Some frequent issues include:

• Vague or generic descriptions on invoices like “parts” or “clothing,” which are not sufficient for correct HS classification.
• Discrepancies between quantities or weights on invoices, packing lists, and B/Ls.
• Incorrect Incoterms or currency not matching the sales contract.
• Missing or incorrect certifications for regulated goods (INVIAS for some materials, INVIMA for health products, ICA for agricultural items, etc.).

To prevent this, Top Logistics Ltd:

• Provides invoice and packing list templates aligned with Colombian customs expectations, including Spanish descriptions where appropriate.
• Pre‑checks supplier documents in China and corrects inconsistencies before loading.
• Coordinates with your Colombian customs broker to validate HS codes and any licensing or sanitary requirements for your products before cargo departs.

This reduces the risk of DIAN sending the shipment to a more complex channel or demanding corrections while the container accumulates storage.

For DG and chemical cargo:

• We review Safety Data Sheets (SDS) to identify UN numbers, classes, and packing groups.
• Packaging, labelling, and documentation are checked for compliance with IMDG (sea) or IATA (air) rules.
• We ensure carriers and ports along the route accept the DG class and respect any stowage or segregation requirements.
• In Colombia, we coordinate with your broker to meet local environmental and safety regulations and obtain any necessary permits or registrations.

Because DG mishandling can result in fines or refusal at ports, involving Top Logistics Ltd early in the process is essential so we can confirm feasibility and advise on safe packing and routing.

Not necessarily. Combining them reduces freight cost per unit but introduces risks:

• High‑value goods in a mixed container can increase pilferage temptation and may attract closer customs scrutiny.
• If customs or other authorities decide to inspect or hold the container because of one product line, all cargo in that container is delayed.

A better strategy is often:

• FCLs dedicated to general or low‑value goods, optimised purely for cost.
• Separate containers or LCL lots for high‑value or sensitive items, where we can add more security, seals, and potentially faster handling or different routing.
• For the top‑priority or most expensive items, airfreight may be justified.

Top Logistics Ltd can model cost and risk for different grouping options so you see the trade‑offs clearly before deciding.

Some practical levers:

• Move predictable base volumes by FCL on standard services; use LCL or air only for true demand spikes.
• Concentrate orders from multiple suppliers through origin consolidation so you pay port, documentation, and haulage charges fewer times.
• Use Chinese ports that minimise inland trucking from your factories and have strong Asia–WCSA connections.
• Optimise packaging and carton size so that your containers load at a high, safe utilisation level.
• Share a rolling forecast with Top Logistics Ltd so we can negotiate better rates with carriers and avoid last‑minute premium bookings.

We can review your last 6–12 months of data and propose a specific optimisation plan, quantifying expected savings and any impact on lead times.
