standards. GTC also provides FSC Chain of Custody (COC) audit services.

15EU Forced Labour Regulation Compliance Audit (EU 2024/3015)

Regulation (EU) 2024/3015 prohibiting products made with forced labour on the Union market was published on 12 December 2024 and entered into force on 13 December 2024. It applies from 14 December 2027: products made with forced labour, in whole or in part, may not be placed on, made available on, or exported from the EU market. It covers all products (services excluded), all origins and all economic operators — manufacturers, importers, distributors, retailers and online sellers.

Enforcement is risk-based. Where suspected forced labour occurs outside the EU, the European Commission leads the investigation; where it occurs within a Member State, that state's authority does. The preliminary phase lasts 30 working days and a formal investigation should normally conclude within 9 months. If a violation is established, the product is banned from the market and must be withdrawn, delisted or disposed of (or the forced-labour component destroyed where it is replaceable); the decision is recognised by all 27 Member States, and penalties are set by each Member State.

• 13 Dec 2024 · Regulation (EU) 2024/3015 enters into force
• 26 Jun 2026 · European Commission publishes implementing guidelines C(2026) 4386 final
• 14 Dec 2027 · Full application: forced-labour products barred from the EU market

• Supply-chain risk screening：Maps forced-labour risk by product, process, origin and supplier tier, flagging high-risk points such as labour brokers, dispatched workers, student workers, piece-rate overtime, deposits and document retention.
• On-site audit：Assessed against the three elements of ILO Convention No. 29 and SMETA / ETI methodology: recruitment and brokers, identity documents and deposits, freedom of movement, hours and wages, voluntary overtime, young workers, disciplinary measures, dormitories and site management.
• Document and record review：Consistency checks across employment contracts, attendance and payroll records, broker agreements and fee receipts, dispatch / internship / student-worker agreements, and resignation and grievance records.
• Extended supplier review：Tier-1 and tier-2 suppliers, subcontracting and outsourced processes, identifying hidden risk in sub-contracted and home-based work.
• Corrective action and re-audit：Non-conformity list and CAPA plan, followed up and re-audited to close the loop.
• Audit report and evidence pack：A bilingual audit report with site photographs, interview records and sampling notes — ready to submit to EU customers, importers or authorities.

16EU Deforestation Regulation (EUDR) Due Diligence Verification

Regulation (EU) 2023/1115 on deforestation-free products (EUDR) repeals the EU Timber Regulation (EUTR). It covers seven commodities — soy, cattle, oil palm, wood, cocoa, coffee and natural rubber — and derived products such as leather, chocolate, tyres, furniture and paper. Operators and traders must show that products are simultaneously: ① deforestation-free, i.e. produced on land not subject to deforestation or forest degradation after 31 December 2020; ② produced in accordance with the relevant legislation of the country of production; ③ covered by a due diligence statement (DDS).

Application dates (as amended by Regulation (EU) 2025/2650): large and medium operators from 30 December 2026; micro and small operators from 30 June 2027, except micro and small operators already covered by the EUTR, which remain at 30 December 2026. Delegated Regulation (EU) 2026/2102 of 17 September 2026 amended Annex I: certain palm-oil derivatives were added (applying from 30 December 2027) while raw cattle hides and skins, certain vulcanised rubber articles and soybeans for sowing were removed. The final text in the Official Journal and the HS/CN codes in Annex I prevail.

How the audit works: EUDR is built on three due diligence steps — information collection, risk assessment and risk mitigation — and competent authorities set inspection rates according to country risk benchmarking (low / standard / high). The geolocation of plots in the DDS (polygon or point) is decisive: accuracy, plots crossing boundaries and completeness of coverage determine whether the statement stands. GTC traces the supply chain through to plot-level verification, so that the DDS rests on evidence that can be checked rather than on self-declaration alone.

• 29 Jun 2023 · EUDR enters into force
• 23 Dec 2025 · Regulation (EU) 2025/2650 published — obligations simplified, application postponed
• 30 Dec 2026 · applies to large and medium operators (and SMEs already under the EUTR)
• 30 Jun 2027 · applies to micro and small operators

• Product classification and supply-chain mapping：Determines whether products fall within Annex I by HS/CN code, and maps the role and responsibility of each link from forest or farm to exporter (operator / trader / downstream operator).
• Plot geolocation verification：Verifies plot boundaries in WGS84, corrects coordinate systems and format conversions (including CGCS2000 and Gauss-Krüger local coordinates), checks area against species or crop, and compares satellite imagery for deforestation or degradation after 2020.
• Legal compliance evidence review：Reviews the completeness of felling permits, land and tenure rights, transport and processing documents, tax receipts, and labour rights and free, prior and informed consent (FPIC) under the law of the country of production.
• Risk assessment and mitigation：Assesses risk against country benchmarking, supply-chain complexity and commodity characteristics, producing risk levels, mitigation measures and retained records to demonstrate due diligence.
• DDS submission support：Supports preparation of the data a DDS requires (commodity and quantity, country of production, geolocation, suppliers, upstream reference numbers) and cross-checks the filing against audit findings.
• Management system and training：Establishes an EUDR management procedure, supplier approval and annual review mechanism and record-retention rules, with tailored training for procurement, export sales and quality teams.
• Audit report and evidence index：A bilingual audit report, geolocation schedule and evidence index — ready for DDS filing, customer due diligence and competent-authority inspections.
