| 1. Product Definition and Technical Due Diligence |
| Product classification | Material family | Identify whether the product is quartz-based engineered stone, cement-based artificial stone, resin-based composite, sintered slab, terrazzo, or another manufactured mineral surface. | Composition, manufacturing method, dimensions, and end use can affect HS classification, duty rates, product standards, and labeling obligations. | Attach a technical product description, bill of materials, production-flow summary, product photographs, and laboratory report to the customs file. |
| Potential HS heading | Customs classification | Artificial-stone articles may fall under different headings, commonly including Chapter 68 headings such as worked stone or articles of cement, concrete, or artificial stone. The correct subheading is jurisdiction-specific. | Incorrect classification can cause duty reassessment, customs delays, penalties, or import restrictions. | Obtain a binding or advance tariff ruling where available. Do not rely only on the supplier’s HS code or a previous shipment entry. |
| Product dimensions | Slab size and thickness | Record exact length, width, thickness, edge profile, surface finish, and dimensional tolerance for every SKU. Large slabs require special packaging and handling planning. | Small dimensional deviations can affect cutting yield, installation, container loading, breakage exposure, and customer acceptance. | Use a signed technical data sheet with tolerance limits, inspection method, sampling frequency, and rejection rules. |
| Physical performance | Quality parameters | Typical controls include water absorption, flexural strength, abrasion resistance, stain resistance, chemical resistance, flatness, color consistency, and visible defects. Limits must be agreed by product type and applicable standard. | Unspecified acceptance criteria make claims difficult to enforce and increase the risk of inconsistent batches. | Define measurable minimum or maximum values in the contract and require an independent pre-shipment inspection for high-value orders. |
| Health and safety | Respirable crystalline silica exposure | Cutting and finishing certain engineered-stone products can generate respirable crystalline silica dust. Worker-exposure rules differ by country and may apply to fabrication, installation, and workplace controls. | Importers, fabricators, and installers may face occupational-health, training, ventilation, personal-protection, and communication obligations. | Request composition data and safety documentation, verify destination-country requirements, and include safe-cutting and handling instructions with the shipment. |
| | 2. Global Shipping and Logistics Planning |
| Main transport mode | Ocean freight | Preferred for full-container loads
Use for dense, heavy, non-urgent cargo. Port-to-port planning commonly requires several weeks, excluding customs and inland delivery. | Lowest unit freight cost in most long-distance sourcing programs, but exposure to port congestion, transshipment, blank sailings, and schedule changes remains material. | Build a buffer into the requested delivery date, confirm the equipment type, and obtain written confirmation of free time, demurrage, detention, and terminal charges. |
| Main transport mode | Air freight | Normally unsuitable for slabs
Use only for samples, documents, small accessories, or urgent replacement items where dimensions and weight permit. | Air freight may be many times more expensive than ocean freight and does not eliminate customs, packaging, or product-compliance risks. | Use air shipment only after approval of an expedited-cost comparison and confirmation that the cargo is accepted by the carrier. |
| Container utilization | Weight and breakage balance | Artificial stone is dense, so the practical limit may be either container payload or available loading volume. Actual capacity depends on slab dimensions, crates, racks, packaging, and local road limits. | Overloading can create safety, carrier-acceptance, customs, and inland-transport problems. Under-loading increases freight cost per square meter. | Approve a container-loading plan showing gross weight, number of crates, center of gravity, lashing points, crate dimensions, and maximum axle weights. |
| Packaging | Export protection | Use rigid A-frame or equivalent support, moisture-resistant protection, edge guards, internal separators, impact protection, and visible handling marks appropriate to the cargo. | Poor packaging can cause edge chipping, slab cracks, staining, moisture damage, and claims that are difficult to attribute after delivery. | Require packaging photographs before loading, record crate condition at stuffing, and use shock or tilt indicators for high-value or fragile shipments where justified. |
| Transit-time planning | Port-to-port schedule | Use a route-specific planning range rather than a single promised date. A long-distance ocean movement may require approximately 25–50 days port-to-port, while regional services may be shorter. | Production completion, vessel departure, transshipment, discharge, customs clearance, and inland delivery are separate milestones. | Contractually define “on-time delivery” using the arrival milestone that matters commercially, and require milestone updates at booking, loading, departure, transshipment, arrival, and customs release. |
| Incoterms | Allocation of cost and risk | Use an Incoterms® 2020 rule that matches the actual logistics structure. FCA is often suitable for containerized cargo; FOB applies to sea shipments where delivery occurs on board; DAP or DDP requires careful importer-of-record analysis. | Confusing cost allocation with transfer of risk can leave insurance, export clearance, destination charges, or import tax uncovered. | State the named place precisely, specify who books transport, identify the importer of record, and list which charges are included or excluded. |
| | 3. Customs, Documentation, and Import Compliance |
| Commercial documents | Invoice and packing list | Documents should show seller and buyer, product description, quantity, unit and total value, currency, country of origin, gross and net weight, package count, marks, and agreed delivery term. | Inconsistent descriptions or values can trigger customs queries, valuation concerns, clearance delays, or data corrections. | Use a document checklist and perform a three-way match among purchase order, commercial invoice, and packing list before vessel departure. |
| Transport document | Bill of lading or sea waybill | Check shipper, consignee, notify party, container number, seal number, package count, cargo description, freight terms, and port details. | Errors can delay cargo release, create documentary discrepancies, or prevent timely customs and delivery instructions. | Require draft-document approval before issuance and retain evidence of the final document version. |
| Origin evidence | Country of origin and preference | Country of origin is not necessarily the country of shipment. Preferential tariff treatment, when available, normally requires origin rules and prescribed proof to be satisfied. | Unsupported origin claims may result in loss of preference, additional duty, penalties, or increased inspection risk. | Verify substantial-transformation rules, obtain the correct origin statement or certificate, and retain production and sourcing records. |
| Customs value | Transaction value | Declare the customs value according to destination-country rules, including relevant additions such as assists, commissions, royalties, packing, or freight where legally required. | Under-valuation can create penalties and audits; over-valuation unnecessarily increases duty and import-tax exposure. | Maintain a written valuation policy and reconcile invoice value, freight, insurance, tooling, samples, rebates, and related-party pricing. |
| Regulatory records | Product and safety documentation | Depending on destination and end use, documentation may include safety data, chemical composition, test reports, installation instructions, labeling information, and packaging or wood-treatment records. | Missing records may prevent sale, installation, customs release, or successful insurance and warranty claims. | Create a destination-specific compliance matrix before purchase order issuance and define document delivery as a contractual condition. |
| | 4. Contract Structure and Supplier Risk Control |
| Specification control | Purchase-order hierarchy | The contract should state which document prevails if the purchase order, drawings, technical data sheet, sample, and supplier quotation conflict. | Unclear document priority creates disputes over color, thickness, tolerances, packaging, and acceptance criteria. | Use a controlled specification annex and prohibit substitutions or changes without written buyer approval. |
| Quality acceptance | Inspection and rejection | Define inspection timing, sample size, inspection standard, defect categories, color comparison method, dimensional tolerances, and remedies for nonconforming goods. | Inspection only after installation may make replacement, labor, and consequential-cost recovery more difficult. | Use staged inspection: pre-production approval, during-production check, pre-shipment inspection, and destination verification for critical projects. |
| Payment terms | Cash-flow and performance exposure | Use payment milestones linked to verifiable events, such as approved sample, production completion, passed inspection, document release, or delivery. | Large unsecured prepayments increase exposure to delay, insolvency, quality failure, and shipment abandonment. | Limit advance payment where possible, use documentary controls, and reserve a final balance until agreed documents and inspection results are received. |
| Security instruments | Trade-finance protection | For large or strategically important orders, consider a bank-supported payment structure, performance security, or other legally enforceable protection appropriate to the transaction. | Security instruments can reduce counterparty and non-performance risk but may increase banking cost and administrative requirements. | Obtain legal and banking review before execution and specify issuing-bank requirements, expiry, claim conditions, and governing rules. |
| Change management | Material, process, and design changes | Changes to resin, mineral filler, pigments, curing method, production site, packaging, or subcontractor can affect appearance, performance, and compliance. | Unapproved changes may create batch inconsistency, warranty claims, or a different customs and regulatory profile. | Require advance notice, updated test results, a retained reference sample, and written buyer approval before implementation. |
| Warranty and remedies | Defect responsibility | Define warranty duration, claim notice period, evidence requirements, replacement or refund procedure, transport responsibility, and treatment of installation-related costs. | General warranty language may not cover hidden cracks, shade variation, moisture damage, or losses discovered after fabrication. | Separate product warranty from installation warranty and establish an evidence package containing photos, batch numbers, measurements, and installation records. |
| | 5. 2026 Supply-Chain Risk Dashboard |
| Freight disruption | Schedule reliability | Medium to high risk
Ocean schedules can be affected by port congestion, equipment shortages, weather, labor actions, route changes, and geopolitical events. | Late arrival can interrupt fabrication and construction schedules even when the supplier finishes production on time. | Use at least one qualified alternative route, maintain schedule buffers, and identify substitute inventory or local finishing options for critical projects. |
| Cargo damage | Breakage and concealed defects | Medium risk
Slabs and large panels are vulnerable to edge impact, flexing, poor lashing, vibration, moisture, and unloading damage. | Damage may be discovered only after unpacking or fabrication, complicating carrier and supplier liability. | Photograph loading and unloading, preserve packaging, record seal condition, and notify the carrier and insurer within the contractual claim period. |
| Currency exposure | Exchange-rate volatility | Manage contractually
Price risk depends on the invoice currency, payment schedule, freight currency, and destination-market selling currency. | Exchange movements can reduce margin even when the supplier price remains unchanged. | Use a defined pricing currency, validity period, adjustment formula, or approved hedging approach for long-lead projects. |
| Counterparty concentration | Supplier dependency | High risk if single-sourced
Reliance on one factory, one region, or one raw-material source increases recovery time after disruption. | A single failure can stop supply of matching colors, thicknesses, molds, or project-specific finishes. | Qualify at least one alternative source, retain approved reference samples, and avoid concentrating all critical SKUs with one supplier. |
| Insurance | Marine cargo coverage | Confirm whether coverage is arranged by the seller or buyer under the selected Incoterms® rule. Coverage terms, exclusions, deductibles, and claim procedures differ by policy. | Standard carrier liability may be limited and may not cover the full commercial loss or installation consequences. | Review the policy before shipment, insure the appropriate value, and confirm coverage for breakage, water damage, handling, storage, and transshipment where relevant. |
| Business continuity | Recovery planning | Critical projects should have an escalation process for production delay, customs hold, vessel cancellation, product recall, quality failure, or supplier insolvency. | Without predefined actions, teams may lose time deciding who can approve rebooking, replacement production, or emergency procurement. | Maintain a contact tree, alternative supplier list, approved substitute specifications, emergency freight budget, and documented decision thresholds. |
| | 6. Recommended Procurement Decision Rules |
| Supplier approval | Minimum qualification file | Collect legal entity information, manufacturing-site address, production capacity, quality certifications where applicable, test reports, export history, references, and financial-risk indicators. | Supplier quotations alone do not demonstrate production capability, compliance, or financial resilience. | Approve suppliers through a documented scorecard covering quality, capacity, compliance, logistics, financial stability, and corrective-action performance. |
| Sample approval | Reference standard | Keep a signed sample or approved digital reference for color, pattern, gloss, texture, edge, thickness, and packaging condition. | Natural-looking variation and batch variation can be disputed if no reference standard exists. | Identify the sample by date, batch, SKU, and revision. State whether the sample is a strict standard or an acceptable visual range. |
| Total landed cost | Cost calculation | Calculate product price, export charges, ocean or inland freight, insurance, duties, import taxes, customs fees, handling, inspection, storage, breakage allowance, and financing cost. | The lowest factory price may not produce the lowest delivered cost or the best project margin. | Compare suppliers using delivered cost per square meter or per usable unit, not only the quoted factory price. |
| Final go/no-go gate | Pre-shipment release | Release cargo only after confirmation of approved specifications, passed inspection, correct documents, compliant packaging, insurance, booking, and payment authorization. | A shipment that leaves before these checks may be difficult or expensive to correct. | Use a documented pre-shipment checklist with named approval owners and a “hold shipment” rule for unresolved critical defects. |
